In-ear Headphone Advice Requested


I recently bought a pair of Audio-Technica M50 headphones, which sounded great for the price, but returned them because I didn't like the heavy, enclosed feeling of full-size, around-the-ear headphones. I now find myself wishing for in-ear headphones with sound quality similar to the Audio-Technica's. Does such a thing exist for a price that ordinary mortals can afford? I've listened to in-ear headphones that were very clear and detailed, but the music didn't have the "weight" that it had with the Audio-Technica headphones.

Suggestions appreciated.

I've owned a pair of Sleek Audio SA1's for several years & REALLY like the way they sound.They have a natural tone that allows hour after hour of listening pleasure & are not very expensive.What I like most about them though is that I mangled the cable a year or so ago & a replacement was readily available from SA for a nominal fee.Highly recommended!
I use the Yuin PK1 and PK2...both are excellent. PK1 needs a solid amp to really make them shine. PK2 will run off iPod amp without issues.

Thanks for the suggestions, everyone. I will look into some of them.

I already own a pair of Klipsch S4i earbuds, which are truly outstanding for the price (I paid less than $60) but pale in comparison with the full-size headphones I returned.
I'll second the Shure recommendation.I auditioned a bunch of brands all in an hour with my iPhone using the same three songs and they came out on top every time.
