Sound Signature: clear, full range response with enhanced bass

Drivers: 3 balanced armatures: 2 lows, 1 high with single crossover

Custom in-ear monitors designed for those who like the punch of a little extra bass. Flexible soft silicone earpieces deliver long-wearing comfort and perfect fit for maximum isolation and a secure seal. 3MAX delivers clear, full-range response with a seductively enhanced low end.

"For me, both bass clarity and vocal clarity are very important, and the 3max gives me both.

“They’re very balanced, and the mid-register is great. And the isolation from the soft silicone means I don’t have to turn up my volume as much. With my old system, after a two-hour show, my ears would be ringing. Now, when I take my monitors out, my ears aren’t ringing and I don’t feel as fatigued. It’s a blessing.”
