Sena 20 S Bluetooth Headset With Slim Speakers

The 20S Motorcycle Bluetooth Communication System with Slim Speakers combines the best of the Sena 20S Headset with slimmer speakers. The 20S Slim Speakers fit even better into helmets that provide smaller speaker pockets. The slim speaker measurements are 32mm diameter, 7mm thickness, with an output of 20m Watts. 

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.

Quirky software, not waterproof, short range.
The software can be finicky. You have to know the official methods and controls, and then you also have to learn what actually works well. Getting a group paired is about half following directions and half blind luck / button mashing. If someone goes out of range you are likely to be fiddling with it again. This happens more often than you would think since the range specifications are actually lies. It has maybe a quarter mile range at most.
FM radio only picks up certain stations and its not a range issue. I can't pick up the local rock station with an antenna a few miles away. Also does not work well in rain. It isn't water proof so water gets in and starts making it act up. I imagine with multiple exposures over time the contacts inside will corrode and I'll have an expensive paper weight.

On the up side, the battery lasts a really long time and the aux port lets you use some real speakers instead of the garbage it comes with. Just be careful not to blow them up. I'm on my second set of modified over the ear headphone speakers.

Very Disappointed.
While riding with 5 other Sena units we couldn't get more than 3 units paired. The fourth attempt would pair but bump the first pairing off the group. Clarity was good for about 300 feet but was lost or badly garbled after 600 feet ( even though the unit was in sight). User friendly it's not. You need to watch the YouTube videos to understand the quick reference sheets. One of the units lost the music whenever a conversation over rode it and the unit needed to be turned off and back on to listen again. We purchased because of the blue tooth phone capability, but in the mountains had no cell service. I'm going back to my GMRS set. It always works and has no limit on the number of users in the group.

The dimensions listed for the speakers is the same as the original 20s (36 X 6.5), so what are the real dimensions?
Gary T on Aug 7, 2016
is there a dual kit available with 2 sets of 20s slim units in the box?
A shopper on Nov 10, 2016
So you can have open comms?
A shopper on Feb 28, 2017
BEST ANSWER: Yes. When paired with another device, the intercom link is always open. Unlike a CB, you do not have to push a button transmit. Just talk. This unit can bring up to 8 others in on the conversation.
Is there anyway to talk to your passenger with out buying 2 units? Maybe trough the aux or headphone jack? Also if doing it though one of those would it cut down the functionality of the device?
