The full-size closed under $200 category is a very popular one among pro’s and casual listeners alike. The most similar competitor to this I own is the Beyerdynamic DT770 Pro 250Ohm. I will make some comparisons to this and the smaller on-ear Sennheiser HD 25-1 II which I also own.
Pros: Outstanding audio reproduction for this price point and class.
Summary: I have owned a pair of these headphones for six weeks now. Initially I bought them to cope with office noise. I work in a large, open cube farm with a great deal of white noise and a constant cacophony of conversation.
These 'phones have surpassed my expectations since day one.
Pros: Inexpensive, no obvious flaws in the sound reproduction, very good noise isolation, foldable
Cons: Very tight fit initially, the stock cable is heavy and bulky
Summary: Initial impressions: They can't reproduce the tone of a bass guitar correctly, let alone a human voice. Estrange thing is that they aren't sibilant or anything, but some mysterious peak between upper-mids and treble make some instruments like cymbals and female voice sound too unnatural and away...
Pros: Level of isolation, Comfort, Fit, Efficiency, Bass extension, Good mids and highs
Cons: Lack of mid-bass hump can bother some (not me)
Summary: This was recommended to me by a friend and because of the other great reviews on the web I purchased a pair. What I can say is that it really brings out the details in music. Those low bit rate MP3's will not sound too good now. Bass is not exaggerated and highs are nice and smooth.
Pros: Good amount of detail and also great passive noise isolation.
Cons: They will not sound good unless you use high quality sources. Minor coloration.
