I went to Target and bought the Philips HE592. Returned to my car, opened the package and hooked up the HE592 to my mp3 player. Muddy bass..terrible fake surround sound..just plain nasty. Repackaged and when back inside Target for a fast refund. These may look cool but they don't sound cool.
They do have wonderful 3D imaging. They are great for gaming. Not the best sound, but you can pinpoin stereo noises pefectly and you can even tell if its on the same level, above or below you if you have hardware 3d support on The EX71s don't do that.
