DT-770 Pro 80 Ohm : No wonder these are used in studios

This is pretty much a classic. I've had these for 5 years now and there's nothing wrong with them nor do I see anything going wrong with them in the forseeable humanity's future.

Sturdy as anything can get in today's world. You'd have to go out of your way to break them.

Sound is good, not really an audiophile but I think with proper push from dac/amp everything is there. Might be more on the bass side, but I feel that's really down to closed back design. They seem fairly balanced.

Comfort might be an issue. If you want headphones that cancel out everything around you, they do that. They do that very well. The problem is if you try to use these headphones for daily use behind PC as you main source of sound. Your head will feel pressed, hot and just a bit uncomfortable after hours of use. Do note, after hours of use which these headphones were not designed to. They are studio headphones and it shows.

It's all more for intermediate dips into music world rather than everyday workhorse that delivers everything for you. Still, really REALLY good headphones.
