The advertised product stated "EarPads Compatible Headphones:- Turtle Beach Stealth 400 450 500X 520 600 700 900- Ultrasone PRO-900, HiFi 780"I bought these earpads to replace those on my Ultrasone PRO-900. This omission feels pretty glaring given that this is most likely meant to be a "newbie friendly" bundle. These earbuds had a lot of positive reviews, so I decided to give them a try, 25 charger & 120 hours playtime was a nice feature, not having to charge them every day! I expected something shorter. I bought two of them and I?m glad I did. The nylon fabric is not flimsy and see-through like some cheap nightgowns, AND, the hem did not roll up in the wash, as it has on some bargain nylon nightgowns I have bought (and thrown away). Its a little snug, but it fits in there pretty good and I dont even bother putting in the cables or what ever, as my beats last about 39/hrs on a charge(use it for about 3/hrs round trip a day on my commute to work/home). Me, I still have not figured out how to lock it. I got these as a package deal when I bought a new Samsung phone so Im not sure about the price, but they are exceptional headphones. I will be bungee cording the bikes in addition to the provided clamps tho just as insurance.
