I graduated to these headphones from Sony MDR-7506 and never looked back. I’m on my second pair now and for 9, they are worth every single cent and more. These headphones completely engulf your ears and are very comfortable, it feels like two pillows resting against your head. I’m a programmer and I wear these babies all day long. What I really like about them is that you can blast your music and it doesn’t escape them so you don’t annoy the people around you. On the flip side, once you put them on you can’t hear ANYTHING from the outside world which is what I like too. As far as the music goes, pretty bassy and especially suited for rap and hard core techo music with a deep bass line. The pure highs are a bit lacking. But this is a bass head’s headphone and I love them. They’re also as strong as iron. I can throw them around the room, in my backpack, sleep with them. Hell throw them on the wall for no reason and they’re as good as new. The only cons I can think about is that they look pretty stupid when you put them on. They’re HUGE. But that’s the nice thing about being a programmer you can look as ridiculous as you want.

As a radio professional, I demand headphones that are going to give faithful sound reproduction with solid construction. You’re putting them on and taking them off every four minutes, and have a cord to walk around and try not to trip over for your other tasks. No matter how religious I’ve always been about being gentle with them, until I tried Beyer-Dymanics, every single pair I’ve ever owned has let me down within ten months. Either the wiring cuts out on an ear, and/or a studio mishap sends parts flying.

I’ve owned my DT770s for over five years. Best investment I’ve ever made, as headphones go.

For me headphones are a very personal sort of thing, so it’s hard to rate or recommend it to other people. For me I wanted something with a decent sound stage, good bass, and a comfortable fit. These headphones have that.

These cans have completely changed they way I listen to music, I find myself listening to more and more classical music because it just sounds flat out amazing with these headphones. Rock, metal, and jazz sound equally impressive but be prepared to delete songs as these phones will bring light to shed upon your puny bitrates.

All in all I have to say these phones earn the following (1-5 scale):

Sound Quality (4.8) There’s probably better out there but only if your willing to spend 00 for a speaker setup or 0 for headphones.

Sound Leakage (5) These headphones leak very little sound and also help block outside sounds (like plane engines) very well.

Comfort (5) With their valor earcups (just like the soft bosom of Zap Brannigan’s uniform) these headphones are comfortable enough to wear indefinitely! I also found the headband to be less invasive as on other headphones.

Portability (3) These headphones are a bit bulky and I’m not sure how they sound without an amp, I believe a ipod could give these enough juice to run, but I haven’t tried it yet.

Value (5) If you can find these for under 0 used or new, the purchase is a no brainer, these are a must buy if you can afford them!

Overall score: 4.5

These are amazing headphones, if you can find them for under 0 buy them immediately if you can’t then save up the extra cash and buy them anyway! Overall I am very impressed with them!

—UPDATE 2010—-

After well over a year of use, I have decided to move on to another pair of headphones. Despite all the problems I’ve had with these DT770s Beyerdynamic left such a positive impression on
me that my next pair will probably be the DT 880s.

The issue with the DT 770s seems to be that the right ear cup will develop a jarring rattling/vibrating sound when any low frequency sounds are played. I cleaned the headphones thoroughly and didn’t find any hair near the driver. More recently I discovered this was a common issue with the DT 770s and can often be attributed to the lower quality cabling or something wrong with the driver itself. Because of how common this issue is with the 770 line, I dropped my rating by 1 star (though I would have only dropped it by half if I could).

However I was so pleased by the performance and comfort of the DT 770s, that I have not been able to wear any other headphones, sure I thought the K701s sounded better, but that stupid headband and its painful bumps dug into my brain. I’ve become so spoiled by the construction, feel, and sound of the DT 770s, that I don’t think I can use any other headphones unless they use a similar design and velor earcups. These were the only headphones to ever fully cover my large head and elongated ears. So if anyone knows of any non-Beyerdynamic headphones that fit as well as these, let me know, because I have yet to find any!
