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.
Until now, Sony WH-1000XM series headphones cannot maintain connections with multiple devices simultaneously. Multi Point on the WH-1000XM4 changes that, but XDA Developers notes that the headphones cannot use LDAC when Multi Point is enabled. The WH-1000XM4 will be able to maintain a connection with two devices, according to the Sony | Headphones Connect 7.0.1 app.
Additionally, the WH-1000XM4 will support a "Smart Talking Mode". When enabled, the headphones will automatically adjust ambient sound levels when a nearby voice is detected. This mode seems similar to Quick Attention, which Sony included on past WH-1000XM series models. Hence, it is unclear whether this will be present on the WH-1000XM4, too.
No leaks have mentioned when Sony plans to release the WH-1000XM4. However, its confidentiality agreement with the FCC expires on June 1, 2020. Sony could extend the agreement between now and June 1, but the appearance of Best Buy's product listing and updated Headphones Connect app containing references to the WH-1000XM4 suggests a launch is imminent. The WH-1000XM4 is expected to launch for US$349.
