Whether it’s for gamers trying to chat with friends during an online match or fitness gurus in need of an upbeat playlist during their morning workouts, the benefits of completely wireless headphones are obvious.
By eliminating the mangled wires and connecting the audio of consumer devices directly to the ear, you not only enhance the comfort and convenience of the headphone experience but equip the user with a much-desired level of freedom.
Yet in developing wireless audio, there are a multitude of concerns. Battery life, latency, and effectively maintaining audio connection are all factors that may make or break the user experience. Audio drop off, be it in a remote conference call or in the middle of a videogame death match, could be disastrous. Therefore, the question of wireless audio is not a question of why, but of how. How exactly can it be pulled off?
NXP’s NXH3670 has stepped up to answer those questions. Inspired by a wish to enhance gaming audio, this single-chip, wireless audio streaming solution delivers high performance, completely wireless audio communication. The NXH3670 Gaming and Communications solution provides robust, high-quality, and ultra-low latency audio and voice streaming with its optimized architecture, embedded DSP, and hardware support.

Flawless Audio
In order to avoid audio synchronization issues, a gaming headset requires extremely low latency. In the midst of a high-stakes virtual deathmatch, a split-second delay may give the upper hand to your rival. With an ultra-low latency of less than 20ms, the NXH3670 ensures that your audio is streaming to you in real time without any disruptions. The NXH3670 is also equipped with a robust interference avoidance scheme, which ensures a seamless connection even in the presence of Bluetooth and Wi-Fi interference.
Industry-Leading Battery Lifetime
While other wireless headsets may falter with high power consumption — constantly needing a recharge — the NXH3670 enables an ultra-long battery life. This is made possible by NXP’s efficient streaming protocol, which reduces the power consumption to 8.5 mW, the lowest active energy consumption in the market. This allows you to enjoy our seamless, continuous audio for hours on end.
Comfortable, Lightweight Design
The ultra-low power consumption of NxH3670 allows for comfortable and stylish headset designs which not only equip the user with the utmost audio quality, but with a sleek, lightweight, and incredibly comfortable look and feel — making it all the better to wear.
