Summary: I debated between these and the 428 and ended up getting these because the reviews said the sound quality was better. I really wanted the isolation that a closed can offers, but in the end I didn't want the thin chord and I didn't want to sacrifice quality like I did with my Skull Candies (which...
Pros: Sound quality for the price is outstanding. I paid just about the same price for a pair of Skull Candy cans and they can't compare to these. They are very, very comfortable and I can wear them all day with no fatigue. Delicious bass and mids.
Cons: The chord is very, very long. I have to keep it wrapped with a tie, but it's just an annoyance. More annoying is the 5 inch plug (incl. adapter) when I plug into my laptop or PC jack. And the adapter is NOT iphone friendly, which is a bummer, but I'm not going to walk around with these all that m...
Pros: At 30 dollars, these headphones can't be beat. I bought these things YEARS ago, like in 2003 or 2004, and they lasted until a few months ago, and that was because I mistreated them. They are comfortable, durable, and most importantly, they sound good.
Cons: At 30 dollars, none. At 70, it might be worth paying the extra 30 to get the 555's.
Summary: For private home use, these would be an great first step into the realm of real audio... but as far as listening to music in the workplace, stick with something that produces a little bit less noise.
Pros: Amazing sound quality. This is my first set of good headphones that I've ever owned. It gave me a whole new perspective on the music that I listen to.
Cons: It seems that they are leaking A LOT of sound to the outside. From another person's point of view, it seems like I'm listening to the music VERY loudly, but the music I'm hearing is not much louder than what other people close to me are hearing.
Summary: I bought these cans after listening to it in a store. Immediately I was convinced. It has good bass,mids and highs. It`s not the perfect headphone, but it has nothing bad either. I love just the way it is. After 100 hours burn-in it sounded better, not much but better ;)
