Bose ProFlight Series 2 Aviation Headset
How many dierent versions and
configurations are available for
the Bose ProFlight Series 2?
Customers can configure their ProFlight Series 2 Aviation Headsets in many
ways. Customers have their choice of connector configurations with each
module. Each connector configuration is available with Bluetooth®, and
non-Bluetooth variants in dual-plug and 5 pin configurations. Designed for
use in both civilian and military aircraft, the ProFlight Series 2 oers most
common plug configurations:
Dual G/A plug (PJ 068 and 1/4-inch stereo) – With this option, the headset is
connected to the aircraft’s intercom via a dual plug and is not powered by the
aircraft. Two AA alkaline batteries provide a minimum of 45 hours of operation
while flying. This configuration is the most common version purchased by pilots.
XLR 5 pin – Often called the Airbus plug, this configuration is a mono
connection to the aircraft and, depending on the installation, may be powered
by the aircraft. When disconnected, the flexible power feature lets the headset
switch seamlessly from aircraft power to battery power so users experience
no interruption when the headset is plugged into or unplugged from a source
of power.
XLR 7 pin – The latest ARINC defined standard pin connection, which
provides for binaural audio, aircraft power as well as separate grounded audio,
microphone and EMI/EMF shields. Although not in wide use yet, it is being
adopted by the airline industry as a new standard plug type.
6 pin connector wired to the aircraft (LEMO) – With this option, the headset
is connected to the aircraft via a 6 pin connector and is powered directly from
the aircraft. When disconnected, the flexible power feature switches the headset
seamlessly from aircraft power to battery power so users experience no
interruption when the headset is plugged into or unplugged from the aircraft.*
*Adapters are available from Bose to convert a 6 pin connector to either a dual
G/A plug or a U174 for additional connection flexibility.

Can I comfortably wear glasses with
the Bose ProFlight Series 2?
Yes. The side pads rest slightly behind and above the ear, which allows you to
put on and remove eyeglasses without touching the headset. You can wear
almost any frames you want without sacrificing noise reduction or comfort.
Can I switch the microphone to
either side?
Yes. The integrated boom mic and cable assembly can be attached to either
the left or right side of the headset. The self-guiding connector makes it easy
to attach the boom mic and cable assembly. The cable swaps easily in
seconds and without tools.
How does the ProFlight Series 2 work in
open cockpits or in aerobatic aircraft?
We do not suggest using the headset in open cockpits or outside of the
protective area behind a windscreen (typical in open cockpits). Exposure to
the slipstream will negatively impact performance. The low clamping force
and lightweight structure may not be stable enough for vigorous aerobatics.
We recommend that users use the headset on a 30-day trial to make sure it
works properly in their aircraft.
Does the ProFlight Series 2 have an
equalizer (EQ) or a way to equalize the
headset audio?
The ProFlight Series 2 has multiple built-in equalization circuits. The primary
ICS/radio communications path is designed to meet the latest TSO standard.
An additional active EQ optimizes the experience through the secondary
(Bluetooth) audio path. (Not available in non-Bluetooth option.)
