SENNHEISER wireless earbuds, MTW3 in black. In my subjective opinion, the battery doesn't seem to have degraded much, and there are no issues with charging, music playback, touch sensor, transparency mode, noise cancellation, app connection, etc. These are high-performance earbuds that can handle all genres, with high-resolution sound quality and a wide soundstage. You'll understand how good they sound when you listen to them. I purchased these used, and the included ear tips and ear fins may or may not be present, and the sizes are unknown, so please consider them as extras. The charging cable is not included. I have cleaned them simply, but if you are particularly concerned, please clean them yourself. Please check the images for the condition of the product, but there is some lint on the fabric parts. Returns are not accepted to prevent product substitution. Sennheiser Model Name...MOMENTUM True Wireless 3 Other features...Noise Cancelling #Nanashi's Audio Listings
