Mcdodo Dynamic TWS is a bluetooth in-ear 5.0 TWS earphone with charging box. The headphones support TWS (True Wireless Stereo) technology – both headphones are connected together to form a wireless stereo set. A portable box with a built-in battery, in addition to the charging function, allows you to safely store the headphones in your pocket, bag or backpack. Free your hands and listen to music, internet radio while working, walking, training or driving. Mcdodo TWS headphones are an ideal solution for users of smartphones, computers, laptops, tablets and other devices that support Bluetooth technology. They are compatible with most Android and iOS devices. The headphones also have a microphone so you can easily make voice calls. The duration of call/listening to music on a full charge is about 300 minutes (depending on the volume level), thanks to the use of Bluetooth 5.0 energy saving technology.
