Bose ProFlight II, Aviation Headset

FAQ

• What improvements do the ProFlight Series 2 headphones have over their predecessor?

  Based on user feedback, we've implemented several optimizations. The cable is now thinner and lighter, providing greater mobility and reducing the weight on the head by 11 grams. The touch control for out-of-intercom communications has been refined. Additionally, the microphone arm now features fins for proper adjustment and alignment. We've updated the carrying bag with a carabiner and a loop, as well as a more spacious internal design.

• Between the ProFlight Series 2 and the A30, what distinguishes them? Are they suitable for any aircraft?

  Although both headphones have common features like Bluetooth and the stereo/mono audio option, they are fundamentally different in design. The A30 has a closed structure, ideal for noisier, unpressurized single-engine aircraft. In contrast, the ProFlight Series 2, with its internal headband design, is better suited for pressurized and quieter aircraft, like most jets.

• Is it comfortable to wear glasses with the ProFlight Series 2 headphones?

  Definitely yes. The ear cushions sit just behind and above the ear, allowing glasses to be put on or taken off without interfering with the headphones. This gives you the freedom to wear almost any type of glasses without sacrificing comfort or noise reduction.

• Can the microphone be switched from one side to the other?

  Absolutely. Both the microphone arm and the integrated cable can be placed on either the right or left side of the headphone. Thanks to the self-adjusting connector, the connection is always secure.

• How long do the ProFlight Series 2 batteries last?

  Using two AA batteries, these headphones offer at least 45 hours of use under typical aircraft noise conditions. If Bluetooth is used continuously, this time is reduced to a minimum of 25 hours. As always, duration can vary depending on battery type, environment, and active features. They also have a light indicator to inform when it's time to change the batteries.

• Can I use rechargeable batteries with these headphones?

  Although technically possible, it is not advised. Rechargeable batteries progressively decrease flight time from the initial 45 hours. Furthermore, they might affect the accuracy of the battery life indicator, which could result in less time than expected.

• Is it feasible to use lithium-ion batteries?

  Using lithium-ion batteries is discouraged due to their voltage, which is typically higher than recommended.

• What is the automatic power-on feature?

  Models that can be powered from the aircraft (6 and 5 pin XLR connections) will automatically turn on when they detect power from the aircraft. A switch on the module allows this feature to be adjusted according to personal preferences.

• How does the auto-off feature work?

  The ProFlight Series 2 have a feature that detects inactivity. If not used for a period ranging between 6 and 45 minutes, they will automatically turn off to conserve battery.

• What does the TSO standard mean and why is it relevant?

  The TSO (Technical Standard Order) sets the minimum performance requirements for equipment, components, and materials in civil aviation. Having a TSO authorization ensures that the product meets these standards. Bose Corporation not only complies but in many cases exceeds these requirements. However, having a TSO authorization does not guarantee approval for use on a specific aircraft.

• In terms of noise reduction, how do the ProFlight Series 2 compare to the A30?

  The ProFlight Series 2, while effective, do not offer the same level of noise reduction as the A30.
