Yistao Gen 2 Bone Conduction, 60H IP68 Open Ear Headphones
About this product
About this item [ Fully Upgraded Bone Conduction Tech for Greater Audio Detail ] – Compared the previous generation, this headphone features the all-new, upgraded ToneTerra system, achieving a 30% increase in volume. Working alongside SonicBoost 2.0 Tech, it delivers a balanced performance of deep bass and clear highs, restoring full and authentic sound details. The specially tuned EQ Mode optimizes mid-range contours to make voice content stand out clearly, providing a more comfortable experience for audiobooks.
[ Fully Upgraded Silicone Material for a Softer Touch and Better Fit ] – We redesigned the ear-contact surface. It has been upgraded to liquid skin-friendly silicone, providing a delicate and soft touch. Compared to the hard plastic of the previous generation, this material not only increases friction to prevent slipping but also reduces wearing pressure by 40%. Once you put them on, you'll forget they're even there.
[ Fully Upgraded Connectivity for Faster, Easier Pairing ] – We upgraded from Bluetooth 5.3 to Bluetooth 6.0, featuring the next-generation Ultra-Fast Instant Link chip. No more waiting—simply open the charging case to achieve an instant connection, with pairing speeds now 2x faster.
[ Stable 60-Hour Total Playtime ] – A quick 5-minute charge provides 1 hour of playback, while a full charge in just 1.5 hours delivers up to 15 hours of continuous listening. Combined with the charging case, you get 4 additional full charges, allowing you to enjoy a full week of power without worry.
[ Stable IP68 Waterproof Rating for Long - Lasting ] – Our bone conduction headphones maintain an IP68 of protection, making them completely immune to sweat and rain. Enjoy worry-free cleaning while ensuring a long-lasting performance.
[ Dual EQ Modes: Switch Between Music & Reading ] — In Music Mode, experience powerful, surging bass and crisp, clear treble—perfect for commuting, sports, and workouts. In Reading Mode, vocal frequencies are optimized for a pure, soft sound that prevents ear fatigue during long listening sessions. No matter which mode you choose, you’ll always have the perfect audio profile for the moment.
Editor's Take
Amazon reviewers and a third-party review blog describe the Yistao Gen 2 as a comfort-first open-ear option with strong battery life, especially for workouts and all-day wear. The most consistent praise is for the 60-hour total playtime claim, the secure fit, and the convenience of keeping ears open for awareness during running or cycling.
Reddit discussion is more skeptical, with users questioning whether the brand’s review profile looks authentic and suggesting the product may have very limited real-world feedback. That makes the overall sentiment harder to verify than for more established audio brands.
A review roundup also highlights the Yistao Gen 2’s IP68 resistance and charging case as standout features, while noting typical bone-conduction tradeoffs like reduced bass and some sound leakage at higher volumes. Overall, the product appears best suited to buyers who prioritize long battery life, open-ear comfort, and outdoor use over premium audio fidelity.
- Amazon reviewers: comfort, usability, and long battery life are the main positives.
- Reddit users: skepticism about review authenticity and limited trust signals.
- Review blogs: strong endurance and IP68 protection, but modest bass and some leakage.
