Also no software required, the mouses features all work right out of the box and plugged in. But even if the new ones arent long enough still, they include an extender kit. Pero el nivel del bluetooth es excelente. They are bass-heavy and on the warmer side, and a bit veiled on the upper register (as if treble and high-end clarity is slightly diminished). This is also maybe worsened by the fact that the headphones have that auto on feature so if they dont get completely seated or if they get de-seated from the 2 metal prongs in the case then it causes them to turn on and one headphone to die so then i have to charge just the one headphone again and that is why it probably seems like im not getting as much use other headphones in the past. Charging case is wireless which is a nice to have feature. Den Klapphaken habe ich sehr hoch moniert damit keine Jacke im Fußbereich des Bettes baumelt. Sinceramente não gostei, se pudesse ter experimentado antes não compraria, porém como precisava de um fone bluetooth não devolvi a compra. Looks decent. I received the slim strap sandal, not the original thicker strap that the photos show.
