Daddario PWPEP1

Wear on-stage, sound check and during rehearsals. Pretty comfortable despite I have piercing in ear channel. Damn good material - it sticks to your clothes so well that you're not afraid to lose these while aggressively headbanging :)

Though there are a couple of small drawbacks.
1. I have big ears. These protectors have 1 extra pair of plugs of a slightly different size. Though these are still a bit smaller that i would like to.
2. There's a cord to connect these plugs and hang these on your neck when not using. Though it was a real challenge to pull it on.
3. There are no replacement filters in case if you loose one.

Used these for the first time in the rehearsal studio last night. The difference between these tuned earplugs and standard "bung" earplugs is apparent the moment you put them in your ears. We're a loud band at the best of times and generally the bung types muffle all the sound, these are great though. It's like a very gentle but highly effective attenuation of the sound, bringing it down to a nice comfortable level where everything is clear. It's the first time I've been able to hear people talking clearly whilst wearing earplugs.
Never mind highly recommended, all musicians should buy these.
Seriously - buy these.
