I am enjoying it since many weeks and found no problem at all. It is very to connect with mono or stereo mode. The most interesting feature is that both earbuds can be used for two different devices at the same time. Earbuds are very light weight and comfortable to wear for long time without causing any irritation to ears.
It has Bluetooth 5.0 compatibility that means strong enough to remain paired with device without any distortion. I charge its charging case at night and it never finished even I used earbuds throughout the day to charge them again and again. I have continuously used earbud for three hours, but their battery was not exhausted. I also like its charging case because it has a compact deign with a closing lid that protects earbuds perfectly. I am happy for this excellent purchase.
