Colour: Gloss Black | Interface: Wireless

Be aware that earbuds happen to produce feedback noise when in your ears... Pretty uncomfortable to be fair. This happened with JBL Live Beam while placing them in the case, bun never in ears. Possibly can be fixed with the firmware update.
Other than this (which happens quite seldom, once or twice in the last month), everything is so good about them, shape, volume, battery life.
