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

Value For Money

Ergonomic design and great fit for my ears. Useful and quality accessories. Detail retrieval is excellent, with a relatively wide soundstage and great separation of instruments. Bass goes relatively deep while treble is present without sounding fatiguing over time. Recommended.

Colin Tan
Its good

For the price bracket it competes with other planar magnetic IEMs at the same or even higher price points, with good accessories and is just overall a joy to listen to

Best planars so far

I've heard a few of the new planar IEM models Not many But out of the ones that I have heard I believe the Heydays are the best of the bunch. Yery musical


I don’t own a lot of IEMs but this is by far my favourite. Smooth natural sound quality that I can listen to for hours without fatigue. Hats off to. HBB for his excellent tuning and guidance.

The CREAM of Planar IEMs

This IEM gives a serious competition to some of the widely spoken IEMs (beyond the price range bracket)...

Its about the sub bass.. the balanced/relaxed tuning...

Excellent job by HBB..

The Tangzu for audiophiles

These IEMs have a balanced tuning that makes it useful for monitoring work. In addition, the detail retrieval and relatively wide sound stage make it easy to separate different instruments in the music. Build quality, accessories (especially the cable), and presentation are exquisite at this price range, and if you are looking for a planar that is well-tuned (balanced), without that emphasis in the treble region (“planar sheen”), this is a really good choice.

Hey to the day.

Well balanced. Similar to stock but better build and cable. Timbre is natural and I dont get the metallicy sound other planars can convey. Recommended in this price category.
