Sony WH-1000XM4: Updated Headphones Connect app confirms DSEE Extreme, Multi Point and Smart Talking Mode for US$349 and June-bound headphones

It has been a few weeks since Best Buy briefly published its WH-1000XM4 product page, confirming many details and the design of Sony's next-generation headphones. Previous leaks have also revealed that the WH-1000XM4 will support Bluetooth 5.0 and up to 40 hours of battery life with active noise cancellation (ANC) switched on. Additionally, the headphones will be powered by a MediaTek chipset, meaning that there will be no support for Qualcomm aptX or aptX HD.

Now, several details about the WH-1000XM4 have been extracted from the latest version of the Headphones Connect app. Updated earlier this month, the official changelog for version 7.0.1 teases that it is "Compatible with new models". Firstly, the WH-1000XM4 will support Adaptive Sound Control, a mode that automatically switches headphone settings based on location. This mode is not exclusive to the WH-1000XM4 though as it works on older models like the WH-1000XM3 and WH-1000XM2.

Based on the digging of @justplayinghard into Sony | Headphones Connect 7.0.1, the WH-1000XM4 will support DSEE Extreme, "Multi Point" and "Smart Talking Mode". Also found on the Xperia 1 II, Sony filed a patent for DSEE Extreme earlier this year. The company is yet to confirm what DSEE Extreme does, but presumably it is an improved version of DSEE HX. The latter is an algorithm that Sony claims "upscales your existing sound source (those lossy MP3s or AACs) to near high-resolution sound quality", so DSEE Extreme will likely be an extension of that.
