Tangzu & HBB Team Up For Wu Heyday Edition

Another set of IEMs is getting the HBB treatment. Brands like Yanyin and Tripowin have gotten upgrades to some of their top-tier products, like Tripowin’s Olina. These upgrades come from Hawaiian Bad Boy from “Bad Guy Good Audio Reviews,” who has had years of experience accumulating a large frequency measurement database. The latest set of IEMs to have the “HBB” name attached to them is the Wu Zetian from Tangzu. With this new model, Tangzu aims to make a few adjustments to the Wu’s sound signature, particularly its bass and treble.

Unlike other HBB collaborations, the Wu Heyday doesn’t change much to its shell design from the Wu Zetian. It still pays homage to the Wu’s Chinese history aesthetic, but it is given a new metal grey aluminum faceplate processed with 5-axis high precision CNC machine. The 14.5 planar drivers is going to be the main focus of this upgrade, now featuring an OCC joint wire for the speaker. this new earphone is a new attempt of the brand to pursue an overall musical but more neutral and balanced sound with a more thick and spacious signature.

This collaboration also includes an upgraded cable. An all-new 3-in-1 detachable 4-core silver-plated braided cable is included to accommodate a wide range of devices while also ensuring balanced sound performance. You’ll get 3.5mm/2.5mm/and 4.4mm adapters with this new cable.
