Premium Bluetooth headphones that are designed for superior comfort and the ultimate crystal-clear stereo sound reproduction. They are compatible with mobile devices that support Bluetooth, but also have AUX capability so they can be used with a cable. Onyx\’s active noise control (ANC) function reduces unwanted ambient noise to improve sound quality when in a louder environment. The volume and track are able to be changed directly from the headphones and they have a microphone that allows the user to receive and make phone calls. They can be recharged from any USB port or a mains
adapter and are beautifully presented in an elegant EVA carry case with a Micro-B USB cable, a 3.5mm AUX cable and an instruction leaflet.
