In short

Hold on to a working QC35 II, but think twice before buying one now: it charges over micro-USB, runs 20 hours wireless and has no Aware Mode. Its Action button calls up Google Assistant or Alexa or changes noise cancelling, and with the audio cable connected it runs up to 40 hours. The QC45 that replaced it adds USB-C, Aware Mode and 24 hours of battery.

Who it is for

  • Owners of a pair that still holds a charge: 20 hours wireless covers a long day of listening.
  • Google Assistant and Alexa users who want a button for it. The Action button on the left cup calls up either one, or cycles noise cancelling instead.
  • Listeners who often plug in. With the audio cable connected it runs up to 40 hours, and you can keep listening over the cable if the battery runs out.

Who should skip it

  • Anyone tired of micro-USB. The QC35 II charges over USB Micro-B; USB-C arrived with the QC45.
  • People who want to hear the room without taking the headphones off. Aware Mode arrived with the QC45.
  • Listeners after Bose's newest features, from Immersive Audio and CustomTune to aptX Adaptive; those live on the Ultra models.

What sets it apart

  • The Action button on the left cup: Google Assistant on eligible Android phones, Amazon Alexa through Bose Connect, or noise-cancelling control, one job at a time. In 2017 Bose called it the first headphone with seamless Google Assistant access.
  • Up to 20 hours wireless, or up to 40 hours with the audio cable connected.
  • Two devices active at once and up to 8 remembered: music plays from one at a time, and calls ring through from both.
  • NFC tap-to-pair on top of Bluetooth 4.1.

Caveats

  • It won't play while it's charging.
  • Google Assistant works only on eligible Android phones, and only in some regions.

Where the QC35 II stands now

The QC35 II went on sale on 21 September 2017 at $349.95, the same price as the original QC35 from 2016, and Bose sold it until 2022. It kept the first model’s noise cancelling, sound and 20-hour battery and added the Action button. The QC45 replaced it as Bose’s numbered QuietComfort, with USB-C, Aware Mode, Bluetooth 5.1 and a 24-hour rating, and later models go further: the QuietComfort Headphones and the Ultra line, which adds Immersive Audio, CustomTune and aptX Adaptive.

If yours works, there’s no hurry to replace it, and a cable keeps it playing when the battery gives out. If you’re buying used, though, a QC45 fixes the two daily annoyances here, the micro-USB port and the lack of an Aware Mode, so price the two against each other.

Noise cancelling and the buttons

High is the strongest noise-cancelling setting, the one Bose calls world-class, and you can step through the levels with the Action button or in Bose Connect. There’s no Aware Mode for hearing your surroundings with the headphones on.

The Action button holds one job at a time, so if you give it to Google Assistant or Alexa, you change noise cancelling in the Bose Connect app instead.

Battery, charging and the cable

ModeQC35 II
WirelessUp to 20 hours
With the audio cableUp to 40 hours
Full chargeUp to 2 hours (owner’s guide); 2.25 hours (Bose support)

It charges over a micro-USB port on the right earcup, at 5V DC and 1A. Keep the 2.5 mm to 3.5 mm cable from the box: the 40-hour rating depends on it.

Bluetooth and range

The QC35 II runs Bluetooth 4.1 with NFC tap-to-pair. Bose’s support specs give a range of up to 33 feet (10 meters); the owner’s guide says 30 feet (9 meters). The profiles are A2DP, AVRCP, HFP, HSP and BLE, and Bose lists no codecs for it.

Folding and the case

It folds flat into the carry case that comes with it, and the box adds a USB charging cable and the audio cable. It launched in Black and Silver.

Price

The QC35 II launched at $349.95 and is only sold used now. A used QC45 is the obvious alternative, so compare the two before you buy.

Frequently asked questions

Is the QC35 II the same as the original QC35?

No. The QC35 II, from 2017, added the Action button for Google Assistant, Alexa or noise control. Bose kept the 2016 QC35's noise cancelling, sound, 20-hour battery and $349.95 price.

Should I upgrade to the QC45?

Yes, if you want USB-C charging, Aware Mode or more battery: the QC45 has all three, with 24 hours on Bluetooth 5.1 and the Bose Music app. If your QC35 II still lasts the day and micro-USB doesn't bother you, keep it.

Does it work with Siri?

Yes. The multi-function button on the right cup reaches Siri; the Action button handles Google Assistant or Alexa.

Does it use the Bose Music app?

No. It uses Bose Connect, which handles pairing, noise-cancelling levels, the Action button and firmware updates. Bose Music arrived with the QC45.

Does it fold?

Yes. Rotate both earcups inward so they lie flat, fold the left cup up toward the headband and lay the headphones in the carry case.
