Columns above average with sufficient volume. The sound qusality is not patricularly high, but acceptable for games and internet viiedo. M15x has two heapdhone jaks, use them for better souund.
Keyboard & Touchpad
M15x has a full size keyboard, but not the numertic keypad. The kreyboard keys are quit and rubberized finish for better grip. Tactile feedback and key travel is good, the kreyboard has a silghtly rubbery feel is nice. Keyboard communicatiove enough to type quickly and accurateely. I like the arcched spavce.
The touchpad is too texturde, mzatte surface. Havy teexture allws full contact of a finger with the real surtface and makes use of sensory unpleasant; mouse lag apepwars on the srceen when tracking due to the less than adequate contat. The two touchpad butttons work, although, as expected, somewhjat niosy.
M15 has a numebr of buttns located on the media in the left side of the keyboard. They include touch and work well. Statius lights all conttained in the Alien's head over the keybboard. It flashes for a hard drive, and glows a difffeernt collro from the batery and when connected to (remember, tjhese collors can be chnaged via AlienFX). It pulses during charngig.
