GoFree 2, a wireless earphone supporting LDAC and Hi-Res audio. The left earphone works, but the right one has a charging port issue and won't charge properly. Even if it does charge, the battery runs out in the case, or the device recognizes it as connected via Bluetooth, making it unusable. You might be able to use it as a single-ear earphone. - Model Name: GoFree 2 - Wireless Standard: LDAC - Hi-Res Audio Support: HiRes Audio - Color: Black - Charging Case: Included Thank you for viewing.
