Stronger Noise Cancelling and Improved Aware Mode

Bose’s second-generation QuietComfort Earbuds build on the original’s noise-cancelling pedigree with a smaller design, more personalized tuning, and newer wireless tech.

They’re designed for commuters and frequent travelers who want the strongest possible ANC in a true-wireless form without sacrificing comfort.

The CustomTune system now runs each time you place the earbuds in your ears, measuring your ear canal and calibrating both noise cancelling and sound output to match. This delivers more consistent ANC performance and more balanced audio, regardless of how you insert the tips.

Noise cancelling itself is stronger and smoother than before, with a more natural Aware Mode for letting in ambient sound when needed. This makes the QC Earbuds II more versatile in everyday use, shifting easily from complete isolation on a plane to situational awareness on a city street.

Bluetooth 5.3 connectivity also improves wireless stability and efficiency, reducing dropouts and lowering latency compared to the first-generation model.

Stability Bands Replace Fins for a More Secure Fit

Bose has also slimmed down the physical design in this generation. The earbuds are smaller and lighter, and the charging case is noticeably more compact than the first model. Instead of the older wing-style fins, the QC Earbuds II use stability bands in three sizes alongside multiple ear tips to help achieve a better seal without adding bulk.

This makes them easier to pocket and more comfortable for extended listening.

Despite the smaller footprint, the earbuds still carry an IPX4 rating for water and sweat resistance. That means they can handle workouts and light rain without issue, although the charging case itself is not waterproof. For users who want to take premium ANC earbuds to the gym or on the go, the combination of a tighter fit and splash resistance adds peace of mind.

Strong ANC Earbuds Even Better

With a slimmer design, personalized tuning, and even stronger noise cancellation, the Bose QuietComfort Earbuds II refine almost every aspect of the original model.

They still don’t offer high-resolution codecs or the longest battery life, but for travelers and commuters who prioritize comfort and class-leading ANC in a true-wireless form, they remain one of the strongest options on the market.
