The M5 is such a compact item yet so powerful. The sound is comparable to my bose machine! I originally was introduced to this device by my aunt in Vietnam. She told me she brought it while on vaca in Hong Kong. I am so glad I found this product on amazon for the same price! I highly recommend this product to everyone.
Output:
I highly recommended this speaker
