- How long does the battery really last?
- JBL rates it at up to 76 hours. Expect less with active noise cancelling on, since ANC drains power faster than plain Bluetooth playback.
- Is the noise cancelling good enough for flights?
- It cuts steady engine and traffic noise, but JBL's Tune-series ANC is less strong than on premium models like the Sony WH-1000XM5 or Bose QuietComfort.
- Can I use it wired?
- The listing describes it as wireless with Bluetooth. Check the box contents for a detachable audio cable if wired listening matters to you.
- How does it compare with the JBL Tune 770NC?
- Both are Tune-series over-ears with ANC. The 780NC is rated for much longer battery life, so pick it if charging less often matters more than saving money.
- What comes in the box?
- Expect the headphones, a USB charging cable and a quick-start guide. A carry case and audio cable are not confirmed for this model.
- Where is the JBL Tune 780NC cheapest?
- At Newegg, for $224.99, as of our latest check.
