Versatile CD Playback: This portable CD player supports CD, Bluetooth in & out, USB playback and an LED display, with Aux-in and headphone jack for flexible listening. Bluetooth out lets you connect external Bluetooth speakers during CD mode, while Bluetooth in works with most Bluetooth-enabled smart phones, tablets and music devices (Bluetooth 2.1 or above). The built-in 3000mAh lithium battery provides around 4 to 6 hours of playtime on a single charge, and the included remote control makes operation easy from a distance (control range up to 10M/30FT). Type-C charging keeps it ready to go wherever you are.
