I hear a lot of people talk about the Sony's but when I'm buying headphones im looking at the durability factor. It makes no sense buying $100+ headphones and then they dont stand up fairly well to the rigors of being dropped, cord pulled etc..
I am testing out a pair of ******* Monitor 8's, not the best in sound quality, they keep the outside noise out, and they seem darn well durable.
-removable and replaceable headphone cord.
-Comes with 2 headphones cords.
-metal head band
-headphones adjust using a screw mechanism (that means no sliding & having to readjust the headband to fit your head)
I've been using it thursday through sunday for about 4 months now and not a sign of breaking or anything like that.
Like I said..with any headphones, the biggest thing is durability. You can find tons of headphones with noise cancelation and well defined sound, but the question is how many of them will last after you shell out $100+ ??
