Not looked one I AM FURIOUS! Mostly decorative but is warm. No, the device does not reconnect when back in range, at least not reliably for me to notice it tried to. We spoke to Amazons customer support and tried some quick fixes, but nothing helped. The pads stay put all day and you cant see a line through your pants when you wear them. Sometimes the left one won?t connect and both buds have to be put back in the case and pulled back out. If you like this review, do give it a thumbs up! These headphones proved me wrong and they really show that even after workout sessions, they truly are a top quality headphone material. It is plastic but I haven?t had any issues with the connections or the silicone straps yet so I think it?s a good product.
