Ajuda para JBL Tune 760NC Repair: aprenda a consertar com as próprias mãos.

The JBL Tune 760NC is part of JBL’s line of wireless, over-ear noise cancelling headphones, designed for everyday use with long- lasting battery life and active noise cancellation (ANC). Launched as a more affordable alternative to JBL’s premium headphone models, the 760NC gained popularity for its balanced sound quality, strong bass, and comfortable design- all offered at the mid-range price point.

JBL has been producing audio products since 1946, and the Tune 760NC continues JBL’s tradition of quality consumer audio by catering to music lovers, commuters, and remote workers looking for wireless freedom without sacrificing audio performance.

With Bluetooth 5.0 support, voice assistant support, and up to 50 hours of battery life with ANC off, the 760NC is designed to be reliable and convenient. However, like many devices powered by lithium- ion batteries, long term use can lead to charging or power issues, which this page and its associated troubleshooting guides aim to address.

The JBL 760NC can be identified by the device serial number and barcode on the box. There should be a clear product name engraved on the rubber flap and compliance icons on the speaker cover.
