I am selling these earphones because I bought a new pair. The battery life of the left earphone has decreased to about 1 hour, and sometimes the connection cuts out, so please consider this as a defective (junk) item. However, they work perfectly fine for short periods of use at the moment. Original price: Approximately 10,000 yen Used for: Approximately 2 years Noise canceling and ambient sound mode also work without any problems. ＝＝The following text was generated by AI＝＝ AVIOIT TE-D01m black wireless earphones with touch control function. - Brand: AVIOIT - Model: TE-D01m - Color: Black - Design features: With touch control - Case type: With charging case Thank you for viewing.
