“ Update: Reduced design rating due to ever-tangling cable. The cable is MADE with some type of built-in twisting/tangling design flaw. Just holding the headphones in my hand, the cable wants to twist and turn and due to its material, it's never fully "straightened out" like most other headphone cables. Due to this, it's become unusable. I've owned the original Bose IEs and now bought these...” --xx0xx
“ Really a horrible set of headphones for the money. I got these way back as an upgrade from stock ipod headphones and was blown away by the bass. At the time all I wanted was bass and boy did they deliver. At the time I loved them but as my music interests grew and expanded so did my realization that I had horrible headphones. Last year I picked up a set of AWEI ES-Q3 off...” --kitten wizard
“ I've tried out several pairs of in-ear phones and never got used to the feel of them. These are much more inviting straight away, as several earpads of different sizes are included. I found my size and was off to the races. The cable is a bit short, and I usually have to bring the included extension cable along with me on my commute. This is not a problem, just an...” --phallumontis

“ I looked around for a review on these and didnt find many, so bought a pair and heres what i found out. - Nice build quality - Good comfortable fit - Worst cable design I have ever seen (wtf were they thinking?!) - Easy to be driven - Extremely well defined mids & highs (these are not laid back and softsounding!) - Good soundstage...” --fabiosouzajr
“ First off, there are counterfeit Bose IE flooding ebay like crazy, so buyers beware. It would be smart get yours from an authorized dealer. (In my case, I bought them used from a local friend who got them at best buy). The comfort is great and I dont find them falling out of my ears. No isolation to speak of, the tips dont seal, and they arent designed to isolate. The build...” --EYEdROP
“OK so this headphone has been a trial for me. I bought with high hopes as I was looking for a AH-D7000 equivalent in in an IEM and in this case a $90 IEM, not a small order! So the question is did it achieve my goal and is it a worthy $90 contender? To answer my first question I can say it's not my D7000 but it does a VERY good job of coming close and is worth trying for anyone looking...” --dweaver
