TruthEar made a notable impact with their debut release, the Zero. This success can be attributed to key factors such as a collaboration with the renowned IEM reviewer Crinacle, an underrated 2DD driver configuration, and adherence to the Harman target tuning.

Building on this momentum, TruthEar has expanded its lineup with subsequent releases, including the Hola, Hexa, and the latest addition, the Zero: RED. Each IEM has received acclaim, reflecting a reception that many emerging companies aspire to achieve.
