“DENON PerL Pro AH-C15PL (Black)” This is a wireless earphone featuring aptX Lossless codec support and a personalization function. I purchased it new from Amazon Marketplace around August 2025 and used it occasionally for watching videos and listening to music for about a month and a half. Please note that a receipt is not included. According to the manufacturing date on the back, it appears to have been manufactured in December 2023. Since it was used for a short period, the overall condition is good, in my opinion. There were no operational issues. However, please understand that this is a used item before bidding. All accessories are included. It has been lightly cleaned. *I do read comments regarding price negotiations, but I generally do not reply. I apologize for any inconvenience.
