Providing Measurements

Rarely do a company provide measurements but TFZ have frequency response graphs on their website. What they use to make them I have no idea, nor can I read the Chinese on the site but I can understand the graph at least. I screen grabbed it for you guys to have a look.

Of course I used my Vibro Veritas to make some measurements.


While they do show similar curves, especially to 2kHz, after that the Veritas as noted before shows less information of a similar trend. This shows a bass boost of just under 10dB as well as a boost towards 2kHz and again before 5kHz.

    So, do you like the TFZS1? Is it worthy next to the many IEMs out there?

    • The bottom line, yes I do for the price. It is not performing way above its price but if you haven’t got a lot to spend and want some bass, this is worth a shot!
