Thank you for viewing! (^^) This is the high-quality wireless earbuds "MeloBuds N70" from QCY. I own two pairs, and this one was purchased for storage and has been kept unopened at home since then. It is a new, unopened item, still in its original packaging film from when it was purchased. Model: QCY MeloBuds N70 Hi-Res AUDIO WIRELESS Certified LDAC codec support 3-mic adaptive ANC (noise canceling) Dual acoustic driver equipped Wireless charging compatible Bluetooth 5.3 / Fast Pair compatible Continuous playback time: Approximately 10 hours (up to approximately 42 hours with the case) *Since it is unopened, the operation has not been confirmed. Please contact the manufacturer for initial defects, etc. I will sell it to someone who understands home storage.
