You are bidding on a pair of SONY Studio Monitor professional over-the-ear Dynamic Stereo headphones (model# MDR-7506). These would work well for a DJ. The headphones are wired, not bluetooth. There's a plug-in adaptor/headphone jack at the end of the cord. The ears are labeled R and L and they feature an adjustable headband for sizing. They have been tested and have incredible sound! The ear pads are showing a bit of age and there's a few scratches on the outer ear covering (please see photos #3 and #7) but otherwise these headphones are in great shape overall. Shipping will be based on your zip code and the weight of the box which is just over 1 pound when packaged. Please take a moment to view my other listings. Thanks so much for looking and happy bidding!
