Introduction
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 .

Thanks for the review! Do you think the increase in sound quality after Queen is enough to buy Secret Garden

Thank you! I would say yes as the Secret Garden is more engaging than the Queen.

Thanks for the review(s)! I’m was about to get these as you suggested a few days ago, and then the Tanchjim Oxygens popped out on Massdrop (3 days left to join the drop). They cost about the same so I just wanted to hear your opinion which one you think is better overall (and bass & soundstage compared)? Thanks! I am really looking forward to your review of the O2!

Hi, the SG HD has a stronger bass performance while the Oxygen is more incisive. The soundstage of the Oxygen is bigger. I think the Oxygen is better overall.

Thanks for comparing the two! I think I’ll have to go with the O2. Or wait for the possible O2 II because of the fit issues.
