IASUS EAR3H-MK2 Helmet Audio Amplifier 12dB Volume Boost - 3.5mm Input and Output - Compatible with Most Helmet Comms Systems with Headphone Earbud Port

Produto de excelente qualidade

This amplifier with the Xsound 4 speakers are the only way to go for the best sound possible in a motorcycle helmet. Took me a bit to route the cables in a way that work well for my helmet, but it works very well. Very happy with it. Blows JBL helmet speakers away with this combo. The magnet used to hold the amp on the helmet is super weak. Be prepared to need a better magnet. Still worth the purchase, but would be nice if it came with a stronger magnet. Above 75mph on the back of my helmet, it blows off.

The amp works great in-line between our Sena 20S and Iasus speakers. I bought a charger and cable system separately. Iasus should provide a proper charging solution with this amp. Also, the provided magnets are useless. I mounted with 3M tape.

You pair this with their xsound 4 and buy aftermarket 45mm headphone earpads and the sound is ridiculous!!!!

Package was obviously a return. Seals on the package were intentionally cut and half removed. Amplifier is defective, hisses crackles and makes the headphones sound worse than without ban amplifier. Terrible ethics, I wouldn't expect this type of business practice from a manufacturer. Really disappointing Iasus.
