I can tighten them very securely to side rails because the shape of the mounting bracket matches the shape of the side rails very well. It has an elevated bass, linear mids, and slightly elevated treble with harshness. I dont know with the price of over a $100 if its a great choice for the begginer gamer. First off, the sound quality is very clear. - Good bass. If this does break. Width is very narrow. Pretty disappointed with this unit. when you gain expierance with gaming on a keyboard get a 60 percent Pitfall of online shopping.
