Model: 101Z

The main box is designed with a very large inner concave dial, which is not only the scale but also the pointer, so the blind operation is also very handy.In addition, a lotus mouth connected to the secondary box is designed behind the main box. Because it is a MINI speaker, the power of 202 is not large, so the USB power supply is more than enough, but as a portable speaker is unfortunately not a battery-powered, after all, with dry electric 2 pools to the power supply doesn't make how much volume increase.In addition, the signal-to-noise ratio of 101 is 80 dB, which theoretically guarantees high quality sound playback.
