The Dolby 5.1 mix provides decent usage of the left and right channels with a few atmospherics (an unforgivable appearance of a freakin» howitzer early and late - film announces itself in the rear and the sub-woofer) to spice up the largely dialogue and folk tune - driven track.
There's a decent 20hz — 20kHz frequency range, support for AAC and aptX LL, and 4 hours of usage per charge with the carrying case providing another 12 hours of charge.
