Summary: I heard a lot of people complaining about how comfortable these might be, but I`ve used them for some time now and I did not notice. The sound is excellent for this kind of price, both qualitatively and quantitatively. The bass is absolutely superb. The only better headphones I have are Roland, but they cost 150 euros.
Summary: I've purchased several of these headsets, over the last few months... and, simply by reading that first sentence, you can probably guess that it's NOT a very good headset. At first, it works like a charm, although the microphone quality isn't great, and the wire/cord is very cheaply made. However, after a month, or two, of somewhat heavy usage... the headset dies. Generally, it's the microphone that dies, and the headphones continue to work - for a short while, at least.
Summary: the headphones are good to use for communicating but seeing that it is a gaming pc headset and you will be having it on for a while, I found that the headset was too uncomfortable as my ears would hurt after a couple of hours of wearing it and isnt that comfortable to wear, and for the price of it, im sure you can get better ones that are more comfortable so you can have it on for a long period of time.
Summary: Now this are a decent set of headphones. The first noticable feature before you try on the headphone is the very generous 3m cable. This means you can easily walk over to the other side of the room without pulling the jack out of your computer. As soon as you put them on they just keep giving. The adjustable headset can be set and actually stay in place unlike most headphones and the microphone flexes to your comfort.
Pros: perfect sound leveling for music, great noise cancelling, long cable
