(Product purchased from DISCOUNT DISCS) Very good sound, bass flawless (despite what some have said / read) as long as you avoid equalizers "bass boost" or other "megabass". Sold with a bag and adapter 3.5-> 6.35mm. When folded and put in his bag, helmet occupies about 13x10x5cm; the headset can hold (more or less) in a pocket of your pants. The mute function has been withdrawn since a long time (ca deteriorated from some of the specifications). The headset looks quite frail but comes with lifetime warranty Koss. It can be worn on the head and behind the neck (unlike what some reviews suggest) as you astutely switch the hoop backwards (what's forgotten to do commentator concerned ;-p ). Fast delivery with DISCOUNT DISCS (3 days in total to Bordeaux) and especially offered. At that price, do not hesitate long.
