These headphones are great for the price in terms of durability, comfort, and sound. Sound Quality When reviewing sound quality, it is important to have some kind of comparison. Otherwise, rating it by number could be vague (i.e. what I consider a 4, you may consider a 10). With that said, the sound quality is very good. Compared to Sony's MDR-V6 and Souls 150 by Ludacris, there's more bass. Equalizers can always be used for tweaking the X10 to your preference, but these are great for gaming, movies, and other various entertainment uses. Studio production use is also possible though I believe that then comes down to a higher level of personal preference. The moment you put on these headphones, you'll notice the noise cancelling immediately. Comfort The ear pads are kind of squishy and soft. I could wear these the whole day and would not have to deal with the pressure on my ears that most other headphones apply. At the same time, it isn't so loose that they feel like they'll fall off very easily. Design The design (fashionably speaking) is great for in-home entertainment or for a DJ at a club. I would not wear these on the streets only for safety reasons, primarily the noise cancelling reduces your ability to be aware of your surroundings more. Functionally speaking, the auxiliary cable that attaches to the headphones have a locking mechanism (just insert and turn clockwise), which is great if you have problems with the cable pulling loose. On the other hand, it may mean that your headphones will fly off as well. It really depends on what you're doing with it and what situation you're in.
