Bose QuietComfort 35 II Review

The Bose QuietComfort 35 II is rightly one of the most popular noise-canceling headphones today. But unfortunately, noise-canceling that is still competitive, excellent wearing comfort, and a problem-free Bluetooth connection are no longer enough for the crown among ANC headphones. Still, the QuietComfort 35 II remains an absolute recommendation.

Bose is undoubtedly one of the pioneers of noise-canceling headphones, and the QuietComfort 35 II has continued that tradition. It has since been replaced by the QuietComfort 45 but is still commercially available in various versions.

You can see how the Bose QuietComfort 35 II performs compared to current noise-canceling headphones in our list of the best.


  • Very good fatigue-free sound
  • High output power
  • Very good seat
  • Lightweight
  • Intuitive operation


  • Bass is a bit too prominent
  • No sound control options

Bose QuietComfort 35 II -The sound

The QuietComfort 35 II sounds round and warm. Even if the detail resolution cannot keep up with the QC45 and the spatiality on Lars Danielsson’s record “Libera Me” (ACT) is represented more impressively by the Sennheiser PXC 550 II. For example, only a few other noise-canceling headphones achieve fatigue-free playback over long periods.

Round, deep bass, and a balanced mid-range ensure unadulterated listening pleasure – regardless of the music style and listening volume. Speaking of which, the QuietComfort 35 II can generate very high volumes without ever becoming painful.

Esbjörn Svensson’s piano on “The Goldhearted Miner” feels just as comfortable as Toni Braxton’s production “Secrets,” and even harder paces are unlimited fun. However, only the snare drum played with a brush in the jazz mentioned above piece by Esbjörn Svensson gives an idea of ​​the narrow-band dip around 3.5 kilohertz that can be seen in the frequency response and is reproduced with minimal damping.

On the other hand, it is precisely these frequencies that quickly tire the ear over time. And maybe this sink is partly responsible for the pleasant sound character of the headphones – one could therefore assume that the developers at Bose did it on purpose at this point.

The frequency peaks that can be seen in the treble range are around 4.5 and nine kilohertz and do not lead to aggressive hi-hats and cymbals in Toni Braxton’s “Come On Over Here .”Only Paul O’Brien’s “Misty Mountain” (Stockfish Records) S-sounds are emphasized slightly but without disturbing.

However, the bass range is a bit too strongly emphasized for our taste. In our opinion, a little less would have been more here. Nevertheless, given the sound quality, it is not surprising that the QuietComfort 35 II has such a triumphal procession behind it.

The technology of the QuietComfort 35 II

Compared to some competitors like the Sony WH-1000XM4 or the Apple AirPods Max, the QuietComfort 35 II is pretty conservative and does without spectacular material battles. Malicious tongues might call the design “old-fashioned,” but that didn’t stop Bose from adopting it for the QC45 virtually unchanged.

But appearances are deceptive, the headband and its attachments are made of solid metal, and the plastic of the ear cups is glass fiber reinforced. And the design is still extremely practical; the handset, which weighs only 235 grams, is extremely comfortable and stable on the head. In addition, the controls can be used intuitively and effectively – modern features such as touch control panels are hardly missing.

Design, quality, and wearing comfort

The QuietComfort 35 II are over-ear headphones that are extremely comfortable on the ear, never pinch, and have enough stability on the head. Even with prolonged use, there is hardly any heat build-up. The metal headband has a comfortable velour padding and is easy to adjust.

The ear cups are made of plastic, which certainly contributes to the pleasingly low weight. Moreover, since the material is glass fiber reinforced, as already mentioned, you hardly have to worry about long-term stability.

So don’t let the simple design fool you; in terms of wearing comfort, the Bose QuietComfort 35 II is certainly one of the best headphones on the market. The foldable device comes in a sturdy synthetic leather case, in which it is safely protected during transport. In this sub-score, there is practically nothing that the newer QuietComfort 45 could do better.

The QuietComfort 35 II in a practical test

The controls of the QuietComfort 35 II are spartan, the slide switch for operational readiness is on the right ear cup; on the underside, there are three large buttons next to the USB socket and an LED to display the battery charge level.

The top and bottom buttons control volume, while the middle button performs multiple functions:

  • A single click starts and stops playback and switches to phone mode.
  • A double click skips to the next track.
  • A triple-click skips to the previous track played.

Since the very large buttons also have a clearly defined pressure point, the operation is always simple and safe – we hardly made any operating errors in the test. There is only one large button on the left ear cup – and this is where one of the most important innovations compared to the previous model is hidden.

Previously, it was only used to switch between the different noise-canceling modes. Still, this button can now be configured via an app to activate voice control and control Amazon Alexa or Google Assistant.

In addition, the app offers access to various music streaming services and manages multiple Bluetooth devices. The noise-canceling can also be regulated in two intensity levels here, as well as completely deactivated.

Sound settings like those of other manufacturers or the Bose Headphones 700 are vain. That’s a pity – it would have been nice to have been able to reduce the comparatively prominent bass if necessary.

Test result for the QuietComfort 35 II

The Quietcomfort 35 II still impressively proves that its success did not come about by chance; the objective sound quality is very good; apart from the slightly too prominent bass, the sound pattern is unobtrusive and non-tiring. Moreover, its wearing comfort is still one of the market’s best, and its operation is always effortless and error-free. Unfortunately, however, the Bose QuietComfort can no longer quite keep up with the younger competition in terms of sound and ANC.

Which Bose headphones to buy – QC 35 II or QC45

In a direct comparison with the successor, it quickly becomes clear that Bose has significantly improved the QuietComfort 45 in many respects. It sounds even more balanced, is just as comfortable, and the ANC works even better. So the QC45 is the better headphone, but that doesn’t mean anything. If you’re looking for reliable and comfortable headphones for everyday use, and you can get the QuietComfort 35 II cheaply, you can’t go wrong.
