Input:
I'm an audio enthusiast.  Highly critical of the sounds I listen to and through the headphones delivering the highs, mids, and lows.  These are very good headphones.  Not the best but perform solidly.  Nice isolation of removing the outside noise... but really warm low ends (deeper bass response) and nice mid and high end frequency responses.  I have heard many headphones... Sony MDR-V500's, MDR-V700's, and MDR-V600's.  These offer a suitable replacement without the high cost.  These headphones could easily double for DJ use or reference listening purposes.  They are well constructed and most of all comfortable.  The single wire conncetion to the left side makes them even more less likely to tangle and are reinforced to make sure they last a long life.  Lifetime warranty included.  Hmmmmmm. We'll see.  Initial impression?  Very surprised by the cery good sound and affordable pricing.
