I've seen loads of different ways of improving Bluetooth connections in a pair of headphones in my time, but none quite as fascinating as the JBL Tour ONE M3. These headphones, just announced at CES 2025, promise to provide "the ultimate blend of innovative audio technology and seamless connectivity" thanks to a little box with a screen that JBL is calling the "JBL SMART Tx".
What does it do? The black box is a wireless audio transmitter which can be used to add Bluetooth to a device that doesn't feature the standard. You could plug into the USB-C port of a TV, for example, or the headphones socket of your airplane seat. The screen lets you control different device settings without having to dip into the app, such as EQ and broadcast to Auracast devices.
