On August 7, it was reported that Sony released their new generation of wireless noise reduction headset WH-1000XM4 last night.

The WH-1000XM4 is still consistent with the previous generation of WH-1000XM3 in appearance design, with two colors of black and platinum silver. The main upgrade point is the HD noise reduction processor QN1 (more HD prefixes than the previous generation), which can process the collected sound signals 700 times per second, further improving the noise reduction performance; The equipped multi microphone system can better recognize speech and filter background noise.

The WH-1000XM4 has a built-in 40mm dynamic coil unit and is equipped with LCP diaphragm, which supports LDAC audio transmission coding. Upgrading DSEE Extreme (advanced version of digital sound enhancement engine) can more effectively compress the high-frequency signals lost during the process, presenting better audio range performance.

In terms of functions, the WH-1000XM4 has a new pick free dialogue function (an ambient sound mode to enhance voice pickup), and supports the multi-point connection function - it can maintain connection with two devices at the same time and switch quickly; The right earmuff is still equipped with a touch panel, which can be used to cut songs and adjust the volume by clicking or sliding.

In terms of endurance, the WH-1000XM4 supports 30 hours of continuous playback when noise reduction is turned on, the headset supports fast charging, and can support 5 hours of continuous playback after 10 minutes of charging.

The WH-1000XM4 is priced at 2899 yuan by the Bank of China, and is currently open for pre-sale. It will be delivered on August 18, and the official trade in activity will also be launched - the WH-1000XM4 can be purchased by using the old 1000X series headphones before October 8.

On the whole, because the previous generation WH-1000XM3 has done quite well and excellently in the field of headworn noise reduction earphones, the WH-1000XM4 has a relatively limited upgrade in terms of hardware and functions. Of course, there are only a few function points that can power the earphones, and sometimes manufacturers are also squeezing toothpaste.
