I hear these are really good Newegg.com - SENNHEISER PC161 3.5mm Connector Circumaural Headset - Retail
I used to have the PC150 headset, but I accidentally broke off one the the earphones (after about 2 years of use), so right now I'm looking into getting the PC161. I don't like headphones that cover my whole ear, and these are extremely comfortable, and has a nice clear mic. I'm sure many would agree that Sennheiser makes really nice products. Just make sure you don't step on them like I did!
In my opinion I would go with the PC151 ot PC161 over the 465s, but that is just my preference in headphones.
