I had used them about 15 times and then I had left them for a while. When I charged them again, the headphones do not charge from the case. The case is charged

I have had many wireless headphones in my hands and I have to say that in the case of the Cetra, it depends on whether you come from better or worse quality headphones. Reservedly, I will say that yes, they are good (sound, microphone), they stick to the ear and don't come off easily, the marketing they did makes them look good because they almost deliver what they promised and they do it quite well. I won't say that I am thrilled for the €110, they could have been cheaper for what they offer.

One negative aspect is their connection with the Armoury Crate... it's a hassle.

Anyway, it's a purchase that I don't regret, if you are a fan of Asus, go for it. (but definitely not for more than €110)

Very good sound, the armoury crate application gives you the ability to change the sound experience in depth with pre settings or manual setting! Very good response in gaming mode without any delay in sound even in demanding FPS video games! I highly recommend it. Also, it is beautiful. Asus warranty

I got them for use at work, with plenty of meetings throughout the day, and the over-ear ones were quite tiring. They connect very well to the PC compared to other headphones of the same type. Clear sound in speech. Good noise cancellation and good battery.

Quite good headphones, the price is expensive but it's what we call you get what you pay for, I recommend them

Good sound and easy pairing with PC and mobile personally. Not very comfortable for gaming, ears hurt after a while.

Also, if for example you eat slowly, they come out of the ear and you have to put them back in
