InEarz pro audio monitors deliver unmatched comfort and sound at an affordable price, and are made in the USA. InEarz' parent company, Persona Medical, has been making custom in ear products for over 50 years. They use that knowledge and experience to build perfect fitting in ear monitors, both custom and universal fit. InEarz Audio is also the only product line offering the safety and clarity of ADEL Technology. The ADEL Technology acts as a pneumatic shock absorber, taking the pressure off your eardrum. The benefits include higher perceived volume at lower actual volume by eliminating the stapedius reflex, higher clarity and increased spaciousness due to improved sensitivity of the eardrum, and safer listening for longer periods with reduced ear fatigue.
