• Butyoef Open Ear Headphones — biggest strength: a true open-ear, air-conduction design with silicone ear hangers and a full IPX7 waterproof rating, so nothing plugs your ears and sweat or rain isn't a worry.
• Butyoef Open Ear Headphones — biggest trade-off: it's a two-ear open design, so if you specifically want one ear free for a phone or a dispatcher, it isn't that.
• Atheewon Headset V5.3 — biggest strength: a single-ear headset with a boom mic, CVC 8.0 + ENC noise reduction, and a huge 120-hour figure tied to its charging case.
• Atheewon Headset V5.3 — biggest trade-off: the boom-arm, over-ear hook form factor is more about calls than about immersive music, and it's a different kind of listening than an open panoramic soundstage.
• Who each is for: Butyoef for anyone who wants both ears open and protection from water; Atheewon for drivers, truckers and call-heavy workers who live on one ear.
The Butyoef Open Ear Headphones are built around one idea: keep your ears open. Instead of pushing a tip into your ear canal, they hang on a silicone ear hanger and deliver sound by air conduction. That means no plugged feeling, no pressure on the eardrum, and the natural awareness of what's going on around you stays intact. If you've ever pulled an earbud out at a crosswalk or a front desk just to hear someone, this is the category that solves that for you.
The sound side leans on ACS panoramic audio, which the spec sheet describes as simulating a 360-degree stereo surround field, plus DireectPitch directional sound field technology aimed at keeping audio pointed at you rather than leaking outward. That privacy angle matters in an office or on a train. There's also AI call noise cancellation using bidirectional acoustic noise cancellation and an adaptive beam that calculates where the caller's voice is coming from, so calls stay usable in noisy rooms. The body is described as ultra-lightweight (1.2 ounces total) with skin-friendly silicone to cut friction against the ear contour, and the fit is pitched as stable enough to stay put during movement.
Who should skip it: if you want one ear completely free for a separate phone, or you need a boom microphone positioned right at your mouth, this isn't the shape for you. And if you want maximum isolation from the world, an open design is the wrong tool by definition.
Atheewon Headset V5.3: Who It's For
The Atheewon Headset V5.3 is the opposite personality: it's a single-ear Bluetooth headset with a rotating hook and a boom arm, and everything about it points at people who talk for a living. Drivers, truckers, dispatchers, delivery workers, and anyone on calls all shift long. The included ear tips come in three sizes (S/M/L), the ear hook rotates 180 degrees and the boom arm adjusts 270 degrees, and it can be worn on either ear — so it's designed to be dialed in and then forgotten.
The call technology is the core of the pitch. It pairs CVC 8.0 with ENC dual noise reduction, and the spec sheet claims it reduces up to 60% of background interference by detecting ambient noise and pulling your voice out of it. For audio, it uses 13.0mm low-distortion composite dynamic drivers with a high-resolution decoder supporting AAC and SBC, which is a serious spec for a headset of this shape. Bluetooth 5.3 handles pairing with phones and tablets, with a stated 15-meter open-environment range.
Battery is where this one flexes: a 430 mAh battery, up to 120 hours of standby with the charging case, up to 20 hours of talk time, and a full charge in 1.5 hours via Type-C. There's an LED digital display on the case showing remaining capacity, separate volume and media buttons, and one-press access to Siri or Google Assistant. It's also IP7 waterproof, which covers sweat and rain for running, the gym, or outdoor work.
Who should skip it: if your priority is music quality with both ears and a wide soundstage, a single mono headset isn't the experience you're after. And if you dislike boom arms or something resting on your ear for hours, the open-ear hanger style will feel lighter.
Side-by-Side: Which Should You Choose?
• Best for open-ear comfort and awareness → Butyoef Open Ear Headphones. Silicone hangers, no ear canal plugging, and a 1.2-ounce body.
• Best for call-heavy jobs → Atheewon Headset V5.3. CVC 8.0 + ENC dual noise reduction and a boom mic built for voice.
• Best for immersive stereo music → Butyoef Open Ear Headphones. ACS 360-degree panoramic sound with 20 Hz–20 kHz and 50 ms low latency.
• Best for workouts and wet weather → Butyoef Open Ear Headphones. Full IPX7 waterproofing beats the Atheewon's IP7 sweat-and-rain coating for submersion-level protection.
• Best for one-ear freedom on the road → Atheewon Headset V5.3. Wearable on either ear with a rotating hook, so one ear stays open to traffic and surroundings.
• Best for touch controls and status display at a glance → Butyoef Open Ear Headphones. Touch control plus an LED display and three power levels on the case.
• Best for button-based simplicity → Atheewon Headset V5.3. Push-button control with dedicated volume and media keys, no touch guessing.
In my opinion, the Atheewon Headset V5.3 is the smarter buy for most people who compare these two, because its job is narrower and it does that job thoroughly: long calls, big battery numbers, and a mic system tuned for voice. The 120-hour standby figure, 20-hour talk time, and 1.5-hour charge make it the one I'd hand to a driver or anyone who lives on the phone.
But if your priority is open-ear listening with real water protection, I'd pick the Butyoef Open Ear Headphones instead. IPX7, a 1.2-ounce hanger design, and panoramic stereo are a better match for workouts, travel, and staying aware of your surroundings.
FAQ
are ipx7 earbuds waterproof
IPX7 is a waterproof rating, not just water-resistant. It means the device is tested to survive immersion in water up to about 1 meter for 30 minutes. The Butyoef Open Ear Headphones carry this IPX7 rating, so sweat, rain, and accidental dunks are covered.
Technically IPX7 covers short immersion, so a shower is within the rating's range. That said, soap, shampoo, and steam aren't the same as clean water, and no manufacturer guarantees against those. The Butyoef's IPX7 rating gives the most headroom here; the Atheewon's IP7 covers sweat and rain rather than prolonged soaking.
what's the battery difference between these two headsets
The Atheewon Headset V5.3 runs a 430 mAh battery rated for up to 120 hours of standby with its case and about 20 hours of talk time, charging in 1.5 hours. The Butyoef's spec sheet lists a 300 mAh charging case with three power levels but no hour figure, so if raw endurance numbers matter to you, the Atheewon is the more documented option.
which one is better for driving and trucking
The Atheewon Headset V5.3, clearly — it's a single-ear headset with a boom mic, a 180-degree rotating hook, a 270-degree adjustable arm, and either-ear wear, all aimed at hands-free calls on the road. The Butyoef is a two-ear open design better suited to meetings, travel, and workouts.
