Etymotic ER4S "earplug" will have you immersed in music!

Date of Review:  Dec 26, 2000
The Bottom Line: Excellent sounding earphones that are comfortable and truly isolates outside noise. For musicians/drummers wanting to protect their hearing, this is a worthy $270 investment.
Review: If I told you that I spent almost $300 on some earphones, you'd probably call me crazy. Many people do, so you're not alone. But those people don't understand why I walk around with a silly grin every time I listen to music with these Etymotic ER4S...

Etymotic 4S: $30,000 sound for $269

Date of Review:  May 21, 2002
The Bottom Line: Sound resolution like no other, isolation which only enhances that and a low price for the sound quality. In my experience, my favorite headphones so far.
Review: Hello.

I feel it would be most fruitful to compare the Etys to some established hi-fi leaders in the headphone realm.
