NEW COLLABORATION WITH HAWAII BADBOY@BADGUYGOODAUDIOREVIEWS

Tangzu Audio has collaborated with HBB to release an upgraded version of their Wu HeyDay IEM. HBB, who is known for their experience and large wired IEM frequency measurement database, helped Tangzu make changes to the bass and highs of the new model based on the sound signature of the previous Wu Zetian earphone. The tuning and optimization done by HBB has resulted in great changes to the new model, and Tangzu Audio hopes that customers will enjoy the new start with this upgraded version.

UPGRADED 14.5MM PLANAR DRIVER

Tangzu x HBB Wu Heyday is equipped with 14.5mm planar driver that features OCC joint wire for the speaker. The new earphone has optimized bass and high frequencies, and the brand is pursuing an overall musical but more neutral and balanced sound with a thicker and more spacious signature. Theoretically, the Wu HeyDay Edition has been improved in many aspects and excels in technicalities, resolution, and details retrieval. Make your music breathe and come alive with the all-new Wu HeyDay Edition.

5-AXIS CNC ALUMINIUM CASE

The case is made of full aluminum, and was processed using a high precision 5-axis CNC machine. Every material used in the manufacturing process of the earphone was carefully selected and undergoes rigorous testing to ensure that the quality meets the brand's expectations. The smooth shells of the earphone are designed to fit easily into most average-sized ears, and are secure and tight. Despite the secure fit, the earphone remains comfortable for extended periods of listening.

4 CORE SILVER PLATED BRAIDED CABLE

Tangzu x HBB Wu includes a 3-in-1 detachable silver-plated cable that is designed to accommodate a wide range of devices while also ensuring balanced sound performance. This means that users can experience high-quality sound with their own preferred cables, or easily change cables if their needs change later on. Overall, this enhancement should provide users with more flexibility and convenience when it comes to using their earphones with different devices.
