Yistao LibreFit Pro B8 Open Ear Headphones Bluetooth 6.0 60h IP68 obsidian gold

Open-Ear Design for Active Use

The Yistao LibreFit Pro B8 uses open-ear bone conduction so you hear audio while staying aware of traffic or instructors. It suits runners, cyclists and yoga practitioners who need situational awareness. Swimmers and indoor trainers benefit from the IP68 rating. Buyers who want noise isolation or deep sub-bass impact should choose a sealed in-ear model instead.

ToneTerra and SonicBoost 2.0 Audio Tuning

The upgraded ToneTerra system raises maximum volume by 30 percent over the previous generation. SonicBoost 2.0 technology balances low frequencies with clear highs. A dedicated EQ mode lifts mid-range contours so voices in podcasts and audiobooks stand out. No active noise cancellation is included, so ambient sound always mixes with playback.

Bluetooth 6.0 Instant Pairing

Opening the charging case triggers an instant Bluetooth 6.0 link that pairs twice as fast as the earlier 5.3 implementation. Liquid skin-friendly silicone replaces hard plastic, cutting wearing pressure by 40 percent and adding grip so the units stay put during movement. The case stores 60 hours of total playtime and recharges fully in 2 hours 5 minutes.
