Jbl Authentics 300 Bluetooth Speakers - Black

Damaged speaker, sticky dirt around the buttons on top, Bluetooth doesn't work with a mobile phone at a distance of 20cm, only works with the mobile phone on top of the device or underneath, and didn't make the Bluetooth connection to an Audio-thecnica Bluetooth vinyl player. Disappointed, disappointed with the experience of my first purchase from BackMarket. I've already returned the equipment. The speaker isn't even worth 50 euros. I was completely ripped off.
