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.

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.

Great value for the money

Excellent tuning of 2 DD by HBB Collaboration. One ☝️ of my favorite EIM.

Quality at low cost

The TANGZU x HBB Wu Heyday Edition is one of the best IEMs for its price range. This planar IEM is well tuned. The sound is resolving and suitable for all day listening.

Little gem

Very good tuning especially for my library. The packaging is great and the iems definitely are worth the price.


I really love these iems. I had a problem with my local delivery service as it lost my order but I contacted Linsoul who helped a lot and sent out a new replacement which arrived in about 10 days in the UK.
Top quality customer service and fantastic products.
Thank you Linsoul.

A beauty simply.

I am a very big aesthetic guy and these iems look stunning - especially the cable. But don’t even get me started with the sound - it’s simply bringing my library to life. Great purchase, would do it again a million times :).

The one's I keep picking up!

I've been listening to the Wu Heyday for over a month and they sound better and better and better. I'm really enjoying them. I have more expensive iem's but I keep picking up the Wu Heydays. They sound wonderful and feel premium. (All-aluminum for $200, impressive). Classic rock like Steven Wilson's Yes remixes, male-female vocals like Andrew Bird or Katie Pruitt, acoustic-folk, r&b and blues all sound great. I tried several tips and for me wider opening tips like TRI Clarion or Spiral Dots work the best. They allow the Wu's tuning to shine through. Well done Tangzu!

Absolute good collaboration!

I have original zetian wu and updated heyday edition, it's a very good improvement in sound quality and accessories, now it's my favorite planar, 100% recommend.

Great for enjoying your music

This is a great one if you want an IEM with great technicalities, but also don't want the dry analytical sound. Musical, fun "wet" sound. Also the tonality and timbre is really good especially for a planar. Although, some music does sound a tad shouty and screechy... This probably depends on your Library.

I personally couldn't stand the timeless, even though it eeks out a bit more detail due to the weird tonality and timbre.

Only major downside of these IEMs maybe the size of the IEMs themselves. They are HUGE. So keep that in mind if you got small ears.
