The design of the device is different from others, at the top we have two USB ports, and then a small LED display to show you FM frequency, 1 microphone at the left of the display, 1 Multifunction Knob/key and 2 buttons for next and previous songs play.
The left USB is for fast charging with 3.1 A and the right one is just 1A, it can be used for both charging and USB drive reading. With two USB port, you can listen to music from your flash drive while you charge from other port. But you may have plugin issue if your drive width is more because of side by side USB. On the right side, there is an option for TF card also.
You can play music with low power consumption using Bluetooth 4.0, Handsfree Call Function, Voice broadcast etc. It is compatible with all Android and iOS versions. With one mUltifuction key, you can answer/reject/recall. The Bluetooth has 5-meter range.
According to review on Amazon, the device has good quality sound, but sometimes there is some noise while in call and some connection issues.
