While both provide world-class noise cancelling, high-quality audio performance, and a comfortable fit, there are a few key differences. QuietComfort 45 headphones have 2 modes of noise cancellation — Quiet Mode and Aware Mode. Bose Headphones 700 offer more customization, with 11 levels of noise cancelling. Bose Headphones 700 also offer the convenience of capacitive touch controls and hands-free access to Amazon Alexa, Google Assistant, and your phone’s native voice assistant, like Siri. For battery life, you’ll enjoy up to 22 hours* with QuietComfort 45 headphones and up to 20 hours with Bose Headphones 700
Proprietary TriPort acoustic headphone structure utilizes external ports to vent the earcups and effectively enlarge the acoustic volume, without increasing the size of the earcup. The result is better audio and active noise reduction from a smaller, lighter, more comfortable headphone.
Bose QuietComfort 45 headphones utilize both active and passive noise reduction technologies. They use a sophisticated proprietary electronics approach for active noise reduction, placing microphones both inside and outside the earcups. The electronics system senses the sound in almost any environment and then measures, compares, and reacts — instant by instant — to produce an opposing cancellation signal. Meanwhile, passive noise reduction is achieved by the combination of earcup fit, design, and clamping force of the headband.
Yes. Bose QuietComfort 45 headphones have an adaptive microphone system that allows you to use the headphones during calls when connected to any smartphone. In addition to traditional calls, the headphones will work with many apps that use Voice over Internet Protocol (VoIP), such as Zoom or FaceTime. The microphone system adapts to your environment to isolate your voice from competing background noises and wind so that you can confidently take a call or speak to your voice assistant anywhere you go — knowing you will be heard clearly and naturally.
First, make sure your headphones are turned on with the slider switch in the middle “On” position. Next, slide and hold the switch to the Bluetooth icon until the Bluetooth LED flashes blue or when the voice prompt indicates the headphones have entered into pairing mode. Please note, if this is your first time connecting the headphones, they will automatically turn on into pairing mode. Voice prompts will provide you with additional guidance. We recommend using the Bose Music app to complete the pairing process, however, Bluetooth settings on your device can be used to complete pairing.
Yes, you can continue to listen to your source even if the battery power is depleted. Without power, the headphones operate in a passive mode and neither active noise cancellation nor Active EQ is able to function.
The larger middle button on the right earcup is the Multi-function button. It initiates play/pause and other track controls for videos and music, answers and ends calls, and also provides access to your phone’s default virtual assistant, like Siri. The buttons on either side of the Multi-function button are volume +/- buttons. They allow you to easily adjust volume in an intuitive up/down vertical orientation.
On the left earcup there is a single Action button. This toggles between Quiet Mode (noise cancelling) and Aware Mode.
