2:30The Cozoy D1 & D2 IEMs Are Bad
The reviewer finds the Cozoy D1 and D2 IEMs disappointing due to a significant peak at 11 kHz and poor high-frequency extension, which persists even after EQ. The D1 is preferred for its closer-to-target stock tuning, but both are ultimately not recommended because the treble issues cannot be fully corrected.
