Great evolution of the Sena brand
OK, it took me a while to write a review for this product because I really wanted to use it, figure out the issues, and try to solve them, instead of blasting off a review in frustration.

Yep, the 20s has much improved sound, range, and noise cancellation. I have both an SMH10 and a 20S, so I think I have a good basis for comparison. It's a solidly built product. I like the new helmet mount. It feels a bit more solid than the SMH10. The antenna needs getting used to. It's not flimsy, but coming from the SMH10, which doesn't have an antenna, I forget to raise it most of the time.

Which brings me to the first "con" of the design. You may have read many reviews about choppy intercom or music or GPS sound. First of all, make sure to upgrade the firmware to the latest version (1.2 at the time of this writing). Secondly, apparently for smooth functionality of the 20S, you *MUST* have the antenna raised.

As with most 1st-generation devices of any kind, it takes a bit to smooth out the rough edges. Thankfully, Sena has great customer service, and appreciates feedback and questions to help them improve.

Why did I upgrade from the SMH10? Mainly for the new audio multitasking feature. I usually ride lead for my group, and the SMH10 allows the intercom or the GPS directions to come through the audio, not both. The 20S audio multitasking advertises that it seamlessly blends both signals simultaneously.

Here's the 2nd (sort of) "con": getting this feature to work correctly. Right out of the box, and after upgrading to the latest firmware, I couldn't get audio multitasking to work properly. I got dropped intercom, choppy audio, and no GPS directions. After contacting Sena support, they had me do a factory reset, remove the pairing from my phone, and start fresh. After doing that, I got audio multitasking to work flawlessly! Now I get music in the background while on intercom with my friends, and my GPS directions seamlessly overlays itself over all the signals! Yay!!

I gave this product 4 out of 5 stars because it's a bit finicky to setup, and some features, like the group intercom, only works with other 20S units. You can still have multi-point intercoms like the SMH10, but I still would have liked a 1-button connection to everyone in my group.

The voice commands work pretty well. Noise, of course, plays a role in how well the 20S interprets your commands. I've found the boom mic to work best (I use a Nolan N85 helmet).

All in all, I really like this product and will recommend to others, especially to ride leads due to the audio multitasking feature.

Best communicator out there
I ordered a new Icon Alliance Dark and wanted to get a bluetooth communicator so that I could listen to music, take phone calls (I'm practically always on-call at work and "I was out for a ride" doesn't go over well when I fail to answer the phone), and talk bike-to-bike when my wife and I go for rides.

My previous experience with bluetooth communicators have all been products by a different brand (rhymes with lardo). I did not really have any issues with them except for the price as well as the lack of issue that is found in many (most?) bluetooth communicators.

The Sena 20S isn't the cheapest thing in the world, but for the quality, performance, and included accessories it has a good bang for the buck factor.

With most similar products you typically get the communicator itself, a microphone (usually boom and wired), headphones, helmet clamp, and a stick mount for helmets that the clamp doesn't fit. With the Sena 20S you get all that and more. Also included in the box were a car charger, a second (wired) boom mic, auxiliary 3.5mm audio cable, as well as an assortment of velcro pieces to help mount everything in place. Basically, it is all the stuff that comes in the Sena 20S Supplies Kit that can also be purchased separately.

Installing the 20S on my Icon Alliance was a snap. My Schuberth C3 makes it very difficult to add a communicator because the clamp mounts don't work so hot and the sun visor lever make using a stick on mount more challenging than most (but they will be happy to hook you up with their C3 specific SRC communicator). The helmet clamp works just fine on the Alliance and the 20S feels rock solid. The microphone and headphone wires all tuck away neatly, though for my particular wire routing preference I'd have liked the microphone wire to have been an inch or two longer.

I'm no audiophile but I have no complaints about the sound quality the speakers provide. Sure, they aren't what you'd call bass rich but I've heard (much) worse. The volume is loud enough that I had no problem listening to the Cult's Fire Woman at freeway speeds on my cruiser, which doesn't have a windscreen. I have not made any phone calls yet but Siri is able to understand my voice commands just fine. I've not used the built in voice commands since everything I need to do can mostly be done through iPhone's Siri.

A great feature of the 20S is that you can have two cell phones paired at the same time. This is a nice touch for those of us who have to carry not only their personal phone but also a business one as well. Now I never have to choose between which phone I want to have paired to my headset.

The FM radio works well and I did not encounter any reception problems. I wish it would also receive HD radio since there are some HD only stations I like to listen to but it's hardly a deal breaker.

I'm looking also forward to being able to go for a ride and use the bike to bike intercom to talk to my wife. She has a different brand communicator but thanks to the universal intercom we can still talk to each other. A big problem with earlier communicators was that everyone in your group had to have the exact same brand and I'm glad we are moving past that. It was akin to having an iPhone that only made phone calls to other iPhones.

Finally, the thing I noticed first when I pulled the 20S out of the box was that it seemed like a very well built item. The helmet clamp felt very solid and not like the flimsy plastic clamps of other brands. The actual communicator itself gives a sense of confidence that it will last for the long haul.

I'm a technology geek so I'm all about having the latest toys and gadgets, but I look forward to keeping the Sena 20S on my helmet for a long time.

Was really looking forward to getting the 20S
When the 20S was announced, I was so excited about upgrading from my older SMH-10R. So much so, in fact, that I encouraged my touring friends to pre-order theirs, too. That has turned out to be somewhat of an embarrassment. It truly is painful for me to write this review. But we've been waiting almost 5 full months for fixes for the most glaring issues.

We received out 20S units in late June 2014. Immediately we noticed problems with an electronic whine/buzz in connected earbuds. We embarked on a 4,000 mile trip on July 4th. That's when the shortcomings of the 20Ss really hit us. The earbud buzz/whine was tolerable. But the other flaws were not. We ended up spending HOURS, literally HOURS fiddling with the units. In the course of the 10-day trip, they worked properly for maybe 30 minutes. The rest of the time we were fighting intercom outages and loss of intercom every time any of our Zumo units alerted or gave driving directions. We had to pull over at least three times per day to see if we could resolve the problems by doing things like powering up, resetting, reconnecting, etc. Every evening, we worked with the units to see if we could determine if the issues were due to our learning curve or due to deficiencies in the firmware. By the end of the trip, some of the group simply turned their 20S OFF and refused to be bothered by them any more.

The worst of the issues was the 20Ss randomly dropping Intercom to one or more in the group of 4. The only way to determine if communications was working was to ask, "Can anyone hear me now?" At least 10 times per day, the answer was silence. Hmmmm, guess no one could hear me. That resulted in many miles passing under our wheels while we poked at the JOG button, turned the unit ON and OFF and back ON, trying, trying, trying to restore communication between the four of us. We only had all four units intercomming for possible 2 hours TOTAL out of the 10 days of 10 hours per day riding. There was always someone missing.
Sometimes, this was caused by the units simply turning themselves OFF. No button pushing required. Silence might indicate that the unit had powered itself off with no notification by the Sena lady. Turns out, it does it all the time; sometimes within 5 minutes of connecting with another 20S. We were constantly calling,"can you hear me now".

Occasionally, we'd succeed in reestablishing communication after a half hour or more of riding and trying. Had no idea why.

The other issue that affects operation is that the A2DP port is meant for the phone to give it highest priority, I guess. However, everyone I know pairs their Zumo GPS as a phone so that the XM radio, audio books, and MP3 player works. That would be just fine, except every time the Zumo alerts or gives driving directions, intercom is blanked out . . . sometimes never to return. It would happen at the most critical times of our trip . . . like when looking for a restaurant or gas station in an unfamiliar area. Instead of being able to communicate our intentions with each other, the GPS blanked out the intercom. We had to resort to hand signals.

OK, now the good.
The audio quality is phenomenal. The wind noise filtering is like no other. One can ride with a half face helmet and his/her transmitted audio is 100% noise free! Wow!

The ability to use the phone is very good. My wife cannot tell whether I'm at 80 mph on the Interstate or parked at a gas station. It's that good.

At the time of this writing, I'm in hopes that Sena will address the issues that their customers have brought up on the Sena forum. They have good technical support people, but they can only help with the units as they have been produced. They cannot help with the problems and priorities between functions.

I must say that the factory support is as good as it can be. The four of us that bought in June all had our 20Ss replaced with new ones when we complained about the buzz in the earbuds and the lack of FM radio operation. Both of those issues were fixed with hardware changes and didn't cost us anything except a little inconvenience. I'm not sure whether or not the development team is working on the other issues. Only time will tell.
I sincerely want my Sena 20S to work reliably and am holding out for firmware changes that will address the issues we're having.

Firmware updates could make this perfect!
After a long wait I finally got my 20s dual pack! The build quality is nice, it feels a bit cheap at first but I think it will hold up. It is water resistant, and I've already had mine in the rain with no troubles. The FM radio is nice, but it doesn't pick up stations that well, and the antenna does not help at all. Also flipping the antenna up will activate the voice prompt, so every time you put it up you have to say cancel. When flipping through preset radio stations the voice tells you what preset and what channel you are on, problem is, the voice is very quiet, and when you're riding you might not be able to hear it at all. Audio quality overall is good, intercom quality seams a bit better than radio, but the speakers do both well. The jog dial is easy to use for the most part... but if you want to set your radio station presets and speed dial you almost have to use the app available for Android or Apple , but not windows. With out the app I never would have been able to set the radio presets using the jog dial. It comes with a few mic options, but the boom mic is recommended, and works fine for me. The side tone ability is cool, it plays your voice through the speakers so you can hear yourself talk, not something I'll use often but nice to have as an option. Also, there is an external mic that allows you to hear whats going on around you better, I.E stopped and trying to talk with someone, you can leave your helmet on and just hit the button to turn on your external mic. I am still having some problems getting it to work correctly with my Sena Bluetooth backpack. The audio consistently drops out, and will only work in normal mode, I'm not sure if this is a problem with the 20s or the backpack. Overall, it's a great product, it has a few bugs as I would expect from any industry first. I think most of those bugs could be fixed with a firmware update in the near future.

Best headset device
I have used three different devices. The Sena 10 being the latest before this one. The 20s is by far the best sounding for music or anything else. It sounds like a really good pair of headphones with Bluetooth music. More bass then the 10 and a lot clearer. The 10 didn't have any bass. The Sena 10 is a great unit but this one blows it away. The Sena 20s is a great unit that is easy to use and install.

Good, but could be even better
I've used this headset almost daily since late July. To start, I'll begin with installation. I know that Sena cannot take into account all helmet mounting methods, so I cannot knock them too much for the mount not working with my Nolan N105 (that's more an issue with Nolan, as I believe their purposefully build their helmets to prevent using third-pasty comm systems. Anyway, it took some creative cutting but I was able to mount the unit.

After updating the unit (that also took a while to learn their system and download the necessary updates), I finally got the unit up and running. Ever since, the software has been rock solid. Not issues pairing to my iPhone (5, or 6+).

Sound quality is good. Much better than the Cardo Q2 that I was using previously. Not a whole lot of base, but enough volume that I can hear the music very clearly at 75 mph with very good quality earplugs in.

Volume adjustment is quick (once I learned which direction to spin the wheel!), and selecting the multiple modes are a snap.

Pairing to another unit (SMH10) was good, and the range was decent. My friend didn't get too far away from me, but I'd say 100 yards at most on backroads and we could still hear each other clearly.

One of my biggest gripes has been battery life, as I could use my Q2 for almost 1.5 12-hour days on the bike before I needed to recharge it. The 20S can barely last 8 hours, BUT, you can plug the unit in while riding and it'll not only continue running, but charge as well. That's good for me! I can just plug it in when it gets low and keep riding.

Overall, a good little unit. Could be better, but I'm happy with what it is.

worked good for a little while
- Good for 2 up conferencing
- Good Bluetooth - Cellphone for music - better than average sound quality

- The back started separating fro the main unit, leaving the voice command activation not functioning.
*** Fortunately, Revzilla stood behind their product and issued a full refund. ***

- Expensive
- Voice activation works about 70%
- Radio sucks / worthless and radio sound quality is 'tin' sounding

I love my sena!
I upgraded from SMH 10 to the 20s and I love it. Easily one of the best features is the ability to overlap talking and music. For my friends and I this is perfect since we all go silent heading into the twisties so for the music to get louder when no one is talking is perfect. Also you are able to connect to more then ten other riders if you are going to be riding in formation. This can be done using "the daisy chain" technique.
Initially I had a bit of difficulty figuring out all of the controls so I would recommend playing with it when off the bike so you don't have to sacrifice your safety.
These are the best units you can get for riding and I highly recommend them. It will forever change your riding experience.

Easy to use, excellent clarity
I have to say, this bluetooth headset exceeded my expectations. Paired with some NoNoise ear protection it works perfectly. There is a little less bass than a good set of ear plugs, but the clarity is worth it.

Intuitive controls, and the voice control is easy to use. The app is great as well.

Phone calls are easy to make (be sure to set up the speed dial); my wife couldn't tell I was on the bike at all!

Good enough, but not great.
To be honest I don't really want to recommend the 20S, but I can't completely knock it either because it serves a purpose and I believe probably does it as well or better than most. My only other personal experience with a bluetooth unit was the one made specifically for my Nolan helmet. It completely crapped out on day two and I sent it back.

It's huge, but you get used to it. The voice commands are convenient when they work, which is frustratingly infrequent: that seems to be the microphone, not the software. I prefer to use the buttons to command the unit now anyway. Once you learn what does what, which is nicely simple, it's easier and more reliable. I have to periodically use the reset function to fix the sound quality or some other glitch, but that's easy; too frequent for my tastes but acceptable in the age of digital everything that is pushed to market too quickly. Carry a paper clip; you will thank me.

Installation was pretty straight forward. I had to use the adhesive mount, and they take no responsibility for it's use of course even though they provide it. It has lasted for 14k miles through all sorts of weather, temps from 32 to 105, and it seems fine. The sound quality and level are fine even at highway speeds for the most part. Occasionally, it will sound scratchy or tinny and distant; grab the paper clip, reset it, and it should be fine. I've been through some good rain and it hasn't shut down, but it has a feature that's supposed to preventatively shut it down in the event it gets too wet.

I don't use it for phone calls or intercom since I'm riding solo. I thought I'd use the radio, which works well, but I don't. I listen to audiobooks and music from my phone and accepting the criticisms above it works well and I'd rather have it than not I suppose. Especially now that I just use the buttons. Not a glowing or scathing review, I know, but hopefully it will help out.

Since the new BMW Nav 5 system doesn't have an audio jack, I was forced to retire my Autocom that I was used to. The Sena functions and integrates seamlessly with the bike, I-phone for music, directions and phone calls. The battery last for days and works well with summer and winter gloves. Would purchase again in a heartbeat.

We were referred to the Sena units by Revzilla Sales staff. We need a communication systgem that can be fitted to a Shoei Neotec Helmet, a Schuberth C3 pro helmet, and a universal mount helmet. your rep suggested Sena as reasonably easy to use and having models for all three applications that will work together.

Couldn't wait for the new model :) Hitting the road...

This device seems to have all the features I need. Now lets see how good it sounds once I have it installed.

To pair with my wife's Sena 20S
Gunnar D on Mar 10, 2017
Bought this model because of Sena's reputation and the universal pairing capabilities.

Good reviews and a lot of features.

I purchased a year ago and I love it. I listen to FM radio on the way to work and stream music from my phone on longer trips. I am yet to use the 2 way communication yet.

Group riding is no fun without them... awesome device!!

My first sena stopped working about 8 months after I got it. I was riding home and it started raining and I found out the hard way that even though they claim to be rainproof they are not. I sent it to sena and they replaced it. I just wish they were rainproof like they claimed to be.

I wanted a good Bluetooth setup because I wanted to move away from earbuds and use actual ear plugs for riding to protect my hearing. The reviews are very good, and this has some great features. I feel like this will remain relevant for a long time. Decided to get this over the 10R.

Purchased because I had to upgrade from my Smh-10 in order to use my Freewire. I really wish the Freewire worked with the SMH-10. As for the 20s it is awesome and provides better sound quality and more functionality than the SMH-10.

Best in class & several friends recommendations from their personal experience.

Buying for my son, i already have one and love the quality and ease of operation.
Ted B on Jan 29, 2017
I wanted a comm unit that would allow clear sound and easy controls. This appliance has proven itself as the perfect tool for listening to music as well as communicating with others. The Bluetooth connection with my phone is so good, that the party on the other end never even realizes that I'm riding during the call. I have gone for over 11 hours in a day without having to recharge.
Will W on Jan 28, 2017
This thing got way too much going on with it and all the tapping on the side of your helmet. Was hoping for a more voice activated system.
Ken M on Jan 23, 2017
Researched the best headsets, and I went with the 20S
Orlando V on Jan 22, 2017
One of the best purchases I have ever made, loud, clear, battery last for a great amount of time!
Anthony A on Apr 27, 2017
Wanted to get a Sena for communicating and listening to music. I was deciding between this and the SMH-10 but decided on this one because of the audio multitasking ability. I may have paid a price for it, but it's packed with features that I expect to last me a long time.
Paul L on Apr 22, 2017
I've seen sites where this was expected to be released in April, then May, and now, June. Any word on why the release continues to be backed up?
A shopper on Apr 28, 2014
BEST ANSWER: Very limited quantities (less then 300 for all of the US) are coming in by mid-June. All of quantities coming to RevZilla are spoken for in pre-orders. SENA expects to have good availability and to be able to fulfill all of the pre-orders by mid-late July.
Two things… First, are there separate volume controls for the intercom and music? And if so, how does this feature work??
I’m coming from a J&M Bluetooth headset and that was a huge feature for me, having buttons for the Bluetooth volume, and a dial for the rider/passenger intercom (which was corded) so they could be adjusted independently (turn the wife down and the music up for example)
Secondly, (and this is more of a curiosity really) when plugging in earbuds, does the sound cut out on the speakers or do the speakers and earbuds play simultaneously?
Thanks very much for the help!
A shopper on Nov 8, 2014
BEST ANSWER: The volume of the intercom is independently from the volume of the music so adjusting the volume of the intercom does not affect the volume of the music. Secondly, plugging in a pair of 3.5mm earbuds will disable the connected speakers.
Has the firmware update been released yet that will allow this to pair with Scala or Cardo units? Specifically, at this time, August 2015, will this pair with a Schuberth SRC, 2015 edition?
Lou C on Aug 9, 2015
Is it compatible to work wirelessly with my 2014 Boom 6.5 system on my Harley??
A shopper on Apr 19, 2014
BEST ANSWER: Ive asked the same question, and the short answer is no. According to my connect at my local Harley Dealer who spoke with a Sena salesman, if you buy the SENA SM10 connect that to the bike, then connect the 20S to that it will work.....
Can the 20S be charged on the bike while using it if it becomes necessary?
A shopper on Mar 3, 2014
BEST ANSWER: Yes. As with all other Sena products, the 20S can be charged while it is in use.
Hi, I´ve been using the 20s for almost 3 months. The intercom works perfectly and the sound quality is awesome. The thing is that I´ve been having some problems while listening to music, its working perfectly ansuddenly a big beep appears and the only way to end it is my turning it off. This has been happening more often, and its really annoying. Has anyone experienced this? How can I fix it? Or do you think that my device is defective?
A shopper on Feb 2, 2015
BEST ANSWER: It sounds like a software issue - I'd try to flash the firmware to the newest release and if that doesn't work revert it back to a known good version. Have you downloaded their update utility?
Will the new 20S be able to read and compose texts for the iPhone?
A shopper on Mar 16, 2014
BEST ANSWER: Yes. The 10 does also...
I currently use a wired intercom with a hot-mike which allows instant communication between rider and passenger, this is a priority for me. Does this, or any BT system, allow for instant communication or does the VOX have a delayed activation? If listening to music with the device is there a delay with the VOX? Thanks.
A shopper on Dec 19, 2013
BEST ANSWER: I had the same worry. Thought it might only allow one person to talk at a time... NO that I have it I can say no delay at all with the intercom. Up to 4 people can talk at once in HD audio or up to 8 people in SD audio.
Can this unit be installed in a Shoei Neotec helmet?
Walter B on Mar 15, 2016
BEST ANSWER: The modular component of that helmet may necessitate the need for using the boom-style mic vs the flat mic. Otherwise I don't see why the earpieces and the devise itself would be a problem to install on the part of the helmet that does not lift upward.
The universal intercom is the biggest selling point for me as Most of my friends have Scalla intercomscan Can I conect all five chanels to Scalla intercoms at is there a limit to interconectability? I read on a form that in order to conect to another brand that you have to rout it through your phone somehow.
A shopper on Apr 20, 2014
BEST ANSWER: From what I saw on the manual, you can only pair one non sena device to one sena device, you can start a 4 way intercom with 2 sena's and 2 different intercoms
