Sony WF-1000XM4 Test | Chip

Sony WF-1000XM4 Test | Chip

The Sony WF-1000XM4 provided the longest battery life in our test. We got better results without ANC when using Bluetooth standard codec SBC. In this case, the headphones ran straight for almost 14 hours without recharging, and lasted nearly 50 hours, including recharging via the battery case. During the test, these are the best values Leaderboard. With ANC, battery life is reduced to just 9.5 hours or 32.5 hours at a time. These are the best values.

Additionally, WF-1000XM4 charging very quickly after this short charging time of fifteen minutes they can play music again for 5.5 hours without ANC or over 3.5 hours with ANC again. Last but not least, the positive Bluetooth connection we evaluate positively. This is because the Sony WF-1000XM4 has the highest Bluetooth range in our leaderboard environment and continued to play music without any problems during testing despite a closed door between the player and the headphones.

However, you should note that in terms of battery life, this will vary depending on the device and the codec. For example, with ANC and Sony’s HD audio codec LDAC, they only ran for about 6 hours and 20 hours. By default, the WF-1000XM4 selects SPC or AAC (depending on the mobile phone), but if you change the standard layout of the app from “Priority to Fixed Connection” in favor of “Priority to Sound Quality”, you may have to reckon with significantly lower battery life, but in the end They are even better.

Wireless charging according to Qi standard is included. For this, Sony has canceled the NFC connection function. But because WF-1000XM4 supports so-called fast pairing, the headphones will appear immediately in the connect menu without working your way through the settings menu. So can be distributed with NFC.

Incidentally, Sony uses the current Bluetooth 5.2 protocol here. Like its predecessor and fourth-generation headphone, the XM4 in-ear does not have OptiX support, but rather uses the best AAC or Sony’s LDAAC in addition to the Bluetooth standard codec SPC. This may be disappointing for some, but in our experience, especially for streaming music from popular AAC or SBC services, it is perfectly adequate.
