hifi earplugs/earmuffs with more than 20 dB isolation?

[patalp]

Hey, I have a pair of hifi ety earplugs (20dB) and a pair of ear classic foamies (30dB). When I practice guitar at home or with my friends, the hifi plugs are great because they have even attenuation. However, when I goto a concert the foamies are the only choice. The hifi etys at 20dB are not enough at all. The problem is that the foamies take a huge chunk out of the trebles and mids and leaves lots of bass. So, I'm wondering if there are any earplugs, foamies, or over the head ear muffs that can block 30dB or more and are hifi/musician style (have even attenuation of all frequencies)?

I think you might have to go custom for more attentuation... I know Westone's customs do up to 35-40dB of isolation.

If you want earplugs that block a lot of sound try:

Advanced Musician's Ear Plug

They claim they are good musically also and have many testimonials on this page.

I use them for travel and sleeping in noisy environments and man do they work at reducing sound.
