These are the first pictures of the Sony WH-1000XM4 wireless headphones. the much-anticipated follow-up to the company's popular WH-1000XM3 over-ear cans for their exceptional noise cancellation, convenience, and battery life.
The M4 was first discovered by Everton Favretto in photos of Anatel, Brazil's version of the FCC. That explains the lack of artistry. The most striking thing you'll notice is how similar (identical?) You look to the current M3s.
Fortunately, the Anatel file also includes a user guide that indicates changes inside. However, we need to be careful not to rely too much on the manual that comes with the package, as most of the specifications, including the weight and hours of use of the wireless, have been replaced with placeholders "XX" instead of the actual values. It is clearly a draft document.
Nevertheless, the M4s according to the draft manual improve compared to the M3s as follows:
- Bluetooth v5 (updated from v4.2)
- 2 W nominal power (from 8 W)
- 40 operating hours when connected via headphone cable and maximum noise suppression (from 36 hours)
- Something new called "Speak to Chat" that may make working with Google Assistant, Siri and Alexa easier (they now need a push of a button).
Bluetooth 5 and this lower power consumption should allow the M4 to work longer in wireless mode – much longer if they really use only 1/4 of the M3's power. This may not be a reason to upgrade from last year's Sonys, which already have great battery life, but it could make the M4 a very attractive buy if they keep the list price of $ 349.99.
