I normally use it to carry my headphones in a bag. I have the Numark electrowave, M-audio M40 and M50, Sol Republic Air wireless, and SkullCandy Crusher wireless. I normally use the Crusher wireless as my headphones to listen to music. The others normally stay at home. So I normally use it to store them. I sometimes even use it to carry my wallet and phone when I'm going out. The description said that it can be used with most headphones if I remember correctly but I find that its a tight fit for like most of the headphones that dont fold. I have to force them in which I dont like. The Sol Republics dont fit. The headband is too long. On the bright side, it looks really good and durable. I like the lining on the inside and the little pocket to store cables. The zipper also is still going on strong, no problems there. Looks really nice. A must for headphone lovers.
