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.

Oppo says that the O-Free headphones offer four hours of music off a charge, with the charging/carrying case able to offer an additional 12 hours of listening time. And like the Find X, the O-Free comes in both red and blue color options to match its companion phone.

The O-Free will cost 699 Yuan (around $106 USD) when they go on sale in China later this August, but customers who are willing to shell out extra for the Find X Lamborghini edition will get a free pair of matching O-Free headphones bundled with the phone.
