The C5 truly wireless liberates your music from cable mess. Equipped with 6 mm rare-earth-magnet drivers that produce deep bass and sparkling mid-range sound, these snug-fitting earphones feature Bluetooth 5.0 wireless technology and are compatible with the AAC codec. Continuous playback extends to five hours while the supplied Quick Charge carry-case refreshes the earphones for another hour?s entertainment in just 15 minutes. Total on-the-go playback is 15 hours. Simple button-presses enable hands-free music and call management, while Ambient Awareness mode, Auto Pairing, Auto On/Off, IPX5, and voice-assistant access highlight user-friendliness.
