New Year, New Start. The newly released upgraded Wu HeyDay IEM from Tangzu Audio is a collaboration with trustworthy HBB (HawaiiBadBoy from “Bad Guy Good Audio Reviews”).

With HBB’s years of experience and large IEM frequency measurement database, Tangzu develops this new model that makes changes on bass and highs based on the sound signature of previous Wu Zetian earphone. HBB’s tuning and optimization has brought great changes to the new one and we wish you enjoy the new start!

The Aluminum CNC faceplate is engraved with traditional Chinese auspicious cloud pattern that manages to be both flashy and classy.

The Aesthetics of Wu HeyDay IEM

As a brand deeply influenced by Chinese history, TANGZU’s newly launched earphone Wu HeyDay still pays homage to the one and only Chinese female emperor. It is precision crafted with meticulous attention to every detail. To present the greatness of the dynasty, the new earphone adopts metal gray as the main colorway to represent the noble origins.

Upgraded 14.5mm Planar Driver

To upgrade the competitiveness in the planar battlefield, this time TANGZU is bringing Wu HeyDay to the next level with upgraded planar driver that features OCC joint wire for the speaker.

The 14.5mm planar driver with optimized bass and high frequency, this new earphone is a new attempt of the brand to pursuing an overall musical but more neutral and balanced sound with more thick and spacious signature. Theoretically, this set of planar driver IEM has improved in many technicalities and resolution.

5-Axis CNC Aluminum Case

One of the biggest improvement of the new model is the full Aluminum case, processed with 5-axis high precision CNC machine. Each material used for making this earphone is carefully selected and undergoes a rigorous testing process in order to ensure that the quality meets our expectations. The smooth shells easily fit into most average-sized ears and sit securely and tightly. As a result, it still remain comfortable over long listening sessions.

Upgraded 3-in-1 Detachable 4 Core Silver-plated Braided Cable

Despite other improvements, the bundled accessories has been fully elevated to provide HiFi-level performance. A 3-in-1 detachable silver-plated cable is included to accommodate wide range of devices while also ensure balanced sound performance. Either you want to experience next level sound quality with your private cable or simply like to change it, the Wu HeyDay provides convenience should your needs change later on

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.
