The DUBS: Acoustic Filters

Haven't tried these myself, but thought I'd share. From The DUBS' site:

Finding the balance between blocking out harmful sounds while not making things so muffled that they are difficult to recognize can present quite the dilemma. That's where Dubs Acoustic Filters comes in, developed by acoustic engineers and designers, they are pre-tuned to target specific frequencies, reducing the volume without sacrificing that essential clarity. Featuring a 12 decibel Noise Reduction Rating, Dubs provides the opportunity to fully experience your surroundings without the threat of hearing loss.

The marketing people have beaten the engineering people here. 12dB is something, but most earplugs are getting around 30db. If they deliver flat response and I was mixing concerts a lot, I might give them a try, but for riding, you want the highest rating you can get in a comfortable plug.

After reviewing their site, they don't appear to deliver flat response, they are useless for mixing too. These things are just a bad idea.

Yeah, those cheap foam earplugs do the same thing.
