Top critical review
May 26, 2019
I am first surprised by the fast delivery (without prime, it arrives in two days).
Its ANC reduces background noise (like the noise made by the fan in the computer, the AC) effectively, while people's voices, irregular sounds are still there, which is not ANC designed for (I just did not know it before).
The instruction is helpful and I easily got the headset paired to my laptop via bluetooth and play music from it.
The connection lasted until I walked through two rooms to a restroom, and once I stepped back, the connection was reestablished automatically.
Haven't tried those advanced functions like skipping a song or picking up a phone call yet.
The music quality sounds good to me.
=== update ===
It is comfortable enough to hear for a while, but if you plan to wear a headset all day, you really need to find a more comfortable one.
The battery capacity could have been reported at a finer grain (not by 20%).
I had trouble to get the bluetooth work with my old laptop, neither the advance control functions.
The customer service did not reply promptly but eventually gave me reasonable answers. Just be patient to them and they will be patient to you as well.
