Heya,
I had them.
I found them uncomfortable. The pads got sweaty really fast and so the headphone moved around a lot due to that so it made it very difficult to enjoy them while walking/driving with my window down. They just felt like they were going to snap, they felt brittle. Beyond that, they actually sounded quite good across the board. Good highs, good mids and some very decent bass frequency response. When amped they jumped quite a bit even though they don't need an amp. They're basically a $50 headphone at most stores online. Getting it for $30 is a good deal. I'd have kept them for $30 simply as a `back up' headphone perhaps. But ultimately I sent mine back to Amazon because I simply cannot wear something uncomfortable. I was using it as a portable headphone primarily (closed back to avoid leakage in while driving around and walking and sharing the music so to speak). I have to have cloth pads. Every single phone I have is cloth padded. Anyhow, had they not been so uncomfortable to wear I probably would have kept them in the collection. But again, for $30, they're a good headphone for someone--just not for me unfortunately. Again, they actually do have pretty good sound.
Very best,
