I blew a speaker on my HD595′s a few days ago, so I needed something new. I was going to go with another set of 595′s, but then decided to go a step further and get the HD650, Sennheiser’s top of the line audiophile headphone.
I got the package yesterday afternoon and tested them out right away, first just playing some music to make sure they worked and see how they felt on my head. Everything sounded good, wasn’t too much difference from the 595′s at first. They felt very comfortable, the headband and earpads are thickly padded. They were tighter than I thought they would be, but still very comfortable, after wearing them for a few minutes you can barely tell you are wearing them, which is great when you wear something for hours at a stretch.
While listening to music, (just some crappy low quality mp3s) there wasn’t too much between the 595′s and 650′s. When I started up TF2 though, the difference was huge. The 650′s sounded brilliant, everything was more crisp, clean, and natural sounding. The sounds of weapons firing was deeper and more distinct, it took me a little bit to get used to the new sounds, but once I did it was amazing how clear everything was. I could hear every shot, every taunt, every sound all over the map very clearly. I could practically hear the RED teams taunts when they came out of spawn while I was on BLU.
I am extremely pleased with these headphones, and would recommend them to anyone willing to spend the money. They are very expensive, but they are worth it if you want quality sound. I spend all day on a computer, and most of the time I have headphones on, so I need quality sound and a comfortable build, and the Sennheiser HD650′s definitely deliver that.
And no, they don’t have a built-in mic. Unlike Guntizzle, I like to actually use my headphones for other things besides gaming. A $5 Zalman clip-on mic works just as well as a mic on gaming headsets, and you don’t look like an idiot if you want to wear them outside.
In the HD 650, audiophiles will experience truly unique natural sound. With sound this good, long concerts in the comfort of your home are a certainty, so the HD 650 also sets standards in comfort and convenience. The HD 650 is a genuine masterpiece, which will satisfy even the most demanding listener. HD 650 – the Reference Class..
