※ This is a set sale, and we cannot accommodate requests for individual sales. I am selling these because I have purchased and only use high-end earphones in the 100,000 yen class, such as the Ziigaat ARETE. All accessories are complete, and I have used my own ear tips, so the included ones are unused. Therefore, the earphone housings have only been used slightly. (None of them have been used for more than an hour. I bought a large number of earphones at once, so I didn't get to use many of them...) I think of this as a beginner's set for those looking for earphones for FPS games. (Planar earphones offer a different experience with sound onset (detecting footsteps within explosions), while intra-concha earphones provide a sense of spaciousness. This set is ideal for those who want to try both canal and intra-concha types.) ※ Of course, you can still hear footsteps clearly with these sets. Wired Earphones ・TRN EMX: Intra-concha type, 3.5mm, 4.4mm, and 2.5mm switchable (Purchased for approximately 4,000 yen) ・KZ PRX: Planar (planar diaphragm) type, 3.5mm unbalanced (Purchased for approximately 8,000 yen) Re-cable (Purchased for approximately 4,500 yen) ・QDC: JSHiFi-Obsidian (4.4mm balanced) Can be used with PRX and EMX. The graphene cable improves sound separation, allowing you to detect footsteps hidden in explosions. I think it pairs well with planar earphones. Thank you.
