Review on Wireless Headphones / Power Bank Case / TWS Headset with Mic / F9-5 TWS by Wiktor Janeczek ᠌

Has pros: The charge is maintained for an appreciable amount of time, not just in the earpiece, but also in the case itself. Some cons: They have a poor connection with each other, making it impossible to listen to one another. One and only. Three out of five is the rating for the sound quality. It is impossible to extend the basses using an equalization because they start to wheeze when they are stretched.
