After testing the Sony WF-1000X6 for several weeks, my initial impression upon unboxing them hinted that this review was inevitable.
This isn’t my first experience. When Sony’s last top-tier wireless earbuds, the WF-1000XM5, were released, I published a piece identifying a single aspect I’d modify – and it wasn’t the noise cancellation.
While I appreciated their sound quality and active noise cancellation, I didn’t find those earbuds as comfortable as some competing models available at the time.
Upon learning that Sony had refined the design of the new WF-1000XM6 during their February launch, I was eager to see if it would enhance comfort. However, my enthusiasm waned when I realized Sony was retaining the identical eartips.
For those unfamiliar with Sony’s eartip evolution in recent years (a topic I’ve regrettably tracked), allow me to provide some context.
Sony first introduced these specific eartips with the WF-1000XM4 in 2021. In our WF-1000XM4 review, we noted, “Crafted from polyurethane, which has a silicone-foam hybrid feel, Sony states these tips ensure a more secure and stable fit. The numerous minuscule air pockets within the tips are also designed to aid in noise reduction and dissipation.”
Initially, only three tip sizes were available (small, medium, or large) to achieve a proper seal. With the WF-1000XM5, Sony added an extra-small tip, likely catering to users with smaller ear canals who found the existing sizes uncomfortable.
However, for the XM6, there’s no change. While an extra-large eartip could be beneficial, I suspect my discomfort stems more from the material choice than the size itself.
The problem is, it’s neither true memory foam nor pure silicone. Sony’s chosen hybrid material simply lacks sufficient pliability. I don’t believe the earbud’s shape is the cause, as they conform nicely to my inner ear’s curve. Instead, it feels like the tips exert pressure, often requiring extra adjustments to achieve a proper seal.
A quick glance through the What Hi-Fi? stockroom reveals numerous wireless earbuds that offer immediate and more consistent comfort.
Apple’s AirPods Pro 3 feature updated “foam-infused eartips,” incorporating “a new layer of foam-infused microspheres” that feel somewhat thicker and more robust. I’ve used them and found them appealing.
Similarly, I find Bose’s shallower, less rounded silicone eartips excellent. They don’t insert as deeply as some competitors but still provide the sensation of adequately sealing the necessary parts of the ear.
Furthermore, the tips on the Award-winning Technics EAH-AZ100, though somewhat bulbous, have a relatively thin dome, which also doesn’t cause me any irritation.
After consulting other members of our review team, it seems I’m not alone in my slight uncertainty regarding this matter. Statistically, many other users are likely to share this sentiment.
To be clear, once you achieve a correct fit with the Sony earbuds, the performance is excellent. However, it’s crucial to remember that ear shapes vary, and fit is ultimately a matter of individual preference.
My main issue is spending excessive time adjusting the fit before each listening session, often asking myself, “Is this right?” It’s not that the fit is awful, but I can achieve a secure fit with competing earbuds more rapidly.
This isn’t a deal-breaker that would deter me from purchasing or recommending them. Nevertheless, I believe Sony should reconsider the eartip material for its subsequent premium earbuds.
Curiously, I’ve encountered none of these problems with Sony’s more affordable wireless earbuds, none of which utilize this specific type of tip. Perhaps that’s a direction worth exploring?
