Maximum Usable Volume (4.30)
What we found:
The DT 770s were capable of outputting about 96.07 decibels. This isn't particularly loud, but should be loud enough for most users. We award max points (10.00) for 120dB output; any louder than that and you'll hurt your ears. You should note that the DT 770s are capable of decibel output exceeding 96.07dB, but the playback will have over 3% distortion.
What is maximum usable volume?
Maximum usable volume refers to the most volume we can squeeze out of a pair of headphones before its distortion reaches a noticeable 3%. An increase in volume will also increase distortion, although the amount of increase varies between headphones.
How the test works:
For this test, we essentially perform a series of distortion tests. link.
Isolation (4.93)
What we found:
The DT 770s had average isolation levels for a pair of closed-back over-ears. Like other headphones that lack active noise cancellation, the DT 770s can more successfully block out higher frequencies, while the bassier frequencies will make it through unscathed.
The DT 770s will be better for a morning commute, but if you want decent isolation you should look for a set of in-ears or active noise cancellers.
How the Beyerdynamic DT 770 compares:
What is isolation?
Headphones that isolate well will block out a great deal of external noise. Isolation is a feature that has varying importance depending on use. Headphones that isolate well are useful during a bus or train commute, but significantly less useful for listening at home.
How the test works:
To test isolation, we blast HATS with noise, then strap the headphones on HATS and blast it again. Now that we have these two points, we can link.
Leakage (2.90)
What we found:
The DT 770s leaked a bit more than we would've expected. You shouldn't depend on them to totally isolate others from your music. If you're in the library and listening to your music quietly, those around you might hear a bit of a whisper. If you play it loudly, your music will likely be audible.
What is leakage?
Leakage refers to the amount of audio that spills out of your headphones to annoy those around you. If you're just listening to your headphones around your home, leakage won't be a giant issue. If you want to bring headphones to a museum, or want to watch an action movie without waking up your room mate, controlling leakage is more important.
How the test works:
To test leakage, we play some noise through the headphones. We have a microphone set up a few inches away to capture any audible output.
