Sony has yet to announce its latest flagship true wireless earphones, the Sony WF-1000XM5, but the omens are everywhere.

The latest of these omens came this week when a German journalist at WinFuture tweeted a European launch price of €319.99. This puts the Sony WF-1000XM5 at about $319 in the US and £287 in the UK.

Sony has not yet officially announced these earbuds, so we cannot confirm pricing details. Nevertheless, given that Sony's WF-1000XM4 is now available for $279 / €279 / £199 and that the price of everything has gone up over the past few years, we feel that this pricing is reasonable.

But Sony should be careful. Right now, Apple's AirPods Pro 2, the most famous of the true wireless earbuds, are available on Amazon for $199 (link to Amazon).

As for what justifies the higher price tag, there are rumors suggesting that the Sony WF-1000XM5 will offer better active noise cancellation, improved sound quality, and more powerful special features, some of which are supported by the earphones' FCC filing.

Of all the potential special features, the most interesting ones seem to be faster charging, longer battery life, and a contoured stem shape that fits more comfortably in the ear.

At this point, we do not know when Sony will announce the earbuds, although the evidence we have gathered so far suggests that they are likely to exist.
