"It has been almost two years since we first heard of LTB Audio
Systems and decided to look at their USB True 5.1 Surround Sound
Headphones. The headphones were surprisingly well designed for coming
from this relatively unheard of company. Listen To Believe (LTB) has
recently introduced their Magnum 5.1 USB Headphones, which is what we
will be looking at today. These headphones offer a built in microphone,
onboard audio control, and is true 5.1 surround sound."
