Sena 20S EVO Bluetooth Headset System, Dual Pack

I got this to replace an older SMS 5 that I couldn’t keep paired with a newer GPS. I’ve got two other 20S EVO models that I and my wife use on a couple of other helmets. Overall I was quite satisfied with the performance of those so … . Installation was fairly easy and the unit fits well in my Scorpion helmet. Performance is as good or better as my older units. I only have 2 complaints. (1). The “Quick Start Guide” is a joke. All it tells a new user is how to turn on/off the unit. That’s it! Really, Sena? No information as to how to pair it to a phone or another unit? NOPE. Gotta download the “Full version or User Guide from their web site or the Sena Utility App. Pathetic and lazy. (2) When I tried to register the unit with Sena I never could find a model number that their website would accept. The instructions say it’s on the box but I put every number I could find on the box in there to no avail. Guess that’s one way to avoid having to deal with warranty issues.

Great job

I have had the smh-10’s for 10 years. They were awesome and proved the worth of Bluetooth headsets to me. So I decided to upgrade and see if a little more premium was worth it. I bought the duo set as we use the intercom a lot.
Pros: Intercom wind noise is much improved over the 10’s. The upgrade speakers have a much fuller sound than the old ones. It still won’t wow an audiophile. But it is good sound. Speaker placement is everything. Battery life is awesome. They charge quick. Mounting is easy. I use on a Bell Pitboss. Wife has a Harley half helmet. Controls aren’t all together simple. Most basic functions come pretty naturally. The app helps with some more complex stuff vs. going through a sequence to do it thru button pushes and such. But once set up, it’s mainly volume adjust and intercom on/off, or answer phone call. Volume is separate for each mode.
Cons: The only one I can think of is, voice command while riding is not very effective. It’s like all the noise filtering is turned off when you try to talk to Siri, and she doesn’t hear too well. I haven’t figured out how to keep it from switching to the bike when I answer call or make one. It’s usually about a second after they answer it swiches and I have hurry and switch it back. May be more of a Harley thing than Sena

Great to communicating while on snow machine. Do not have the range that I expected but ok.

I was super disappointed with this (very expensive) set of communicators. The first thing I noticed was that the main unit attaches very loosely to the helmet clamp. It literally rattles loosely on the clamp, and when it does, the headphones loose connection and operate intermittently. Both of mine did this and I see other reviewers had this problem, as well. I had to hold the main unit tightly to the helmet clamp to get any sound.

The next issue seemed to be a malfunctioning bluetooth transmitter. When I went into phone pairing mode, the 20S responded as expected and flashed the lights it was supposed to, but no phone in my household was able to detect a bluetooth signal to pair with. When I attempted to pair the intercom function, all I could get from either device was “Intercom Failed”.

I did try to troubleshoot them, and I followed the manufacturer’s instructions to perform a hard reset, but it didn’t help. Frankly, if I have to troubleshoot a brand new device, that’s a big red flag to begin with.

So they are going back to Sena and I will look for something that actually works out of the box.

We replaced our old one with this and we were very pleased. The connectivity was a little hard to figure out but once we did it was a breeze. The size is perfect, not too big and not too little. The sound quality is really good. We have been on several long trips and haven’t had to charge the battery at all while riding. These are a good quality and perform to their name.
