The Fineblue F-V3 uses Bluetooth 4.1 (CSR chipset) to provide wireless stereo music playback (A2DP) and can maintain connections to two phones simultaneously for calls and audio switching.
Designed with noise reduction and echo suppression technology, the earphones include an iPhone battery level display and support voice prompts in English or Chinese. A one-button power-on pairing remembers and reconnects to devices, offering about 5 hours of talk time and roughly 7 days of standby.
