Not bad headphones. You have good things and bad things. They are comfortable to wear and do not irritate. The controls and volume are easy to find in the dark. Sound quality is good (not great). Bass isn't that much but it sounds okay. My friends report that there are no problems with the microphone and they can hear me well. The bad thing is that the microphone isn't really movable. It is where it is and you cannot move it or throw it aside. The only movement it has is to swing straight up and slot into the left earcup. They definitely feel a bit bulky compared to some other headphones. Overall these are good headphones that work great. Does it cost $40? I am torn. I think for $30 I would recommend it, but for $40 there are much better options just another $5-10.
