Bonne durée de vie de la batterie ! Wish I had found them sooner. I had some Tao-Tronics but the battery became unreliable after a year (fair enough for the price)I?d say the sound is a little better than the Tao and I like the cable management that goes round the back of the neck. Android, it has been a HUGE step BACKWARDS ! De ser necesario las puedes usar todo en día sin que te molesten I searched online for ways to "soften" Teva straps, but did not find much in regards to. I tried wearing them thinking back strap would stretch and move forward so my foot could go all the way in my shoe. The soundbar has BlueTooth capabilities, so Ive paired it with my phone and often use it to play music. The mouse itself has Bluetooth 3. Just a rule of thumb, you only need the threads to engage the equivalent of the diameter of the axle, aka 5mm is a typical skewer diameter.
