The JBL Tune 520BT headphones are a wireless on-ear model positioned as an affordable option within JBL’s Tune lineup. They feature Bluetooth 5.3 connectivity and are designed for everyday listening rather than premium noise-canceling use. The Tune 520BT delivers JBL’s Pure Bass sound profile and supports hands-free calling with Voice Aware technology, which lets users hear their own voice during calls. They charge via USB-C and are rated for up to approximately 57 hours of battery life on a full charge. The headphones are lightweight, foldable, and intended for portability and comfort. Customization options, including sound settings, are available through the JBL Headphones app.

The JBL Tune 520BT are lightweight on-ear headphones with a slim, foldable design. They have circular, shallow ear cups that are finished in smooth matte plastic. The headband is narrow with simple plastic hinges and adjustable arms. Each ear cup displays a small, clearly visible JBL logo, with one side housing low-profile physical buttons for power, volume, and playback.

To find the serial number on the BT series over-ear and on-ear models, the serial number sticker is on the inside of the headband, left side, visible when the size adjustment is pulled all the way out.
