Cearvol Sell Sheet · Open-Ear
The open-ear athlete. A secure hook fit that never blocks the ear canal — full situational awareness plus clinical-grade compensation via the NAL-NL2 prescription formula. For the active early-stage patient who won’t wear anything that plugs their ears.
Runners, cyclists and golfers refuse occlusion for good reason. The Liberte compensates their loss while their ears stay open to traffic, teammates and the world.
Built on the world-renowned prescription fitting formula, delivering effective, evidence-based hearing compensation — not generic amplification.
DNN-driven noise suppression and voice enhancement isolate speech from wind, traffic and gym noise in real time.
The ear canal stays completely open — natural sound, zero occlusion and the kind of all-day comfort that keeps the device on the ear, not in a drawer.
Generates a personalized hearing profile — and the clinician dashboard lets you fine-tune a patient’s settings in seconds when requested.
Bluetooth 5.3 handles calls, music and podcasts — one device from the morning run to the afternoon conference call.
Fifteen minutes of charging yields 3 h of use, with 30 h total runtime from the case — enough for a training week between wall charges.
The secure hook keeps the Liberte planted through runs, rides and rounds of golf — a device your most active early-stage patients will actually wear, and the lowest-friction entry point in the Cearvol lineup.
