I bought kaira pro for playstation headphones 4 times and all 4 times I came across defective/ defective ones. I first picked up used on Avito (Russian marketplace) for 8000 rubles, they are barely enough for 3 hours without the vibration and backlight, second time took in the CSN (one of Russia's largest electronics stores, which sells only original products as they claim, and in fact it is, but they are incidents when still under the guise of the original comes marriage) hyperspeed version (as usual only with the ps logo) for 17500, they have battery everything was in order only when the battery level is below 40% they yelled in my ear low battery every few minutes for 3 hours (this is with dynamic lighting and the average vibration), for the third time 3 weeks ago, took over 12000 usual also in the CSN they have a defective battery, but it is one day put it on the charger all night kept charge 8 hours, and another 2 hours have been screaming low battery, try to charge poverbank, power pack xiaomi 5 watts and ps5, and also yelling in my ear low battery when the battery level is less than 40%, only to have every 5-30 minutes Took 4 times 5 days ago last version at the same price and they have a battery of the same, only yelling low battery when charge is under 20%, and the last 2 charge indicator in the application Razer Audio is not displayed correctly, unlike hyperspeed version, she always correctly display the battery level. In the application, all headphones were displayed as kaira pro, only the hyperspeed version was displayed as kaira pro hyperspeed, I checked the latest headphones on the website by the serial number on the box and they were determined, inside the box there was a thank-you letter with a signed promo code card and documentation, I don't think I have a fake, I also noticed that Bluetooth alerts about low The charge is not coming, what could be the problem?
Ps: i used kaira pro with ps5 and phone through dongle
