I purchased this item new this month and used it once to test the sound. It's in like-new condition. I intended to use it while walking my dog, but I've decided to use something else. Wireless earphones R07, compatible with Bluetooth 5.4 and with a maximum communication range of 10m. - Model: R07 - Bluetooth Version: 5.4 - Maximum Communication Range: Approximately 10m - Compatible Devices: iOS/Android/Windows - Charging Time: Approximately 1.5 hours Thank you for looking.
