headphones

 

These have a nice price point. pretty much every headphone I select will have a unimatch plug, though this severely limits the price range of the headphones: most of the higher-end headphones have a 1/4" plug. for stereos: If you are going to buy a set of headphones for use in a stereo, I would rather you start out by trying one of these on, than with paying for a $20 cheapie. spend the money - you will get a far better sound experience and much better bass and high-end response. Don't expect them to be noise-cancelling though. I think they are still worth it for use on stereos and keyboards. I had nice success with Sony MDR-600V.
