Product arrived all skreaced because the builder did not protect the parts in a propped way inside the box that was ok and without any damage. the sound quality was okay, but every time i moved the cord there was static. Note: you MUST download the firmware update and install it in order to have the best sound from the speaker. Battery life: Decent, but be prepared to top them off with a quick-charge during a break or at SOME point during your workday if you work an 8-hour day and listen at any reasonable volume. Was looking for an unusual towel rack and who would have thought of a wine holder! Its definitely stout enough to protect the buds. you can unplug and plug the mic, which is a good thing. This one works fine, though it has a fine-grained texture all over the footbed, which you can feel when you put it on. I threw my phone in one of my back pockets of my pants and this new version ensures you dont lose connection no matter which way you turn your head. Also the two front door slats seem to be really flimsy and the slightest pressure on them could lead to them breaking.
