Pro Reference quality sound which can be fun to listen to
Sound signature is fairly neutral, with slight elevations to the bass, mids and highs.
Bass has a nice fullness to it, with some extra depth which gives the sound a lot of body.
The mids are neutral but slightly forward, making the vocals sound really clear. Aggressive guitars can sound a bit harsh because of this though.
Treble has good extension, and the added peak on the highest frequencies add more sparkle to the sound.
Overall, these headphones can be used both for critical listening and for casual music enjoyment as well.
Pro Superb sound isolation
The closed back, over the ear design blocks out a significant amount of noise, allowing users to easily focus on the audio. Sound leak is also kept to a minimum.
These are great for tracking and monitoring, and are also great choices for use in quiet environments like a library.
Pro Headphone cable is detachable
You can easily remove the cable when these are not in use, making them easy to store. This also makes the cable easy to replace when needed.
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 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).
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 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 Comes bundled with a small pouch
The pouch will make it much easier to bring the headphones and its accessories on the go.
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.
Con Build quality is rather poor
The overall build is quite plasticky, with a lot of rattles. While it is not fragile by any means, the build quality certainly does not inspire confidence.
Con Ear pads are not the most comfortable
Pleather is used on the surface of the ear pads which traps heat and can make the area around the ears warm up fast. Also, while the ear pads are large and soft, they are also quite thin. People with larger ears may experience their ears rubbing against the driver housing, which can get quite uncomfortable.
Con Thin headband padding
There is minimal cushioning on the headband, so the plastic may dig into your head when using the headphones for long periods.
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.
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.
