Ergonomic Shape, Comfortable Fit

Fit is something to audiophiles. TANGZU has specifically designed the products to provide the perfect fit, outstanding comfort and a pleasant listening experience simultaneously. It’s build based on large data of human ears via a precise calculation on the shell measurement to ensure to meet the sweet spot of fitting for the majorities. We believe the unique design will satisfy different tastes and preferences


TANGZU, a brand inspired by the most prosperous traditional Chinese dynasty-Tang Dynasty, a golden age of Chinese arts and culture, has been keeping its roots by releasing three iconic models successively: Li Yuan, Li Shimin, Wu Zetian and the brand-new Wu HeyDay. TANGZU is a brand of broad vision and exquisite craft.

Empress Wu Zetian was the only female emperor of Imperial China. She reigned during the Tang Dynasty (618-907 CE) and was one of the most effective and controversial monarchs in China's history. By naming the new earphone this way, TANGZU intentionally brings unprecedented sound performance to the community with the 14.5mm planar driver and finely tuned three frequencies. We believe that Wu Zetian will surprisingly outperform its competitors.

Absolutely amazing

Best IEM's for the money. Great detail and resolution. Best tuned planar IEM you can get. Fantastic.

Detailed with just the right hint of bass

These are the best experience after horrible isine 20 without cipher cable.
No eq is needed, these are fairly neutral with all the layering and details available on tap.
Eq it to get more bass, YMMV.
I'm a happy camper with the stock tuning. Great buy at the price!

Pros: Cable, the stock tuning

Cons: Included ear tips. Tips selection is just a formality, I'm using Xelastec and find them good.

Very good at its price point

My next best set is at half of the price (Moondrop Aria), but I’ve listened to some high end speakers and headphones before and on over the ears the Sennheiser HD58x is my daily driver.
The Zetian Wu Heyday is really solid and I heavily prefer them over the Arias and thus they became my daily driver.
I’m listening to a wide genre mix off the Apple Dongle and a desktop DAC / Schiit Vali combination, which includes some classic rock, movie scores, HipHop and a lot of female Vocals.
It plays all of this in a good, fun way without any obvious bad parts. The tuning here is very good to my preference.

The higher power from the Desktop setup had no significant impact, although the sound changes a bit because of the tube.
The bass comes in good quantity without being overwhelming, some sample Tracks include The Batman Dark Knight OST and Kill Jill which HBB also often references. It is a bit elevated, but not highly. The original Wu and the 7Hz timeless have more bass looking at their graphs, but this set feels very good on bassy tracks.
Mids play relatively smooth and precise.
The treble is well extended although the snares and hi hats are sometimes a bit weird, but that can be related to the music production.

Build quality and the cable are truly very good with metal casing and a nice braided cable with interchangeable connectors.
Unfortunately I cannot compare it to the other recent planarian or the blessing 2 Dusk. However I’m certain that this set is very good and continues the trend of recent chi-fi products to redefine what’s possible in the price brackets.

Very-very good

I have been truly impressed by the sound since it was an impulse purchase for me and I did not expect much to be honest taking into account the price. Very good kit as well.

I just received my pair and I am love with them! They sound amazing and the packaging feels premium. I enjoy the tuning in these however the original ones have better bass. So if you are into more bass the original ones are better suited for you. I love the extra mouse pad that was included as a thank you for being one of the early buyers. I am so happy with my purchase! I recommend these whole heartily.

Simply amazing for the price!

Perfect tonality to my ears and great technicalities especially for the price!
