These are warm comfortable slippers that feel good and hold their shape well. This kit comes with extra wiring and hardware. I let them expand for a few hours before putting them up with 3M strips (no backing) and none have fallen off of the walls even with my kids have been playing with them and touching them so Im not sure using a backing is necessary. Also around ears is very comfortable, Ive worn other headsets where my ears will literally start sweating and I have to clean my ears like every 30 mins. Sound quality is OK. Floppy ?????? A very stylish looking set of headphones at a great price. They come with a TON of attachements to fit all ears and best of all they sound really good. Begeistert bin ich vom Eigenverbrauch: Mein Amperemeter sagt, dass diese Buchse im Standby (also beleuchtet und ohne angeschlossene Verbraucher) nur 2,35 mA verbraucht.
