Bose QuietComfort Noise Cancelling Earbuds II review: Noise-canceling masters

Bose recently launched the second generation of noise-cancelling earbuds, the QuietComfort Noise Cancelling Earbuds II. It has a compact body, and while it is more portable, the manufacturer has now deepened the noise reduction experience, bringing a great comprehensive user experience. After a brief experience, what do we have to say about this earbud, please read below.


  • Best-in-class noise reduction
  • Transparency mode is easy to use and easy to use
  • good sound quality


  • Does not support wireless charging
  • Does not support dual device connection and fast switching
  • Slightly higher price

The first impression after unpacking is that it is a little smaller than the previous generation. The charging case is 40% smaller than the first generation; the volume of a single earbud is also reduced by about one-third, making the ear less burdensome. The Noise Cancelling Earbuds II also feature the new Fit Kit stabilizing ring, available in three sizes, to keep the earbuds stable in your ears. Silicone earbuds are also available in three sizes to choose from. The combination of the two ensures a secure and tight fit.

Combined with the new “wearing test” in the Bose Music App, it’s easy to detect whether the correct size of the stabilizing ring and earplugs is selected to ensure optimal noise cancellation and listening.

Friends who have used Bose headphone products should know that every time you wear them, the headphones will emit a special “Weng” sound effect, telling you that the connection has been successful. On the noise-cancelling earbuds II, there is CustomTune intelligent in-ear sound field adjustment technology behind this sound effect. The technology will be automatically turned on every time the user takes out and wears the earphone, the built-in microphone will measure the sound effect of the ear canal, and the earphone will then accurately customize the user’s exclusive hearing effect and noise canceling experience according to the measurement result. The process is only 0.5 seconds, but it is useful in actual use.

At the same time, in the transparent mode, ActiveSense noise dynamic sensing technology can provide customized noise cancellation effects suitable for the user’s personal hearing experience, starting noise cancellation immediately when the noise occurs, and automatically stops when the noise ends.

Speaking of noise-cancelling listening experience, the Bose QuietComfort Noise Cancelling Earbuds II offer excellent noise reduction. When the author was writing the review, other colleagues in the office were having a video conference. After switching to the noise canceling mode, and then playing the focused music, the interference of the speaking voice was almost invisible. When shopping, all kinds of noise from passing vehicles are well suppressed; when taking a taxi or subway, background noise is also well eliminated.

Compared with the Apple AirPods Pro generation that I use every day, the noise reduction effect of the QuietComfort Noise Cancelling Earbuds II can be said to be a complete victory.

The Bose Music App provides a variety of customizable modes, including commuting, home, running, work, exercise, etc. Each mode can customize the noise cancellation level, which is very convenient. By the way, when one earbud is removed, the other is automatically lowered to the minimum noise cancellation level, which is suitable for certain scenarios. Of course, the transparent mode of the earbuds is also very good. After switching, you can clearly hear the surrounding human voice or the announcement of the airport station.

When listening to music, you can adjust the equalizer through the app, there are 4 preset effects, or you can drag the curve to adjust. In such a small body, Bose can provide a listening experience no less than headphones, which is commendable. The fly in the ointment is that the new earbuds do not support dual-device connection and quick switching. If you need to frequently switch audio between your phone and computer (such as frequent calls and video conferences), it may be a little troublesome.

The earbuds feature Bluetooth 5.3 connectivity, IPX4 sweat and water resistance, and support for voice assistants built into mobile devices. These are all conventional items, which are not unreasonable on this level of products, and of course they are better.

In terms of battery life, the QuietComfort Noise Cancelling Earbuds II have a 6-hour battery life, and the charging case can provide three additional full-charge support, charging the product within 1 hour. In addition, 20 minutes of fast charging can fully charge the power for 2 hours. The charging case can be fully charged in 3 hours via USB-C. It is a pity that the original wireless charging supported by the first generation has been cancelled on the new product, perhaps because of the manufacturer’s consideration to make the charging box lighter.

The Bose QuietComfort Noise Cancelling Earbuds II are probably the best noise cancelling earbuds you can buy right now. In daily use, it is smaller and more portable than headphones, and has excellent noise reduction. Personally, the only thing you really need to care about is the price. The price of 2299 yuan is not cheap, and there are many optional products on the market at the same level. If you are a user of brand ecology such as Apple, Samsung, Huawei, etc., maybe the headset of the corresponding brand is still your first choice. However, you can get a better noise-cancelling experience for a little more cost.

Depends what you want.
