Rumors are swirling about the highly anticipated Sony WH-1000XM6 headphones, and leaked FCC documents are fueling the speculation. These filings suggest an imminent release, revealing details about the upcoming model's Bluetooth capabilities and hinting at significant design improvements. The documents indicate support for Bluetooth 5.3, offering faster and more stable connections. However, the inclusion of features like LE Audio and the LC3 codec remains uncertain.The leaked illustrations accompanying the FCC filings point towards a redesigned headphone structure. This potentially includes easier earcup replacement, addressing a common complaint about the XM5 model, and possibly a more compact folding design for improved portability. While the sound quality is expected to remain exceptional, leveraging the same 30mm drivers as the XM5, potential tweaks to bass and treble are anticipated. Speculation points towards a late April or early May release date, but this remains unconfirmed. A possible name change away from the numerical convention is also being discussed.
Pros And Cons
- May have Bluetooth 5.3
- Potentially easier to remove earpads than XM5s (due to repositioned markings)
- Possible design updates to earcups, earpads, and hinge (based on illustration)
- If using the same drivers as XM5s, likely to have good sound quality
- Bluetooth low energy support doesn't guarantee Le Audio or LC3 codec support
- Doesn't guarantee support for Auracast
- If using same drivers and tuning as XM5s, may have more bass and treble than preferred by some

Imminent Release and Leaked FCC Documents
Rumors suggest Sony's flagship WH-1000XM6 headphones are on the verge of release. Leaks from the Walkman blog indicate Sony has filed documents with the FCC, hinting at a new wireless noise-canceling stereo headset. The timing of these filings, along with accompanying illustrations, strongly suggests the mystery device is indeed the XM6.

These filings reveal details including Bluetooth 5.3 support, confirmed by test reports for both Bluetooth Classic and Low Energy. However, it remains uncertain whether features like LE Audio or the LC3 codec will be included.

Potential Design Improvements
The FCC filings include an illustration possibly showcasing a design update. Specifically, the placement of information labels suggests a more accessible design compared to the XM5, potentially making earcup replacement easier. This could resolve user complaints regarding difficult earcup removal on the XM5 model.

The illustration also reveals subtle differences in earcup and hinge designs compared to the XM5. While not confirmed, this hints at improved ergonomics and possibly a more compact folding design, addressing another common complaint about the XM5's non-folding design.

Sound Quality and Codec Support
If the XM6 utilizes the same 30mm drivers as the XM5, the sound quality is expected to remain excellent. The XM5 performed well in SoundGuys' MDax testing, achieving a 4.2/5 score. However, some users found the XM5's bass and treble slightly overemphasized, something Sony might address in the XM6.

Regarding codec support, the use of a Mediatek chip rather than a Qualcomm chip, which is necessary for aptX, makes aptX support unlikely. Sony's continued prioritization of its LDAC codec further reduces the probability of aptX inclusion. However, a surprise inclusion of a Qualcomm chip and aptX support is still possible.
Potential Release Date and Branding
Based on the FCC confidentiality agreement's expiration date of July 22nd, 2025, and comparing it to the XM5's announcement timeline, a late April to early May release for the XM6 is speculated. This is purely speculation, however, and should be treated as such.

There's also speculation about a potential name change, moving away from the numerical naming convention. Sony's recent rebranding of its XB line to the 'ALT' line suggests a possibility of the XM6 being marketed under a new 'ALT ANC' branding.
Conclusion: Worth the Hype?
The Sony WH-1000XM6 headphones promise several improvements over their predecessor, the XM5, based on leaked information. Potential design enhancements, such as easier earcup replacement and a more compact folding design, address common criticisms of the XM5. While maintaining a similar high-quality sound signature is expected, minor tuning adjustments are hoped for.
Ultimately, whether the XM6 is worth the purchase depends on individual priorities. Users seeking design refinements and possible improvements in comfort and portability will likely find the XM6 appealing. Those satisfied with the XM5's sound and design might find less incentive to upgrade. The official release and further details will be essential in confirming these speculations.
