I don't like the 2.5 mm jack on the end to the wire for it, and the wire is to short. I have a couple of devises that don't have Bluetooth and I need a longer wire for. I have longer audio cables that have 3.5 mm on both ends. Now I have go out and buy adapters or new wire with 2.5 and 3.5 ends. I bought the 720's for the price now I am spending more money to get them to work for the all the devices I want to use them for. The charging cable is too short too but I do have longer ones that work.
