Etymotic HD5 Safety Headset and Earphones - Industrial Hearing Protection, Safe Listening Earphones, Yellow

Safe for hearing, even in high-noise environments. The eartips act like earplugs, so outside noise levels up to 108 dB (foam eartips) or 102 dB (3-flange eartips) do not significantly affect overall noise dose. Volume limiting technology protects hearing from unsafe sound playback, even at max volume on portable players. Use of these earphones at full volume on portable music players is within OSHA Permissible Exposure Limits for 10 ½ hours per day (52 ½ hours per week). With superb isolation and unrivaled sound quality, you'll hear your music as never before while protecting your hearing from overexposure!
