Sena 20 S Bluetooth Headset Dual Pack

The Sena 20S Motorcycle Bluetooth Communication System is the latest communication device from Bluetooth leaders, Sena. The Sena 20S features a staggering 1.5 mile range, advanced Bluetooth 4.0 and a built-in FM radio tuner. Stay in contact by calling hands-free on your Bluetooth phone, rock out to your favorite riding jams in stereo or listen to voice instructions of GPS navigators by Bluetooth wirelessly, all the while having conversations in full duplex with a passenger or other motorcycle riders.

The 20S is a state-­of-­the-­art motorcycle and powersports Bluetooth communication system. The unit provides a sleek and aerodynamic design that offers a versatile jog dial that maximizes the ease of use for riders.

The Sena 20S features several industry firsts for the motorcycle Bluetooth communication headset market. Bluetooth 4.0 technology with dual Bluetooth communication modules increases the performance and reliability of the headset while also allowing for increased high definition audio quality. The advanced Audio Multitasking allows for a seamless blend of incoming and outgoing audio to create a mixed audio experience versus the traditional interruption based audio technology of other Bluetooth devices. The audio multitasking function creates the most close-to-natural audio sound while running multiple audio functions simultaneously and intelligently.

With the 20S, users can call hands­free with their Bluetooth mobile phone, listen to stereo music or voice instructions of GPS navigation by Bluetooth wirelessly, and have intercom conversations in full duplex with a passenger or other riders.

Sena 20S Bluetooth Headset - Dual Pack 4.1 5 63 63
Warranty required My wife had been commenting on spotty connections on the hard-wired J&M units in our Arai RX-Qs wired into the Goldwing system. She also didn't like having to listen to music at the volume I would choose. Bought the dual pack but had one unit that would start buzzing loudly after listening to music for about two minutes. Tried it with the other set of speakers and helmet mount that was not installed in a helmet. Same results, so unpaired from my phone and paired to my wife's phone with same results. Sena sent complete new single unit set. Very little testing so far, but both are paired to phones and to each other for intercom. Look forward to trying all the features, even if it is sitting in the living room with the helmets on looking at snow outside. I hope to update this review with better ratings, but so far the only high point is the volume and quality of sound. March 2, 2015
20S I bought a set to be able to talk to my passengers and for use with a gopro. The clarity at which it picks up sounds is great, even running down the road at 60 MPH the person talking to me over the phone could hear me easily. The complaint would be the left speaker after three weeks of use is starting to have a cracking sound to it. February 21, 2015
Works best for Helmet to Helmet Communications One unit is very sensitive to wind, often prompting me to "say a command", then not recognizing the command, prompting me three times before cancelling itself. The Helmet clamps on both units failed early on. The spring mechanism that locks the unit to the clamp became in operable. One unit is "stuck" on the clamp, the other unit will not lock in place, causing inconsistent contact between the clamp and the unit. I did get a RMA # from Sena and sent both units back for replacement. The support from Sena to date has been very good. I hope the replacement units function better. Phone conversations are challenging. The caller on the other end often has trouble understanding me. I ride a Goldwing with a good size wind screen and a full face helmet, but still for what ever reason the caller has trouble hearing me clearly. The rider to rider communication if very good, very clear for both riders. Pairing was easy. Tapping in and out of conversations is easy and convenient. I only use my unit with one other rider, as such I haven't found much use for the Sena App. February 18, 2015
Outstanding I have had the Scala and one of them went bouncing down the road. Scala said "Sorry" we don't cover that, we don't repair them, nor do we offer you a discount on another one. I said OK, I'll go try Sena. I am ecstatic. It works so much easier and the sound clarity is tremendously better. Revzilla was easy to order from, great price, the shipping information was sent quickly and it arrived on time.. February 16, 2015
Much better than expected I was doubtful at first due to all the forum discussions regarding poor build quality, but sena has really turned it around in the past couple of months. For the dual set i received, the speakers were fantastic. Sound clarity and bass are great up to 65 mph in my schuberth c3 pro. The large jog dial is easy to use. VOX are simple and easily recognized. FM reception is actually as good as my alpine car stereo ( I'm located in socal LA area). Installation on my c3 pro was actually really easy(with the sticky mount) despite some people saying it doesn't really fit. Noise cancellation is as good as all the other reviews claim. My roommate called me the first day I had this and thought i was calling him from an empty room. This unit has definitely changed my riding experience. Special shout out to Revzilla getting this to my door steps the day after i ordered it!! Awesome service as always! February 2, 2015
Changes the riding experience completely around I don't know why it took me this long to look into getting communicators. I guess I felt it was just hype. I won't talk about how great sounding this set is or how multifunctional this is... and it definitely is multifunctional. You can get that information from the tons of reviews on this site and others. I'll just speak of the install of this set on a helmet that does not have a lip that will fit the base clamp. I use a Nolan N44, this has a very thick base that would not accommodate the clamp. The Sena 20S will happily install via double-sided tape. So far, I haven't had any issues with this type of install. I'm glad this worked out because I knew the clamp would not fit. So grateful to Sena for including so many accessories with the unit. The different mics, car charger and extra foam pads are all welcome and appreciated. I look forward to using this as much as possible, even when not in a group ride, the FM radio functions are awesome. January 19, 2015
Great product Will recommend to others ! There products are top of the line . There tec . people are quit helpful January 5, 2015
Installation not very flexible Of three helmets we've tried, it has only installed easily on one. The others were more cumbersome. Clarity is good. Dial can hit the collar on your jacket and turn it off or volume down. December 28, 2014

Thomas C: Debated between Scala G9X and Sena 20 for months, and after vetting both products thoroughly chose the Sena for it's ability to multi task. I believe, based on other riders personal feedback and public information, both Scala and Sena's latest units have some significant challenges to overcome in design.

Kimberly O: Sena is top company for Bluetooth with customer satisfaction for performance (yes, I did my homework).
Battery Life is very important, sound, reliable and performance between two utmost important. The range
of 1.5 miles between radios is great. Also, software updates important along with UPS battery charging
important, too. This is their new flagship product that includes FM radio, too. MANY POSITIVES !!!

Weldon W W: Revzilla reviews on Sena products & 20S interoperability teaser Jan 5, 2014
Paul J: The Sena S10 on the web seemed to beat all the other competition in the high end Blue Tooth market except for the Cardo G9; where after exhaustive internet research it was a tie with the SMH10 having better sound and the G9 having a built in radio. With the new Sena adding a radio option and the jump to blue tooth 4.0 (4.0 adds multi-point intercom and extended bike to bike range) the choice was obvious. Dec 4, 2013
A shopper asked: How many units can be paired in full duplex? I ride with 4 others (5 in total) and interphone f5 xt is the only one to state it will do 6 riders in full duplex. Can sena 20s do 5 in full duplex?

Because these are new model, Sena pushed back the production date a couple of times. They are scheduled to ship in late June.

A shopper asked: Is the Sena water proof, if riding in the rain? Aug 11, 2014
Answer this · Send to friends Good question? Yes (0) No (0)
David M: It is not. Sena markets it as water resistant. I can't put a URL in this comment section, but go to their product page and you can see: "Water resistant for use in inclement weather". Not waterproof.

I used my SMH10 all day in the rain (behind a fairly substantial), and it has the same type of USB rubber cover and mounting system. I didn't have any problems. Searching the web, some folks have had trouble when really testing the water resistance.
Aug 12, 2014
Reply to David Good answer? Yes (0) No (0)
kevin r: It's supposed to be weather protected, and wouldn't be very useful if not. There are rubber covers over power & aux inputs; just have to remember to keep the covers tightly sealed after charging. So far, it hasn't rained hard enough this summer to know for certain sure. But I'll be riding with it in the rain and hope it is! Aug 11, 2014
Reply to kevin Good answer? Yes (0) No (0)
Nathan B: The Sena 20S is weatherproof per Sena; meaning it can withstand dust and rain drops but not a full submerging under water. I have personally rode in heavy rain for over 2 hours and steady rain for 8 hours with my Sena unit attached to my helmet without any issue. Is it waterproof? Subjective. Aug 11, 2014
Reply to Nathan Good answer? Yes (0) No (0)
Greg B: We rode in the rain going to Sturgis South Dakota. Never had a problem. Can't say I would put it in a tub of water,but it did well in the rain showers we got caught in . To be honest I never thought about it,it worked well rain or shine. Aug 12, 2014
Reply to Greg Good answer? Yes (0) No (0)
Alexander W: The manual (page 60) says to keep the product dry and away from water. It may damage the product.
I haven't exposed the 20S to any rain - based on that statement in the manual, I plan on keeping it dry.
Hope this helps...

Answer this · Send to friends Good question? Yes (0) No (0)
A s: I don't have any experience with the f5mc but I've been using the 20s for about 5 months. I've had generally a good experience - my riding buddy has the sena 10 and we connect easily and seamlessly. i bought a 2pack and put one in my girlfriends helmet. I can use the intercom, share music and use my nav program all at once, although the nav voice prompts can get drowned out by the other two at times. I believe sena addressed that in the latest upgrade but I haven't used it this month.

I've had some trouble at times with connections that fail - but I've found a quick reboot sets it right.

As far as performance - I've been on the telephone on the highway at 65 or higher and the person on the other end of the phone has no idea I'm calling from my bike.

I'm happy with the sena 20 - just bought 2 more as Christmas gifts.

Yeshe P: Another feature that might be a selling point for the 20s is the jogdial and voice command feature. You can tap the unit and issue voice commands like launch apps/play music, play fm radio, speed dial, etc. The jogdial is easy to use especially if you have gloves on.

Also, with my android phone I can use the app to program the unit and add things like speed dial, FM radio stations, update the firmware, access the reference manual, etc.

Yeshe P: I purchased the 20s dual pack to share with a buddy, and another clamp kit for my other helmet. It works great, no complaints.

I don't have experience with the F5MC, but spec wise, the key differences would probably be the Bluetooth version (low power usage capability in BT v.4) and weather resistance of the unit

20s, bluetooth 4.0, 'weather resistant'
F5MC, bluetooth 3.0, IP67 rating which is more rugged.

Newton P: Hi Mac,
I have been using the dual Sena 20s since May and have been very happy with it. I normally do not ride with others, therefore I have no experience with the group intercom. However, my wife and I are having a blast when we ride together 2 up. The duplex mode really works very well. Both of us listen to our own music, talk among ourselves and have our phones also connected. On top of everything I stil have the GPS paired and working very well. Some friends have the Interphone and I can't compare as they can't have the same amount of pairings like the Sena does. The Sena is the only one that will allow you to have 3 devices (phone, gps and bike) plus the intercom. Besides the Sena customer service is second to none. I would go with the Sena.

Robin J: I have the Sena 20 dual pack. I have been very impressed with it overall. I paired it to my Iphone and the clarity is amazing. My one complaint is that I have been unable to pair it to my Ipod as a secondary device. Fairly easy to operate. The radio portion does not have great signal pick up capabilities. It is an excellent communication device though I feel the distances or bike to bike communication are exaggerated. Dec 10, 2014

I am in Gatlinburg TN this weekend as I write this and the wife and I used them for the last 2 days and really are impressed.

Gregorio B: The mechanism is called music sharing, and it is built in the sena 20s. Once you have paired the second headset, and once you establish a two-way intercom, you can share the music by pressing the jog dial until it beeps three times. Read page 29 on the user manual if you have doubts.;-) Jul 29, 2014

A shopper asked: Can I use this on a 3/4 helmet? Feb 23, 2015
Answer this · Send to friends Good question? Yes (0) No (0)
Kim C: The mounting hardware is universal. On a 3/4 helmet , the issue you will have is wind noise from the mic during intercom sessions. The intercom function is easily switched on and off with a push of the dial on the side of the unit so you won't have to listen to the wind all the time. One negative is that the intercom is not voice activated; when it's on it's on, ergo the wind noise unless you switch it off. This will not disable the Bluetooth music streaming.

I highly recommend this unit. I am still learning many of the available functions.

Kim C: The mounting system is pretty universal. It is basically a clamp device with foam padding that squeezes the helmet shell. There is plenty of slack for a variety of thicknesses.

I mounted mine to two HJC modular Symax III type helmets with no issues.

Works great! I highly recommend this unit.

A shopper asked: How does the Sena 20S work with Snowmobile Helmets? Will it still clamp on - ok? Not sure how motorcycle helmets compare.
How does it handle in the extreme cold? Thank you!
Oct 31, 2014
Answer this · Send to friends Good question? Yes (0) No (0)
Sandro R: I've never seen a snowmobile helmet. It depends on how you can separate the liner from the outer shell, and even then, you can just glue it to the outside shell if you prefer (it comes with double sided taped for that). I have the same motorcycle helmet as this guy, AGV Corsa, he didn't want to shove the clamp in between the shell and the innermost liner (it's hard), but it's doable. The innermost liner in most cases is just softly glued for finish purposes, I believe, so no big deal shoving the thin clamp part to it. Nov 16, 2014
Reply to Sandro Good answer? Yes (0) No (0)
Rob L: I'm sure you won't have a problem clamping to a snowmobile helmet. The attachment is quite secure when it is put on and the quality construction should hold up well in extreme temperatures. The controls work well when wearing gloves as well.

I hope this helps

Weldon W W: Reading the questions/answers on the Sena Technologies Help Desk, after having a search 4 "waterproof", I would venture the unit is water resistant. If it's raining hard, I'd find some shelter. In a lighter rain, My guess the water would blow off due 2 wind. Unit is 2 new 4 a lot of feedback.

Marc R: I am pretty sure that there are additional mounting brackets for easy change helmet to helmet. I also asked about half helmet usage and a well informed CSR recommended the Sena SMH 10 for half helmets. The units are already in ear pieces that attach to your half helmet and sync with many other communicators. I am in the same boat and will likely get both so I can have the freedom of helmet usage.

Marc R: Oops! Update...as Hung mentioned above, the Sena SPH10 or 10FM is the better choice for half helmets. I will likely get both unless I can find a creative way to mount the 20S. I believe it can be done with earbuds or the ear cover inserts for half helmets if the mic Boom is mounted to the earflap like on the SPH10. Could be fun but I don't want to ruin it...too spendy for that! Lol. Jun 6, 2014

A shopper asked: Does this product attach easily to a half helmet or will I have to purchase some sort of add-on? May 3, 2014
Answer this · Send to friends Good question? Yes (0) No (0)
Hung W: The 20S is just like Sena's SMH10. It can be mounted on most helmets in under a minute. Some helmets (like Nolan's N104 modular helmet) require modification to the plastic mold of the neck roll in order to allow the clamp to work. Some users use industrial strength outdoor rated double-sided foam tape (from 3M and the like) to mount the headset rather than modifying their helmet.

If your helmet doesn't cover your ears, then neither the SMH10 or 20S would readily work for you. These systems are designed to go into full face or modular helmets where the speakers can be tucked behind the liner. What you will need is something like the Sena SPH10H (or SPH10H-FM with built in FM tuner) Bluetooth Intercom For Half Helmets. They are available here on RevZilla.

"The 20S audio system is redesigned for high-definition (HD) quality audio that provides crystal clear, natural sound quality, and is integrated with an audio booster providing sufficient sound level for noisy environments."

Hung W: The 20S is essentially an update to Sena's very popular SMH10. It will have all the functionality of that older unit, plus enhanced features. The SMH10 manual is available as a free download from Sena's website (the 20S manual is not yet available).

The first feature you are talking about is called VOX (for Voice activiation), and is standard on most motorcycle headsets (including the SMH10 & the new 20S). Yes, the 20S will permit handsfree (no button pushing) communication between paired headsets in intercom mode. The second feature you are talking about is called Duplex (simplex would be send or receive, duplex is simultaneous send and receive). The 20S will allow up to 8 headsets to be paired in full duplex, as well as having extended range compared to the SMH10.
