If you want the lightest, simplest open-ear headphone for all-day awareness and you mostly care about comfort, choose Vulxovt Bone Conduction; if you need real battery endurance, a charging case, and a waterproof rating that shrugs off sweat and rain, choose Yistao Gen 2. Both are bone conduction headphones, and both are genuinely usable for the for switch crowd — the kind of person who wants game audio in one ear-free setup without blocking out the room. The difference comes down to how each one is built: one is a bare-bones daily driver, the other is a feature-stacked kit with a case.
• Vulxovt's biggest strength: a genuine bone conduction design with a fully enclosed acoustic cavity, a memory titanium frame, and a very light 27g build that's meant to disappear on your head.
• Vulxovt's biggest trade-off: 10 hours per charge with no charging case, and IPX5 rather than a fully sealed rating — fine for sweat and rain, not for heavy soaking.
• Yistao Gen 2's biggest strength: a charging case that stretches total playtime to 60 hours, IP68 sealing, and dual EQ modes (Music and Reading) so you can shift the tuning to match what you're listening to.
• Yistao Gen 2's biggest trade-off: a bulkier ownership experience — you're carrying a case, and the tuning is more opinionated, which isn't for purists who want a flat, unfussy sound.
• Pick Vulxovt if you want the lightest possible open-ear headphone for running, office work, and daily errands with nothing extra to carry.
• Pick Yistao Gen 2 if you want maximum playtime, the strongest water resistance here, and a case that keeps everything charged and together.
Vulxovt's pitch is simplicity done properly. The core claim is real bone conduction tech paired with a fully enclosed acoustic cavity, which means the sound is delivered through your cheekbones rather than piped into your ear canal. Your eardrums stay untouched, and your ears stay open. That's the whole point of the category, and Vulxovt doesn't dress it up with extra modes or gimmicks.
The comfort story is where it earns its keep. At 27g with a memory titanium frame and soft silicone cushions, this is built for motion — it flexes, it grips, and it's designed to stay put whether you're running, cycling, or sitting through a long workday. Bluetooth 6.0 handles pairing, Type-C charging is universal (no proprietary cable to lose), and the button controls are the kind you can find by feel without looking. IPX5 covers sweat and rain, and the open-ear design keeps you aware of traffic, coworkers, and whatever's happening around you.
Who should skip it? If you're the type who forgets to charge things, 10 hours per charge and 240 hours of standby will eventually catch up with you — there's no case to top it up on the go. And if you want a tunable sound profile or a fully submersible rating, this isn't that product. It's a focused, lightweight daily headphone, not a spec sheet maximalist.
Yistao Gen 2 goes the other direction: it's the fully-loaded version of the idea. The upgraded ToneTerra system claims a 30% volume increase over the previous generation, and SonicBoost 2.0 is tuned for a balance of deep bass and clear highs. The 15mm bone conduction driver and 86 dB sensitivity tell you this is meant to push more air — or rather, more vibration — than a bare-bones unit.
The dual EQ modes are the most interesting part for real-world use. Music Mode leans into bass and treble for commuting and workouts; Reading Mode reshapes the vocal frequencies for a softer, less fatiguing presentation during long audiobook or podcast sessions. That's a genuinely useful split, especially if you listen to a lot of spoken word. Bluetooth 6.0 with an instant-link chip means opening the case pairs it, and the case itself carries four extra full charges — 15 hours per charge, 60 hours total, with a 5-minute top-up giving you an hour back.
The build is upgraded too: liquid skin-friendly silicone on the ear-contact surface, which Yistao says cuts wearing pressure by 40% versus the previous generation's hard plastic. IP68 means sweat, rain, and rinsing it off are all non-issues. The trade-offs are honest ones — you're carrying a case (about 75g and 9 × 7 × 2 cm), the tuning is preset rather than neutral, and the whole package is more involved than a pair of headphones you just toss in a bag.
• Best for all-day comfort and low weight → Vulxovt Bone Conduction (27g, memory titanium frame, silicone cushions).
• Best for battery life → Yistao Gen 2 (15 hours per charge, 60 hours total with the case).
• Best for water resistance → Yistao Gen 2 (IP68 versus IPX5).
• Best for audiobooks and podcasts → Yistao Gen 2, thanks to Reading Mode's vocal-tuned EQ.
• Best for minimalism and travel-light setups → Vulxovt Bone Conduction — nothing extra to carry or charge.
• Best for a low latency headphone for Switch sessions → either one, since both use Bluetooth 6.0; the wired-free, open-ear design keeps you aware of the room while you play.
• Best for spatial audio open ear earbuds for Switch → Yistao Gen 2 if you want the more heavily tuned sound and the case to keep it topped up between sessions.
• Best for simple controls you can operate by feel → Vulxovt Bone Conduction with its button controls, versus Yistao's mode-switching approach.
In my opinion, the Yistao Gen 2 is the stronger buy for most people. The 60-hour total playtime, the IP68 rating, the charging case, and the dual EQ modes give it more ways to fit into your day — and for for switch use, that case means you're not hunting for a cable mid-session. I'd pick Vulxovt instead if weight and simplicity matter more to you than endurance; at 27g with a titanium frame, it's the one you forget you're wearing. Whichever you lean toward, check the current price on Amazon before you commit, since that's the one thing that can tip a close call.
How do bone conduction headphones work?
They vibrate against your cheekbones and pass the sound through the bone to your inner ear, bypassing the eardrum entirely. Both the Vulxovt and the Yistao Gen 2 use this approach, which is why your ears stay open and you can still hear what's around you.
You hook them over your ears so the transducer pads rest against your cheekbones, just in front of your ears — not inside them. The Vulxovt's memory titanium frame and the Yistao's hook-shaped earpieces are both designed to hold that position during movement.
Pair them over Bluetooth 6.0, then use the onboard controls to play, pause, and adjust volume. The Vulxovt uses button controls; the Yistao adds dual EQ modes so you can switch between Music and Reading depending on what you're listening to.
Both connect wirelessly over Bluetooth 6.0, so either works for game audio without covering your ears. If you want the longer runtime and the charging case for back-to-back sessions, the Yistao Gen 2 is the more practical pick; if you want the lightest option, go with Vulxovt.
