The most popular aircraft connection option is dual G/A, but flexible power versions with auto-on capabilities are also available in 6 pin and 5 pin XLR configurations.

The most common connection configurations are:

• Dual plug (PJ 068 and . inch stereo): With the dual plug, two AA alkaline batteries provide a minimum of 45 hours of operation while flying. This version is user-configured for stereo or mono audio and is commonly used across all aircraft types.
• XLR 5 pin: This configuration, often called the Airbus plug, is a mono connection that’s powered by the aircraft or batteries, depending on the aircraft’s capabilities. When disconnected, the flexible power feature allows pilots to switch seamlessly between aircraft and battery power.
• U-174: The U-174 is a single-plug configuration commonly used in both military aircraft and several helicopter models.
• LEMO) 6 pin connector: With this option, the headset is connected to the aircraft via a 6 pin connector and is powered directly from the aircraft. Two AA alkaline batteries can also be used to enhance flexibility. When disconnected, the flexible power feature allows pilots to switch seamlessly between aircraft and battery power.*

*Bose adapters are available to convert a 6 pin connector to either a dual G/A plug or a U-174 for additional connection flexibility.

• Can I comfortably wear glasses with the Bose A30 Aviation Headset?

Yes. The earcups have supple leatherette-covered foam cushions that provide an effective acoustic seal – even over glasses. Pilots should be able to comfortably wear thin-rimmed glasses without significantly diminishing noise reduction.

• Can I switch the microphone to either side?

Yes. The integrated boom mic and cable can be attached to either side of the headset with the toolless connector mechanism in a few simple steps.

• How does the A30 Aviation Headset work in open cockpits or aerobatic aircraft?

We do not suggest using the headset in open cockpits or in environments without a windscreen. Exposure to the slipstream will negatively impact the headset’s performance. For aerobatic aircraft, the low clamping force and lightweight structure may not be stable enough for vigorous aerobatics without the use of a third-party skullcap or retention system. We recommend users try the headset with the 30-day trial to ensure it’s compatible with their aircraft.

• Does the A30 Aviation Headset have an equalizer (EQ) or a way to equalize the headset audio?

The Bose A30 Aviation Headset has multiple built-in equalization circuits. The primary ICS/radio communications path is designed to meet the latest TSO standard and to optimize voice intelligibility. An additional active EQ helps optimize the experience through the secondary (Bluetooth®) audio path for wireless audio sources.

PRODUCT TECHNOLOGY

• What is the latest technology in the Bose A30 Aviation Headset?

The Bose A30 Aviation Headset includes several important technology developments. The most significant advancement is the new digital active noise reduction system that provides full attenuation in even louder environments compared to the Bose A20, which is the current industry leader. In addition, the new system provides a renewed balance of attenuation across the entire spectrum of noise based on user selectable modes. Bose proprietary microphones both inside and outside the earcup enable optimized performance in loud environments across a range of frequencies. The small electronics system senses the sound by more effectively measuring, comparing and reacting to produce an opposing cancellation signal. The proprietary ear cushion design provides additional passive attenuation, and the headset design uses carefully selected materials to block noise from entering the ear and further improve comfort. In addition, the headset features a high-performing microphone for communication and a Bluetooth® audio communications interface, both weighing in at just a fraction of competing headsets.

• How does the noise reduction in the A30 headset compare to the A20?

The A30 has a similar amount of total noise reduction compared to the A20, but with a renewed balance and user selectable modes.

• Does the A30 have sensor capabilities similar to other headsets on the market?

At the moment, there are no sensor modules available, but the A30 has advanced architecture to support sensors via modules that can be plugged into the nonboom side of the headset.

NOISE CANCELLATION

• How much noise reduction does the Bose A30 Aviation Headset provide? What is the attenuation at different frequencies?

The Bose A30 Aviation Headset provides three modes of user selectable noise cancellation that were individually engineered for specific use cases. “Low” helps optimize interpersonal communication outside the use of an intercom system. “Medium” provides the most consistent amount of reduction across a wide range of frequencies, and “High” provides the most active noise reduction to maximize the signal-to-noise ratio for radio communication. All three modes have been engineered for distinct uses.

Bose does not make claims about the mode of noise reduction. We encourage pilots to try the product in a variety of aircraft to experience the dramatic performance and capability of each mode for themselves.

• What is the EPA-rated attenuation of the Bose A30 Aviation headset?

The current methods specified by the EPA Noise Reduction Rating (NRR) cannot be applied to active noise cancelling devices. The EPA is currently redefining the NRR, with an explicit goal of including active noise cancelling devices in its scope. In addition, the latest TSO standards identify the latest ANSI test standards relating to active noise reduction headsets, which Bose both contributes to and complies with.

• Does it have an audio output limiter like Sennheiser’s “peak level protection”?

No, there is not a limiter. All headsets provide output up to 110dB, per TSO requirements.

• Does Bose offer noise cancelling in helmets for pilots or motorcycles?

Bose does not offer active noise reduction within helmet systems. Bose is always researching ways to solve problems with innovative technology offerings.

• What is talk-through tap control?

Double tapping an earcup in high or medium ANC modes will shift that earcup into low mode, enabling voices outside of the intercom to be heard more easily. If the earcup is already in low mode, then tapping will not change the setting.

• Do I need special permission to use this headset on my airline? Are STCs required?

Airline requirements vary greatly. Some allow pilots to use headsets of their choice while others require an approved list of products.

• Can a hearing aid be worn under or inside the earcup?

Consult your audiologist. Many hearing aids create feedback when amplified sound escapes the ear and is picked up by the device’s microphone. By placing an object near the hearing aid – such as a cupped hand – the amplified sound is reflected to the microphone, making the device more likely to “whistle.” While many modern hearing aids suppress feedback with digital signal processing, a headset around the hearing aid can result in sustained feedback.

Because hearing loss varies from person to person and across different frequencies, removing the hearing aid and increasing the headset volume may not be sufficient. Consult your audiologist to determine the best configuration for audio intelligibility and the safe operation of the aircraft.

COMFORT

• What makes the A30 Aviation Headset so comfortable?

Overall, the Bose A30 Aviation Headset is one of the smallest, lowest-clamping and lightest around-ear active noise cancelling headsets on the market – it’s a balance of function and comfort without sacrificing stability.

The headset’s angled earcups follow the contours of pilots’ heads, and the intentional shape of the headband pads help achieve the highest level of comfort in the lowest possible on-head weight. Additionally, the A30 has distinct left and right earcups with a quick release and a side swappable mic for improved comfort and ergonomics.

• What attributes make Bose cushions better?

The materials of the headset cushions were chosen for their soft feel and stable fit. The headband cushion provides the exact amount of force needed to distribute weight and pressure across the head to avoid hot spots or bottoming out.

• Have the ear cushions and headband been tested for health, safety and long term use? Have there been any tests regarding skin reactions or test certificates?

Bose does extensive tests to ensure the products we create do not cause skin irritation. When possible, Bose chooses materials that yield the best results for biocompatibility.

• Can the new headset be worn when pilots suffer from auditory eczema (exostosis)?

The materials in Bose headset cushions have remained consistent for years with tens of thousands of units in operation without significant issues. In any case, customers with skin conditions should consult a doctor for advice.

• What is the weight of the headset without cables?

The total headset weight is 524 grams (18.48 ounces). The on-head weight (includes the headphone and half of the upper cable with boom mic) is 404 grams (14.25 ounces).

BLUETOOTH® AUDIO INPUT

• What is the purpose of the Bluetooth® input?

The wireless input is available so users can connect external sources such as an EFB or tablet computer, a GPS or even a cell phone.

• Is it legal to use a Bluetooth® device in the cockpit?

Yes, but pilots are personally responsible for permitting and utilizing personal electronic devices or any devices that emit radio signals. Depending on the country, circumstance and use case, different methods of qualification and approval may be required.

• How do I record audio to and from the headset?

Audio is best recorded with the help of separate devices, applications and adapters between the headset and the aircraft to optimize performance. This includes adapters that overlay the recorded audio with video.

• How do I control the volume of Bluetooth® audio?

Pilots can control the volume from the Bluetooth®-connected device or via volume controls on the side of the control module.

CUSTOMIZABLE AUDIO PRIORITIZATION

• What is customizable audio prioritization?

Priority switching allows pilots to customize their audio sources. There are two options for audio prioritization:

• Mute: When the switch is in the top position and an intercom signal is detected, all secondary audio sources are muted (streaming Bluetooth® and wired auxiliary inputs).
• Mix: When the switch is in the middle position and an intercom signal is detected, Bluetooth® audio is mixed with the intercom audio. (Phone calls are always mixed.)

• How does customizable audio prioritization work?

The control module has three user-defined prioritization states:

• Mixed audio position: The intercom signal will mix with the auxiliary audio input signals.
• Muted audio position: The auxiliary input signals will be muted when an ICS signal is present.
• Off: Auxiliary audio sources are completely turned off to ensure sterile cockpit operations.

Note: When a Bluetooth® call is present, the audio from the call will always mix with the ICS signal. The Bluetooth® function is always disabled in the passive mode and when battery life indications are red/low.

MICROPHONE

• What kind of microphone does the Bose A30 Aviation Headset have?

The A30 uses a noise cancelling electret microphone (often called a high impedance microphone), which is typical for aircraft. It is optimized to reject farfield noise and improve performance when used with “hot mic” systems. A 5 ohm and a 150 ohm dynamic microphone are available in specific configurations.

POWER AND BATTERY

• What is the battery life of the Bose A30 Aviation Headset?

The A30 operates for a minimum of 45 hours from two AA alkaline batteries in typical aircraft noise. With continuous operation of the Bluetooth® function, battery life will last 25-plus hours. As always, battery life varies with the type of battery, noise environment and features used during flight. The headset has a battery life indicator light to signal when batteries need to be replaced.

• Can I use rechargeable batteries?

Yes. However, flying-time battery life may be lower than the acclaimed 45-hour life, depending on the type of battery chemistry used. Rechargeable batteries may also alter the accuracy of the battery status indicator light; when the light changes to amber, pilots will likely have less than eight hours of flying time remaining.

• Can I use lithium-ion batteries?

Multiple battery chemistries can be used, including lithium-ion batteries. Pilots should be aware that the battery life indications may vary based on the type of batteries used.

• How are the batteries installed?

The two AA batteries fit lengthwise in the bottom of the control module. To access the battery compartment, push down and slide the cover toward the headset. After the cover has cleared the detent, lift it into a vertical position and insert the batteries.

• What is flexible power?

Flexible power is a feature available for headset configurations that allow aircraft power. This feature allows pilots to switch seamlessly from aircraft power to battery power. If needed, adapters to connect the headset to the aircraft are available for purchase from Bose or third-party manufacturers.

• How does the auto-on feature work?

Headsets that can use aircraft power (6 pin LEMO and 5 pin XLR) will automatically turn on when aircraft power is present. A configurable switch inside the control module can disable this feature based on user preference.

• How does the automatic shutoff feature work?

The automatic shutoff feature detects when the A30 is not in use and shuts off after several minutes (ranges from 6 to 45 minutes of inactivity) to preserve battery power.

• Can I use the Bose A30 Aviation Headset to listen to audio from a Bluetooth® device even when I am unplugged from the intercom?

Yes. As long as the headset is turned on, audio can be played through the Bluetooth® connection. However, Bluetooth® audio will not play when there are less than two hours of battery remaining in the headset.

The Bluetooth® capability is available when the headset is turned on and the priority switch is set to either “mix” or “mute.”

• What does the blue or purple light mean on the Bluetooth® module?

The blue and purple lights on the Bluetooth® module indicate the status of the Bluetooth® functionality. A purple flashing light indicates that Bluetooth® is on and the headset is discoverable or pairing but not yet connected to a device. A blue flashing light indicates that Bluetooth® is on and connected to a device.

• How difficult is it to install a flex-powered version into my aircraft, and how much does it cost?

The process depends on the aircraft and where the aircraft connector would be installed. The system consists of six soldered wires: two audio, two microphone, a ground wire and a power wire. Installing near the existing phone and mic jacks is a quick process because four of the six wires can be attached directly to the back of the jacks. This also allows existing jacks to still be used with conventional headsets.

• Why is the battery-powered control module the same size as the installed, aircraft-powered control module?

Installed, or aircraft-powered, versions of the Bose A30 contain a feature called flexible power circuitry. Headsets with flexible power circuitry can be powered by the aircraft or by batteries. This allows users the flexibility of battery power with an adapter cable. Because batteries take up to 70% of the control module space, the modules were designed to be the same size. The adapter cable is useful if you fly in other aircraft without an aircraft-powered connector, or if you want to disconnect from the aircraft for a quiet flight with active noise reduction.

• Do the aircraft-powered versions (6 pin LEMO and 5 pin XLR connectors) require batteries for any of the functions?

No. These versions of the Bose A30 Aviation Headset do not require batteries for any function when connected to the aircraft. However, if you have batteries in the module, you can continue to use the headset when it is disconnected from aircraft power. For example, you could make a private phone call with the Bluetooth® version of the headset by disconnecting from the panel. It also enables you to use a small adapter cable to fly in other aircraft instead of purchasing a new down cable with different connectors.

CERTIFICATIONS AND TSO

• What is TSO and why is it important?

A technical standard order (TSO) is a minimum performance standard for specified materials, parts and appliances used on civil aircraft. TSO authorization means a company is authorized to manufacture a material, part or appliances to TSO standards. When a company receives a TSO authorization, the products meet the minimums for both design and production.

Receiving a TSO authorization is not an approval to install and use the authorized article in the aircraft.

• How do I prove to a check pilot that a product is TSO-certified?

There are markings inside the control module and under the headband pad of the headset that indicate TSO certification.

• What is Bose’s position on the InFO document from the FAA on noise cancelling headsets?

Bose supports the recommendation in the InFO memo, which says operators should thoroughly evaluate headset performance in their own aircraft. Each aircraft type has unique acoustic qualities, and Bose believes real-world testing is the best way to evaluate performance.

The Bose A30 Aviation Headset meets or exceeds all FAA TSO requirements for pilot headsets and has been thoroughly tested in various aircraft. Civilian and military pilots have accumulated millions of flight hours during the 25-plus years our products have been in the field.

• How easy is it to hear other crew members in a lower-noise environment with the headset on?

Because active noise reduction technology excels at lower frequencies (below 1 khz), the Bose A30 Aviation Headset will not completely cancel voices. Essentially, this means that voices can be heard in situations where they would normally be completely drowned out by aircraft and wind noise. In addition, the low mode of operation helps optimize communication outside the use of an intercom. Talk-through tap control shifts the tapped earcup into this low mode and improves directional hearing for communication on just the ear that was tapped.
