DEVIA Pro1 are OWS Bluetooth headphones with a charging case. The headphones support OWS (Over-ear Wireless Stereo) technology – both earpieces connect to create a wireless stereo set. The portable case with a built-in battery, in addition to charging, allows you to safely store the headphones in your pocket, bag, or backpack. Free your hands and listen to music and internet radio while working, walking, exercising, or driving. DEVIA Pro1 OWS headphones are the perfect solution for users of smartphones, computers, notebooks, tablets, and other Bluetooth-enabled devices. They are compatible with most Android and iOS devices. The headphones also have a microphone, so you can easily make calls. The ENC function separates your voice from ambient noise, improving call quality. Talk/music time on a full charge is approximately 600 minutes (depending on volume level), thanks to energy-saving Bluetooth 5.3 technology. The headphones can be controlled using gestures. You don't have to interrupt what you're doing! Touch and go. Plus, stand out in style with a fashionable design.
