Bose QC35 headphones pair over standard Bluetooth, so a transmitter with a 3.5 mm source connection is the straightforward route for planes, gym equipment and older screens. The QC35 does not turn a transmitter’s aptX badge into an aptX connection, so prioritize reliable pairing, battery life and the right plug for the source.
