These are the first pictures of Sony WH-1000XM4 wireless headphones; much-anticipated company follow-up Beloved WH-1000XM3 The earmuffs are extremely practical with extraordinary noise cancellation, comfort and battery life.
M4 was first discovered Everton Fabreto In the photo published by the Brazilian version of the FCC Anatel. This helps explain the lack of artistry. The most amazing thing you will notice is how similar [same?] They look to the current M3.
Fortunately, the Anatel file also includes User manual This implies internal changes. However, we must be careful not to place undue reliance on the accompanying manual, as most specifications [including wireless operation weight and hours] have been replaced by "XX" placeholders for actual values. Obviously a draft file.
However, according to the draft manual, here are the improvements on the M4 over the M3:
- Bluetooth v5 [updated from v4.2]
- 2W rated power consumption [less than 8W]
- 40 hours of operation when connected via a headphone cable, maximum noise elimination [from 36 hours]
- A new feature called "talking chat" that might make it easier to use with Google Assistant, Siri, and Alexa [they now require a button press]
Bluetooth 5 and lower power consumption will make the M4 run longer in wireless mode-longer if they actually consume only 1/4 of the power of the M3. Maybe that's not the reason to upgrade Sony's long battery life last year, but if the M4 keeps its list price of $ 349.99, it could become a very attractive purchase.
