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.

  1. Have formed a desire to get these but am very worried about that housing size. But I have no real way of knowing just how big it is. What I do know is that I once bought these IEMs called Revonext QT3 and found them impossible to wear the to size ( and maybe shape too). Would anyone here possibly be able to tell me how the TFZ King housing size compares to those ?

  2. Hi Hugo, depends what you’re looking for. In terms of detail and resolution, I would think so, but if you want more bass, the others will likely suit you better.

  3. Hi Ryan,
    Thank you for reviewing this fantastic item. Can you compare TFZ King and RHA MA750 which one is better. Thanks

  4. Hi again Ryan,

    Thank you very much for the reply. The reason i mentioned Yamaha was because of the 2016 guide of recommended earphones where Yamaha was the next step from Pistons. However this review persuaded me to look at my other options in the same price range as well. Now that i know that i should rather go with TFZ 5, it basically comes to price and availability for me. Thanks again.

  5. Hi Amin,

    Unfortunately, I haven’t heard the Yamaha’s so I can’t provide direct comparison or recommendation. I would perhaps point you towards the TFZ Exclusive 5, it is similar to the King with a nice soundstage and resolution but it is also more v-shaped with a warmer low-end that will be better suited towards films. I think it will be a more natural progression from the bassier Piston earphones and you get the added benefit of a removable cable over the Yamaha while retaining a nice metal build.


  6. Hi Ryan,

    Great work reviewing this product. Just a simple question; i am planning to upgrade from my Piston 2. I was planning to go for the Yamaha EPH-100 but with this being in the same price range i have a decision to make. I mostly use the news set to play games and watch movies and listen to music occasionally. Which one do you think suits me best considering i really like my Piston set.

  7. Hi Ryan,
    Great,detailed review. Can you please compare the Fiio f5 and Tfz king based on sound quality alone.
    F5 is cheaper and both have removable cables. Does the sound quality justify the kings higher cost? Also in your opinion which is the best iem under 100 usd for sound?

  8. Noted, thankyou so much for your reply!

    Looks like I’m gonna have to plan a long trip to the big city to demo all of these side-by-side, instead of just order from home. So many choices!

  9. Hi Darryl,

    Based on your sound preferences it doesn’t sound like the King will be a perfect match; it has a bright midrange with female vocal emphasis and treble is moderately forward and aggressive. It is relatively balanced but not nearly as neutral as the RE-400, the King has substantially more bass and treble than that model. Unfortunately, I haven’t heard the GR07 mkII in quite a while so I can’t provide comparison.

  10. Hi Ryan,

    I would like to know how these compare to the popular VSonic GR07 mkII and HiFiMan RE-400. I’m looking for something balanced along those lines but brands like VSonic are hard to find here now.

    I like a little treble sparkle but am very sensitive to harshness and sibilance. I love good mid-mids but not too much high-mids. Thanks beforehand for your advice.

  11. 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.

  12. 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!

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

  14. 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!


  15. 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?

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