Review on Bluetooth Wireless Earphones Dynamic Technology Headphones by Robert Hayes

★★★★★ by Micah February 3, 2020 You won't be disappointed Amazing sound and great price. Finally there is a cheap TWS with excellent sound. If you don't know KZ, they made the legendary KZ ZST Chifi headphones. The sound is pretty flat. Only slightly V-shaped. The highs are really good. The low frequencies have less bass than the S1, but I prefer less bass. I put on some foam tips and the bass was noticeably more pronounced and punchy with no loss of detail. I listened to different music for about 5 hours without getting tired. A note. There is a sheet of plastic covering the earbuds' pins. You must remove this film to charge the headphones.
