Sound Signature: studio reference, full-range response

Drivers: 2 balanced armatures: 1 high, 1 low with single crossover

Our classic custom in-ear monitors designed for clear, accurate, studio reference response. 2X-S has the same sound signature and drivers as our 2MAX, with the inherent safety of slightly lower sensitivity. Its flexible, soft silicone earpieces ensure long-wearing comfort and perfect fit with maximum isolation and secure seal.

"The sound quality is excellent, the isolation is great, and of course they are super comfortable.

"With the 2X-S, I can monitor at much lower levels and still hear everything perfectly, and they have held up great. It's pretty cool. This what keeps my hearing from getting worse, and I've got Sensaphonics to thank for it. If you want to do music as your career, be smart and respect your ears.”
