Bose ProFlight Series 2 ANR Aviation Headset LEMO 6 Pin Aircraft Power with Bluetooth 789812-5040

What is the difference between the Bose ProFlight Series 2 and the Bose A20 or A30?

The ProFlight Series 2 uses a lightweight in-ear design built for the moderate noise of pressurized jets and turbine flight decks. The A20 and A30 are around-ear headsets aimed at louder piston aircraft and helicopters. Choose the ProFlight Series 2 if you fly professional jet or corporate aircraft and value its 4.5 ounce comfort.

What connector does this version use and how do I confirm it fits my aircraft?

This is the 6 pin LEMO version, model 789812-5040, which plugs into panel mounted LEMO power jacks common in many jets and corporate aircraft. Bose also offers dual plug and 5 pin XLR configurations. Confirm which jack your aircraft has before ordering this LEMO model.

Does the 6 pin LEMO version need batteries to operate?

This is the 6 pin LEMO Flex Power configuration, supplied new. Flex Power lets it run on aircraft power through the LEMO jack while also accepting two AA batteries as backup. It carries a five year limited warranty, and orders over one hundred dollars ship free within the United States.

How much does the Bose ProFlight Series 2 weigh and why does that matter?

It weighs only about 4.5 ounces, making it one of the lightest aviation headsets available. The low weight and in-ear design help reduce fatigue and discomfort during long flights and extended duty periods, which is why it is built for professional jet, corporate, and commercial pilots who fly many hours.

How long does the battery last and how does Bluetooth affect it?

Bose rates the ProFlight Series 2 at about 45 hours on two AA batteries. Running Bluetooth audio continuously shortens that runtime, so carry fresh spares for longer trips. Since this is the LEMO Flex Power version, it can also draw aircraft power, with the AA batteries serving as a dependable backup.

Which batteries should I use in the ProFlight Series 2?

The headset uses two standard AA batteries and is rated around 45 hours of operation. An automatic shutoff feature helps preserve power when the headset is left unused, so you are less likely to drain the cells between flights. Keeping fresh spare AA batteries on hand is a smart habit for longer flights.

How many noise reduction modes does it have and when should I use a lower setting?

The ProFlight Series 2 offers three selectable active noise reduction modes, so you can tailor it to your cockpit. Higher settings give the most quiet for loud phases of flight, while a lower setting makes face to face conversation easier without removing the headset, helping you balance quiet with situational awareness.

Is the ProFlight Series 2 FAA certified, and what does TSO mean?

Yes. This Bose ProFlight Series 2 is FAA certified and carries TSO authorization. A TSO is a minimum performance standard for equipment used on civil aircraft, so the authorization signals the headset meets a recognized benchmark. Paired with the electret noise canceling microphone, it supports clear, reliable communication in professional flight decks.

Can I connect my tablet, phone, or EFB to this headset?

Yes. This version includes full Bluetooth connectivity with audio prioritization, so audio from your phone, tablet, or electronic flight bag mixes smoothly with your aircraft intercom and radio. There is also an auxiliary audio input, and the improved tap control lets you talk to others without removing the headset.

Can I wear the Bose ProFlight Series 2 with eyeglasses or sunglasses?

Yes. Because the ProFlight Series 2 uses an in-ear design rather than large over-ear cups, glasses and sunglasses temples do not break a seal against your head. This is one reason many professional pilots prefer it for long duty days, since it stays comfortable while you wear eyewear in the cockpit.

Can the microphone be moved to the left or right side?

Yes. The Bose ProFlight Series 2 microphone can be attached on either the left or the right side to match your seat position and cockpit layout. This flexibility helps first officers, captains, and instructors set the boom where it works best for clear transmissions through the electret noise canceling microphone.
