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. Six-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.You can wear almost any frames you want without sacrificing noise reduction or comfort. The self-guiding connector makes it easy to attach the boom mic and cable assembly. The cable can be swapped easily in seconds and without tools. With continuous operation of the Bluetooth function, battery life will be at least 25 hours. As always, battery life varies with the type of battery, the noise environment and features used. The headset’s battery life indicator light alerts the user when batteries should be replaced. Rechargeable batteries also alter the accuracy of the battery status indicator light, so that when the light changes to amber, you will have less than the usual eight hours of flying time remaining that you can expect with non-rechargeable AA alkaline batteries. A switch inside the control module battery compartment can be used to configure this feature based on user preference. The exact time it takes to power off varies and can range between 6 and 45 minutes of inactivity. When a company is authorised to manufacture a material, part or appliance to a TSO standard, this is referred to as TSO authorisation. When a company receives a TSO authorisation, it is assured that the product meets these minimums in both design and production. Bose Corporation meets all, and exceeds many, TSO requirements. Receiving a TSO authorisation is not an approval to install and use the authorised article in the aircraft. It is designed to meet the unique needs of pilots and crew who fly pressurised and crewed aircraft, which are typically less noisy. 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—128 grams (4.5 ounces) on head and 275 grams (9.7 ounces) total vs. 510 grams (18 ounces) 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 five-pence-piece-sized installation). 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. Coiled cable option. One of the best parts of using a Bose Headset is the Bluetooth capability. With Bluetooth, you connect a device by pairing it wirelessly with a source; you do not need a cord to make the connection. Pairing connects other Bluetooth devices with your Bose headset, but first, you must turn on pairing mode. Here is how. Manually Turning on Pairing in Your Bose Headset To pair your Bose headset with a Bluetooth-enabled device: Turn the headset upside down so that you are looking at the bottom of the headset. Move the power switch to the On position to turn on the headset. Move the headset close to the Bluetooth-enabled device that you want to pair it with so it can be discovered. The second device must also be powered on. Press and hold the call button (or another button specified in the instructions for your specific device) on your headset for about five seconds to put the headset into discoverable mode. You will see a slow-blinking indicator light. From the second device's Bluetooth device list, choose the option for the name of the Bose device you are pairing. If the device name does not up, go back to the Bose device and repeat the steps to get it to show up. After you select the device, you may be prompted to enter a password or to confirm to accept the connection. If you are asked for a password, Bose says to type in 0000 and then press OK. When the pairing has completed the connection, the Bluetooth indicator light flashes again and turns a solid color. Ten seconds after the pairing is complete, the light turns off. Turning on Pairing Mode With Bose Connect App In addition to manually pairing your Bose headset with a Bluetooth-enabled device, you can use the Bose Connect app to turn on pairing mode. The Bose app manages the Bluetooth settings for multiple Bose devices. To pair your Bose headset with the Connect App: If you have not already, download the Bose Connect app from the iOS App Store or Google Play. Open the app and go to the Connections section. If this is your first time connecting, click the Connect New option. On your headset, make sure the power light is on and that you held down the Call button to turn on pairing mode. Your device should now show up on the Bose Connect app. Select it by its name. Once the device is connected, the indicator light blinks for two seconds, and the app reports that it is Connected to (Name of the Device). If you need to disconnect your device, you can do so from the app, and if you choose to reconnect it later, locate your device's name in the app under the Connections subcategory History. There, devices that were previously connected are available to reconnect. When Bose Headset Does Not Pair in Connect If your wireless headset does not show up in the Bose Connect app, confirm that the headset is on and try again. If that does not work, reboot the device. You can also try closing and reopening the Connect app, and if you are on Android, enable location services or clear the app's cache to reset the app's settings and, hopefully, fix the problem. Bose QuietComfort 35 Not Pairing Certain headsets, such as the QuietComfort 35 wireless headphones, sometimes have issues struggling to connect. If you find your Bose QuietComfort 35 not pairing, clear the Bluetooth list on both your headset and the Bluetooth devices you are trying to connect with. To clear this pairing list, slide the power switch of the headset to the Bluetooth symbol and hold it for 10 seconds. You should hear Bluetooth Device List Cleared. Then, do the same on the Bluetooth connected device and delete the QuietComfort 35 name from the device's Bluetooth list. That should solve any issues of Bose QuietComfort 35 not pairing. Bose SoundLink Speaker Not Pairing While it is not a headset, you might find that your Bose SoundLink speakers have trouble pairing too. If this happens, reset Bose SoundLink and the Bose SoundLink app. To do so: Hold the Mute button down on your SoundLink speakers for 10 seconds until the LED lights flash. Press the Power button to turn the SoundLink back on. Clear the pairing list on both the Bose SoundLink speakers and the Bluetooth device you were trying to connect to. To reset the Bose SoundLink pairing lists, hold down the Bluetooth button for 10 seconds. A tone sounds when it is done, indicating you cleared all Bluetooth devices from the speaker's memory. Try to pair the device again. To make your speakers discoverable, hold down the Bluetooth button for three seconds. This light blinks on and off about once per second, which is how you know that pairing mode is on. Now, connect to the speakers from your Bluetooth-enabled device, and your device should be paired.

James B. 5.0 out of 5 stars My wife hates them. My wife hates them she would give it 1. I put them on and that’s it. I can’t hear her any more.I would agree, they both sound excellent. The Bose won the test for its noise cancellation, performance talking to people on the phone, comfort on my head, and sound processing. Phone performance: I compared how the Bose and the Sony sounded when recording and playing back my voice with a fan running in the background. The Bose sounded like I was holding an old fashioned handset and talking in a quiet room - intimate and zero background noise. The Sony sounded like I was on speaker phone, and I could hear some background noise. (As a control I also recorded using neither and it sounded like I was on speaker but also I could hear more background noise.) This feature is important to me since I spend a lot of time on the phone and prefer my clients to not hear any background noise. Sound quality The Bose and Sony both have excellent sound quality for playing music. I personally prefer the sound the Sony produces. The Sony iphone app lets you choose your levels on an equalizer, and I like that. However, the Bose hears what type of music you're playing and automatically optimizes the sound, and it does a really good job. While I would prefer to be able to set the levels if I so choose, I also appreciate that Bose is making it all easy for me, so I can truly listen to my music on random and not have to fuss with levels. The Bose iphone app doesn't do very much at all. The Bose on the other hand just stops the noise. There is no delay, no white noise, just quiet and your music. Controls The Bose controls are intuitive to find and to use. I like that the on-off control is a switch to flip on and off (rather than a button to find). Also, you can use this button to switch between devices, for example between your phone and ipad and your TV amplifier. The right earcup has three small buttons in a row together, and they control a lot of things. The left earcup only has the google assistant button, which I programmed to instead control the amount of noise cancellation (high, low, off). Song playback sounds much better with noise cancellation on high, and I don't think that has to do with noise (I was in a quiet environment); the bass sounds enhanced with noise cancellation on for some reason. (In comparison, the Sony lets you swipe the earcup itself to control volume, pause, play, skip, etc. This seems great in theory, but in practice if I bumped the earcup adjusting my glasses or whatever, the music would pause.
