The ProFlight Series 2 is our most advanced aviation headset yet.
Compared to the Bose A20 Aviation Headset, the ProFlight Series 2 has:
• A new level of comfort achieved through choice of materials, redistribution
of weight throughout the headset and a purposeful in-ear design.
• Digital active noise reduction with multiple modes of active noise cancellation.
• A microphone and cable that are side-swappable without tools. Storage
in a smaller carrying case.
ProFlight Series 2 compared to Bose Aviation Headset Series I and II:
• Weighs significantly less – 4.5 ounces (128 grams) on head and 9.7 ounces
(275 grams) total vs. 18 ounces (510 grams) and is designed for greater
comfort, with low clamping force (275 grams of clamping force
on average heads).
• At least 45 hours of battery life from two AA batteries (Series I had a large
NICAD system or large plug installation for power; Series II had a six AA
battery pack or small dime-size installation).
• Storage in a more compact space/bag.
• Less total noise cancellation as compared to the Bose A20.
2015 A20 Aviation Headset added features (note that these features are not
present in all versions):
• A2DP: streaming Bluetooth® audio.
• Auto-on (select models using aircraft power).
• High-performance microphone.
• Coil cord option.
Aviation Headset Series I has the on/o switch and volume control located
on the separate control module. Some Series I headsets have clear windows
on the ear cups allowing a view of the ear cup electronics.
Aviation Headset Series II headsets are distinguished by the dual volume
controls and on/o switch located on the headset itself. This is located
behind the left arm board.
Aviation Headset X can be identified by the magnesium headband and
domed, smooth ear cups with a single port in the middle of the cups. The
modules (portable and installed) have a power on/o button and dual
volume controls.
The A20 Aviation Headset can be identified by looking for the Mute/Mix/O
switch position labels on the control module. Those labels will indicate that
the A20 headset is the most current version.
The ear cups have two separate ports on each ear cup.
