For such little money, you should not expect more from them. I bought YouTube for my mother to watch - she is quite satisfied, she says they are comfortable, she is satisfied with the sound. With its pros: Paired with Apple, Huawei, Samsung Audio delay relative to video is not noticeable. Cons: The sound margin is small - quieter than conventional wired ones The sound is muffled, no better than from the tablet speakers Ears diverge tightly, on a large head they can press Huawei defined as two devices. Headphones remember up to 8 devices, however, in order to reconnect, you need to go to the previous device, disconnect there and connect to the next one. Not suitable for Zoom. With Windows, the microphone is not connected. When using, significant lags began, the image hangs, the sound disappears.
