Review: Excellent for musician tinnitus - I am a professional violinist. I began having tinnitus many years ago: hearing the TV static “sound of silence,” plus occasional 10-second bouts of extreme ringing typically in the left ear. I put one of these earplugs in my left ear, which is just above the instrument as I hold it under my jaw. Hearing damage/loss in the left ear is a universal symptom of long-term violin playing, and additionally, the loud direct sound from being close to the instrument sometimes causes students (me many years ago) to limit themselves and avoid drawing the most sound from the instrument. This earplug solves both those issues: I still hear clearly at all volumes but am not overwhelmed when I play out, and my bouts of ringing have disappeared, and only come back when I forget to put the earplug in. I use this earplug whenever I play, indoors, outdoors, practicing or performing. I could go on about how useful this has been for me. After a couple minutes of being worn it fills the ear extremely comfortably, and I often (at least twice a week) forget to take it out after practicing, because I simply don’t realize it was in until someone notices the thing in my ear. This size is perfect for my ear, snug but not tight. I personally don’t use the case, I just slip it under the strap for my violin in its case. I believe these can last indefinitely until lost, which is a fine value for $10 each when I only use one at a time. I would recommend this to anyone who needs slight sound reduction of upper levels.

### ⭐⭐⭐⭐ Musician approved!
*by A***R on January 15, 2026*

Great sound reduction and fidelity! As a musician I need to protect my hearing and must be able to hear what I’m doing complete detail. These attenuators work very well considering the low price point. They’re not quite all-day comfortable, but otherwise I couldn’t be happier!
