If you want a swimming-proof bone conduction headset with onboard storage and a huge battery, choose RTAPL Bone Conduction; if you need a travel-friendly pair with a charging case, lighter ear-contact feel and a dedicated reading mode, choose Yistao Gen 2.
• RTAPL Bone Conduction — biggest strength: IP68 waterproofing rated to 10 meters, plus 32GB of built-in storage and Bluetooth 6.0 dual-device switching. It's built to survive water, not just sweat.
• RTAPL Bone Conduction — biggest trade-off: It's a neckband design at 26g with a 15-hour single-charge battery. No charging case, so you recharge the headset itself rather than dropping it in a cradle.
• Yistao Gen 2 — biggest strength: A charging case that stretches playtime to 60 hours total, with a 5-minute quick charge giving 1 hour of playback and liquid silicone ear contact that reduces wearing pressure.
• Yistao Gen 2 — biggest trade-off: IP68 covers sweat and rain, not swimming. There's no onboard MP3 storage, and no active noise cancellation listed.
• Choose RTAPL Bone Conduction if: you swim, surf, or want music without carrying a phone.
• Choose Yistao Gen 2 if: you want all-week battery, a case you can pocket, and a softer fit for long listening sessions.
RTAPL Bone Conduction is the more specialized of the two. The headline feature is IP68 waterproofing rated for use 10 meters underwater, which puts it in a different category from most open-ear headsets. If you swim laps or spend time in the water, that rating is the whole point. The 85% ambient noise cancellation is aimed at the same crowd — it's there to cut wind noise and gym chatter rather than to seal you off from the world.
The second thing that sets it apart is the 32GB of onboard memory. That's enough for over 8,000 songs, and it means you can leave your phone in a locker and still have music. You switch between Bluetooth and MP3 mode depending on the session. Bluetooth 6.0 handles the wireless side with stable transmission and seamless switching between two connected devices, so you can bounce between a laptop and a phone without re-pairing.
Who should skip it: anyone who wants a compact charging case, or who mostly listens in short bursts and would rather top up from a case than from a cable. The neckband form factor is also a commitment — it sits around your neck, not in your pocket.
Yistao Gen 2: Who It's For
Yistao Gen 2 takes the opposite approach: it optimizes for portability and comfort over water capability. The charging case is the center of the design. A full charge takes 1.5 hours and gives up to 15 hours of continuous listening, and the case holds four additional full charges for 60 hours total. A 5-minute top-up buys an hour of playback, which is the kind of thing that matters when you're heading out the door and realize you forgot to charge.
The fit story is where this generation improved most. The ear-contact surface moved to liquid skin-friendly silicone, which the brand says reduces wearing pressure by 40% compared to the previous generation's hard plastic and adds friction to stop slipping. Combined with the hook-shaped earpiece and open-ear placement, the intent is a pair you forget you're wearing. For long audiobook sessions or a full workday, that softer contact point is a real difference from a stiffer build.
Audio is handled by the upgraded ToneTerra system, which the brand describes as a 30% increase in volume over the previous generation, paired with SonicBoost 2.0 for bass and highs. There are two EQ modes rather than four: Music Mode for commuting and workouts, and Reading Mode that optimizes vocal frequencies to reduce ear fatigue over long listening sessions.
Connectivity is Bluetooth 6.0 with an instant-link chip, so opening the case pairs the headset without a wait. IP68 keeps sweat and rain out and lets you rinse them clean. Who should skip it: swimmers. IP68 here is a sweat-and-rain rating, not a dive rating, and there's no onboard storage if you want to leave your phone behind.
Side-by-Side: Which Should You Choose?
• Best for battery endurance away from a charger → Yistao Gen 2. 60 hours total with the case beats RTAPL's 15 hours per charge.
• Best for phone-free listening → RTAPL Bone Conduction. 32GB of storage holds over 8,000 songs in MP3 mode.
• Best for all-day comfort → Yistao Gen 2. Liquid silicone contact surface with reduced wearing pressure and a hook shape that sits on the ear.
• Best for long voice content → Yistao Gen 2. Reading Mode tunes vocal frequencies to limit fatigue during audiobooks and podcasts.
• Best for switching between two devices → RTAPL Bone Conduction. Bluetooth 6.0 with seamless switching between two connected devices.
• Best sound customization → RTAPL Bone Conduction. Four EQ modes (Bass, Balanced, Vocal, Swimming) versus Yistao's two.
• Best for pocketable travel → Yistao Gen 2. A charging case roughly 9 x 7 x 2 cm and 75g keeps the whole kit together.
• Best for quick top-ups → Yistao Gen 2. 5 minutes of charging returns an hour of playback.
In my opinion, RTAPL Bone Conduction is the one I'd buy if water is anywhere in your routine. The 10-meter IP68 rating, 32GB of storage and 15-hour battery make it a genuinely self-sufficient training tool — you can swim, leave the phone behind, and still have four EQ profiles to work with. Yistao Gen 2 is the better everyday companion: the case, the softer silicone fit and Reading Mode make it easier to live with if you're mostly running, commuting and listening to audiobooks. If you swim, go RTAPL. If you don't, the case and comfort of the Yistao Gen 2 are worth more day to day. Check the current price on Amazon before deciding, since that's the one variable no spec sheet settles.
how to bone conduction headphones work
They use a bone conduction driver that vibrates against the bone near your ear, sending sound to the inner ear without blocking your ear canal. That's why both of these are open-ear designs — you keep awareness of traffic, gym noise and conversation while listening.
how to wear bone conduction headphones
Set the transducer pads on the bone just in front of your ears and run the band behind your head or around your neck. RTAPL uses a liquid silicone neckband with ear hooks that rest around the neck; Yistao Gen 2 uses a hook-shaped earpiece that sits on the ear with a silicone contact surface.

Pair over Bluetooth 6.0, then use the on-device controls — RTAPL uses push-button and touch controls with four EQ modes, while Yistao Gen 2 switches between Music and Reading modes. RTAPL also runs in MP3 mode from its 32GB of internal storage, so you can listen without a paired phone.
RTAPL Bone Conduction is the one rated for it — IP68 waterproofing rated to 10 meters underwater, with a dedicated Swimming EQ mode. Yistao Gen 2 carries an IP68 rating that covers sweat and rain and allows rinsing, but it isn't built for swimming, and its charging case isn't meant for the water.
