Review on Beoplay H9 3rd Gen Wireless Bluetooth Over-Ear Headphones by Bang & Olufsen - Active Noise Cancellation, Transparency Mode, Voice Assistant Button and Mic, Matte Black (Amazon Exclusive Edition) by Ae Ra ᠌

1. Noise reduction has only one mode. Not bad, but if you need noise reduction, it’s better to take bose 35 IMHO 2. Only support 1 device 3. Hands-free microphone could work better 4. No hard carry case However, IMHO these are trifles. But the ears are more about "a beautiful, convenient thing for listening to music on business trips, taxis, home office, not very noisy office, sometimes to talk." If you need something non-marking, designed for a noisy office, public transport, what you can take on a picnic, etc., then it’s better to take something like bose 35
