The best headset on the market for a beginning student pilot is the
Raven XE from www.pilotessentials.com

See: http://www.pilotessentials.com/produ...iation_Headset

$79 and it's the same thing as a Lightspeed QFR Solo, it's just OEM'ed
for PilotEssentials.

It's got a two year warranty and will last every bit of that and
longer. I've got two sets of these for my passengers and they are
quiet, ruggedly made, and are surprisingly comfortable and light
weight for an inexpensive headset.
