Ultra-low Power, Low Latency Audio for Wireless Gaming Headphone
The NxH3670 constitutes a highly integrated, single-chip ultra-low-power 2.4 GHz wireless transceiver with embedded MCU (Integrated Arm® Cortex®-M0 processor), targeted at wireless audio streaming for gaming headphones, delivering low latency audio and ultra-low power consumption.
The NxH3670 runs a proprietary wireless audio streaming protocol which has been optimized for wireless gaming headset applications, providing high-quality forward audio streaming at low latency (<20ms) combined with a simultaneous voice microphone backchannel. Additionally, a wireless bidirectional data channel is available.
While primarily designed for headsets, this solution can also enable wireless audio streaming for household and office devices like soundbars, wireless speakers, wireless Subwoofers and more.
Overall, the NxH3670 delivers a small form factor with long battery life while reducing overall weight and size.
