The COZOY D1 is a wired ultra-budget IEM that delivers surprisingly mature and balanced sound for around $31. Its 10mm driver provides an engaging listen, while a comfortable fit and solid construction make it a strong value pick in its class. The main caveat is that the included eartips may not provide a reliable seal for all users.

3 source(s) feeding this product's score.
Video reviews we found, each condensed to its verdict. They do feed the HearWiki score, at a measured weight below what a published written review carries.
Reviewers agree the COZOY D1 offers good value for its price, with praise for its build quality, clarity, and tuning that suits certain preferences, though opinions diverge sharply on its treble and comfort.
6:16The reviewer praises the Cozoy D1 for its balanced, bright tuning with good sub-bass and treble clarity, making it a strong budget option for music and gaming. However, he notes significant comfort issues, as the shell shape causes ear pain after extended use, and the bass lacks punch. Overall, he recommends it for beginners due to its tonal balance, but warns about fit.
2:30The 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.
10:33The reviewer compares the COZOY D1 and CCA Phoenix, concluding that the D1 is a superior budget IEM, offering better clarity, resolution, and soundstage, though it lacks the Phoenix's bass punch and carrying case. It is recommended for those seeking a reference-tuned sound, while the Phoenix suits those preferring a warmer, more engaging presentation.
12:09The reviewer finds the Cozoy D1 to be a well-built and attractive budget IEM with a fun, aggressive V-shaped sound, strong bass, and excellent packaging for the price. However, the upper midrange can be shouty and sibilant for some listeners, which is a notable drawback. Overall, it's recommended for those who enjoy a lively, bass-forward tuning and value aesthetics and build quality.
