TFZ started out in 2015 with a debut line up that consists of TFZ Series 1,3 and 5. Since then, they have come up with more products in the Tequila 1 and Queen. Recently, they have come up with their latest product in the TFZ Secret Garden HD. I would like to thank TFZ and Penon Audio for this review unit. You can purchase the Secret Garden HD from Penon . The TFZ Secret Garden HD that I will be reviewing is purple in colour. For more information, you can visit TFZ .
