High Performance Helmet Speaker Headphones with a 3.5mm Earbud Audio Jack Compatible with Most Helmet Comm Systems - The XSound 2.1 R fits in Most Ski, Snowboard and Motorcycle Helmets

Replaced my Sena 20s speakers with those. I even did a frequency comparison between the two speaker sets within and outside the helmet. The sound quality is superior with those speakers.Surprisingly, while the Sena 20s speakers were louder outside the helmet compared to these speakers, the quality of the sound was so much better with those new speakers.Taking them out on the slingshot revealed their true quality. At 50 mph the Sena 20s speakers made speaking/understanding really hard not to mention music quality was really bad and anything above 50 mph was not viable.With those speakers there were almost no issues until 80 mph or more, which is to be expected that at some point due to the speed.In addition all the padding options and self adhesive padding raising the speakers to your ear also made a big difference but to be fair to the Sena 20s speakers, I also compared those after raising them and the same results as outlined above.What can you expect if you pay ~$600 for a Bluetooth set where the speakers are worth $39, which is the price you can buy those from the Sena website. They should really invest in better speakers or at least offer an option for better speakers.The install was easy with my helmets and you only need a very small philips screw driver to remove the old Sena 20s speakers and then plug in these speakers into the 3.5mm slot (there are 2 slots, one on each side but only one is the 3.5mm).My only issue is the power up of the Sena 20s system as it always starts at the lowest volume if you use the 3.5mm speaker output vs their proprietary speaker connector. You have to get used to that and I will contact Sena to hopefully come out with a new firmware to address this.The only reason for the 4 star on value is the price. Yes, those speakers are better but I think that price is a little bit too high.I am very happy with them and I can recommend them to anybody. I should mention that I do not use any amplifier as some people are recommending and I am very pleased. You don't need to blow your ears out and you have to be able to listen to your surroundings while operating any vehicle. Not to mention having seen pictures of people having glued their amp to their helmets and it looks hideous.

I got these for my Sena 20s.The upside: BIG improvement over the stock Sena speakers. You can hear actual bass sounds and the highs are not tinny. And because they are physically bigger than the stock speakers, ear placement does not seem as critical. I can stick a finger in my helmet and move them around a bit with not much of a change in sound. The stock speaker sound would change much more when I tried that with them.The downside: Well, besides the cost, there is a noticeable loss of FM radio signal strength. I can still get all 10 of my preset stations, but now I get station fade as I walk around and/or turn my head. The speaker wires ARE the antenna, and the right side speaker cable is maybe 2-3" inches shorter than the Sena one, so that must be it, because the wires are routed through my helmet exactly like the Sena wires. Now, they do include about a 2' extension cable with the speakers, so I inserted that between the plug and the Sena and it improved the reception, but the extension is way too long to try to fit it all inside the helmet. I suppose you could if you are really determined, but that's up to you. That's a lot of wiring to be running all over the inside of your helmet.Update: I managed to add the extension cable to my helmet wiring and while it did improve the reception, it's still not like it was with the Sena wiring, so these speaker wires must somehow be different. Maybe they are shielded.So, the end result is great sound at the expense of some FM radio reception. Of course, out on the highway away from cities you will have that anyway, just like in a car. If only they had made the wires a bit longer. It could also be the type of wiring making a difference. Maybe it's shielded or twisted, I don't know. I just know that the stock wires as well as my ear bud wires gave me great reception. No fade at all on any of my preset stations.I attempted to run the right side wire over the top of my head (a tip from Revzilla to improve reception) but it was a tight stretch with no slack at all, and would probably cause a wire break over time. What works best for my Arai full-face helmet is to run it along the lower chin where the rubber seal holds it nicely. It stays tucked in place without any stress or tight bends, and gives me enough slack to pull out the cheek pads without pulling on the wire.

Update 2: Customer service finally got in touch with me and required me to ship the headphones back on my dime so they could be "inspected" for warranty replacement. I never shipped them back and I won't be buying any more of their products. I wish you could do 0 stars.Update: The speaker wires shorted and now sound only comes out of one speaker. The 3.5mm plug and cable is designed so that when you mount a Sena 20S there is too much pressure and the cable is too short. A 1.5" longer cable would solve the problem. You could possibly try to extend the cable with an extension.Below 55mph these things sound fantastic. Theres not a huge amount of bass but they are much much less tinny than the speakers that come with either Sena or Scala Rider headsets. They provide a much fuller immersive sound without destroying the upper registry of hearing. Above 55 they are just OK. Not bad at all, but OK is all any helmet mounted speaker will be at that speed so don't take it as a negative. No helmet mounted speakers are going to provide bass that you can hear at highway speeds, physics won't allow it. These things are at least twice as thick as the Sena speakers and are much heavier. Keep this in mind because they will touch your ears. They come with a large amount of foam spacers and leather covers to keep them clean. I would not buy them again. Customer service has been non-responsive through Amazon. I'm currently waiting for reply contact through their website.
