For the first time I try noise cancelling, I am extremely impressed! It's something you have to experience to believe. It can completely eliminate external sounds depending on what's happening.

And when I say depending on what's happening, I mean that noise cancelling only works with continuous sounds like machines, air, etc. If you have children at home or something similar, it won't make much of a difference compared to regular headphones.

But when we're talking about continuous sounds? I have a busy street next to me and when I put on the headphones, it's as if it disappears. It's like being transported to a quiet and peaceful place.

Just keep in mind that I wouldn't recommend noise cancelling without playing anything. The human brain isn't accustomed to 100% silence and it gives you the impression that your ears are blocked or something. That's why some people have issues with headaches and dizziness.

In this case, at least put the noise cancelling on low so you can still hear something from the outside or make sure something is playing continuously through the headphones.

I bought them mainly for long hours of teleworking from home as well as for listening to music in my free time. For teleworking, I found them excellent. They connect automatically and quickly to 2 devices simultaneously (Laptop / Mobile) and the continuous switching is reliable and without problems. The sound/mic/Noise Cancelation is very good. The BOSE App is very helpful for full control of the headphones and I prefer it over voice assistance. In my free time, they connect immediately either to the Smart TV or to the Tablet and the sound quality for music is excellent. Finally, they are lightweight, comfortable, and the case is very good. The buttons are in the right place. I haven't tried them on an airplane yet, but indoors, for example, they reduce the noise from the kitchen hood to a minimum, so you can communicate clearly.

As for the disadvantages, I find the charging cable length to be very short, the lack of USB-C usage, and the absence of additional accessories (external mic, spare parts, battery, etc.). Fortunately, at least in the aftermarket, there are very cheap ear pads from China. As for the Bluetooth range, it is average. It is okay within the same room, but on the upper floor or in the adjacent room, communication interruptions begin.

They are worth their money, they are top-notch!

Very good sound with nice bass, excellent noise isolation. Quality construction and comfortable to use. The management of connected devices is excellent. You can switch devices with one click. It connects seamlessly with Android and Windows. As for the negatives, I would mention the price, maybe the weight, and the fact that they are not suitable for exercise, only for walking/sitting. Also, I would say that Alexa/Assistant are gimmicks. Thank you to the friend below who wrote a review on Soukou, a well-known chain that was selling them for 199€. I don't know if it was a mistake, but the notification from Skroutz saved me 50+ euros.

P.S.: After using them for a while at work, I can say that they are THE perfect headphones for this purpose. The battery lasts the whole week with plenty of talk time, the on/off button works perfectly - it connects immediately, the noise cancellation enhances the work experience during noisy office hours. As for the downsides, I will mention that the microphone picks up a lot of ambient sounds (e.g. nearby colleagues), but I manage it with mute/unmute when needed. If they break, I will buy them again.
P.S.2: After 2 years of daily use, the ear cushions have worn out. Now I have to find replacements from a Chinese seller, Skroutz doesn't have them.

I have had these headphones for a week and I can say that I am extremely satisfied. Tremendous, crystal-clear sound without overpowering bass that hides everything else. The build quality is among the best plastics, making them lightweight. To be honest, I expected them to be bulkier, but they are just the right size to carry them anywhere without weighing down your head after hours of use. The connectivity is flawless, whether from a mobile phone or computer. As soon as you open them, they connect instantly and you are also informed about the battery life, which is "endless". They fully charge in about 2 hours, and the ANC they have is fantastic, providing an incredible isolation from various noises in indoor, office, and outdoor environments.

Edit: After a year of daily use. Very durable headphones, fast charging, and a battery that lasts quite a long time. The only downside I have found is that the ear pads wear out relatively quickly, depending on usage, of course. For me, wearing them on my head for at least 5-6 hours a day, the wear on the pads was quite significant. With 5 euros from China, there are replacement pads available in various colors that can be directly attached, replacing the worn-out ones. The original ones cost around 25-30 euros.

UPDATE after 5.5 years, almost daily use!!!
The battery still holds up like in the beginning, no issues with the plastic parts of the headphones.
I only continue to change the pads every 6-8 months, which can be found very cheaply on Aliexpress, and they fit perfectly.

I bought these specific headphones 3 years after purchasing the corresponding Plantronics Backbeat ones in 2016. The reason I bought them, despite being almost double the price, was for the noise cancellation. It is indeed better than the Plantronics, however, I was expecting the incredible noise cancellation that I read about everywhere and, to my great disappointment, it was not there. In the office, I could hear conversations around me, doors opening and closing, and even keyboards. Of course, they do a great job at blocking out monotonous noises like air-conditioning, but the Plantronics did that too. Also, even when I play music (at a very low volume, of course, otherwise I would have bought music-oriented headphones), the sounds from the environment are not eliminated. Therefore, the main reason for purchasing them was not satisfied.

As for the headphone controls, they fall far behind my previous ones. Considering that they are newer than the Plantronics, this does not reflect well on them.

Also, in terms of music, the headphones are not an audiophile set. The music sounds fine, but quite flat and not comparable to other headphones oriented towards music. Of course, the music I listen to is mainly jazz and some classical, so they might be much more satisfying for other genres. However, in this case, they are not.

On other aspects of the product, an excellent case is provided, sturdy enough but also as small as needed. The battery is satisfactory and its actual duration follows the manufacturer's specifications. But this is a detail that does not concern me.

In conclusion:
- The ANC is better than others, but not as good as advertised (for office work in an open space).
- The controls are simple, but could be better.
- Musically, one can listen comfortably, but the music is somewhat "flat".
They are good headphones, but not for the price they cost. For half the price, they would get a 5/5 rating, but considering their price and compared to other competitive products, they are a 3/5 from me.

I have to say that I did not buy these headphones myself, I just have several hours of listening experience. And to help some people in their choice, I decided to write what I believe.

Build quality, although they are made of plastic, they are definitely the best plastic compared to all the others, Sennheiser, Bayer, FOCAL, etc., but they are not close to the build quality of B&W and B&O, which have by far the best construction, but they are much heavier... so you will have to decide between good quality or lightweight plastic.

The ear cushions are very, very good, they have a memory foam inside which is also the best I have seen, although they are a bit tight, so maybe some people with protruding ears might have a small issue. The battery is more than enough. Now, the sound is exactly what I want, it is warm, very warm, nothing like Sennheiser or Bayerdynamic (which I also love), the bass hits only when it goes very deep, when it is med or high bass it is very low so as not to overpower the mids. To put it simply, these have deep bass, but not fast bass, they have an audio experience as if you have a subwoofer somewhere far away. In the mids and highs spectrum, they are neither like Sennheiser, which have prominent mids, nor like Bayerdynamic, which have prominent highs. It sounds strange, but it is a completely flat sound, something I did not expect from Bose. For my taste, it is perfect, if maybe the mids were a bit higher, we would be talking about the top. I have also listened to the Sony 3 version and I have the B&W PX, the Bose are better.

I cannot have an opinion on noise cancelling. Also, the Bluetooth, wow, it is FAS-TER, incredibly fast in connection, with a huge range.
