This is the CTM CE220. The CE220 is an in-ear monitor equipped with two carefully selected balanced armature (BA) drivers, delivering sparkling high frequencies and punchy bass. You can enjoy high sound clarity and powerful sound. Regarding the condition, I purchased it in June 2025 and used it several times. It works without any problems, and there is no noticeable dirt, so it's in good condition. Accessories: Instruction manual, ear tips, standard plug adapter CTM logo zipper case All items are included.
