I A S U S High Def XSound 4 Helmet Speakers - Motorcycle Snowboard Helmet Speakers - Works with Most Comms with Earbud Ports – Includes Accessories for Install

The High Def XSound 4 Helmet Speakers absolutely deserve 5 stars. The build quality is outstanding — solid, durable, and clearly made to last. But what really blew me away is the sound quality. Compared to the upgraded JBL speakers I had for my Cardo, the difference is like night and day. Whether it’s music or phone calls, everything comes through crystal clear, even at highway speeds. I haven’t had a single situation so far where I couldn’t hear clearly, which is a game-changer for longer rides. If you’re serious about audio on the road, I highly, highly recommend these. Worth every penny.

These are the best helmet speakers on the market and I had the 2.1 and 3.1 Iasus Before this. Get yourself a amplifier or a FIIO M21 and enjoy the bass and sound quality. These make the last 3 gen look like a C grade. These are the final solutions we have been dreaming for. Thank you IASUS for making these. No not use Cardo or any other brand. These are the gems. Do expect these to be amazing off some bluetooth device. These need an amp to shine.

I use these in my motorcycle helmet. Given that my review may not be relevant to others. For me to hear over the exhaust I need these at max volume and even with the bass low they crackle. It’s unfortunate because I thought with the money spent they would work great. With the volume down and my bike off they sound great but that doesn’t really help while riding.

Pretty good speakers. They have a very wide frequency range and by far sound the best of all helmet speakers I've tried. However, The ear seals do require great care and attention when you put your helmet on to ensure they stay in place as well as seal around your ears correctly. The ear seals are very soft and thin material. I can't see it standing up to more than 1 season of sweat. Taking your helmet off also requires great care not to rip the speakers out. I was hoping they'd be much louder. Even with a tight seal, I don't think they'd be all that loud when driving at highway speeds. So I've also ordered and external headphone amp to help boost the volume. EDIT: Picked up a headphone amplifier, These speakers take the high power input like a CHAMP !!! I can feel the speakers puffing air on my ears when the bass goes, and they stay super clear !!! My helmet now actually has the volume needed for highway riding. Only Wish it didn't require upgrading the source to the speakers to do it. Would be amazing if these speakers came with an inline amp.

These are staggeringly good. Loud and clear but balanced musically. I paired these with the small inline amp Iasus also offers and can say I finally have what I have been searching for. I will be buying another set for my wife immediately.
