Bose QuietComfort Ultra Earbuds (2nd Gen)

Bose QuietComfort Ultra Earbuds (2nd Gen)

The Bose QuietComfort Ultra Earbuds (2nd Gen), released in summer 2025 (with full availability around September 2025), are Bose’s latest flagship true wireless noise-cancelling earbuds. They build on the original QuietComfort Ultra Earbuds (2023) with targeted improvements while retaining what made the first generation a top contender: industry-leading active noise cancellation (ANC), rich sound, and comfortable fit.

Key Features and Improvements

• Noise Cancellation: Widely regarded as the best-in-class ANC among earbuds. The 2nd Gen refines adaptive ANC for smoother transitions and better performance in Aware (transparency) mode. It effectively blocks low-frequency rumbles (e.g., airplane engines) and high-pitched noises.
• Sound Quality: Powered by Bose CustomTune technology, which calibrates audio and ANC to your ear shape. Features Immersive Audio (spatial audio with head-tracking) for a wider, more natural soundstage. Sound is described as rich, balanced, and detailed—excellent for music across genres.
• New in 2nd Gen:
  • AI-powered noise suppression for significantly improved call quality.
  • Wireless charging support for the case.
  • Multipoint Bluetooth connectivity (connect to two devices simultaneously).
  • Minor tweaks to Aware mode and overall ANC refinement.
• Battery Life: Up to 6 hours per charge (4 hours with Immersive Audio on), with the case providing up to 24 hours total. IPX4 water/sweat resistance.
• Design and Fit: Chunky but secure fit with silicone eartips and stability bands (multiple sizes included). Touch controls are responsive (and can now be disabled).
• App Support: Bose Music app for EQ, shortcuts, firmware updates, and mode customization.

Pros and Cons (From Reviews)

• Pros: Unmatched ANC for travel/commuting, immersive and enjoyable sound, comfortable for long wear, reliable controls.
• Cons: Bulky design (not the smallest buds), battery life lags behind some competitors (e.g., no improvement over 1st Gen), premium price.

If noise cancellation is your top priority (e.g., frequent flyers or noisy environments), these are often recommended as the best available. They edge out competitors like Sony WF-1000XM5 in ANC, though sound preferences are subjective.
