Pros
Pro Full and warm sound despite the small size
The drivers may be small and thin, but there is good bass presence.. The mid-range may not be the most detailed, but there is a smoothness to it that gives the sound a warm and pleasing quality. There is a slight roll-off to the high frequencies yet detail and extension is still good . Overall, these headphones can give a fun listening experience that can work well with all genres of music.
Pro Lifetime warranty
Koss provides a lifetime warranty for these headphones.
Pro Can be folded down to a very compact size
The ear cups can be folded into the headband. This further reduces its already slim design into something that is much more compact. When folded down, these headphones can easily fit in small bags.
Pro Can accommodate a wide range of head sizes
The headband can easily be adjusted to fit a user's head. The assembly features sliding metal pieces which can easily be set to fit small to large heads.
Pro ComfortZone system allows extra fit customization
Aside from headband adjustment, users can also adjust the clamping force of the ear cups using the Comfort Zone system. This changes how secure the ear cups attach to the headband, which results in either a loose or tight clamp.
Pro Can turn heads due to their retro design
These are eye-catching headphones because of their retro design. The unusual shape of the driver case and the blue accents definitely make these look unique.
Pro Has a durable and reliable feel
These headphones may look thin and flimsy, but are actually much more durable than their look suggests. The headband is made out of metal and can take some flex without snapping. The plastics used also exude a quality feel.
Pro Carrying pouch makes these easy to travel with
When used on the go, these headphones get extra protection from the included carrying pouch. This pouch looks simple and is made out of pleather, which should protect these headphones from scratches.
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 Danger for hair
Hair tends to get snagged on the metal headband which can get quite uncomfortable.
Con Not much power to the sound
If you are looking for headphones that offer a lot of thump and a lot of detail then these are not for you. The headphone drivers are too small for big and detail-rich sound.
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.
