Specs
Ranked in these QuestionsQuestion Ranking
Pros
Pro Impressive isolation and minimal sound leakage
These Beyerdynamics offer impressive sound isolation, keeping exterior noise out and your music in.
Pro Sits well over your ears
The DT770s are very comfortable to wear with deep and spacious ear pads. The velour material used on these are smooth and breathable, and the thick foam provides ample cushioning. These headphones can be worn for long periods of time with ease.
Pro Good soundstage for closed back headphones
The DT770 Pro, when amped properly, creates an open feeling sound stage that is very impressive for a headphone with a closed design.
Pro Great sound quality with deep and powerful bass
The bass is not overpowering. Instead, it is clean and controlled. The overall sound signature is focused on the bass but the mids and highs are in no way lacking either.
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.
Cons
Con May require extra power/amplification for optimal sound
Depending on which model is purchased (16/80/250-ohm), your system may have trouble powering them to get a full sound and comfortable volume. 16/80-ohm should work fine in most systems. If not, you may need an external amplifier.
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.
