Bose QuietComfort 45 vs. QuietComfort 35 II – What are the main differences?

Wireless headphones have become an essential device in everyday life. Not only do they allow you to enjoy music with great comfort and in practically any situation and place, but over the years they have incorporated technologies that have significantly increased sound quality and usage time.

This last sentence can summarize the line followed by the North American company Bose, seeing itself reflected in two of its wireless headphones: the Bose Quietcomfort 35 II and the Bose Quietcomfort 45.

In the first place we find the Bose Quietcomfort 35 II, a versatile model that continues to meet the demands of users up to four years after its release on the market. It may be precisely for this last point that the American brand has decided to launch the Bose Quietcomfort 45 on the market, a new model that is more an update of the previous one than a novelty in itself, but that must be analyzed to discover its full potential..

In summary, Bose bets on the safe side by improving key sections, but without making the mistake of changing what already works.

The question is… is it worth renewing the headphones?

Bose QuietComfort 45 vs. Bose QuietComfort 35 II – Comparison Table

Here you will find in detail the specifications of both models face to face. A technical analysis that will make you make the best decision.

Identical to the naked eye

The mantra of this comparison could be the numerous points on which both models coincide. In fact, in the visual aspect they find hardly any differences.

As we can see in the comparative table, both the dimensions and the weight are very similar in one and the other.

However, there is a variation in the USB input that the headphones present. The Quiecomfort 35 II comes with a Micro USB input, while the Quietcomfort 45 brings the novelty of a USB-C input.

As for the layout of the buttons, there are no relevant changes.

In short, if we are looking for a word to summarize the appearance of both models, we can use the term “continuity” without a doubt.

Autonomy

Wireless headphones are synonymous with freedom, movement and music that accompany you at all times, but to unite these three factors, a very important characteristic must be taken into account: autonomy.

And that is something that the North American brand has taken great care of. The Bose Quietcomfort 35 II offers up to 20 hours of continuous operation. On the other hand, in the Quietcomfort 45 the autonomy is extended up to 24 hours, that is, a full day of non-stop music!

This is directly related to the charging time. Both one model and the other have an autonomy that borders on the exceptional, but how long does it take to have the headphones fully charged? The answer is 2 hours on the Quietcomfort 45 model and about 2.5 hours on the Bose Quietcomfort 35 II.

In addition , both headphones can have an autonomy of up to 3 hours with just fifteen minutes of charging, so there is the possibility of performing a quick charge to continue listening to your favorite songs.

Sound

But if we talk about wireless headphones, the fundamental aspect to take into account is the sound quality that each one offers.

First of all, it must be said that both the Quietcomfort 35 II and the Quietcomfort 45 have a noise cancellation system, although the latest model goes one step further in terms of quality, since the Quietcomfort 45 has more capacity to achieve almost perfect isolation.

Yes, we must highlight the Conscious mode, only present in the Bose Quietcomfort 45. This system allows you to detect any outside noise that could lead to a dangerous situation. Think of a car horn or a bicycle bell. Thanks to the Conscious mode you can enjoy the music and, at the same time, be aware of what is happening around you.

The Bose Quietcomfort 35 II, on the other hand, does not have Aware mode.

The winner?

The passage of time has treated the Bose Quietcomfort 35 II very well, since the simple fact of comparing it with a current model reflects the potential and quality of the headphones. Four years is a world in this sector, but that does not seem to be a problem for this model.

After this reflection we have to say that several factors must be taken into account in order to make the right choice.

First of all, if you are looking for wireless headphones, the choice of the Bose Quietcomfort 35 II is very interesting since you can find it at a better price than the Quietcomfort 45. We have seen that the differences with its predecessor are few, so you are not giving up a superior experience.

In case you own a Quietcomfort 35 II and are thinking of renewing it for the new model, you have seen that its specifications do not go much further, so it may be worth waiting for a new release from Bose.

However, if you are looking for the latest wireless headphones on the market and saving is not your priority, the Bose Quietcomfort 45 is undoubtedly yours.
