Excerpt: They are extremely comfortable, featuring a minimalistic headband and a unique capsule design, making them an attractive and lower-cost alternative to the HD 25-II. These are also suitable for nightly DJ use.
Pros: Clear Sound, Durable, Easy To Use, Great Price, Lightweight
Summary: I use my Sennheiser HD-25s for commuting. They are bigger than buds and canalphones, but smaller than the usual cans one would use at home or in the office. They are durable for sure, and have a split headband allowing one to adjust to one's head -- and they stay on your head quite well. You can rock with these phones. The HD-25s are a little uncomfy with a high clamping supra-aural factor, but with velour pads and some time, the discomfort is not a great.
Excerpt: Picked these up for DJing in loud bar. Super happy with the sound isolation, I was able to hear my cue clearly, while being able to feel the outside of the headphones rattling from the monitors. Bass response is massive, songs that sounded bass heavy in the cans, needed a little low-end push on the mixer. These headphones are super lightweight, which makes wearing them easy. I've owned other DJ style headphones and IMHO you can't beat these in this price range.
Summary: Very good for the money when it was on sale @ Newegg.
Pros: Sounds very good as promised. I'm not an audiophile but these do sound very good. Simple yet effective construction. Very very good sound isolation. I do not like high bass levels, and these are perfect for my taste. Feels very light on the head & travel friendly. Highly adjustable with regard to head sizes.
Cons: The cord goes from the right side of the headphone and becomes very inconvenient since i'm right handed (like most people), these get in my way of moving my mouse. As far as I can see, although the cord is unpluggable from the ear pieces, the right and left channels cannot be swapped since the right channel cord is always on the short end of the headphone (very hard to describe without seeing a picture, but take my word for it).
