[0024] There may be a fundamental limitation in the digital bandwidth provided by the Bluetooth wireless connection standard. The digital bandwidth for stereo audio transmission is approximately 1 to 2 Mbps. While this may be sufficient bandwidth for transmitting standard definition stereo audio data compressed by standard codec software (e.g., AAC, SBC, or aptX), this compression often introduces acoustic artifacts that degrade the perceived audio quality presented by the headphones. In addition, higher codec compression ratios may be required for new Hi-Res audio formats in order to provide audio quality beyond traditional standard definition or "CD quality" audio. Higher codec compression ratios produce more acoustic artifacts, eliminating any advantage provided by the higher audio sampling rates and bit depths of Hi-Res audio source formats. The impact of this fundamental bandwidth limitation has been well known in the headphone industry as consumers are preparing to purchase premium headphones to enjoy the audio quality provided by popular music servers such as Amazon. TM , Apple TM , Tidel TM and Qobuz TM) provided by high-quality wireless digital connections between headphones and music sources.

Modern wireless cellular transceiver technology (e.g., 3G, 4G, or 5G transceivers) can be integrated directly into the headset 30. This can overcome the digital bandwidth limitations imposed by, for example, using Bluetooth to carry audio from a mobile phone 14 to the headset 30. The significantly higher bandwidth provided by a cellular connection rather than Bluetooth eliminates the necessity for an audio data compression codec, allowing the user to enjoy full digital bandwidth and Hi-Res music quality. Although a Bluetooth connection may still be used between the mobile phone 14 and the headset 30, the Bluetooth connection may only be used to support audio from BluOS installed on the mobile phone.

BluOS TM Includes a software driver for initializing the cellular connectivity module with the user account information required to authenticate the headset system over the local cellular network. BluOS TM It also supports decoding music streaming services such as MQA TM 、OraStream TMand Apple TM ) provides a real-time Hi-Res audio decoder software component for the latest Hi-Res audio formats provided by BluOS. Although cellular wireless transceivers are associated with high power consumption, requiring larger batteries than are typically associated with headsets, recent silicon chipsets implementing 3G, 4G, and 5G cellular standards have been designed to significantly reduce the power and size of the battery required to support mobile headset applications.
