Frequency Response (4.21)
What we found:
The DT 770s had an average frequency response. On our tests, we saw a good bass response that remains strong up until about the 4kHz mark. There's a bit of a dip at this point. The response is emphasized again from about 7kHz to 10kHz before dropping down again.
The boost in 7-10kHz should give drums a strong attack. Any instrument spanning the 4kHz range might sound a bit odd because of the 10dB drop.

What is frequency response?
Each set of headphones puts a different amount of emphasis on the frequencies they produce. Reference headphones try to not put any, while dynamic headphones tweak the sound in various ways in order to create a subjectively ideal sound.
How the test works:
We test frequency response by playing a frequency sweep through the headphones. HATS, our wonderful listening robot, notes the output, which we then compare back to the source sound. Just like that, we've analyzed the headphones' frequency response for you, our internet readership. For more info, here is a link.
Distortion (10.90)
What we found:
On our test, the DT 770s barely registered any distortion. These headphones should be great for audiophiles.
How the Beyerdynamic DT 770 compares:
What is distortion?
Distortion changes the way your music sounds. If you're a big fan of music that already employs a lot of distortion filters, this section is probably unimportant to you. If you listen to acoustic music and spit take every time you hear an off note, distortion will likely be more of an issue.
How the test works:
Similar to the previous test, we use the magic powers of subtraction to arrive at a result. We play our test sound through the headphones and record their output with HATS. We then compare the initial soundwave to whatever the headphones output and we can figure out exactly what's getting distorted and by how much. To find out more about this magical process, read this page.
Tracking (4.76)
What we found:
The DT 770s didn't do that well on our tracking test. They started out slightly louder in the right channel, then the volume emphasis slowly shifted to the left channel. After this, the headphones are balanced for a stretch, but run into some issues just after the 2kHz mark. The volume shifts slightly to the right channel, then jumps to the left in a 9dB shift. This is loud enough to notice. After this point the tracking remains a bit erratic, but the shifts aren't particularly noticeable.
How the Beyerdynamic DT 770 compares:
What is tracking?
Headphones with good tracking will be able to output roughly equal volumes from both their left and right channels. If a headphone has bad tracking, one channel will consistently sound louder when playing back a specific frequency range. The more disproportionately loud one channel is, the worse the headphones are.
How the test works:
This test focuses on relative volume differences, so frequency response has no bearing here. The headphones could totally blow out bass, but as long as it's blowing it out evenly on the left and right, they'll have fine tracking. To test tracking, we play back our test sound file, then have HATS measure the volume output of each channel separately. If one is louder than the other, you'll see the graph above spike or dip. When the line raises above zero, the left channel is louder. When the blue line dips below zero, the right channel is louder. For more info, read the stuff in this link.
