Pros: Wonderful clarity and balance, with well-controlled and textured deep bass.
Cons:The cable is of inferior quality, and the microphone has low volume.
The packaging exudes the typical budget IEM aesthetic found with brands like KZ or the more affordably priced offerings from KBEAR. Inside, there are some tips and a slender cable. The DC02 is available with or without a microphone and comes in either black or silver. The comfort level of the SOLO is superb, offering good isolation, and the silicon-made CCZ fin on the back is great. The IEM fits well into the ear and is well-crafted.
Sound: The lower end of the Solo DC02 is enhanced, offering a quick and deep bass response with fine texture and control, without overshadowing the other frequencies. The mid-bass hits well, but I believe the sub-bass is slightly more dominant. Listening to "Laid to Rest" by Lamb of God is one of my test songs; the bass kept up nicely and was enjoyable.
The midrange is crisp, exhibiting slight warmth and fullness in the lower mids, while the upper mids are bright and distinct. Vocals are well-balanced, with placement that is neither too forward nor too recessed.
The high frequencies offer a pleasant amount of sparkle, leaning more towards a balanced and safe profile, yet they still deliver a natural and clear sound. The soundstage is impressive, providing a broad and open sound with excellent imaging and detail. While it may not be the best, it is outstanding for its price range.
In a nutshell: The CCZ Solo DC02 is a reliable and outstanding IEM for its price, offering both solid technical performance and enjoyable, yet safe tuning.
