The first thing that I noticed about these headphones was how comfortable they are, they have an auto-adjusting headband. They sound different than other headphones that I have used, and can take some getting used to if you are using them with a computer or ipod. If you can use a headphone amp they will really come to life in my opinion. I use the headphone jack on my Onkyo receiver, doing this really improves the sound I think. They are only 40 ohm so they are easy to push, being so you can use them with phones or ipods. I use mine a lot and they have held up good, I will say don't push them too hard with a headphone amp because I have messed mine up doing so, I will be buying another pair because their sound when used with the correct equipment is perfect and they are extremely comfortable. They also include a 3.5mm to 1/8 in adapter which is gold plated same as the 3.5mm connector, they also have a very long cord so their not the best for travel. But they are very durable because on more than one occasion while gaming they got slammed to the floor and didn't break.
