Bose QuietComfort 45 headphones - Refurbished

5 out of 5 Customer Rating
What's a Refurbished Product?
A refurbished product is one that’s been returned to Bose, for any reason. It’s then thoroughly inspected, tested, and serviced to meet strict Bose sound quality standards — the same as a new product. Appearance is closely examined; products occasionally have minor, nearly imperceptible blemishes. All refurbished products have the same warranty as new products and are available only from Bose. Quantities are limited.
There’s comfort in quiet. You can feel it the minute you put them on. The soft, plush cushions seal you in. You press the button and whoosh — the world fades, the music starts, and it’s love at first listen. That’s the power of our QuietComfort 45 Headphones with signature active noise cancelling technology and premium comfort. Bose QuietComfort 45 Headphones also deliver proprietary acoustic technology for deep, clear audio with adjustable EQ so you can tune your music to your liking. They're wireless headphones with a perfect balance of quiet, comfort, and sound that you’ll enjoy all day long.

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.

Aware Mode turns on the external microphones of QuietComfort 45 headphones and feeds ambient sounds into the headphones, enabling awareness of the sounds in the environment, such as cars and emergency vehicles, while still enjoying audio content.

These headphones were designed to maximize all the features that contribute to comfort, especially when you’re using the headphones for extended periods of time. All materials have been selected for their comfort and lightweight properties. Protein leather is used for its comfort, durability, and acoustical properties. The earcups rotate easily for a uniform, comfortable seal. And most importantly, stability is achieved with minimal clamping force, allowing for hours of comfortable wear.

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. Multi-point technology allows Bose QuietComfort 45 headphones to maintain a connection to two devices at the same time — for example, an iPad and a smartphone. So while you’re watching video on the connected iPad, the headphones will automatically pause the video to answer a call from the connected smartphone. When the call is finished, the headphones switch back to the video on the iPad.

Bose QuietComfort 45 headphones have a range of up to 9 metres (30 feet) from the source device. This range may be reduced by physical obstructions, such as walls and doors, or by interference from other electronic devices. Pops or a cracking noise may be heard if there’s interference with the Bluetooth connection. If that happens, move away from wireless routers or microwaves and bring your headphones closer to the Bluetooth device.

The headphones can be charged using the USB-C cable supplied in the box and plugging into a USB port on a PC, laptop, or wall charger. Allow up to 2 hours for the headphones to fully charge. The battery light indicator will show an amber light while the headphones are charging and turn green when fully charged. When you don’t have time for a full charge, the fast-charge feature provides up to 3 hours of play time from a quick 15-minute charge.

Bose QuietComfort 45 headphones use a lithium-ion rechargeable battery that provides up to 22 hours* of audio playback with noise cancelling turned on.

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.

Yes. Bose QuietComfort 45 headphones come with a USB-C cable that allows the headphones to be charged from your PC or laptop. Please note that the PC or laptop must be on and awake in order to charge over USB.

Bose QuietComfort 45 headphones also give you two options when it comes to audio EQ. Do nothing, and the bass, midrange, and treble of whatever you’re listening to will be adjusted automatically to make it sound great. Or choose Equalizer in the settings of the Bose Music app to change the audio levels yourself to however you like them best. Either way, you’ll enjoy immersive sound at any volume.

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.

Using the Multi-function button on the back of the right earcup, QuietComfort 45 headphones give you access to your phone’s default virtual assistant, like Siri.

No. In general, the audio/video delay will be excessive and most noticeable in games where action and audio are supposed to be synchronized.
