Leaked images of the rumoredSonyWF-1000XM4 have surfaced online, showing off a dramatic design overhaul for thebest wireless earbudsyou can buy right now, theSony WF-1000XM3.

Posted to Reddit byKey_Attention4766(viaThe Walkman Blog), the images appear to reveal the packaging of thetrue wireless earbuds:

Based on the images, it looks like the Sony WF-1000XM4 will have a sleeker build than their predecessors, with rounder housings and what look like memory foam ear tips.

The gold Sony logo has also changed slightly, now appearing on the side of theearbudsrather than on the top. Meanwhile, a gold accented piece on the outside of the earbuds could be an external noise cancellation microphone, as The Walkman Blog speculates.

The Reddit user also posted some additional images of the packaging, which shows the claimed battery life of six hours from the earbuds themselves, and a further 18 hours from the charging case. That’s the same as the current-gen Sony WF-1000XM3, so you may be disappointed if you were hoping for a big improvement to battery life (assuming these images are legitimate, of course).

Other specs gleaned from the packaging include a Hi-Res Audio Wireless certification and a return of the active noise cancellation technology that made the WF-1000XM3 so popular.

Unfortunately, The Walkman Blog has been unable to verify the legitimacy of the images posted to Reddit, citing concerns with the font on the packaging and the placement of the Sony logo on the earbuds themselves.

As with any leak, it’s important to take these images with a pinch of salt. AsNotebook Checkpoints out, no reference to the WF-1000XM4 have been found on regulatory bodies, such as theFCC(Federal Communications Commission), so far, which usually provides a sign that a product is due to be launched imminently.

For that reason, we’re not expecting to see the Sony WF-1000XM4 for some time. In fact, it’s entirely possible that Sony will launch the fourth-gen wireless earbuds on the second anniversary of the WF-1000XM3, in July 2021.

Even so, it’s hard to not get excited about this leak. If Sony can match the success of its over-earWH-1000XM4, the brand could easily hold onto its crown as the best wireless earbuds manufacturer in the world – and with rumors of theApple AirPods 3and theAirPods Pro 2also circulating, it could be a very good year for wireless earbuds enthusiasts indeed.
