Build: decent quality, well built nothing much to complain about or to give praise to.

Earpads can really heat up your ear due to closed architecture. Made me sweat a lot.

The HD380 were the first headphones that made me feel like to much clarity is not good. It was my first try with a closed circumaural model and I had a pretty hard time getting used to how enveloping the sound is. I usually use headphones at work. So I need to focus on multiple things. But this headphones simply don;t allow you that. The sound is so realistic and so precisely transited to you ear (and skull) trough the direct contact to the earpad that it really envelops you.

Great headphones for am immersive experience.

But for me it was a bit freaky. The sound isolation is very good and the detail is high... very high. To high for me.

But in the end I sold them and am using now Grados. I prefer to have my ears getting some air and not heating up so much. The sound is also more natural. Or at least that's how I perceive it.

Conclusion: great analytic headphones for immersive experience. But I wills till go with a pair of Grados for now.
