"After a few hours of charging these headphones were ready to go. I really liked the sound quality and the noise canceling option. The headphones speak to you loudly when they're connected and turned on, and also let you know when they turn off. There is also an option to use them in wired mode. I haven't explored this option yet as they hold a charge well. They are exceptionally comfortable to wear and secure. The letters L and R are printed on each inside. I can also use them to play games through Steam, the low latency ability is amazing when playing PUBG. I recommend it to everyone.โ
