Pros
Pro Best in class noise-cancelling
These headphones are ideal for long flights. In addition to having overall impressive noise-cancelling (-33dB across all frequencies on some tests), these headphones excel when you need to cancel out low frequencies like jet engine sounds (-45dB).
Pro Comfortable
The headphones stay comfortably in your ear. They don't always offer a complete seal but surprisingly, this doesn't affect noise cancellation or reduce comfort. Also included are 3 sizes of eartips to help better fit your ear. Note that these tips have a unique design so you won't be able to use aftermarket tips.
Pro Cord doesn't tangle easily
These headphones have a 2.5 ft cord that's split chest high with a control module near the jack. It does a good job of not getting too tangled.
Pro Comes bundled with a small pouch
The pouch will make it much easier to bring the headphones and its accessories on the go.
Pro Disable noise-cancelling with "Aware Mode"
You can disable active noise canceling at a press of a button. Aware Mode can be quickly accessed from the remote, which will disable active noise-cancelling and open up the microphones to allow you to hear your surroundings better.
LEDs on the control module will let you know when this mode is turned on.
Pro 16-hour battery
These QC20 has a lithium-ion battery that promises to work for 500 charge cycles without diminished returns. After that it will still work, but won't last as long.
Note that the battery is non-replaceable so when it finally does stop working, you will need to buy a new pair of headphones.
Pro Effective noise cancelling
Bose's noise cancelling tech is quite effective at blocking ambient noise. This will help you fully enjoy the music with little to virtually no outside noise interfering.
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.
Pro Very good battery life
The QC35s can play music continuously for up to 20 hours. This should cover most of your trips' duration before needing to recharge.
Pro Connects to multiple devices
Bose QC35 connects to 2 devices (for media and phone calls) allowing one to listen to music on the laptop and get calls from the cell phone. Allows to change the music provider (laptop or cell phone) automatically. With Sony or Senheiser all you can do is connect media on one device and phone on the other device... functional but really restricted one you get used with QC35.
Pro Feels soft and comfortable
The QC 35'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 Light and easy to wear
Despite having internal batteries, these headphones are still fairly lightweight, coming in at 235 grams. This makes the QC35 really easy to wear for extended periods and even while traveling.
Pro Ear cup buttons allow easy control
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 Has wired and Bluetooth connectivity
Aside from Bluetooth connection, you can also connect the QuietComfort 35 to a source using a 3.5mm cable. This makes the headphones usable even with the battery depleted.
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 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.
Cons
Con Expensive
The suggested retail price for these headphones is $300. And although you can get a pair on Amazon for around $200 it still is a lot to pay for a pair of earbuds.
Con Average sound
The sound of the in-ear headphones is decent. The highs are a bit withdrawn, but the sound doesn't come off as too muddy.
Con Noise cancelling may cause ear discomfort
Some experience a feeling of extra pressure into the ears when noise cancelling is on. Many find this to be unpleasant.
