Review on Edifier W820NB Headphones - Hybrid ANC - Hi-Res Audio - 49H Battery Life - Bluetooth Over Ear Wireless Headphones for Phone Calls - Black by Adisorn Nasa ᠌

More about noise reduction: it does not muffle all sounds, such as more expensive models or earplugs, but makes them quieter. If someone contacts you while your noise reduction is turned on, you will hear him, but you will not understand anything. Has some pros Good enough sound, comfortable fit, ears don’t sweat (but it’s not hot yet) and don’t get tired (I can sit for 4 hours without a break), the noise reduction is not strong, but muffles the surrounding sounds, charging lasts for 2-3 days with moderate use. Has cons: There is only one negative, when connected to my Mac mini with m1 and entering the game, the sound changes, namely it becomes a little lower and every 5 seconds there is a rewind for 1 second. Because of this, it is unpleasant to listen to music / a movie and play, only turning the headphones off and on helps, but the next time you enter the game, this repeats.
