Apple's Beats Solo 3 Wireless headphones are regular visitors to our headphone deals pages because they've been out for a very long time: they were launched in 2016, and other than a few colour updates they haven't changed since. They still sell because of their excellent battery life, which delivers up to 40 hours of listening time, and because of the big B on the side. But they've fallen far behind the best headphones in their price bracket. Which is why Apple appears ready to launch a new version at last.
There hasn't been an official announcement yet but MacRumors contributor Aaron Perris has found multiple references to and images of Beats Solo 4 headphones in the latest release candidate of iOS, which Apple issued yesterday. And they give some good indications of what's coming, including an important audio upgrade.
