【SONY Wireless Earphones WF-1000XM3】 I purchased these to help my child (a high school girl) deal with sounds she dislikes (like coughing and sniffling). However, they didn't fit her ear canals well, and the noise cancellation wasn't as effective as hoped. She didn't use them much and they were stored away, but I'm selling them now as part of a decluttering effort. There are some minor scratches on the case lid from use, but the earphones and ear tips are in good condition, and the box is also clean. I tested the earphones before listing them, and they are working perfectly. Returns are not accepted. Thank you for your understanding regarding home storage. ●Product Description● 【High-Performance Noise Canceling】 Achieves high-performance noise canceling with the "High-Quality Noise Canceling Processor QN1e" and "Dual Noise Sensor Technology," which uses two microphones for highly accurate sound collection. 【Stable Connectivity and Reduced Latency During Video Viewing (*)】 Equipped with a new Bluetooth chip, this model uses a method that simultaneously transmits to both the left and right units from the music playback device.
