Summary: Sorry for no actual review as i have just got into audio recently and this is my first pair or good headphones. But even i could tell there was alot of sub bass not loud but its definitely noticeable.
Pros: Comfort, good detail for a closed headphone
Cons: Close sounding vocals, Sub bass maybe a bit too much for some, Undetachable cable, not very loud through phones
Excerpt: I am a drummer, and because I have a problem with earwax buildup, I wanted to stop using earplugs and IEMs. So, I was looking for some circumaural headphones which could serve the same purpose. A lot of typical earplugs claim noise attenuation of ~30 dB, and my Etymotic IEMs claim 35-40. The DT770M claims 35 dB, but unfortunately this doesn't work at all. They don't even come remotely close to isolating as well as even the cheapest foam earplugs, rendering them useless.
Cons: Poor isolation, Poor Sound Quality, Pricey / Poor Value
Excerpt: I am a music producer, studio audio engineer, audio for live events and I have the DT770 Beyerdynamic for many years, and are an excellent reference but for the live recordings I need an excellent reference but with good power. I thought the Beyerdynamic DT770-M would sound very similar to traditional DT770 but was very disappointing to hear, I had to change and invest more for an Ultrasone PRO 900
Excerpt: When I first took these out of the box, they sounded terrible and I was really wondering if I had just thrown my money away. I decided to give them the full treatment and I burned them in with a variety of music, hitting all the frequencies, soft for a day, then normal, then a bit loud, for a total of about 75 hours. After that I put them on and I was amazed at how good they sounded. As far as isolation goes, they seem quite good to me.
Summary: I am very happy with these headphones so far! I have cleaer sound from high to low and extra bass for electric drum set bass, is NOT an issue. With other headphones I did have some trouble seinheisser and NADY were, for the model I had not enough volume or range. Nady qh360 and Seinheisser HD210. I have no comlaints as of yet. I am sort of in shock regarding how something so small and light can pack so much range and power.
Summary: I purchased this headphone after I returned the Sennheiser HD 25-1 II.
I was not satisfied with the soundstage of the sennheiser, plus after an hour of wearing them my ears started to feel bruised.
The DT770 Pro does not have these downsides, the only downside is the siblance.
In a song with a lot of S's or maybe hard t's the headphone starts to whistle. If the volume is cranked up it the whistle actually hurts my ears.
Summary: The DT770 is a lower priced model of the Beyer line, but it is a boiled down version of the Beyer sound and one of the best values in closed headphones. While known for excellent bass response generally, you will also find them one of the most comfortable in the price range. The ear cups aren't as nice as the DT990 velour pads but they are comfortable. They do get sort of hot after wearing them for a long time.
Pros: Bass quantity and range, comfort for extended listening, easy to drive
Cons: Recessed mids mean it's not the best choice for some. Earpads lose their shape after time.
Summary: Directly compared:
Sony MDR-7509HD (my last headphones)
Sennheiser HD380 Pro
Beyerdynamic DT770 Pro-80
Beyerdynamic DT880 Pro

Tonal accuracy is very good. I am using as a reference my home theater with Sunfire XT ribbon hybrids and Bag End professional mastering subwoofers. The all important mid-high region is spot on. Bass is slightly emphasized, true, but the degree is exaggerated IMO.
Pros: Great tonal balance, imaging and isolation
Cons: Inefficient, slight bass emphasis, very long break-in required
Summary: These headphones are my first pair of high-end (probably mid-fi to some) cans and after a year or two of use, I have mixed feelings about them. When I first got them, of course they were a HUGE step up and I loved the bass from them, they were the perfect headphones to me. I was hearing sounds I had never heard before in music, hearing imperfections and low-quality sounds as well.
Summary: I'll preface my review with that I am not a seasoned audiophile, so I don't know all of the jargon, but I do appreciate good sound, and I like what I hear in these. They are by far the best sounding headphones I have ever listened to.
Granted my collection of headphones is very limited.
Pros: closed circumaural design, 80ohm design allows use on portables in a pinch, very comfortable
Cons: Eardrum-piercing sibilance prior to break in completion, break in is quite long
