These are fully wireless earbuds packed with features such as long playback time, multi-point connection via LDAC, wireless charging, and active noise cancellation. I've used them about 5 times, but they didn't fit my ears, so I'm selling them. All accessories are included, and the charging cable and S and L ear tips are unused. Retail price: 15,900 yen (official website) Here is the product information from the official website: ANC-equipped fully wireless earbuds [Hybrid Driver] Equipped with two drivers, a balanced armature (BA) and a dynamic driver, they delicately reproduce mid and high frequencies while providing a rich bass for clear and powerful sound. [Noise Canceling Function] Achieves noise reduction of up to -48dB with the ANC function. You can fully enjoy music even in noisy environments. Using the app, you can adjust the noise canceling depth (3 levels) and the level of ambient sound. [Hi-Res Audio Certified] Supports LDAC, dramatically improving wireless sound quality and transmitting up to approximately 3 times more information than conventional technology (SBC). With a wider range than the human audible range, it reproduces sound sources with such detail and fidelity that you can feel the artist's breath and the atmosphere of a live performance. [Up to 56 hours of playback] Up to 17 hours of playback with the earbuds alone, and up to 56 hours with the charging case. Supports two charging methods: wireless charging and USB-C charging. Also supports fast charging, with 15 minutes of charging providing 5 hours of playback. [Wearing Detection Function] When you are wearing the earbuds and playing music, the music will automatically pause when you temporarily remove the earbuds. It will automatically resume playing when you put them back on. *The wearing detection function can be turned OFF through the dedicated app "Edifier ConneX". [Supported Codecs] LDAC / AAC / SBC
