In this day and age, everyone is linked to everyone all the time and we are so dependent on that connectivity that we will do everything in our power to be like that. That connectivity can be through tweets, text or phone calls, you name it. But still, this many means of connectivity were not enough for us.

We talk to our speakers, watches and our phones but we thought that we can take it further than that, so we started talking to our headphones. That was the thinking behind these new headphones, the Bose QuietComfort 35II’s, which are the successors to the original QC 35’s that came out in 2016.

These QC 35II’s have a unique new feature that sets it apart from the previous versions and that is the dedicated assistant button which can be programmed to work with any mobile device running iOS or Android. Add that to the perfect noise cancellation capabilities and amazing audio quality, and you have an amazing pair of headphones.


Bose QuietComfort 35II accessories

Starting with the design, the Bose Quiet Comfort 35II’s look exactly like the previous generation. The only difference is that fancy new assistant button located on that left earcup. There are two color options for you: Black and Silver.

There is not much change in the design and that’s why they are so rigidly popular with modest business class travelers and not for people who want their accessories to make an impression.

The plastic body is a tad bit disappointing, which is perfect to save weight but actually feels very cheap when compared to luxury headphones from other competitors.

Still, that plastic is very durable, and it doesn’t put a damper on the headphone’s ability to take punishment. The durability also extends to its bendability when you cram it into its travel pouch that is also included in the box.

Although this plastic doesn’t feel as nice as metal, it redeemed itself when long-distance travelers put it to the test and 9/10 preferred them over metal builds because of their lightweight.

The best thing about these headphones is the amazing battery life (about 25 hours) coupled with incredible noise cancellation that it retained from its previous generation.

The pads Bose use in these headphones are incredible, as they block out a huge amount of ambient noise even if the noise cancellation feature is turned off.

The crown jewel of these headphones is that new button and if you don’t know what an Assistant is then here’s a crash course. Assistant is Google’s equivalent to the likes of Apple’s Siri and Amazon’s Alexa.

Once you get set up with Bose’s Connect app or its equivalent in the Apple Store, the Bose Quiet Comfort will chime whenever you get a notification of any sort and it will automatically read out upcoming calendar events, which is always amazingly helpful.

Upon receiving a text or any other sort message from any social media app, press the button on the left housing which will read your message aloud and you won’t have to rummage through your stuff to find your phone or mobile device.

The amazing thing is that you can even dictate your reply straight after listening to the text using your voice and with Bose’s incredible microphones, it’s pretty easy to do so without any dictation errors. This dictation feature is mighty handy in the winters when you are out and have to text someone in the freezing cold.

However, with every good thing in this world, there are limitations and these new headphones are no exception to that rule. These limitations are in the music streaming feature through the Assistant button.

While you can use Spotify to stream music on android devices as the Assistant is currently unable to play your offline music via Tidal or Deezer, you cannot even stream music on Spotify through the assistant feature at all.

While connecting to 2 devices, you won’t have to worry about any linking issues because the QC 35II’s can pair with two devices at once even if one is a laptop and a smartphone.

How to Circulate Link Feature in Bose Quiet Comfort 35II Headphones?

A slight app problem is circulating in this linking feature is, that if we activate the Google Assistant to read a notification on our smartphone, it also starts iTunes on our MacBook. It might be a software issue and will be resolved quickly but it’s still a bother.

Another problem with these headphones is that it won’t read out contact surnames. So, if you intend to buy these, start using nicknames for your contacts having the same surname or up your guessing game, because you probably will have to spend time working out who the message is from.

We imagine that Google or Android users will benefit more from this functionality than Apple users because the linkage between these headphones and the Android ecosystem just seems more seamless than with iOS.

If you are not interested in using the assistant feature then that button can be programmed to another feature which is cycling through the headphones’ three noise cancellation modes, Low, High or Off.

The noise cancellation of these cans is quite impressive but it’s not a big surprise because the QC series always delivers on this feature.

Bose has always been on top of the list of tuning out ambient noise or rumbles and that carries on with these headphones. The microphones, both inside and outside the headphones properly eliminate any and every irritating background noise that will disturb your content viewing.

Programming the Action button or Assistant button is not difficult at all and you can follow these simple steps to quickly program it to whatever feature you like.

Steps to program the Action button:

  • Open the Bose Connect app, and connect your headphones
  • In the top right corner of the app, tap the Gear icon (Settings) to enter the settings menu
  • In the Settings menu, select Action button
  • Select between Noise Cancelling, Google Assistant, or Amazon Alexa

Common Issues With Bose QuietComfort 35II Headphones

The issues that have surrounded this amazing product is a software update problem that came into view a few months ago.

Many of the users of these headphones reported that the firmware update (4.5.2) has decreased the effectiveness of the noise cancellation feature of the headphones, which is the whole reason for these headphones to be so popular.

This issue certainly gave the owners of these headphones a bit of a pause when they wanted to update the software of their headphones but thankfully not all of the headphones were affected by the software update.

Many of the affected users of this issue reported that there was apparently a mismatch between the reported firmware in the Bose’s official connect app and what the updated app reads. Because of this, many of the technical Guru’s on the internet suggested that it might be a filed update causing the issue. They were right.

So, it is recommended that if you ever fall into the same ditch many others fell into before you, then follow these simple steps and you might be able to remedy the situation.

  • Turn off the headphones
  • Plug the QC35 II into your wall charger for at least 5 seconds, then remove the cable
  • Connect the headphones to your computer via USB, and go herein a browser
  • Download and run the Bose Updater app on your computer
  • Update the headphones using your computer to the latest firmware manually

These steps may not solve your problem because it might require a slightly different solution but at least it will ensure that you are running the latest software/ firmware on your device via a calculated process which is more likely to succeed, just as it did for so many others before you.


The positive aspects associated with this amazing product are as followed:

  • Right off the bat, the Assistant button is the most appealing feature on these headphones that can toggle any Assistant either Google Assistant or Alexa. If you don’t want to call any assistant, then that button is also programmable to quickly change the noise cancellation settings.
  • Although these are wireless headphones, you can also use them in wired mode unlike some of the other wireless headphones.
  • The noise cancellation is an amazing feature of the Bose Quiet Comfort series which has not been compromised as the series has progressed over the years.
  • The build of these headphones quite excellent considering it’s a plastic build rather than metal. The plastic is lightweight and long use doesn’t hurt your ears. Also, the ear cups are properly shaped to provide you with a highly immersive experience.
  • The microphone on these headphones is amazing for phone calls and text dictation if you want to reply straight from your headphones.


Some cons that we found in our research for this product are discussed below,

  • A big problem with this product is that the battery isn’t replaceable and that’s a huge downside to buying these headphones because not everyone is an excellent user of technology and a replaceable battery is an option that should have been a part of this product.
  • These headphones also don’t have any auto play/pause feature.
  • Also, the Google Assistant feature doesn’t work on iOS devices and you have to program, the multi-function button on the right earcup to make Siri work with your device.
  • And lastly, the main purpose of any headphones is to listen through them and sadly the sound quality that these headphones produce is subpar because Bose spent more time stopping noise going into the earcups and less on producing sound out from them.
  • There is also no instant mute feature which is provided by so many of the competitors in the market nowadays.
  • Another slight issue with these headphones is that they appear cheap because of their plastic build and plain design.

Tips for Maximum Performance

To get the most optimal performance out of your headphones, follow these suggestions exactly:

  • While buying your headphones, make sure that they are the right fit for you because you don’t want your ears sticking out of them when you are pulling long listening sessions during a study session or a long flight. These headphones have a perfectly snug design, but you should still make sure that it is the right choice for you.
  • To make sure that it is the right fit, put on the headphones and slide the headband adjusters right to the point when both of the earcups are properly surrounding your ears.
  • Make sure that the cushions are around your ears not on them because that can strain your ears during long listening sessions.
  • Next, you should check the right and left markings on the earcups to ensure that the headphone positioning around your head is correct.
  • As you may know, many portable headphones and other audio devices have a bass-booster switch that can easily alter audio signals reaching your headphones. Your headphones have excellent audio technology that already delivers a complete array of sound, so there is no need for a bass- boost switch on them.
  • For long-lasting battery life, you should turn off the power button on the right earcup when you are done listening to the content on your headphone.


That marks the end to our Bose QuietComfort 35II Review, and our verdict is that these are the best pair of headphones on the market right now if you really hate other people. Confused? The explanation is in the name of the thing “Quiet”. These headphones are mighty quiet.

Bose, as it turns out, perfected noise cancellation and built a headphone around it because at some instances it does feel like that, they have compromised on sound quality while favoring the ANC (Active Noise Cancellation) feature.

 what we think about them

Also, the newly added feature of calling up Google Assistant or Alexa doesn’t go unnoticed in day to day use and when you combine that with the already class-leading cancellation Bose is known for, you get an amazing pair of headphones. And that’s saying something considering how diverse the market is right now.

The Google Assistant feature works amazingly well on either Android or iOS but still no direct Siri support for Apple devices. Still, this feature gives a similar experience to the users as a Google Home does. The headphones reading back your notifications feature is also a big hit and a welcome mat for non-smart watch users because they might be new to that experience.

Although Google Assistant feature is an amazing feature to have but it shouldn’t be the absolute reason for you to buy this headphone.

Through its plastic build, Bose has not gained much popularity with people who want to make a statement with their accessories. But they have gained many followers in the mainstream market or normal people where people just want their headphones to be just headphones with some additional features.

So, all in all, the Bose QuietComfort 35II is an excellent headphone for people that use their headphones for longer period of times and want to cancel out all the ambient noise around them when they are in public places. Choose wisely.
