Customer Testimonial

Compact and powerful, the EAR3 Micro Amp clips good onto my jacket. Never fell off. The transparency mode is genius for city riding.

I love how the EAR3. I use it for jogging or cycling, it delivers the boost in audio quality not only the volume. A must have for anyone on the move.

Never knew what I was missing until I tried the EAR3 first gen. Got the MK2 because that one finally died after a good 3 years. The sound clarity is outstanding, and mixing in environmental sounds keeps me alert on busy streets.
