Review on 🎧 Sennheiser HD 350BT White Wireless Headphone: Bluetooth 5.0 with 30-Hour Battery, USB-C Fast Charging, Virtual Assistant & Foldable Design by Alvin Yongwei ᠌

Six months later they stopped charging. They work on USB with constant power, but the battery has stopped taking a charge. It turned out to swing the battery, now it is charging, but strangely, when the power is connected, charging does not start right away, after an hour the diode starts and lights up. Pros: Great sound, no artifacts or distortion. Working hours. USB 3.0, can be charged with a wire from a smartphone. Active noise cancellation is stated - I didn’t bother much, but they isolate external sounds well. They hold a charge for a very long time. You can use several days for 3 hours and the charge will remain 60%. I charged them once a month. Its cons: Battery problems. subject to interference. No 3.5 jack for reserve.
