Chord & Major Jazz-Major 7'13 wired earphones. I purchased these from e-earphone several years ago and have been using them. I am selling them because I haven't had a chance to use them in recent years. The jack was damaged, so I had it repaired at e-earphone, and the cable length is slightly shorter as a result. I have disposed of the box, so only the pouch and the main unit are included. Please understand that these are used items before purchasing. The following is a product description: "Major7'13" is an earphone developed with the characteristics of jazz music in mind. It emphasizes the bass tones, expresses the vocal magnetism of the mid-range, and provides a sense of presence and spaciousness. The relaxed feeling that is characteristic of jazz music comes from the resonance and rhythm of each instrument. The singer's voice is also recognized as an instrument, and they compete with the instruments in turn, echoing each other. Common instruments in jazz music include the piano, bass, jazz drums, saxophone, and guitar. The Chord & Major "Major7'13" earphones reproduce the resonance of the low frequencies, such as the bass and jazz drums, and the smooth sound expression of the saxophone, conveying the emotions in the voice all at once. ◎Specifications Sensitivity: 94dB/mW Frequency Response: 20～20,000Hz Impedance: 16Ω Cable Length: 1.2m Plug: Stereo Mini Original Price: ¥20,166
