The product is very good. The three stars are for the fact that it does not have an option for complete deactivation of Active Noise Cancelling, unlike the previous model 35ii. This is very important as in Aware mode you can hear through the headphones' microphone, which can be a bit annoying. The worst part is that many sounds are not translated well through the headphones' microphone, resulting in hearing them VERY loudly (sounds like clapping, small metallic sounds, etc., generally sharp sounds). On the other hand, the noise cancelling itself is very good. If you find the QC35ii somewhere, definitely get them instead of the QC45!!

Very good, if they had a mute button on the microphone it would be perfect. The ANC isolates you from any noise you may have around you, the battery really lasts the 24 hours as they say, they don't tire no matter how many hours you wear them

After much thought between Bose QC45 and Sony XMH, I decided on these as they are more comfortable but also in the same category as the Sony ones. Additionally, they are 60 euros cheaper and the only thing that Sony surpasses them in is noise isolation. It is good, but it could be much better. Nevertheless, it is worth it as a full high-end headphone.

I had the oldest model and due to its age, I proceeded to buy these, they do what they promise but they have connectivity issues. They often get blocked and need a hard reset. They're not bad, but look at other options as well.

The noise cancelling works perfectly. The sound is satisfactory but not exceptional. They are comfortable but I don't think they will be as much in the summer due to the leather on the ear cushions. Don't rely too much on them for phone calls, the person you're talking to hears you as if you're speaking from very far away. They have a nice design and feel. Overall, they are very good headphones but for the price I paid (260), I admit I expected something better.
