Bose QC vs Bose 700: What’s The Difference?

When it comes to noise-cancelling, you can’t really go wrong with either of these models as both offer a great experience; however, the QC 45 model does outperform the 700 model with improved noise-cancellation technology. In terms of simplicity, the two noise-cancelling modes available with the QC 45 are easier to navigate and more user-friendly. Concerning sound quality, the difference is slight but noticeable with the QC 45 slightly edged out by the 700 model. Both models offer a sleek and modern design, but the battery life of the QC 45s is noticeably longer. The microphone quality of both models is good, suitable for either business or everyday calls.

Bose QC 45: A Closer Look

The QC 45 retails at around $329 (from the Bose website). Although more expensive than some of their alternatives, they come in cheaper than their predecessors. They were released in 2021 as the successor to the QC 35 II model, offering a sleeker design, longer battery life and improved noise-cancelling technology.

The battery life is around 24 hours with noise-cancelling and Bluetooth enabled. Adding to this, they fold completely inwards, meaning the QC 45 is perfect for long journeys and working away from the office. Offering USB-C support and quick-charge capabilities, these headphones are perfect for when you’re short on time.

They feature two new noise-cancelling modes – ‘quiet’ mode blocks out all surrounding noise, while ‘aware’ mode lets in some noise, i.e. the sound of traffic so you can be more cautious depending on where you are listening.

The QC 45 boasts improved sound quality over its predecessors, with vents added to the earcups. The quality is better not only for music but for calls as well, with another built-in microphone added in comparison to the QC 35 II.

If you’re after the reliability of physical buttons, you’re in luck with the QC 45. Four buttons are found on the right ear (multi-function, action and volume control buttons) and one on the left ear (for turning noise-cancellation on and off).

Bose 700: A Closer Look

The Bose 700 comes in at $379 (from the Bose website), being one of the more expensive options from Bose. However, the 700 has long been their flagship model, and for good reason – unmatched sound quality. Even though they were released in 2019, Bose’s newer models have yet to rival the 700 in this regard. With a modern design and range of four available colours, there’s a 700 for everyone.

The 700 has a battery life of 20 hours, definitely long enough for most uses, and has quick-charge functionality. Like most Bose headphones, they’re great for portability and are also capable of quick-charging via USB-C.

Noise-cancellation is excellent with the 700, and is controlled by an adjustable scale; levels from 1 to 10 mean you can change the mode to suit your individual preference and environment.

Touch controls are a feature of the 700, being used for the most common functions (playback, volume control and song selection), but buttons are still present. Power, noise-cancellation and voice-assistant are all controlled by physical buttons, but noise-cancellation can also be adjusted via the Bose Music App. Spotify Tap is also compatible with the 700, which is great for returning to your laast listening session just through a tap and hold of the right ear cup.
