The Bose QuietComfort Earbuds II Truly Wireless are the next generation of the Bose QuietComfort Earbuds Truly Wireless. You'll want to check these buds out if you value noise isolation. Like their predecessor, they have an active noise cancelling (ANC) system that's worthy of their premium price. Bose has changed the buds' design, making them less bulky and more customizable, improving their overall comfort and fit. They're also the first to feature Bose's CustomTune technology, which calibrates their sound profile and ANC based on your ear shape.

The Bose QuietComfort Earbuds II are decent for office use. They have a comfortable fit for long days at the office, and their ANC tackles office chatter so that you can focus on your work. While their 6.7-hour continuous battery life may not last the whole day, their carrying case supplies an additional three charges, which is handy in a pinch.

The Bose QuietComfort 2 are Bluetooth headphones and aren't designed for wireless gaming. Their latency is also too high for gaming, as your audio and visuals won't be in sync.
The Bose QuietComfort Earbuds II are Bluetooth-only headphones; you can't use them wired.
The Bose QuietComfort 2 are good for audio reproduction accuracy. Their frequency response doesn't deviate much from their V-shaped sound profile, which injects extra emphasis into the bass and treble range for a more excited sound. The L/R drivers are amazingly well-aligned, with no major mismatches in amplitude, frequency, and phase, and group delay mostly falls under the audibility threshold across the entire range. These buds exhibit no audible coloration of audio through harmonic distortion, either, regardless of the listening volume.
The Bose QuietComfort Earbuds II are a great choice for noise isolation. While their isolation isn't quite on par with the very best ANC-equipped earbuds, the CustomTune technology adapts the ANC level according to your surroundings and does a solid job of tamping down on noises across the entire frequency range. They don't leak much audio either, so you can blast your tunes in public spaces without risking dirty looks.
The Bose QuietComfort Earbuds II have a disappointing microphone performance. While the built-in mic renders your voice in an intelligible way, it rolls off both the low and high end, making your voice sound quite boxy. It does a bad job of separating your voice from its backdrop, too, in both calmer and noisier environments.
The Bose QuietComfort 2 have excellent frequency response consistency. As long as you take the time to achieve a solid, comfortable in-ear fit, you'll be rewarded with consistent audio delivery.

The Bose QuietComfort Earbuds II are the next generation of the Bose QuietComfort Earbuds Truly Wireless. Their ANC blocks just as much ambient noise as their competitors, like the Apple AirPods Pro 2, and it's on par with their successor, the Bose QuietComfort Ultra Earbuds Truly Wireless. They're much more comfortable than their predecessor, thanks to the new design, which is less bulky and has ear tips and stability fins as separate attachments, allowing you to customize their fit.
If you're looking for more recommendations, check out our picks for the best noise cancelling headphones, the best noise cancelling earbuds, and the best wireless Bluetooth earbuds.
The Bose QuietComfort Earbuds II Truly Wireless and the Sony WF-1000XM5 Truly Wireless are both great pairs of in-ear headphones. The Bose are more comfortable, and their ANC can block out more background noise in the bass range, where you'll find the rumble of bus engines. In comparison, the Sony headphones have more robust sound customization features. They have longer battery life and support multi-device pairing and LDAC, which is Sony's proprietary codec for hi-res audio streaming via Bluetooth. They can also block out significantly more ambient sound in the mid to treble ranges, where you'll find noise like ambient chatter and the hum of an AC unit, respectively.
The Bose QuietComfort Ultra Earbuds are the next generation of the Bose QuietComfort Earbuds II Truly Wireless. That said, the differences between them are fairly minimal. Both buds share a similar sound profile that you can further tweak via the Bose Music app, and they're both equipped with Bose's excellent ANC technology. The QuietComfort Ultra are equipped with Bose's new Immersive Audio feature, though, which can help offset the poor passive soundstage performance that's commonplace with in-ear designs.
The Bose QuietComfort Earbuds II Truly Wireless are the next generation of the Bose QuietComfort Earbuds Truly Wireless. While both buds have great noise isolation, the successor's design has changed, and now the buds have separate fins and ear tips to help you get the best fit, making them a lot more comfortable. Their carrying case also holds an additional charge than their predecessor. However, the original gen have better build quality and feel less plasticky.
The Bose QuietComfort Earbuds II Truly Wireless are better in-ears than the Beats Fit Pro True Wireless. The Bose are more comfortable, have a slightly better noise isolation performance, and their continuous battery life is better. They also have sound customization features to help you adjust their sound to suit your tastes. That said, you may still prefer the Beats if you're an iOS user. They have an H1 chip for seamless pairing with your Apple devices and support Apple's Spatial Audio for a more immersive sound.
