Ranked in these QuestionsQuestion Ranking
Pro Companion smartphone app offers extra functionality
Sennheiser offers the CapTune smartphone app which allows users to see the battery level of the headphones, adjust the headphones' EQ, and control other functions.
Pro Carrying case gives headphones extra travel protection
The case is made from a tough fabric material which should protect the headphones from minor bumps and scratches.
Pro Can fold down for easier travel
You can twist the ear cups and then fold them into the headband for a smaller, more travel friendly size. In this state, it should take up a lot less space inside your bag for less hassle when used on the go.
Pro Comfortable to wear for long periods
Soft foam and leather are used in the interior and exterior of the ear pads respectively which makes them feel really soft and smooth on the head. The same material choices can be found in the headband.
Pro Powerful bass with good detail on the mids and highs
The sound tuning of these headphones is focused on the lower frequencies. The bass is quite powerful with good sub-bass extension. Users who listen to a lot of hip-hop, dance and bass-heavy music will certainly enjoy the oomph that these headphones can give. The mids sound natural and smooth, yet the lower regions of these frequencies can be overwhelmed by the powerful bass. The highs are crisp and clear though, which prevents the sound from getting too muddy.
Pro Headphones automatically pause/play when put on/removed
The Smart Pause feature detects if you are removing or putting on your headphones. These gestures will trigger the music to pause or play automatically.
Pro Right ear cup functions as remote
When in wireless mode, you do not need to use buttons in order to control the functions of the headphones. The right ear cup lets you control the headphones through touch gestures. You can swipe left or right for next or previous track, swipe up or down to increase or decrease the volume or tap on the ear cup to pause or play track as well as answer or end calls.
Pro Noise cancelling levels can be adjusted
You can set just how much noise is cancelled by the headphones, from maximum active noise cancelling, to an ambient mode which allows some sound into the headphones. You can also turn the feature off entirely.
Pro Effective noise cancelling
The feature works really well in preventing outside noise from intruding into your music listening experience. Also, there are very little to no reports of a feeling of pressure in the ears when the feature is active.
Pro Great passive noise isolation
These headphones are quite effective at preventing sound leakage, and also passively block out noise really well. This is achieved by the closed ear cup design along with the effective seal from the leather-surfaced ear pads.
Pro Great sound performance, effective noise cancelling, long battery life and Google Assistant smart features in a compact package
Most full-sized, wireless over the ear headphones are quite heavy and bulky. The QC 35 IIs on the other hand are relatively compact and light, yet still deliver great performance, battery life and top notch noise cancelling.
The integration of Google Assistant is also a first in headphones, and gives you a host of smart features like notification reading, quick music searches and call making using voice commands and many more.
Pro Great active noise cancelling
Bose's noise cancelling tech is quite effective at blocking ambient noise. This will help you fully enjoy the music by virtually eliminating outside noise.
Pro Fairly balanced sound signature with slight boosts to the mids and highs
Bass is full and punchy. While the sub-bass is not pronounced, there is good and fast bass extension, and this is what gives the music punch and a sense of tightness.
The mids are full and slightly forward so vocals and guitars can be clearly heard.
The highs are clear and do not distort at high volumes. There is a peak on the upper treble which helps to add more detail and clarity to the music, but some may also find the high frequencies to be quite harsh at times.
Pro Very good Google Assistant integration
These headphones are much more convenient to use and functional thanks to the Google Assistant upgrade. Press the long, flat button on the left ear cup to activate the feature, and you’ll be able to make voice commands to search for music, start calls, set reminders, get weather updates and many other features. This addition makes the QC 35 II one of the best travelling headphones you can get today.
Pro Has wired and Bluetooth connectivity
Aside from Bluetooth connection, you can also connect the QuietComfort 35 II to a source using a 3.5mm cable. This makes the headphones usable even with the battery depleted.

You can easily control playlist functions using the buttons on the right ear cup. These functions include volume control as well as the play, pause, next track and previous track commands. The on/off switch for the headphones is also on this ear cup.
Pro Very good battery life
The QC35 IIs can play music continuously for up to 20 hours. This should cover most of your trips' duration before needing to recharge.
Pro Mic produces great voice quality
Multiple microphones are strategically located on both ear cups, allowing for great voice quality when taking calls. The noise cancelling also helps to clean up the voice quality that goes into the headphones.
Pro Built in mic allows hands-free calls
You can simply press a button on the right ear-cup to answer a call. This reduces the hassle of having to remove the headphones to take a call.
Pro Not straining on the head/neck
Despite having internal batteries, these headphones are still fairly lightweight, coming in at under 300 grams. This makes the headphones really easy to wear for extended periods, even when you are on the go.
Pro Feels soft and comfortable
The QC 35 II's ear cups and headband feature quality memory foam material which are soft and supportive so they do not pinch on your ears or apply too much pressure to the top of the head. These contact points are also covered with a quality leather material which feels nice and smooth on the skin.
Pro Great for on the go use as they are wireless
With these, you won't have to deal with long and dangling cables that can be difficult to manage.
Con Gesture tracking can be too sensitive
Simply brushing your finger onto the right ear cup can trigger a command for the headphones. This can be annoying for some people.
