This is the KZ "ZSN PRO2" earphones. The item is a brand new, unused black version without a microphone, as shown in the title photo. I recently purchased it and have been carefully storing it on a shelf at home. I do not have any pets, and I am a non-smoker. There may be some minor dents or imperfections on the packaging. I am also listing this item on other sites, so please forgive me if it sells out. Returns and cancellations are not accepted. For initial defects or missing items, please contact the manufacturer's support. I will ship via Yu-Packet Post as quickly as possible. Due to packaging size constraints, the packaging will be simple. If the items are small, I can combine shipping, so please inquire via comments. Please feel free to ask any other questions.
