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

I bought a helmet first, and then picked these speakers out to go into the helmet. These are exactly what I wanted, and work great.Only problem I had was that these speakers don't say which one is the right, and which one is the left. So I just made two audio tracks, one that was right only, and one that was left only, and then I played those tracks through the speakers, to make sure I knew for sure which speaker was the right, and which speaker was the left. Then when I knew, I slipped them into the helmet, and it works great.NOTE: One speaker has a short cord while the other speaker has a long cord. The short cord goes to the RIGHT SPEAKER, and the long cord goes to the LEFT SPEAKER.If you have a small player like I do, you can fit the player inside the helmet, or run the cord outside the helmet if you want to have quick access to the player. The reason why I decided to go with a cord instead of Bluetooth, is because Bluetooth can easily lose signal. If you don't want to lose signal, cord is best.

Note*******I was using these speakers on a sena 20s unit, yoyr experience may vary if using a different device*****Sound not comparable to the sena HD headset speakers for the about the same priceIf using a sena 20s skip these...

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.

I bought these for my AGV K5S full-face helmet; I got tired of wrestling with corded earbuds every time I put the helmet on. The sound quality and volume of these speakers is pretty impressive when manually held against the ear canals prior to mounting, as specified in the manual. Duplicating that when they are mounted is a challenge; on my K5S, the helmet strap mounting rivets prevent positioning the speakers just that TINY bit more forward for best results (for me), but still, pretty nice sound. This, of course will vary from user to user.My biggest gripe is, the self-adhesive Velcro mounting rings come pre-attached (velcro'd? Is that a word?) to each other. These are by necessity, pretty thin, and in separating them, they are easily deformed/damaged/torn. Not cool. Additionally, the Velcro does its job almost too well - when trying to remove the speakers, the adhesive lets go MUCH easier than the Velcro. It would also be nice if there was some means of securing the connector to the helmet included (i.e. an adhesive zip-tie mount). They're inexpensive enough, and for the price of these speakers, should be part of what's "in the package".Interestingly, there are two sets of spacers included, which if used, would suggest that the helmet is too large for the wearer; a motorcycle helmet should fit snugly, with almost zero free play and no movement when the wearer shakes his/her head side to side. The standard mounting rings position the speakers right up against my ears; any closer would be uncomfortable over time.I'm going on my first lengthy ride (>150 miles) in a few days, and will update this review if I discover any glaring problems or pleasant surprises.
