Abstract:
Shortly after launching a new generation of flagship wireless headphones WH-1000XM6, Sony unexpectedly brought another blockbuster new product to the majority of audio enthusiasts - WH-1000XM4C head-mounted noise-canceling headphones. This new model is not simply a technological evolution, but an innovative replica based on Sony's classic noise reduction benchmark WH-1000XM4 that has been widely praised in Sony's history, integrating modern functions and configurations.
Since Sony launched the WH-1000XM5, its new non-foldable headband structure has triggered a lot of discussion among consumers. Many long-term users have always been obsessed with the compact and portable body shape of the XM4, which supports compact folding and storage. The most eye-catching highlight of the WH-1000XM4C released this time is that it fully retains the XM4’s acclaimed four-way foldable hinge structure and iconic ergonomic outline, allowing users to easily fold it and stuff it into a compact hard-shell storage bag, which perfectly solves the core demands of portability for commuting and travel.
While retaining the retro essence, Sony has comprehensively modernized and reconstructed the internal core hardware and functional architecture of the headphones. WH-1000XM4C has been upgraded to the latest USB-C high-speed charging interface, which not only supports a faster high-power fast charging protocol and can support hours of continuous playback in just a few minutes of charging, but also completely opens up the USB-C lossless audio direct connection function. Users only need to connect a mobile phone or computer with a Type-C data cable to obtain zero-latency and uncompressed high-fidelity digital audio signal transmission, while retaining compatibility with the classic 3.5mm analog audio interface.
In terms of connectivity and interaction, the new phone natively supports the new generation of Bluetooth multi-point connection technology. Users can seamlessly switch audio streams between multiple devices such as laptops, tablets, and smartphones without the need for repeated pairing. In addition, the built-in microphone pickup system of the headset introduces the AI noise reduction algorithm and deep neural network beam forming technology from the updated flagship model, which significantly improves the clarity of voice calls in noisy outdoor, windy or public transportation environments.
In terms of acoustic performance and noise reduction level, WH-1000XM4C continues Sony's classic QN1 high-definition noise reduction processor and dual noise sensor architecture, and has made modern corrections in the tuning style. The low frequencies are tighter and deeper, and the mid-to-high frequency resolution of human voices is more transparent. When active noise reduction is turned on, the headphones can still provide a long-lasting battery life of about 30 hours, and the battery life is further extended when noise reduction is turned off.
Sony officials stated that the birth of WH-1000XM4C is a direct reflection of the brand listening to feedback from the core user community around the world, and aims to provide a no-compromise option for users who value folding portability but also desire modern charging specifications and excellent communication experience. The headphones will be officially launched for pre-sale in major global markets in the near future.
