I just got them from a chain of stores (I wanted to have the 2-year warranty for sure and be able to easily communicate in case of a problem). They have very good sound and you can make additional adjustments from the creative app. They hear me quite well on calls. I haven't worn them long enough to know if they are tiring or not, but I will return. I wanted a pair for use at the gym, so it will be seen if they don't fall off and if they are comfortable, and if they hear me well in speech (Check). It also has active noise cancellation which is very useful.

Having the headphones for almost a month but I change my rating to mediocre for the following reasons:
The bass is indeed quite intense and overshadows the other frequencies, becoming quite tiring after a while.
The sound is dull, it lacks "color", it's just a "dry" right left... compared to the Edifier w820NB which lack in build quality but excel in sound analysis.
The sound with the cable is slightly lower compared to the bluetooth function.
Sometimes when the ANC is on, the left speaker sometimes reproduces an annoying sound.
Overall, I was not very satisfied for the 80€ I paid for them...
The app is ok, it has an equalizer that somewhat saves the situation, but still lacks "color".
There is no case or even a pouch included... a detail but worth mentioning.
On the positive side, very good build quality with reinforced metal headband, rotating cups, and foldable design.
Supports wired and wireless operation.
Has a very good low latency mode (I don't notice any delay in sound and image playback in videos).
They can be connected simultaneously to two devices... although I couldn't manage to do it...
Has three modes:
Ambient mode (you hear the ambient sound, quite convenient if you are on the go, you hear the cars, etc.)
Active noise canceling (reduces sound very well, but sometimes if we move our head, especially to the left, an annoying sound is heard, not always)
Normal mode (fits well being over-ear, has sound isolation plus minimal external noise is heard)
It has both wired and wireless operation.
Very good especially if you run out of battery, they can be used with a cable (the Edifier W820NB do not support a 3mm jack cable).
Includes a Type C cable and a 3mm jack.
I have the cream color and they do not get dirty (the white Edifier w820nb, which we also have, get dirty very easily).
They are comfortable and lightweight, and because they fold, they are easy to carry.
The leather ear cushions are comfortable with good isolation and cover the entire ear (I don't see them being removable to be replaced in case of wear).
On warm days, it is logical and expected for the areas where the headphones touch to sweat.
The microphone is very good and sounds very clear in calls.
The battery lasts for several hours and charges very quickly.
They do not get dirty easily.
If the price was up to 50€, I would recommend them... but at 80€ there are alternatives and with a little more we go to another category...
