Pilot USA PA-2170TH Passive Helicopter Headset.
This passive, non-clamping, lightweight, superior noise attenuating headset will exceed your lofty expectations. This model has the same comfort features as our top of the line ANR headsets such as sheepskin head pad and silicone gel ear seals. This headset comes with a soft padded headset case.
The headset is cell/satellite phone capable, and has a “true stereo” input jack so that the user can listen to music from a CD player, IPOD®, MP3® or external radio. The cell phone system is designed to work with either newer “Smartphones” that use a 3.5mm (4 conductor) input or older phones that use a 2.5mm input.
