Sony WF-1000XM4 are rumored to be tracking the best wireless in-ear headphones you can buy right now Sony WF-1000XM3 – and as new leaks occur, the hype is full around these potential class leaders in-ear headphones.
An upcoming Sony pair of wireless noise-canceling headphones model number YY2948 is also FCC (Federal Communications Commission) and Bluetooth SIG certified, and if the code name really matches the Sony WF-1000XM4, we can book several major upgrades.
Of course, we need more than unconfirmed images and the FCC archive to confirm the existence of the Sony WF-1000XM4, but so far here’s all we know about the rumor earbuds, as well as all the things we would like to see.
Go for it
- What are they? A new pair of Sony wireless in-ear headphones.
- When will they be released? Possibly in June 2021.
- How much they cost? Probably about $ 230 / £ 220 / $ 399.
Sony WF-1000XM4 release date
Currently, the Sony WF-1000X4 doesn’t have a solid release date, but we think their release is pretty immediate as it’s been a year and a half since its predecessors were released. In fact, the headphones could even be triggered in June.
The FCC archive, which we believe refers to the Sony WF-1000XM4, originally announced a date on September 27, the date on which short-term confidentiality expires – a typical indicator of when a company will officially disclose a product – but now that date has been updated to June 9.
It makes sense for Sony to wait for the 2021 release date if the company wants to see Apple compete. The technical giant is rumored to be launching Apple AirPods 3 and AirPods Pro 2 at some point this year, and in particular the latter may be a competitor to the Sony WF-1000XM4 as they are likely to include active noise reduction.
The fact that images from the packaging of the Sony WF-1000XM4 have been leaked also suggests that the release date may be coming soon – although, as we mentioned, these images have not yet been confirmed as genuine.
Sony WF-1000XM4 price
Again, there is no word yet on how much the Sony WF-1000XM4 will cost, but we would be surprised if the company deviated too much from its predecessor’s price.
When it launched, the Sony WF-1000XM3 cost $ 230 / £ 220 / $ 399, although prices have since fallen as the buds age.
Sony WF-1000XM4 design
From the pictures, it looks like the Sony WF-1000XM4 has the sleek design of its predecessors, rounder casings and looks like the tips of a memory foam ear.
The entire round case can be touch-sensitive, unlike the Sony WF-1000XM3, which has a special touch-sensitive area that allows you to control music playback, call the device’s voice controller, accept or reject calls, and switch to Instant Attention mode.
The golden Sony logo has also changed a bit and is now visible on the side of the headphones and not at the top. Meanwhile, a gold-accented song outside the in-ear headphones could be an external noise-canceling microphone, as The Walkman Blog speculates.
Lately Walkman blog naked the images according to it are prototypes of the Sony WF-1000XM4. If genuine, they’re likely to reflect the final design (albeit with a slightly rougher and more finished look) and are in line with the leaked images we saw in February, giving extra weight to the legitimacy of the leak.
The Walkman blog also revealed leaked images of the WF-1000XM4 charging case and stated that its slightly higher output value (5 V at 140 mA instead of 120 mA) could indicate a slightly faster loop charging speed in the case.
There is also speculation that the case can be downloaded wirelessly Sony’s upcoming flagship Xperia 1 III.
Using the USB-C port as a guide, The Walkman Blog has estimated the size of the new charging case to be around 60x38x28mm (WxDxH), which is much smaller than the WF-1000XM3 case, which measures 78x62x28mm.
Sony WF-1000XM4 rumored features
Again, the details of the features expected of the Sony WF-1000XM4 are a bit thin in the country, but a few breakdowns have been collected from the pictures of the packages sent to Reddit and recently FCC archiving.
The prototype of Sony’s upcoming wireless noise-canceling headphones, model number YY2948, is certified with the FCC (Federal Communications Commission) and Bluetooth SIG, and if the code name really matches the Sony WF-1000XM4, we can be in stock for several major upgrades.
The most important of them is that the use of Bluetooth 5.2 gives real wireless in-ear headphones better battery life due to lower power consumption and higher bandwidth for data transfer – also enabling better sound.
At the same time, the compression images sent to Reddit suggest a return to active noise reduction technology, which made the WF-1000XM3 so popular, and it is likely that the Ambient Sound and Quick Attention modes will also appear.
The package also includes Hi-Res Audio Wireless certification, which means they could support Sony’s high-resolution LDAC codecs alongside the AAC and SBC codecs already supported by XAC.
There had already been side sounds that the Sony WF-1000XM3 would get a Hi-Res Audio update after the in-ear headphones appeared very briefly on the Qualcomm aptX website, described as ‘aptX HD enabled’. This post was quickly taken away, but not until it was noticed Walkman blog.
Since the post came out in March 2020, and we haven’t heard anything since, it’s possible that Sony will record aptX HD support for the WF-1000XM4.
However, a recent FCC archive that may refer to Sony’s in-ear headphones reveals a new MediaTek MT2822S chip that is said to bring an enhanced digital signal processor (DSP), hardware ANC, forward microphones, voice prompts and a smaller overall footprint.
Using MediaTek and not Qualcomm with the processor may mean that the Sony WF-1000XM4 again bypasses aptX and aptX HD support. However, Walkman blog believes that higher power ratings may be an indication of LDAC support – which was a significant shortcoming in XM3.
Sony WF-1000XM4: what we want to see
While information about the Sony WF-1000XM4 is leaking coins and crumbs (Sony hasn’t really confirmed their existence yet), we’ve had the opportunity to dream a few things we’d like to see in the fourth-gen genuine wireless in-ear headphones.
Support for 360 Reality Audio
We want Sony to deliver the WF-1000XM4 with some features of the Sony WH-1000XM4, their ears to their siblings (and the best headphones 2021).
One of these features is support 360 Reality Audio, which is Sony ‘s own embedded audio technology. Designed to put you right in the middle of your music, the technology places individual instruments on a virtual ball, making you feel like your favorite songs are coming towards you from all angles.
In addition to giving 360 Reality Audio support a new way to experience your music, the WF-1000XM3 could become a true competitor to AirPods Pro, which supports Apple’s own Spatial Audio technique
DSEE Extreme sound scaling
Another feature that Sony could possibly borrow from the WH-1000XM4 is the scaling of DSEE Extreme sound. This AI processing seems to restore details from lossy compressed formats and bring clarity to lower quality formats and files, and we were impressed with its features when we tested the WH-1000XM4.
Talk to the conversation and auto pause
Again, voice chat was introduced alongside the Sony WH-1000XM4 and we would like to see it done once again with the WF-1000XM4. This feature allows the headphones’ built-in microphones to detect when you have started speaking and pause your music while compensating for ambient noise that is channeled to your ears.
When it comes to pausing music, we want Sony to turn on auto-pause when you remove one in-ear headset. It’s something we’ve seen from many wireless in-ear headphones on the market, and it looks like a simple upgrade.
Better battery life and wireless charging
With every new generation of genuine wireless in-ear headphones, we want to see an improvement in battery life. The Sony WF-1000XM3 currently offers six hours of self-looping and another 18 hours of charging case, and models such as Lypertek PurePlay Z3 have proven that much more is possible these days.
Saying that if the images leaked from the earbud packs are justified, it looks like the battery life will not be changed at all.
Another simple upgrade that Sony could make is the introduction of wireless charging features. That’s something that the Apple AirPods Pro does as standard, and as more and more people buy wireless charging worms, it seems sensible to allow these users to charge without a cable.
