Vertu Constellation Adds aptX® Low Latency Support for Seamless Wireless Audio Streaming

Highest audio quality a necessity for luxury smartphone brand

Cambridge, UK and San Jose, California, USA – CSR plc (LSE: CSR; NASDAQ: CSRE) today announces that Vertu, the world’s foremost luxury mobile phone manufacturer, has chosen CSR’s aptX® Low Latency audio compression codec to ensure its latest smartphone, the Constellation, delivers high-quality Bluetooth® stereo audio, with a delay of under 40ms. This ensures seamless audio/video synchronisation for video and gaming as well as providing the high quality wireless listening experience that aptX users have come to expect.

The handset, now available at selected stores, allows users to stream audio over a Bluetooth connection to aptX-enabled wireless speakers and headsets, while maintaining CD-like audio quality that is crisp and clean.

“Vertu places great emphasis on craftsmanship, engineering and technology” said Massimiliano Pogliani, Vertu’s Chief Executive Officer. “We aim to deliver a unique sensory experience to our customers and by choosing aptX, we are ensuring that they will enjoy a superior wireless listening experience when playing audio from their Vertu Constellation.”

“The Constellation is an exciting luxury product whose owners will have high expectations,” says Anthony Murray, Senior Vice President, Business Group at CSR. “It is a visually striking device made from high quality materials, so the audio quality needs to be just as impressive. The aptX logo is a sure sign that the phone will deliver on this front and the fact that Vertu has chosen to support it is a reflection that the technology is the audio codec of choice for high-end consumer devices.”

The prestigious brand is the latest to join the ever-expanding aptX ecosystem, a community that now boasts over 200 high-profile manufacturers such as Samsung, Sony, Monster and SMS Audio. These manufacturers all use aptX across a range of audio devices including smartphones, tablets, wireless speakers and headsets to enhance the wireless listening experience.
