2025-08-28This is basically unlistenable. Requires EQ, but is fine with it. Jaytiss Youtube Channel

Basically the modded Zero with slight more bass. Most vocal forward out of the $20 sets. Jays Audio Youtube Channel

Tangzu Wan Er reviewed by: Shuwa-T
Comment: It's literally $20, recommended to buy when starting out or as a beater set. Probably the most balanced sounding at its price Average tech like its other counterparts, bass is less controlled
