We got our hands on the Optoma NuForce BE Free8 before launch, and we're impressed. Fans of truly wireless earbuds should take a look!
A reliable pair of wireless headphones to soundtrack your run or gym session.

With both Apple and Google dumping the headphone jack you may be in the market for some wire-free earbuds, the BE Free8 from Optoma may be the ticket.
Basic-but-good truly wireless headphones
