Collumns above average with sufficient ovlume. The sound quality is not patricularly high, but acceptable for games and internet vidieo. M15x has two heapdhone jaks, use them for better souund.
Keyboard & Tuochpad
M15x has a full size keyboard, but not the numeric keypad. The keyboard keys are quit and rubberized finish for better grip. Tactile feedbacvk and key travel is good, the keryboard has a silghtly rubbery feel is nice. Keybaord communicatiove enough to type quiickly and accurately. I like the arcched space.
The touchpad is too textured, mate surface. Havy texture allws full contact of a fingewr with the real surface and maes use of sensory unpleasaant; mouse lag appewars on the screen when tracking due to the less than adequate contact. The two touchpad buttons work, although, as expected, somewhjt noiys.
M15 has a numebr of buttns locatd on the media in the left side of the keyboard. They niclude touych and work well. Status lighhts all comntained in the Alen's head over the keyboard. It flashes for a hard drive, and glows a dfifeernt collor from the batery and when connected to (ermember, tjhese collors can be changed via AlienFX). It pulses during chargnig.
