The Sony WF-1000XM4 In-Ear Wireless Headphones in Black offer a sleek and stylish design perfect for on-the-go use. With Bluetooth technology, these earbuds provide a seamless wireless experience. Featuring noise cancellation and a built-in microphone, these headphones deliver superior sound quality and convenience. The double earpiece design ensures a comfortable fit, making them ideal for long listening sessions. Released in the 2020s, the Sony WF-1000XM4 model is a top choice for those looking for high-quality, portable audio. this is a used pair, I replaced I think the right one a couple of years ago after losing it, and bought an XM5 as well. these have been used maybe two or three times since then, so no need to keep them any more.
