How long does the battery really last?

JBL rates 50 hours with noise cancelling on and 80 hours with it off. Real-world figures depend on volume and codec, but this is among the longest-lasting over-ear headphones.

How does it compare with the older JBL Live 770NC?

The 780NC moves to Bluetooth 6.0 and Adaptive Noise Cancelling 2.0, with a similar 40 mm driver setup and long battery life. It is an incremental upgrade rather than a redesign.

Is the noise cancelling good enough for flights?

It handles engine drone and office hum well for the price, but it does not match premium ANC headphones. Voices and sharp noises still come through.

What comes in the box?

Expect the headphones, a USB charging cable and a carry pouch. A 3.5 mm audio cable is not confirmed for this model.

How long does it take to charge?

A full charge takes about 2 hours. There is no fast-charge figure published, so plan charging overnight.

Is the JBL Live 780NC worth it?

Yes, if battery life and a light over-ear fit matter more to you than top-tier noise cancelling. It is at the low end of its recent range, and only one store currently lists it new.
