Review on Wireless headphones Sony WH-1000XM4, silver by Adam Woniak ᠌

Got pros: I have wanted these headphones for a long time and finally bought them. The sound quality is great, and I really like that I no longer have to play music loudly due to external noise. With its cons: The charge for 30 hours does NOT hold exactly. Maybe 10 hours max. I can not understand whether this is really normal, or a problem with the battery
