TFZ No.3 Ti ・ These are 1DD type earphones from TFZ, a company that is a major player in Chinese earphones, featuring a titanium housing and a diamond diaphragm. ・ TFZ earphones are known for their energetic and bright sound, and this model is the culmination of that. In my subjective opinion, it's a masterpiece among the many Chinese earphones available. It pairs well with rock music, and excels with guitar rock and techno. ・ I tested it by connecting it to a portable amplifier before listing it, and it works without any problems. ・ The main unit has some minor scratches and dullness from use. It is not like new, so please be aware of this when purchasing. ・ Price: Approximately 45,000 yen ・ Included items: Main unit, original box, cable (unused), ear tips (unused), instruction manual
