This pilot headset is the panel mount version of the H10-13XL. It has a permanent panel-mount setup that allows it to operate off of your aircraft's power source in addition to the battery power module. The ENC technology reduces noise by up to 22 dB and the M-7A electret microphone transmits crisp, clean speech without the burden of background noise. The 5 foot coil cord has a quick release mechanism.The double foam headpad on this H10-13XP pilot headset reduces pressure on your head as does the gel ear seals, so you can wear it for long periods of time and still be comfortable. If you want, you can switch it over to stereo mode and use the unit with an entertainment system in your cabin.
