I heard that the TFZ X1 is just mifo o5 rebranded. Is the sound distorted when comes to highs? How's the calls too? Could you list all the pros n cons?
Pro:
Relatively cheap for the performance IMO, especially when compared to the branded ones
Very light and form fitting for me due to its small size
Battery life is above average, I've yet to drain it in a single session.
Sufficient button operating functions, play pause skip ahead and back songs, and open up AI. Should be able to answer calls but I haven't tried it.
Mine was from Taobao but can switch between English and Chinese language
I answered a call by holding 1 side as a mic and close to my mouth, seems to work well enough.
The build quality of both earpieces and case are of quite high quality.
Most importantly, the signal connection is one of the best I've tried, I do sometimes have dropped signals but they're infrequent and seldom last beyond 1 second.
Con:
I would have preferred the earpieces shell to be made out of metal but maybe that would have interfere with the signal strength.
The biggest con I can think of have to do with the sound quality and the use of a single BA driver. This means there is a limit to how well it can perform. It doesn't reach as high or low as a single DD or multi BA driver, but at least the sound is acceptable to me, I'm able to tolerate it for the pros listed above.
