Bought these for leisure listening (I'm not a musician, "audiophile" or sound pro).
In the last 20 years, I had 3-4 Sennheiser HD202s that all ended in the same way - cable issues. So more than anything else, I wanted headphones with detachable STANDARD 3.5mm jack cable. I couldn't find any such in the wired-only headphones here on Thomann, they always come with annoying proprietary jacks on one end. So I got a Bluetooth one.
The sound is crisp, detailed in all frequencies. Somewhat lower bass volume than my previous pair of cheap bass-heavy headphones, but this seems normal for studio headphones. Haven't tested Bluetooth function yet - I use my own cable. Build quality is not stellar, but largely adequate for this price point. Comfortable, used it for up to 2-3 hours without issues. Better sound isolation than other headphones I've used. Overall, these are excellent.
