New, unused SONY wireless earbuds WF-C710N Black New, unused, and unopened, I had been storing them. However, I had to open them to take photos. I apologize for this. To prevent replacements, returns are not accepted. Please understand this before purchasing and considering. The SONY WF-C710N are fully wireless earbuds equipped with high-performance noise-canceling features. The main features are as follows: Noise-canceling function: Adopts dual noise sensor technology, allowing you to immerse yourself in music even in noisy environments such as trains and cafes. It also features an "Ambient Sound (External Sound Intake) Mode" that allows you to hear the surrounding sounds. Long Battery Life: With noise canceling ON, the earbuds alone provide up to approximately 8.5 hours of playback, and up to approximately 30 hours with the charging case. High Sound Quality: Despite their small size, they use Sony's proprietary 5mm drivers, achieving balanced and clear sound quality. They also feature DSEE technology, which upscales compressed audio to CD quality. Convenient Features: Multipoint Connection: Supports multipoint, allowing connection to two devices simultaneously. For example, you can listen to music on your smartphone while answering incoming calls for online meetings on your PC. Wearing Detection Function: When you remove the earbuds from your ears, the music automatically pauses, and it resumes when you put them back in. Water-resistant Performance: Water-resistant, so you can use them without worrying about sweat or rain. Charging Port: Uses USB Type-C. With AI technology, the high-precision voice pickup technology also provides high call quality, making it suitable for online meetings.
