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.
