JBL Tune 720BT Repair

The JBL Tune 720BT is a pair of wireless over-ear headphones released in early 2023, designed for everyday use like music listening, video calls, or commuting. It connects via Bluetooth 5.3, has 40mm drivers, and offers up to 76 hours of playback on a full charge. It also supports multipoint connections, so you can stay connected to two devices at once, like a phone and a laptop, without constantly reconnecting. The headphones come in a few color options, including black, white, blue, and purple, and are built with a lightweight, foldable design for easy carrying.

There’s no headphone jack on this model, so it’s completely wireless. While there haven’t been any official recalls, users have occasionally reported issues like Bluetooth connection problems or battery life declining after extended use. Most of these can usually be resolved with a reset or software update. The Tune 720BT follows the previous model, the Tune 710BT, and is part of JBL’s lineup of affordable wireless headphones.

You can identify the JBL Tune 720BT headphones by checking the model number, which is printed on the inside of the headband's left side or found on the original packaging. Some other key features the headphones offer is the four available color options (white, black, blue, and purple) and its lightweight, foldable design. The headphones are also entirely Bluetooth, meaning there is no headphone jack, which is another identifying feature.
