Wolfson Introduces a Mass-Market Noise Canceling Stereo Headset Reference Solution Incorporating Its Unique myZone(TM) ANC Technology

Press release date: February 10, 2010

Edinburgh, UK - Wolfson Microelectronics today introduced the myZone(TM) WM182, a stereo ear-bud headset reference solution, delivering Wolfson's unique feed-forward Ambient Noise Cancellation (ANC) technology in a mass-market headset. This product can be quickly and easily customized and branded by the world's leading consumer electronics companies, including mobile phone manufacturers.

The USB rechargeable WM182 is a superior, cost competitive, 'white label' ANC headset, which is ready to be re-packaged, according to customer design requirements, and delivered to the consumer in-box or as an after-market accessory.

Delivering noise canceling technology at a competitive cost, this headset enables millions of consumers worldwide to experience Wolfson's unique ANC technology, in a convenient portable headset.

Wolfson's unique myZone(TM) feed-forward ANC technology results in crystal clear audio by eliminating background noise, removing the need for consumers to increase the audio volume to compensate for external noise. With headphone volume levels undergoing EU review, the WM182 provides manufacturers with a solution that prevents hearing damage caused by listening to loud music for extended periods, while delivering HD quality sound.

Rash Sahota, VP and General Manager of ANC and Software Solutions at Wolfson Microelectronics, commented, "Combining 25 years of semiconductor expertise with a leadership position in Ambient Noise Cancellation, Wolfson is able to offer customers a cost-effective, market-making, high quality consumer product, which has the potential to shape the direction of the global headset industry. Wolfson developed this headset in response to customer requests and its introduction to market is a natural evolution of Wolfson's world-class ANC technology and semiconductor devices. Wolfson will continue to use its tried and tested fabless model to support this ground-breaking ODM activity."

Delivering up to 99% noise cancellation*, the WM182 features an in-line control pod containing a rechargeable Lithium-ion battery, which provides around 30 hours of ANC playback; mini USB charge socket; call answer/end button; ANC on/off switch; and two color LED status indicator for power and charge. It also features a noise sensing microphone in each ear-bud, plus a voice microphone.

Many customers, including multiple Tier 1s, have sampled and are currently evaluating the headset. Wolfson will introduce a range of additional complementary headsets later this year.

*Wolfson test environment. Up to 99% noise cancellation across frequency range 60Hz - 5KHz. Peak ANC of 30dB. Greater than 20dB noise cancellation from 60Hz to 1.5KHz.
