GoFree 2, high-resolution wireless earphones with LDAC support. The left earbud works, but the right one has a charging port issue and doesn't charge properly. Even if it does charge, the battery runs out in the case, or the device recognizes a Bluetooth connection, making it unusable. You might be able to use it as a single-earbud solution. - Model Name: GoFree 2 - Wireless Standard: LDAC - High-Resolution Audio Support: HiRes Audio - Color: Black - Charging Case: Included Thank you for looking.
