This headset is lightweight, foldable, and comfortable. You can use bluetooth (which allows to use the play / pause, change volume, forward / backward, and taking calls directly through the headset buttons) or wired (cable supplied) that disables the buttons (as the headset is off), but the merit of not to use or the headset battery, nor that of the device (smartphone, PC .. which uses a lot bluetooth). Charging is with the same charger as a smartphone or tablet (micro-usb, which is obviously provided but you can use one of your other devices). It takes about 3 hours to fully charge, which will hear many hours of music (for me I have charged that 1 time in 1 month and a half while I average 3 uses 4h per week). I tested the headset to a PC (Windows 8), surface 2 tablet (Windows RT) and smartphone (LG G3) both bluetooth and wired. The little difficulty (not indicated in the notice) is that for the pair with the smartphone, we must remain pressing the on / off button when turned on until it blinks alternately white / blue ( this may sound silly, but it took me a while to understand it). The headset is comfortable, and completely surrounds the ears, the material is nice. The height of the earphone is adjustable. And the main thing: I find it very good sound.
