TFZ King In-ear Earphone Review


Introduction –

TFZ have built up quite a reputation with their affordable yet capable earphones, the 5S being a notable model that was instantly met with wide acclaim. Their new King seeks to compound on the successes of TFZ’s previous models, occupying the very popular $100 price tier. And when compared to competitors, the King brings one of the most innovative driver and housing designs augmented by terrific tuning that capitalises on the earphone’s technical abilities. Keep reading to see how the King stacks up to the competition and whether its aggressive, hyper-clear tones will suit your preferences.



Disclaimer –

I would like to thank Chi Kong Hui from Penonaudio very much for getting in contact and providing me with the King for the purpose of an honest review. All words are my own and despite receiving the earphone free of cost, I will attempt to be as objective as possible in my evaluation.



Accessories –

DSC02251-18I’m quite a fan of the King’s lighter coloured unboxing which is both refreshing and distinctive. Within the embossed metallic box lies the earphones and soft pouch within a plastic inlet.

DSC02259-22Underneath are the instruction and warranty papers along with the various ear tips and a shirt clip. The TFZ King comes pre-equipped with Dual flange tips though I found a better fit with the regular silicone tips. Unfortunately, no foam tips are included though the earphones are fully-sealed, providing great isolation regardless.

DSC02274-31.jpgThe soft pouch is nice and supple with a slight amount of padding that will suffice for daily storage and protection. It isn’t as nice as a hard case or the pelican style cases that are becoming increasingly common though it does the job and is ever more pocketable. The King’s are also pretty hardy on their own so I never felt that the earphones were at risk of damage.

    Hi Ryan, thanks for the review! I would like to know how they compare to the Fiio ex1 gen2, as I feel the ex1 gen2 also leans bright. Would this be similar? I’m trying to find an alternative or an upgrade to the ex1 gen2 which I quite like!

      Hi Sofia, the King has a notable advantage with fit, seal and isolation which are all very good, the EX1 2nd Gen doesn’t isolate much at all. The King is much more balanced, the EX1 2nd Gen has a considerably more recessed midrange. Perhaps the V-shaped K3 Pro will be a better fit if you’re coming from the Fiio.

    Hi Ryan
    Just want to know how this will compare to the 1more triple driver since they are in the same price range

    Hi Ryan,
    Great review for another fantastic chinese iem. I’ve purchased en700 bass after reading your review and they should be here soon. I see that you have given the highest rating to Kings, but I think they would be too bright for me. I’ll also let you know my feedback when I get my hands on en700 bass.
    Btw, which iems you will review now? LZ A4 by any chance?

    • Ryan Soo on

      Great to hear Shaan,

      Really, the quality difference between all of these earphones is not humungous so buying one that fits your preferences is the best decision. I haven’t had a chance to listen to the A4 in depth, unfortunately. Also, hope you enjoy the Simgot’s!

    Might have to check these out. I switch between HiFiMan RE-400a’s and Etymotic Research HF5’s. Thanks!
