New EAR3H-MK2 Helmet Amplifier—a refined evolution in helmet audio technology. We’ve meticulously crafted the EAR3H-MK2 to be smaller, sleeker, and more minimal, while delivering powerful digital amplification for an unparalleled listening experience.

Review: I have been using these amplifiers for a couple of years on my motorcycle with a Cardo intercom. They enhance every part of the experience. I'm sold on these units. I can listen to music at freeway speeds and enjoy it. I highly recommend them for motorcycles. Great product. It's small and does the job. The battery usually last all day. I keep the charging cable on the bike so I can recharge it if I'm doing a multi day ride.

*by M***N on 12 February 2026*

This tiny amp sounds great and completely solved my problem of hearing my fellow riders on Cardo with my foam earplugs in. I can turn the guys up to hear them clearly (not blasting). The battery lasts all day for me. Changing the volume boost underway is fiddly with gloves on. You should experiment with it on your own so you don't have to play with it on the go. The magnet mount actually works. I thought surely the unit would be coming off all the time, but after a thousand or so miles with mighty crosswinds, and some "track only" speeds, it has done fine.
