These are the popular SONY wireless earbuds, the "WF-C700N". Recommended for those who have lost an earbud. Purchasing only one earbud is not recommended as pairing may not be possible due to version differences, so purchasing both earbuds is recommended. *Case not included. Left and right earbuds: Touch operation sound (touch sound) confirmed. Music playback is also okay for about 3 hours, and they still have plenty of battery life. Sound quality is also not a problem. Appearance: Lightly cleaned and disinfected with alcohol, in relatively clean condition. Although there may be some scratches due to being a used item, they are in generally good condition overall. We are looking forward to your purchase if you understand this.
