A funny thing happened on my way to writing a one-star review...
23 July 2014
Summary: Some time ago my venerable HPA2PCs fell apart after nearly 5 years and I began shopping for a replacement. What I wanted was an upgrade to those,,,but I kept coming back to the originals as being the best. They are discontinued. After some research I decided to give these Senns a try.
Summary: To really review this product, I need to break it with 2 parts: The headphone - It is a decent headphone. I been using Sennheiser HD600, so both the sound quality and comfort level is nowhere near it. That's not to say this headphone is bad with this price point. It's still pretty comfortable for a few hours of wearing. However my ears are quite large (u can call me dumbo...) and I wear a pretty thick frame glasses.
Summary: In relation to other $75-$100 range headset, this one is right in the middle. To put it in to perspective, I compared this headset to the Logitech g930, Corsair Vengeance 2100, and the Steelseries Siberia V2. The quality of the of the headset was the only thing I was disappointed in. For me personally, I like a nice tight, solid built headset, which isn't hard to find with my larger head. This headset felt loose and flimsy.
Summary: The surround sound wasn't as gimmicky as I expected it to be, and the mic worked really well. Otherwise it was quite comfortable, my only other gripe was how flimsy the thing felt. Unfortunately the pair I got didn't work properly, the left driver didn't work very well and went out completely when I changed the volume. There may be better headsets out there for the price.
Summary: For reference I have a pair of HD-598's and 518's. These don't sound bad at all. For casual listening they are only a step below my other headphones. They have brighter highs, not nearly the warmth of the HD's. I would easily be pleased with these if I'd never tried the 598's. The brightness actually plays better with games, so that's a plus. What I have issue with, is the 7.1 (and 5.1) virtual surround are terrible.
Summary: Sennheiser has been the go-to brand for professional microphones for years; filmmakers, musicians, broadcasters, you name it. But I never realized they branched out into headsets for the home user, because I always associated their brand with the professional market. So I was interested to see how the Sennheiser brand translated to this type of gaming application.
High quality sound, well designed. Does hurt your ears after a while

Summary: High quality sound, well designed and made, easy to adjust and install. Very much like the volume control designed in the outside ear cup, very neat. Initially very comfortable and I would have given four stars but after consideration decided to only give three stars for the discomfort to my ears after wearing them for a length of time. I think the size of the ear cups should be larger to fit around the ears and not squashing them to the side of your head.
Summary: As of writing this, this headset costs £109 which in my opinion is way too much. The sound is OK. There's a lack of base. It just feels flat. It's a step up from just using speakers (except the lack of base; for explosions etc) as you can hear what's going on around you (7.1 ss), which is great, but I believe you can get a much cheaper product which will sound better.
