These days most mainstream audio electronics have Bluetooth connectivity built in. But if you have older home-audio gear, such as a beloved stereo receiver or a set of powered speakers, there’s a chance that either it lacks Bluetooth connectivity altogether or its Bluetooth reception is poor. That doesn’t mean you have to scrap your system and start over.
A Bluetooth audio receiver lets you pair your older gear with the latest Bluetooth audio sources—and the best ones give you great sound. The iFi Audio Zen Air Blue is our favorite due to its excellent range, exhaustive format support, and surprisingly good audio performance for the price.
