OK, so I am new to the forum and I needed some expert advice. I wanted to buy a pair of headphones. Initially I wanted to buy Beats because they looked good but it's a big Nono now because they don't sound that great and I only pay for the brand and not the quality, and they are a rip-off. Now, I wanted you to suggest some of the best pairs of over-ear (possibly), but more importantly noise-isolating headphones. If you can please also write the online (Amazon, eBay, etc.) price. Preferrably the headphones should be available online. I don't want them to be TOO expensive, I guess $300 is enough for a good pair of headphones right? Maybe someone from the forum is selling them, that would be good as well (if, well, I can trust people from this forum). Thanks in advance guys.
