Biggest difference would be the closed vs. open back design. Open backs are awesome where convenience allows for it. Personally, I use open backs (HD6xx) when alone in my room, mostly for either casual or critical listening. I tend to use closed backs (DT 770) when commuting, at work and on the occasion I want to block out external noises.weight. 250g. 254g. We consider a lower weight better because lighter devices are more comfortable to carry. A lower weight is also an advantage for home appliances, as it makes transportation easier, and for many other types of products. has a detachable cable. Beyerdynamic DT 990 Pro. Sony WH-XB900N.
Also, the bass response is different, the 990 has a hump centered at about 100 Hz, so it is "punchier", while the 770 emphasizes mainly deeper bass ("thump") around 40-50 Hz. Of the two versions of the DT770 Pro, the 80 Ohm one is said to have more bass, while the 250 Ohm version (I only have that) is brighter. Quote:
The 770's are closed back and the 990's are open. This means that the 770's won't leak sound and you won't hear as much from your environment. The 990's leak (people around you will be able to hear every lyric of whatever you are listening to) and you hear everything around you unless you turn your music up.

The DT 770 has very precise imaging, but its soundstage isn't much different than other headphones. The DT 770 has somewhat boosted bass compared to the DT 880, but unlike the DT 990, the bass isn't at all boomy from the DT 770. The DT 770's bass is tight, deep and clean. The bass is solid to 27 Hz, and still audible at 16 Hz.The DT 880 is an improved version with semi-open earcups offering the most versatility. The DT 990 is the most updated version offering open-back ear-cups and minimal ambient noise reduction. The DT 880 is the most expensive, and the DT 770 is the cheapest.
