HELYES Ambient System
Don't get isolated from your fans! HELYES (stands for Hear Everything Live) is the World's first in ear monitor that doesn't rely on a pack to control it. The HELYES (Hear Everything Live) system is an ambient system which works totally independent of your monitor mix. The microphone handles up to 140 decibels without any audible distortion.
A push button for changeable volume settings and a on/off switch make it easy to control your sound environment.
The rechargeable batteries ensure up to 8 hours of use. Even if you forget to recharge the batteries, the in ear monitor will work as usual.
