Care & Protect

Keep your gear healthy — diagnose channel problems, test your seal and hearing, and listen safely.

🔊 Start with your volume LOW and raise it slowly. Tones can be loud. Play a deep tone and push each earpiece gently into your ear — a good seal makes the bass jump in level.

Volume: 15%

If pushing the earpiece in makes the bass noticeably louder, your everyday seal is leaking — size up your tips or try foam. Confirm fixes in Fit & Tips (top box).

🔊 Keep the volume LOW. High frequencies can be sharp — don't crank it trying to hear the top end. Play each tone; the highest one you can hear is roughly your range.

Volume: 12%

Most adults stop hearing around 15–17 kHz; it drops with age, and that's normal. This is a rough by-ear check, not a medical test — and it's limited by your phone/IEM too.

Listening volume: 85 dB

Safe listening time: —

Based on NIOSH limits (8 hours at 85 dB, halving for every +3 dB). Phone/IEM volume isn't labeled in dB, so use this to understand the relationship — at high volume, safe time drops fast. When in doubt, follow the 60/60 rule: under 60% volume, under 60 minutes at a stretch.
