The player is clean, its knobs are good. It comes with a Bluetooth module, its sound is clear and loud, same as the player that has factory Bluetooth. The Bluetooth module alone cost me 80 and it's out of the market. The only note is a burn mark on the player, which is a manufacturing defect in the Optima 2015 player. I don't have a fixed price. I won't disappoint the serious buyer. Contact via WhatsApp or private message. I won't answer calls.
