Sena 20 S Bluetooth Headset

The 20S Motorcycle Bluetooth Communication System is the latest communication device from Bluetooth leader Sena. The Sena 20S features a staggering 1.5 mile range, advanced Bluetooth 4.1 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 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 4.1 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.

Great sound, quality of product Very easy to install and use. You need to ride with it a couple times and you'll realize, its amazing. I used earbuds and speakers and they both sound great! Well worth the money! July 19, 2016
Excellent device for the money...needs improvement in one area... This is a remarkable device for the money. It has a lot of capability, some of which I have not yet tapped. The sound quality of phone calls is excellent, even at speed on the bike. Note that I am wearing a modular helmet and am behind a fairing, but even with the helmet chin bar raised the call is clear. The one quibble I have is the music audio quality through the speakers. I generally wear ear buds plugged into the Sena, so this is not a big issue for me. But, music played through the helmet speakers is harsh and lacks bass. This may be ameliorated by using the foam spacers to bring the speakers closer to your ears, but even with the intermediate spacers that I used, the music sound quality is poor. I would not be happy with it if it didnt have the capability to plug in ear buds. Perhaps Sena could produce a higher quality speaker and offer it as an option.Overall, It's a very good product - clearly a lot of thought went into designing it. July 19, 2016
Great Device This is my second helmet Bluetooth device. It is a really well thought of and built device. Works like it should. The helmet that I put it in for my personal use had speaker cutouts and wire routing slots that made the install a really nice experience. Tried it on a friend's helmet which didn't have the cutouts and it wasn't that simple, but with patience and a little massaging it could have worked for him as well. The usability of it depends on how well you become familiar with the equipment before you begin your ride. They have a great app for the device that comes in handy on the road when you forget how to do something. The speakers aren't the greatest in my opinion, absolutely no bass. For the money, it is in the higher price point than a lot of other units, but in the end, like most things, you get what you pay for. I feel that this unit will be around for a very long time. The quality to me was the biggest selling point and so far, very worth it. July 19, 2016
Fantastic device. Clear audio but setup with multiple headsets is involved. I had a Scala Rider G9x and could never get it to function as advertised. I had problems getting multiple bluetooth sources working in conjunction. I had to constantly manually switch between sources to hear music or GPS instructions or have an intercom conversation. Then I replaced the G9x with the Sena 20s and its a dream come true. Audio quality coming from the Scala to the Sena is like going from analog phone lines to a digital cell phone conversation. The audio is clear and almost like someone is living inside your helmet if you use a supplied windsock and turn off Sidetone! The audio multitasking is fantastic compared to the Scala Rider. I have tried the GPS Nav apps on my phone along with music players and the intercom going. Sometimes the 20s doesn't return the music to the proper volume but the next time the intercom kicks in it will usually put the volume back to the proper level. With the Navigation App option turned on in the Android App the Sena will duck all other volumes on say a 1 out of 10 scale so you can hear your voice directions. This also works with an external GPS device connected through bluetooth. Setup isn't easy but once you get the hang of it it isn't bad. Use the App! If you have multiple headsets you are going to want to pair each headset with its own phone and use the Sena app on each to configure. When you pair headsets the priority is Last in First out. So the first headset you pair will be the lowest priority in your pairing list. The last will be the highest. You will want to name each headset something useful. (Not just Sena1, or Sena2) Use peoples names or your name and "passenger" for the others. It's easier to keep straight. When you pair the headsets turn off any other headsets other than the two you are pairing. It will make your life easier. Opening intercom channels is easy peasy. Just tap the center silver button once for channel 1, 2 for 2, 3 for 3. The fourth channel and up requires you to hit the button 4 times, then rotate the dial to select the headset from 4-8, if you have that many paired, then hit the silver button again to select and open the channel. I have audio profiles set up for each volume on my phone so phone volume stays the same, music volume is set properly, and navigation sound is set. They are all level in my Sena once it finally gets to my ears. The firmware update process is fairly simple, the button layout on the application is kind of garbage, but you get used to it. You have to use a PC to update the firmware. The phone button opens "OK Google" so as long as I'm below 60mph I can do any kind of voice commands on my phone as well as the Sena voice prompts. Pro-tip: I had some wind noise at sustained 70+mph speeds. If you have that problem move the clamp towards the rear of your helmet out of the windstream and see if that helps! I would also turn off the Sidetone functionality. On a multiple headset intercom call the wind noise gets amplified and you can't hear anyone talking. Even with just one headset using Sidetone audio quality is severely degraded. July 14, 2016
Mixed emotions I've struggled with bluetooth devices for over a year. This model, along with the newest firmware, soon to work pretty well. I still struggle to balance the sound levels; the ringer, intercom and cellular voice levels all seem to adjust differently and take some work to get balanced. The audio multitasking is poor. I can't hear the music when on the intercom. The main reason I got this unit... the music is very choppy, even with the antenna extended. I end up turning the music off because the constant cut in and cut out is so annoying. Kind of defeats the purpose of buying the 20 model, yes? There is a new system to hold the microphone more solidly, and that is good. There are still wires coming out the front and back of the mount, and that is not good. The mic wire is tiny, and not protected well. July 12, 2016
Great ideas and usage Sound quality is poor for music. Clarity of sound is good for talking(phone and such)but lacks bass and mid range. reception is good for even FM. Instructions are horrible! If you are over 40 the tech is a maze to get through. Installation is very easy.Over all It's the best out there. I would still recommend it until new tech surpasses it. I have ridden mostly Harleys over the last 40 years and just switched to an MV Agusta 800 Brutale Dragster RR. The evolution of biking has brought us great new tech and this is cool part of it. I'm 61 and still loving it. July 5, 2016
sleek and easy to install I would recommend this product to anyone that is looking for a Bluetooth com device and double as a Bluetooth media device for a helmet. The only complaint is that the speakers are a little bulky and sometimes makes it uncomfortable to wear because they dig into the ears. That and i cant find anywhere on the Internet to see where the recommended placement of the speakers are.But it has no problem connecting to my Android based phone, Bluetooth calling and music is great. I have not had a chance to use the coms on this unit due to nobody having coms that i ride with. July 5, 2016
Bit of a learning curve but a good product I bought two of the Sena 20S units for my wife and myself and they have worked a treat. I really only have two things to find faults with. The first is the learning curve. It take a while to learn whether to press one button for one second or to double tap i, when to rotate the wheel for which function, how long to hold down the buttons and wheel (up to 12 seconds for certain commands) and so on. The second thing is that it is way to easy to accidentally spin the wheel and end up either not hearing something or getting your ears blasted. The Voice recognition is a good feature but at software level 1.6.1 it still is more than a little flaky and only sometimes understands a command. Also, whacking myself on the side of the head twice to activate it is a bit annoying. On the other hand, when the 20S is pared with an iPhone, Siri never misses. I have been told by people I am talking to that the noise cancellation on the mic is great and that they had no idea I was on my bike. I have it mounted in a LS2 Vector which isn't a particularly quiet helmet but I can still hear spoken voices perfectly well. Not much use for music, though, but that's a function of the helmet rather than the headset. I have never had problems with it pairing with multiple devices (phone, gps, passenger, other bikes, remote) although I have never tested it to it's full advertised range. So, other than having to memorize a set of command more complicated than a DVR, it's works great. July 1, 2016
