I was looking for some I.E.M.'s to use while playing my drums in my
basement home studio. I was looking for something with good sound and
isolation so I didn't have to blow my ears out trying to hear myself
playing.

After doing some research myself I wound up purchasing a pair of Shure
E-3's. From reading tonnes of product reviews, everyone who has
purchased them have been satisfied. I considered the E5's but after
seeing reviews of folks who purchased E5's then went back down to the
E-3's for comfort and even sound reasons. I was skeptical at first
about any "ear bud" type earphone (have yet to hear any that are
decent). The Shures were worth every penny.

I am by no means a "pro" when it comes to this stuff so this is
strictly an opinion. I am happy with them. I even bought an
additional pair!

Hope this helps.

Cheers;
Steve
