The NXH3670 wireless gaming headphone solution from NXP Semiconductors is in stock at Mouser Electronics. The ultra-low-power single-chip device is a 2.4GHz wireless transceiver with an embedded microcontroller and a proprietary audio streaming protocol to create a solution for gaming headset applications.

The device is Bluetooth Low Energy 4.2 certified and supports applications that require low-latency audio streaming.

It integrates an Arm Cortex-M0 microcontroller with NXP’s CoolFlux digital signal processor (DSP) core and hardware accelerators to support audio processing for streaming performance.

Ideal for applications requiring reduced battery size and extended performance time, the device boasts industry-low power consumption of just 8.5mW during audio streaming.

The NXH3670 runs a proprietary audio streaming protocol optimised for gaming headset applications to provide high-quality forward audio streaming at low latency of less than 20ms.

The device also supports a simultaneous 16kHz microphone backchannel and a bidirectional wireless data channel.

It is available in a compact 34-bump, 7.25 × 7.25mm WLCSP package ideal for space-constrained audio applications including gaming and communication headsets, wireless speakers, and wireless microphones.
