Glasgow-based headphone maker RHA announces means to allow customers to use wireless headphones with just about any audio source with a 3.5mm or double 3.5mm jack-- the Wireless Flight Adapter.
While primarily aimed at use with in-flight entertainment systems (thus the name), the Wireless Flight Adapter is ideal to connect wireless headphones with devices such as the Nintendo Switch or a vintage piece of audio hardware. The pocket-size device promises up to continuous 16 hours of use on a single charge, and can stream audio simultaneously to two pairs of headphones.
