Earplugs

Hello all,
Been super busy so I havent posted on here for a long while.

recently started playing with a new band.. Our rehearsal space seems to really accentuate the highs and mids (lots of glass and hardwood flooring)and these guys like to play pretty loud to begin with. I am a little concerned for my hearing.
Do you guys/gals know of a good brand of hi fidelity earplugs that will decrease the volume/ cut out the harmful frequencies without muddying up the sound?

I know what you need,but they are freakin expensive (over 120 Us THE PIECE/one ear)

Simple sleeping earplugs with -30dbs attenuation will do the job,search your local drug store/pharmacy

I use cheap Hearos with about 24db cut at shows as a spectator.

These one's seem more like what you want.

They say they are rated at -12db but act like -20db.

I bought mine a year ago at a local shop for about $20, and they attenuate these frequencies:

Frequencies(Hz)       125  250  500  1K  2K  3.1K  4K  6.3K  8K  

Mean Attenuation(dB)   6   21   29   32  27  19    20  31    38 

Standard Deviation(dB)1.7  1.7  1.6  1.6 1.8 1.9   1.8 1.8   1.7 

They're really not the most comfortable things in the world, but I can actually hear and separate out the bass, drums, vox, other guitar, it's just a lot quieter and more bearable, though it takes a while to sort of re-learn to hear. It sounds odd, but things sound more mid-rangey when you listen with them. Heavy duty plugs though, not throw away cheapo's. Unfortunately I can't remember the brand name! They didn't leave it on there instructions either XD
