- Which has better noise cancellation, the JBL Live 770NC or the Bose QuietComfort 2nd Gen?
- The Bose. Its adjustable QuietControl and ActiveSense handle engine and cabin noise better. The JBL's adaptive ANC is fine for offices and streets but weaker on flights.
- Which lasts longer on a charge?
- The JBL Live 770NC, by a wide margin: up to 65 hours versus up to 24 on the Bose, or 18 with Immersive Audio on. The Bose quick-charges 2.5 hours of playback in 15 minutes.
- Is the Bose worth the extra money over the JBL?
- Yes if you fly often, wear headphones all day, or want wired USB-C lossless audio. If you mostly listen at a desk and charge rarely, the JBL at $120.00 at Star Promotion as of November 6, 2026 is the better buy.
- Which is more comfortable for long sessions?
- The Bose. It weighs about 0.51 lb against roughly 1 lb for the JBL, and its cushions are removable. The JBL's faux leather pads are fine but heavier on the head.
- Can I use either one wired?
- The Bose yes: USB-C audio up to 24-bit/48kHz and a 3.5mm-to-USB-C cable are included. The JBL Live 770NC is wireless only.
- Do either have water resistance?
- No. Neither the JBL Live 770NC nor the Bose QuietComfort 2nd Gen carries a water or dust protection rating, so keep both out of rain and sweat-heavy workouts.
