Apple-owned Beats has a set of wireless Solo2 headphones in the works, according to new documents that recently passed through the US Federal Communications Commission.

The FCC documents don't reveal too much apart from the fact that the headphones are wireless. The original Solo2 headphones are wired and part of Beats' successful Solo range, with a wider sound range and enhanced clarity. Beats has claimed the Solo2 range is more dynamic than other Solo headphones, and that their frames are curved more to snugly fit the head.

The wireless headphones, which 9to5Mac first spotted via the FCC, are likely an updated or next-generation version of the Solo2 headphones, as the only difference between the two appears to be the Bluetooth 4.0 Low-Energy connectivity. The new model is also Apple-branded in that Apple is listed as a creator and a tester of the product.

The wired Solo2 headphones currently costs $199.99, and it's assumed a Bluetooth version will likely retail for more. It's unclear if the Beats logo will appear alongside Apple's logo on the packaging, but Apple's fine-print stamp does show up in the FCC papers.

Apple acquired Beats in August for $3 billion in a cash and stock deal.
