Bose QuietComfort 45 & Ultra share many similarities, but there are also important differences, such as sound quality, performance, features, design, and connectivity. If you want the best one between them, I Would recommend the Bose QuietComfort Ultra rather than the Bose QuietComfort 45.
Why Do I Recommend The Bose QuietComfort Ultra?
- The Bose QuietComfort Ultra has Advanced ANC, advanced algorithms & better hardware to block out more ambient noise, providing a high-quality listening experience, but the Bose QuietComfort 45 has basic ANC.
- It includes touch controls for a more modern, sleek interface compared to the button controls on the Bose QuietComfort 45, which feel less intuitive.
- The QuietComfort 700 features Immersive Audio settings and Custom Tune allowing for personalized sound adjustments. The QC45 lacks built-in EQ customization.
- It supports high-resolution audio & features a more refined sound profile with enhanced bass response and clearer highs, while the QuietComfort 45 does not match the fidelity and depth.
- The Bose QuietComfort Ultra has ten microphones to enhance call clarity even in noisy environments, but the QC45 has fewer microphones.
- Upgraded Bluetooth 5.3 in the QuietComfort Ultra ensures a more stable connection, improved range, and potentially lower latency than Bluetooth 5.1 in the QuietComfort 45.
- QuietComfort Ultra provides up to 24 hours of listening time for extended travel or long listening sessions, compared to 22 hours for the QC 45.
Maybe the Bose QuietComfort 45 price can make you comfortable because it’s a little bit cheaper than the Bose QuietComfort Ultra. But you have to compromise all the above-mentioned features. Now the Decision is Yours. I hope it was helpful to choose the right one.
