Oppo has announced the O-Free, a pair of truly wireless headphones designed to pair up with the company’s recently unveiled sliding-camera equipped Find X smartphone.

The O-Free is built off of Qualcomm’s recently announced QCC3026 chipset, designed to make it easier for manufacturers to make cheaper truly wireless headsets without having to completely build them on their own (as well as being a cheaper option than Qualcomm’s flagship QCC5100 chipset, which it announced earlier in the year at CES.) The O-Free headphones will also feature Qualcomm’s TrueWireless Stereo technology for better power management and connectivity.
