This is a set of CTM's CE320 and OSNO's 4.4mm balanced cable. The sound quality is excellent for in-ear monitors. Footsteps in games are easy to hear, and the universal fit provides a superb fit. I like it, but I'm selling it because I want to try out other in-ear monitors. ■ Pro-quality sound comparable to custom IEMs ・All models in the CE Series use CTM's proprietary "W.I.S.E. (Wave Integrating Sonic Element) technology." This technology, also used in the manufacturer's high-end models, optimizes the path of sound to the ear, realizing sound faithful to the original sound. ・High-quality drivers selected and arranged in an optimal combination, with CTM's unique tuning. It provides a professional-quality monitor sound, like what musicians on stage hear with custom IEMs. ・Includes a 4-core cable using 99.99% oxygen-free copper conductors. It minimizes signal degradation and contributes to pure sound quality. Further sound quality improvement is also possible by replacing it with an optional premium cable. ■ Unique design developed to fit anyone's ears ・Based on data from the ear shapes of over 20,000 people, we have independently developed a "universal fit design" that fits any ear. It achieves a fit comparable to custom IEMs without the hassle of ear impressions. ・Achieves an outstanding hold that can withstand intense stage performances. Prevents troubles such as accidental detachment from the ear during use. ・Excellent sound isolation, blocking up to 26dB of ambient noise. You can use it comfortably even in a high-volume environment. ・Two types of ear tips, silicone and urethane foam, are included, with a total of 6 pairs in three sizes each: S/M/L. You can freely adjust the fit. #Earphones #IEM #CTM #Gaming #AudioEquipment
