One new headphone We acquired a bulk lot of these nice brand new Sennheiser HD 280 Pro headphones. See our other listing for 380 model Closed back super comfortable, great for studio / monitoring etc! Pouch not included unless you ask in advance, we may have some. Note these do NOT include a carry case nor original box. We have a few Black Sennhieser cloth pouches as shown that came in the lot, but not enough for all the headphones. If you would like a pouch, ask before bidding to see if we have enough left (otherwise the headphone will not include a pouch) Optional plug adapter not included unless you ask. We also have some 3.5mm to 1/4" adapters. If you need one PLEASE ADD "NOTE TO SELLER" box on your payment that you want one (otherwise headphone comes only with the 3.5mm plug) Note as these were bulk packed wrapped in bubble wrap, the foam earpad may have some dents, but should for the most part settle back into normal shape after unpacking and using a while, but could retain slight indentations. Guaranteed never used, worn, nor torn! And the nice thing is if you ever do wear out the pads they are replaceable and readily available .
