Chinese audio brand Lang Zhu has announced the launch of its new A7 Max over-ear headphones, now available on JD.com for ¥229.
The A7 Max headphones are designed for comfort and immersive sound. Weighing approximately 280g, they feature an ergonomic headband with a 120-degree rotating hinge structure to ensure a comfortable fit that doesn’t clamp the ears. The earcups combine space cotton and protein leather, aiming to provide both breathability and effective sound isolation.
Innovative Audio Technology
A standout feature of the A7 Max is its integration of the C-Media 2206 chip, which Lang Zhu claims is a world-first for this type of product. This chip supports high-resolution audio playback at 32-bit/192kHz and delivers 7.1 surround sound, boasting a signal-to-noise ratio of no higher than 104dB. For clear communication, the headphones are equipped with a 360-degree detachable microphone featuring AI noise reduction and a one-button mute function.
Gaming-Focused Features
The headphones utilize 50mm beryllium-titanium diaphragm drivers, promising a rich and detailed audio experience. For gamers, the integration of TACTI-LINK technology is a significant draw, offering ultra-low wireless latency reportedly as low as 10ms. This ensures that audio cues are delivered in real-time, crucial for competitive gaming.
Powering these features is a built-in 1500mAh battery. A practical addition is the support for charging while in use, meaning gamers and users can continue their session without interruption during charging.
