Bose QuietComfort 45: noise cancellation and more autonomy to listen, but also to speak a lot and well

The range of high-end headphones from this manufacturer is renewed with the new Bose QuietComfort 45, which take the baton from the popular QuietComfort 35 II and do so with major improvements.

These include its improved noise cancellation system, a new “Aware” mode to be able to hear outside sounds while we use them and, above all, its autonomy, which is 24 hours on a single charge.

Speech isolation in conversation

A design that lasts because the differences are on the outside

The QuietComfort 45 design is practically identical to its predecessors although there are some minor differences. They can be found in black and white, and there are four buttons on the right earbud for volume control, pairing, and power.

On the left earpiece we find a button to change between the two operating modes, Quiet (with noise cancellation working in full) and Aware, a mode that allows us to hear outside noises even using headphones.

In addition to that noise cancellation we can also enjoy the voice isolation if we use headphones in conversations: the QuietComfort system is capable of picking up the sound of our voice and discarding other external sounds, something that according to those responsible for Bose is especially useful in videoconferences.

One of the sensible improvements of these new headphones it is in its autonomy, which arrives at 24 hours. Charging is done via USB-C: it is possible to fully recharge them in two and a half hours, and with just 15 minutes we can enjoy three hours of audio playback.
