The TFZ King is a Chinese IEM that many have posted positive reviews of. Now I see why; this IEM is pretty good, if it has a few flaws.

The housing is made of a fairly solid feeling plastic, and has a non-removable, but sturdy, cable. While the cable on the unit I have is non-removable, the only listing for the King I could find on Penon Audio was for a newer version with a removable cable, with what looks like a 2-pin connection. Fortunately, however, the attached cable has rather low microphonics, and I would likely not want to replace it if I had the newer version.

The King is extremely easy to power: at 16 ohms and 110db/mW, any device is capable of driving it to ear-bleeding levels. That being said, it did benefit slightly from being powered by my Magni 2 over my iPhone 6s.

It comes with few accessories: a few sizes of silicone and foam tips, a shirt clip, and some memory wire wrap that you can put on the cable.

This IEM is also rather comfortable, with the housing putting no pressure on my ear. The cable itself feels alright on my ear, and while I did try the memory wire wrap, I personally did not like it.

The sound of the King is overall a bit bright, but far from overly so. The bass on the King is very slightly elevated, and has plenty of thump, but never sounds muddled. While it is not the most detailed bass, instead feeling like a gently throbbing presence, it is very pleasing in its presentation. Bass, while plenty present in the King, does not take center stage, instead taking a backseat to the rest of the mix. The midrange itself sounds bright, with a clear elevation in the upper midrange relative to the lower midrange. Vocals on the King can sound slightly thin, but despite this, sound rather natural, remaining engaging. Instruments can sound slightly confused, with subpar imaging, but still sound natural enough to be fun. The treble sounds very good, providing plenty of sparkle. Nothing sounds hazy, and everything in the upper frequencies sound very well defined and clear. I cannot complain about the treble; it is very good. The King’s soundstage is surprisingly wide, having some of the widest soundstage out of any IEM I have used. While the soundstage is wide, the imaging is a bit lacking. It images well enough to not offend, but it could certainly be better.

Overall, the King is a good IEM. At 100USD, it is a good buy, and I can see myself recommending it. While I would not say it is worthy of rave reviews, it is certainly a solid unit well worth the price tag.
