We are pleased to announce that as of August 13, 2015, Qualcomm Global Trading Pte. Ltd., a subsidiary of Qualcomm Incorporated, has completed its acquisition of CSR plc. For more information, please see the press release .

Our heritage in wireless connectivity and extensive portfolio of audio technologies allows us to continually innovate and to work with our customers to deliver cutting-edge soundbars, speakers, headsets, multi-room audio, gaming controllers, smart remotes, PC peripherals, and accessories, like 3D glasses.


Leading brands like Bowers & Wilkins, Philips and Logitech turn to CSR to solve the challenges their customers really care about - sound quality, low latency, low power, and seamless connectivity – so that they can get on with the business of creating popular high performance products.

In audio, music and control, our innovations enable connected ‘home entertainment ecosystems’ that deliver a superior listening experience and seamless connectivity for consumers. 

CSR’s aptX® audio codec has revolutionized Bluetooth® Stereo. It delivers superb sound and fully synchronized audio content, ensuring that the on-screen movement matches audio – essential for gaming applications and maintaining good lip-sync on soundbars.

As content changes, consumers are increasingly demanding advanced forms of control such as voice command input and motion based input. CSR offers end-to-end wireless connectivity solutions for remotes with Bluetooth Smart (low energy) technology, which delivers rock-steady, non-line-of-sight connectivity and a dramatically extended battery life. On the Host side, ‘instant on’, ensures the device is always ready to go immediately when picked up. By also offering solutions for 3D glasses, gaming controllers and other input devices like keyboards and mice, CSR is unique in offering a full 'ecosytem' to customers.

And with leading expertise in all aspects of Audio and Control, from keeping the lowest latencies to glitch-free audio in the toughest of RF environments, CSR’s silicon and software technology platforms are easy to integrate, speed time-to-market and help meet the rapidly evolving needs of consumers.
