Although Apple hasn't released any official word on the Powerbeats 4 wireless headphones, rumors and leaks about their existence have surfaced in recent weeks. Now they have even been seen on the shelves. As reported by 9to5Mac, a reader found the new Powerbeats 4 available for $149 at their local Walmart in Rochester, New York. It's unclear if this is the final retail price, as we'll have to wait for the official word, but the Powerbeats 3 launched for $199 (£169.95 / AU$259). < p lang="en" dir="ltr">@9to5mac @MacRumours the new Beats Powerbeats dropped without warning? These were found at my local Walmart in Rochester NY. pic.twitter.com/oiqDD20dcB14 March 2020 As you can see, the new version of Beats by Dre-branded Apple Wireless Headphones is available in the expected black, red, and white color options. They also show off the improved earhook design we've come to expect from true Wireless Pro Powerbeats. Similarly, the package claims the wireless earphones will have up to 15 hours of battery life, an increase from the 12 hours offered by the Powerbeats 3 and something we'd expect as the new units likely include Apple's H1 chip. The addition of this chip also introduces "Hey Siri" functionality (a detail discovered in the iOS 13.3 code), allowing users to directly access the Apple PDA via a voice command instead of having to wake up with just push a button. While this is about as clear a confirmation of the product as we can get without it being the official word from Apple, it should be noted that the tech giant hasn't made any official announcement on the matter. stage, so we haven't learned all the details about Beats' latest wireless headphones yet.
