How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want open-ear earbuds you can wear with glasses and forget you have on, choose Xmenha Open Ear Earbuds; if you need maximum battery life, tougher water resistance and a true bone-conduction fit for hard training, choose Acjohtin Bone Conduction Headphones.
• Xmenha biggest strength: ultra-fine memory titanium ear hooks with a charging case that extends total playtime to roughly 35 extra hours, and Bluetooth 5.3.
• Xmenha biggest trade-off: the buds themselves run only 5–7 hours per charge, and the fit depends on hook geometry rather than a locked-in bone-conduction frame.
• Acjohtin biggest strength: 16 hours of continuous playback on a single charge, Bluetooth 6.1 with 60ms low latency, and an IP67 rating for sweat, light rain and splashes.
• Acjohtin biggest trade-off: no charging case, no noise control, and a 1.5-hour full recharge that makes topping up slower than a quick case swap.
• Pick Xmenha if you wear glasses, want a discreet hook-style bud with a case, and prefer awareness plus a lighter, more everyday look.
• Pick Acjohtin if you run, cycle or train hard, want the longest single-charge runtime, and need real water and dust protection.
The Xmenha pair is built around one idea: get audio into your ears without blocking them, and do it without fighting your glasses. The ear hooks are ultra-fine memory titanium — the brand describes them as barely thicker than ten strands of hair and almost undetectable to the touch. That's a design choice with a real payoff. If you wear prescription frames, thick arms can make clip-on and hook-style buds uncomfortable within twenty minutes. Thin memory metal tends to slide between your temple and your glasses arm instead of pressing on it. In my opinion, that's the single most compelling reason to pick this model.
On the audio side, Xmenha leans on "AIR bone conduction" rather than true bone conduction. Practically, that means the sound is delivered near the ear opening, so you hear your music and your surroundings at the same time. That's genuinely useful for runners on shared paths, cyclists in traffic, and anyone working in an office who still needs to hear a colleague call their name. The waterproof, sweat-proof build covers rain, sweat and indoor workouts, and Bluetooth 5.3 keeps the wireless link current. The built-in microphones use physical noise reduction plus acoustic noise cancellation, so calls should hold up in noisy places.
Battery is where you need to read the fine print. The buds give 5–7 hours per charge, and the charging case adds about 35 hours on top. The case itself recharges in roughly an hour. So the total package is generous, but a single session is not marathon-length. If you want one charge to carry you through a very long day, that's a limitation.
Buy it if: you wear glasses, you want a discreet hook-style open-ear bud, you value the case for total runtime, and you split your listening between runs, walks and desk work.
Skip it if: you train for hours at a stretch without a case nearby, or you specifically want the bone-conduction sensation of sound traveling through your cheekbones. Xmenha's own materials are upfront that this is not a bone conduction headphone — it's an open-ear alternative.
Acjohtin takes the opposite approach. This is a genuine bone conduction design with a fully enclosed cavity, transmitting sound through your cheekbones via a 16mm bone conduction driver rated at 90dB sensitivity. The ear canals stay completely open, which is the whole point: awareness first, audio second. The brand lists running, cycling and hiking as the target activities, and the spec sheet backs that up.
The headline number is 16 hours of continuous playback. That's more than double what the Xmenha buds manage per charge, and there's no case involved — just the headset. Fast charging fills it from 0% to 100% in about 1.5 hours, and a 10-minute top-up buys roughly 1.5 extra hours. That combination matters if you're the kind of person who forgets to charge until you're lacing up. The trade-off is that you can't swap in a fresh case mid-day, so the 1.5-hour full charge is your only recovery route.
Durability is the other standout. The IP67 rating handles heavy sweat, light rain and splashes, with a nano-hydrophobic coating and a sealed acoustic structure adding a second layer of protection. There's even a moisture detection alert that warns you if the charging port is wet. Read the limits carefully, though: Acjohtin explicitly says not to use these in heavy rain and not to swim with them. IP67 is excellent for workouts, not for pool laps.
Comfort comes from a 28g integrated frame with memory metal wire and a biomimetic ear-hook shape that adapts to your head. The open design keeps airflow moving, which the brand frames as ear-health friendly — no pressure, no plugged feeling. For calls, a dual wind-resistant mic array plus AI noise reduction claims to filter out 96.5% of background noise, and Bluetooth 6.1 delivers instant pairing, 60ms latency and a 33-foot range.
Buy it if: you want long single-charge sessions, you train outdoors in sweat and light weather, you care about low latency for gaming or video, and you like the bone-conduction feel.
Skip it if: you want a charging case, you need active noise control, or you'd rather have a lighter hook-style bud you can pocket. Also skip it if you wear thick-armed glasses and want the thinnest possible temple clearance — the integrated frame is more substantial than Xmenha's wire hooks.
• Best for battery life → Acjohtin. 16 hours continuous beats Xmenha's 5–7 hours per charge.
• Best for total runtime with a case → Xmenha. The case adds roughly 35 hours of top-ups.
• Best for glasses wearers → Xmenha. Ultra-fine memory titanium hooks are designed to sit under or beside frames.
• Best for water and dust protection → Acjohtin. IP67 with a nano-hydrophobic coating outranks a general waterproof claim.
• Best for low latency and gaming → Acjohtin. Bluetooth 6.1 with 60ms latency and a 33-foot range.
• Best for calls in wind → Acjohtin. The dual wind-resistant mic array plus AI noise reduction targets exactly that.
• Best for everyday discretion → Xmenha. A lighter plastic build with a case is easier to carry and less obviously "sports gear."
• Best for true bone conduction → Acjohtin. A 16mm bone conduction driver versus Xmenha's AIR-conduction approach.
If I were buying for myself and my priority were all-day training and weather, I'd take the Acjohtin Bone Conduction Headphones. Sixteen hours per charge, IP67, Bluetooth 6.1 and a 28g frame make it the more serious sports tool, and I'd rather have a single long-lasting headset than juggle a case. That said, if you wear glasses daily and want something lighter and more casual, I'd point you to the Xmenha Open Ear Earbuds — those titanium hooks are the feature I'd miss most. Match the pick to your routine, then check the current price on Amazon before deciding.
No. Xmenha describes its design as "AIR bone conduction," meaning sound is delivered near the ear opening rather than vibrated through bone. Acjohtin uses a true 16mm bone conduction driver, which is the physical difference between the two.
Xmenha gives 5–7 hours per charge with about 35 extra hours from the case, and the case refills in roughly an hour. Acjohtin gives up to 16 hours continuous with a 1.5-hour full charge and a 10-minute quick charge for about 1.5 hours of playback.
Xmenha is the better bet. Its memory titanium hooks are extremely thin by design, so they can sit alongside glasses arms without pressure. Acjohtin's integrated memory metal frame is sturdier, which some glasses wearers find less forgiving.
Not with either pair as advertised. Acjohtin carries IP67 for sweat, light rain and splashes but explicitly rules out heavy rain and swimming. Xmenha states a waterproof, sweat-proof build for sweat and rain, without a swimming claim.
