Reviews & Questions
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.
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 customization...an 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.
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.
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.
- 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. ***
- Voice activation works about 70%
- Radio sucks / worthless and radio sound quality is 'tin' sounding

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.
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.

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!
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!
