High-quality driver equipped, re-cableable earphones. Amazon selling price: ¥56,055 - Model name: PERFORMER8 - Plug size: 4.4mm - Accessories: Case Thank you for viewing. This is an authentic product purchased new on Amazon in August of this year. I only listened to the earphones for about 8 hours using my own cable and ear tips, and the other accessories are unused, so I highly recommend it to those considering a new purchase. (The protective cellophane on the cable jack is still attached) In terms of sound, I felt a rich resolution and powerful, energetic "don-shari" (bright and clear) sound, but I think it will change to a more stable sound as the aging progresses. Honestly, I think it's a much more balanced and clear-sounding earphone than the Davinci. Personally, I prefer the calm sound of the performer5+2, which I am currently using. Also, as many reviews mention, the pin insertion on the performer series in general feels stiff, so be careful and insert it gently. Thank you very much. m(_ _)m
