How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a gaming-friendly open-ear headset with a dedicated low-latency mode and voice-assistant control, choose LOBKIN Bone Conduction Headphones; if you need maximum playtime and a bundled set of earplugs for the loudest environments, choose Spinosa Bone Conduction Headphones.
• LOBKIN's biggest strength: Dual audio modes — a Game Mode tuned for low latency plus a Music Mode — backed by Bluetooth 5.4, a 16mm driver and voice-assistant access.
• LOBKIN's biggest trade-off: Shorter rated playtime (10 hours) and a 2-hour charge, so heavier users will plug in more often.
• Spinosa's biggest strength: Up to 12 hours of playtime and a fast 90-minute charge, plus earplugs in the box for noisy settings.
• Spinosa's biggest trade-off: No gaming/low-latency mode and no voice-assistant feature are listed; it's built purely around long, steady outdoor sessions.
• Pick LOBKIN if you split your time between workouts and gaming, want a lighter 28g build, and like the idea of voice control from the earpiece.
• Pick Spinosa if your priority is staying powered through the longest rides, hikes and gym blocks, and you want earplugs included for windy or traffic-heavy routes.
LOBKIN's X25 is the more feature-dense of the two. The headline is its dual-mode Bluetooth 5.4 setup: a Game Mode for ultra-low latency and a Music Mode for everyday listening, switchable depending on what you're doing. That's unusual in the bone-conduction space — most open-ear headsets are tuned for one job only. On top of that, LOBKIN lists voice-assistant access (double-click the power button once paired) and dual-device connection, so you can hop between a phone and a second device without re-pairing from scratch.
The audio hardware is a 16mm bone-conduction driver with a 20Hz–20kHz frequency range, an 8-ohm impedance and 90dB sensitivity. LOBKIN frames it around "crystal clear stereo sound" and a built-in mic for calls, and the spec sheet backs the general shape of that claim: a larger driver than Spinosa's 15mm unit. In my opinion, the bigger driver is the more interesting number here if you care about fullness at moderate volume — though bone conduction is inherently a different listening experience than in-ear audio, so don't expect isolation-style bass from either brand.
Buy it if you want one headset that covers gym sessions, runs and late-night gaming, and you value the lighter build and voice-assistant shortcut. Skip it if you need the longest possible runtime between charges, or you want earplugs included for very loud roads.
Spinosa Bone Conduction Headphones: Who It's For
The Spinosa M3 is the endurance pick. Its standout number is battery: up to 12 hours of playtime on a single charge, with a 90-minute charge time — that's two more rated hours than LOBKIN and a noticeably quicker top-up. For long weekend rides, multi-hour hikes or back-to-back gym days, that gap is the whole story. It also ships with earplugs, which is a smart inclusion: pop them in and the bone-conduction output becomes much easier to hear in wind or heavy traffic, while your ear canals stay open to the sounds that matter for safety.
Audio is handled by a 15mm bone-conduction transducer with round pads, an 8-ohm impedance, a 20Hz–20kHz range and a listed 40-millisecond audio latency. Bluetooth is also 5.4, with a stated range of 33 feet. The controls are straightforward and physical: long-press the power button for on/off, short-press for calls and play/pause, and use the plus/minus buttons for volume and track skipping. No app, no modes to think about.
Build-wise it's ABS with a flexible wraparound band, and it comes in black with a small white carton carry case (listed at 5.7 inches, 14.2g). The headset itself is listed at 1.06 ounces — roughly 30 grams — so the two are in the same weight class, though Spinosa is marginally heavier on paper. It's rated IPX5 for sweat and splash resistance and carries a 1-year manufacturer warranty.
Buy it if runtime and simplicity are your priorities, and you want earplugs in the box for loud environments. Skip it if you want a gaming mode, voice-assistant control, or the larger 16mm driver.
• Best for battery life → Spinosa Bone Conduction Headphones (up to 12 hours vs 10).
• Fastest recharge → Spinosa Bone Conduction Headphones (90 minutes vs 2 hours).
• Best for gaming / low latency → LOBKIN Bone Conduction Headphones (dedicated Game Mode).
• Best for everyday music listening → LOBKIN Bone Conduction Headphones (Music Mode plus a 16mm driver).
• Best for hands-free voice control → LOBKIN Bone Conduction Headphones (voice assistant via double-click).
• Best for noisy outdoor routes → Spinosa Bone Conduction Headphones (earplugs included for extra perceived volume).
• Lightest on paper → LOBKIN Bone Conduction Headphones (28g vs roughly 30g).
• Simplest controls → Spinosa Bone Conduction Headphones (plain physical button layout, no modes).
Both are IPX5, both use Bluetooth 5.4, both share an 8-ohm impedance and a 20Hz–20kHz range, and neither offers active noise cancellation — that's the nature of open-ear design, and neither brand claims otherwise. Neither should be used for swimming.
If I were buying one of these for myself, I'd take the LOBKIN Bone Conduction Headphones. The dual-mode Bluetooth 5.4 setup, the voice-assistant shortcut, the 16mm driver and the lighter 28g frame make it the more versatile headset for someone who mixes workouts with gaming and calls. Ten hours is still plenty for a normal training week. I'd only switch to the Spinosa Bone Conduction Headphones if runtime is genuinely non-negotiable for me — long rides, all-day hikes, minimal charging downtime — in which case the extra two hours, the 90-minute charge and the included earplugs make it the better tool. Check the current price on Amazon before deciding, since value can shift on either side.
For pure running, both work — they're both IPX5, both Bluetooth 5.4, both open-ear. Spinosa gives you more battery and earplugs; LOBKIN gives you a lighter frame and a music/game mode switch. Long-distance runners will feel the battery gap more.
Can I use either one for swimming?
No. Both are rated IPX5, which covers sweat, rain and splashes only. LOBKIN states outright that its headset isn't a swimming headphone and shouldn't be used underwater, and Spinosa's rating is the same class. For pool use you'd need a dedicated swimming model.
Neither brand publishes lab measurements, so I'm going on driver size and features. LOBKIN lists a 16mm bone-conduction driver versus Spinosa's 15mm, and adds a Music Mode — in my opinion that gives LOBKIN a slight edge on paper for music listening. Spinosa counters with earplugs, which can make its output easier to hear in loud environments.
No — that's the point of open-ear bone conduction. Both keep your ear canals open so you can hear traffic and surroundings, and neither lists noise cancellation as a feature. If you want isolation, the Spinosa's included earplugs are the closest either product gets.
Spinosa lists a 90-minute charge time; LOBKIN lists 2 hours. Spinosa also rates playtime higher at up to 12 hours versus LOBKIN's 10.
