the headphone jack wont fit in the audio port on my Sony MDX headphones. Its a bliss to have these pair. GET A SECOND COPY and play 7x7 kingdoms, for even more challenge and a deeper level of strategy! Worked great ?? (0x00050005)[ 2880. put it back in the protective bag or on a headphone holder when not in use. which for me the X10 is great dissapointment. I was a little weary purchasing Birkenstock?s on amazon, but they are authentic. EDIT: Well it has been nearly a year since Ive been using this fightstick and its still going strong, I continue to stand by my initial review. they lasted about 2 weeks of 5 minute there 2 minute there of wearing them, mild use.
