Thank you for viewing my product from among many others. You can purchase without commenting. ★Brand New★ Wireless Bluetooth 5.0 Earphone (for one ear) Headset/Microphone/Sports Earphone. Black, 1 piece (for one ear) I myself have been using this for several years, and it's one of my favorite items. The sound quality is quite clear (individual differences apply). The other day, I was devastated when I accidentally washed these earphones in my pants pocket, but when I took them out afterwards, they still worked normally, so I confirmed that they are water-resistant. 【Specifications】 * Bluetooth version: v5.0 + EDR * With microphone function, water-resistant * Transmission range: Approximately 10 meters * Charging time: Approximately 30 minutes * Operating time: Music playback for about 2-3 hours, 40% battery remaining after about 3 hours of use (operating time varies depending on volume and environment) ✳️Charging type: Type B Charging cable and instruction manual are not included. Earphone body only. For appearance and power-on confirmation, I have taken the product out of its individual packaging once and checked it, and then repackaged it in a new zippered individual packaging bag, but please rest assured that it is a brand new, unused item. ■How to Operate■ ① Charge the product body. ② On the connecting device, turn Bluetooth ON. ③ Turn on the power (long press). ④ Search for and connect the device on the device side. ■How to Answer a Phone Call■ When receiving a call, press the button to answer. Press the button again to hang up. Due to being an overseas product, there may be small scratches on the main unit, but there are no problems with the function. * Please be sure to check the function before giving a receipt evaluation.
