Solid is the key word here.The goods:Firstly, the sound performance of these headphones are solid. The sound they put out is crisp and clear with the bass coming out sharp. You can easily turn off that nasty EQ stuff on your iPod/iPhone/Android/PC...you just don't need the Bass boost with these.  I was listening to my music at a higher bit-rate compared to the nasty ole MP3s, so if you want to test the performance get a "lossless" format to test. (don't blame crappy sounds on crappy music format)  I digress, these are great sounding headphones.Secondly, the build of these headphones are solid. You are going to have to be pretty hard on these headphones to break them; normal use even through travel these should hold up a long time.The bads:I knew going in that these weren't active noise canceling, so I wasn't expecting a miracle. They are good for blocking some noise, my old Bose over-the-ear phones performed about the same. So Noise-isolating might be stretching it a bit...they block more sound just by being over your ear.They are heavy...solid construction yes...but they are heavy.Alternate Comfort:  On my head for a few hours at a time, they were just fine. Though for me, I at times wore around my neck, and these are not comfortable; so if you imagine yourself wearing them around your neck at all they are not good.Wrap-up:For the price these are absolutely great headphones; the sound alone competes comparably with the more expensive phones out there.
