The Beyerdynamic 770 Pro (80 ohm) offers a more immersive audio experience and better overall sound quality, with greater comfort and superior build. It's well-suited for dedicated listening sessions and provides good noise isolation, although it lacks a microphone for calls. On the other hand, the Koss KSC75 is more affordable, offers decent sound quality with an open design that doesn't isolate noise well, and is much lighter. Consider the 770 Pro if you prioritize sound quality and noise isolation over cost and portability, but if budget is a concern and you need something more compact, the KSC75 could serve well for casual listening.

"Altogether, when you consider its accessible price tag, the performance, the build, and its outstanding comfort, I think that the DT770 Pro is fantastic option for anyone looking for a closed-back headphone in the sub-$1,000 range, and I can confidently give it a strong recommendation."

"Let’s not insult the KSC75 by saying that it’s simply good for the price… because it’s far more than that. It basically has a monopoly at its asking price, and could still give modern budget headphones a run for their money 15 years after its release. The KSC75 is the world’s best not-headphone."
