Summary: Have had these monitors (headphones) for a few weeks now and have no complaints. The sound is full and rich across the spectrum and were a steal for $40. Tested and reproduces sound from 18hz on up faithfully! Planned to use with my laptop and home stereo but have been impressed with performance from my cell phone as well. Adapter is large as most monitor connectors are so wont fit phone if it has a case.
Summary: I bought these because they have a large range and the sonys with the same range were 120.00 dollars. They work great and are very comfortable on the ears. I did have to lift the head strap up with some twisty ties because I didn 't like it on top of my head. But I would definately get them again and would recommend them to others.
