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.

Terrible experience with no support Intermittently connects to bluetooth. Somedays it just won't connect to phone. When it does connect, there are frequent long pauses. There doesn't seem to be a fix and I have found the company (Sena) to be slow to help and their forums are useless. June 22, 2016
Great upgrade I have the original SMH10 bought in 2010, and only had to replace it because it's only lasting 5 hours. It was used a lot since I put on around 80K miles during that time. This one has even better features, far better sound, great battery life and just as easy to use. I highly recommend this product! June 21, 2016
Great features and ease of use. Easy to use the mobile app makes it easy to use all the functions and the range compared to the smh10 is great. Makes group rides a blast with your buddys takes the guess work out of navigation. So many great things about this bluetooth device. Highly recommend for any and all types of riding. June 21, 2016
Makes riding a lot more fun I have never had a bluetooth helmet setup before, and wanted to give one a shot. I installed in on my Shoei GT-Air before i rode with it. I use my iPhone for GPS, music and of course calls. The button on the back initiates SIRI immediately and allows for hands-free usage of the phone features. This past weekend, I used it with two other riders (one with a 20s, and another with a 10H) and we were able to hold conversations until we hit speeds in the upper 70s. The music clarity is great, and I continually get compliments on the clarity of the microphone for phone calls. I've been told that the clarity is better than the bluetooth setup in my new Audi! I do need to put spacers behind the speakers to move them closer to my ears- I'm having a volume issue as my speed increases. Also, SIRI can't tell what I'm saying when speeds approach 80 mph, but I can't blame the 20s for that. I'm amazed at how well it works, and how nice it is to ride listening to music, getting GPS directions and taking the occasional call. It's really a game changer. June 15, 2016
An amazing accessory Great product. You can speak with fellow riders with Bluetooth units. Listen to radio that comes standard with the unit. Listen to your own music from your phone. And the speakers are pretty clear. June 7, 2016
Awesome addition I love these things, especially with the v1.6 firmware update. There are so many features, it's hard to manage sometimes, but with the mobile app, you have questions and setting available everywhere. The v1.5 was glitchy when using the intercom and audio sharing, but an easy firmware update cleared that right up. I almost always ride with my wife or daughter and these are great for long rides. Sound is pretty clear, and I installed with the smaller pads so the speakers are closer to my ears. Males it a little tougher getting the helmet on and comfortable, but with the ambient feature, you don't have to remove it so often. The included speakers are clear and loud, but lacking on the low end. With a decent helmet, I rarely have my volume up past 60 percent, and I ride with no windshield. Short and simple, they work well. With a little tinkering, and the mobile app, installing is the toughest part. A must have if you ride in groups. June 5, 2016
with the Sena 20S Bluetooth Headset i want to were my helmet this headset is awesome makes riding even more enjoyable, sound quality is good doesn't have very much bass but music sounds great pairing is easy with the cell phone app. wen i receive phone calls people don't know i'm on my bike sound is clean no distortion. i love the large knob on the side easy to use with gloves. my favorite thing about it is hearing my navigation from my phone makes taking trips much less stressful. this is the first headset iv'e ever had and i'm glad i chose this one i'm very happy. install was easy just took me about an hour but it was my first time. sound great on my Schuberth C3 Pro.

Excellent product First off, I must say that I am quite surprised at the sound quality this little device puts out. I used to ride with in ear headphones which is a pain in the rear when one becomes displaced during a ride. This Sena has more than adequate volume and clarity to listen to music while riding. I've yet to use the intercom function but do use the phone function from time to time. I have an iPhone 6s and it pairs flawlessly with that and hitting the phone button on the Sena gets you to Siri. Since Siri can do pretty much anything with your phone you have near total hands free control. On the topic of call clarity I've talked to people at 75mph on a sport bike and they comment about how they had no idea I was on a bike until I tell them. listening to music really makes the miles click by, and when you want to focus just pause the music and do your thing. Overall I would give the Sena a top rating because it's such a powerful little device and makes riding so much more fun. May 31, 2016
