ANC Wireless Bluetooth Over-Ear Headphones with HiFi Stereo Sound

The headphones arrived a week earlier, which is very pleasing. Easily connected to the phone through the official application, updated. Everything would be fine, however, I have a question about the headphones. Previously, black headphones were bought a year ago, and the markings on the inside are different from the white ones. Also, with the white ones, the noise cancellation function when touched to the right ear turns on with a noticeable delay (2 seconds), all of this is concerning and makes one doubt the originality. p.s forgot to mention, also previously bought two black earphones as a gift and they also have markings, a QR code, and no delays. p.p.s the packaging arrived undamaged, everything is in place.
