What sets the FreeBuds 6i apart is the smart Active Noise Cancellation 3.0, which was previously featured in the Pro series. The headphones monitor ambient noise every 2.6 microseconds and dynamically adjust settings.
Improvements include a set of noise-cancelling microphones, optimized ear pads made of tactile silicone for better fit and comfort, and three microphones per earbud. Compatible with LDAC HD audio codec and High-Definition Audio Wireless certification
Working time: Up to 35 hours of playback with the charging case, up to 8 hours of playback on a single charge without the case. A 10-minute charge provides up to 4 hours of playback.
