I rarely used headphones for a long time, and then I was fortunate to have a great pair of Grado open-ears. Then, when I needed closed ears, I got the Sennheiser SD280 (I think that's the name). Anyway, eventually, for whatever reason, I needed a new cheap pair of closed-ear phones and I plumped for these.
The drop down in quality was shocking. Tinny, piercing, and the sound seemed ... distant. Anyway, I highly recommend saving up for better phones if you can. If you're absolutely stuck, I guess they're at least cheap and seem to be well built.
