Summary: I purchased 2 of these headsets - 2 years apart... BOTH had similar problems with the cords recoiling and having issues with them tangling without any reason except that they were molded into the headsets improperly... VERY upset and will never buy Sennheiser again..
Summary: I spent $15 on these and don't think they are worth 1/4 of that. (This review very much considers the low sounding price.) Way too much mid bass, no real low bass, top ens sounds like you are listening to them through 3 down comforters.
Pros: long cable comes with cable management system (cable wrap) efficient (will play louder than most at given setting) not as funky looking as many Sennheisers
Excerpt: I bought this a few months ago and there are already problems with the sound (alternating from one ear to the other). I previously owned Sennheiser headphones which I bought for twice the cost of this model and they did the same thing. Serves me right I suppose.
Summary: These headphones have a serious design flaw. Believe me I have bought 4 pairs of these headphones and they always break in the same position just after the two year warranty is up. Where the cable attaches to the driver unit is the problem area. I have uploaded a picture to show the problem.
Summary: As mentioned in other reviews the wires are very thin and come away from the ear piece easily. I've had mine around 6 months and after noticing the sound had stopped in the left side speaker I discovered that the wires had come loose.
Summary: I have used these headphones quite infrequently over the past year, maybe once a week max and the wires have completely come loose connecting to the headset, useless! Wouldn't recommend them-my friends bought similar range headphones for the same price which it seems are actually fit for purpose...
