Only those who have completed identity verification are allowed to purchase. I have already set the price lower than the used market price at e-earphone, so please do not expect a discount. If it doesn't sell, I will continue to use it myself. If you wish to negotiate a price reduction, please submit a price reduction request instead of negotiating in the comment section. I swear this is not a counterfeit product that is often circulated in the flea market. Made in Germany, production lot. Purchased at e-earphone in 2023. No sound issues. I was using it without any problems until just before. In addition to the included genuine cable, I will include two 4.4mm balanced cables specifically for the IE900. One is ivipQ, and the other is a handmade cable purchased from a custom cable maker. Everything in the photos is included. Only the included genuine 2.5mm balanced cable is missing, but the 3.5mm and 4.4mm balanced cables are included. No operational problems. This is a used item, so please refrain from purchasing if you are overly concerned about the appearance. Please check the condition in the photos. I cannot include the invoice in principle because it contains personal information, but I can provide the part that shows the purchase date and order number. Please let me know if you would like this. This is an earphone with many counterfeits, so returns are not accepted to prevent swapping. Please purchase only if you agree to this. #Sennheiser #Sennheiser #WiredEarphones - Brand: Sennheiser - Model: IE 900 - Supports Hi-Res Audio: Yes - Accessories: Re-cableable earphones, 2 cables - Country of Manufacture: Germany Thank you for viewing.
