These are definitely not a pair of audiophile cans. Even though they are made to be portable and to be used with your iPhone (built in mic.) they are not that great at it neither. The main problem I have is that I bought these headphones to use when not at home. The issue is that they don't stay on my head very well. Isolation is another poor. Everyone will hear you a mile away when you listen to your music on these cans. They do look good on anyone wearing them but the best in their hard shell carrying case!!!! Basically useless piece of junk.
