I got these headphones in a package with my piano. I think the sound in them is great, however, they are not super comfortable for me. I can't wear them for long before they hurt my head and ears. I'd still recommend them for anyone who can't afford better, like they're good enough.
In terms of quality, you can feel that they are cheap but not super cheap. Personally, I'm not a huge fan of the material that the actual cups are made from.
But in short, I'd recommend them for anyone who can't get better or don't want to spend too much on headphones. Like, they're good for the price.
