Bang and Olufsen melds some popular Bluetooth earbud features plus dust-and-splash resistance with its high-end audio smarts for the new Beoplay E6 wireless earbuds announced at IFA 2018. They can also charge via a dongle while you're using them, which is good since they're rated for only up to five hours of play time and it takes two hours to fully charge them.

They come with a variety of silicone ear tips and fins to help you customize the fit.
