• Butyoef's biggest strength: a true open-ear, air-conduction design with silicone ear hangers that never plug the ear canal, plus IPX7 water resistance and 360-degree panoramic audio.
• Butyoef's biggest trade-off: it's a pair of earbuds — no boom mic, no rotating ear hook, and no published talk-time figure beyond a 300 mAh charging case.
• Atheewon's biggest strength: a purpose-built communication tool — ENC noise-cancelling microphone, 18 hours of talk time per charge, 120 hours total with the case, and Bluetooth 5.4.
• Atheewon's biggest trade-off: it's a single-ear headset with a flip-up mic arm, so it's built for calls and driving rather than immersive stereo listening.
• Buy Butyoef if you want stereo music, situational awareness and a barely-there fit for both ears.
• Buy Atheewon if your day revolves around phone calls, dispatch, meetings and long talk sessions.
The Butyoef set is built around one idea: keep your ears open. Instead of sealing a tip into your ear canal, it hangs on a silicone ear hanger and delivers sound by air conduction. That means no plugged-up feeling, no pressure on the eardrum, and no soreness after a long session. The manufacturer frames this as a "healthier way of listening," and from a design standpoint that's fair — nothing is jammed into the ear, and the skin-friendly silicone reduces friction against the ear contour. For anyone who has ever taken earbuds out after two hours because their ears ached, that's the whole pitch.
Audio is handled by a dynamic driver with 32-ohm impedance and a 20 Hz to 20,000 Hz frequency range, with 50 ms of latency and Bluetooth 5.3 that reaches about 33 feet. Butyoef calls its spatial processing "ACS panoramic audio," simulating a 360-degree stereo field, and pairs it with DirectPitch directional sound-field technology meant to keep sound aimed at you rather than leaking outward. In practice, that's the combination that makes open-ear designs usable in public — you hear your music, the person next to you mostly doesn't. Call quality leans on AI noise cancellation using bi-directional acoustic beams to lock onto your voice and filter background noise. There's also an LED display for status, touch controls, adaptive noise cancellation, and a 300 mAh charging case with three power levels. IPX7 is the headline durability spec: sweat and rain are not a problem.
Atheewon Headset: Who It's For
The Atheewon S72 is a different animal entirely. This is a single-ear Bluetooth headset — the classic trucker/driver/business form factor — with rotating ear hooks, a flip-up microphone, and three sizes of ear tips so you can switch it between left and right ears and spread pressure evenly. The mic is the point: ENC noise reduction filters surrounding noise so your voice comes through clearly in a meeting, on a conference call, or from the cab of a truck. For people who spend their working hours talking, that's the feature that matters most.
Battery is the other headline. Atheewon rates it at up to 18 hours of talk time on a single charge and up to 120 hours total with the charging case, with a 1.5-hour USB-C recharge from empty. The case has an LED display showing remaining charge. Bluetooth 5.4 is the newer standard here, and Atheewon emphasizes faster, more stable connections with lower power draw than the previous generation, plus auto power-on and pairing when you lift the headset out of the box. Audio comes from a 14.2mm dynamic driver — a large driver for a headset this size — tuned for clear, detailed sound rather than the wide spatial field the Butyoef aims for. Controls are physical push buttons for answering, hanging up, volume and playback, which is genuinely easier than touch when you're driving or wearing gloves. It's rated IPX7 as well, so sweat, rain and splashes are covered, and it works with iOS, Android and Windows.
Who should buy it: drivers, truckers, delivery and field workers, and anyone whose phone is basically a work tool. The flip-up mic, rotating hook and multi-device compatibility make it a practical daily driver. Who should skip it: if you want music in both ears with a wide stereo image, or if you dislike having a mic arm near your face, this headset will feel like the wrong shape. It's also mono — one ear only — which is a feature for awareness but a limitation for immersive listening.
Side-by-Side: Which Should You Choose?
• Best for stereo music and immersive sound → Butyoef Open Ear Headphones. 360-degree panoramic processing and a 20 Hz–20 kHz dynamic driver, in both ears.
• Best for talk-time endurance → Atheewon Headset. Up to 18 hours per charge and up to 120 hours with the case, versus a 300 mAh case on the Butyoef with no comparable talk-time figure published.
• Best for a barely-there fit during long sessions → Butyoef Open Ear Headphones. Silicone ear hangers, no ear-canal plugging, no eardrum pressure.
• Best for driving and hands-free use → Atheewon Headset. Rotating hook, flip-up mic, physical buttons and single-ear awareness.
• Best for newer Bluetooth → Atheewon Headset. Bluetooth 5.4 versus 5.3 on the Butyoef.
• Best for water and sweat resistance → a tie. Both are rated IPX7.
• Best for touch controls and a status display → Butyoef Open Ear Headphones. Touch control plus an LED display on the charging case.
• Best for left/right flexibility → Atheewon Headset. Rotating hooks let you wear it on either ear, with three tip sizes included.
If I had to pick one, I'd take the Atheewon Headset for a work-focused buyer. The combination of a boom ENC microphone, 18 hours of talk time, a 120-hour case, Bluetooth 5.4 and push-button controls is exactly what someone who lives on calls actually needs, and the IPX7 rating means rain and sweat aren't a concern. That said, if your priority is music and staying aware of your surroundings, the Butyoef Open Ear Headphones are the better fit — the open-ear design, silicone hangers and 360-degree audio simply aren't what the Atheewon is built to do. In my opinion, these two barely compete; they solve different problems. Match the product to your day, and check the current price on Amazon before you decide.
are ipx7 earbuds waterproof
IPX7 means the device is rated to withstand immersion in water at a specified depth for a limited time, so yes — both the Butyoef Open Ear Headphones and the Atheewon Headset carry an IPX7 rating, which covers sweat, rain and accidental splashes. It is a water-resistance rating, not a claim of unlimited underwater use.
can you shower with ipx7 earbuds
IPX7-rated products are built to handle water exposure, so a shower is well within what the rating is designed for, and both of these models carry it. That said, steam, soap and shampoo are harsher than plain water, and neither brand specifically documents shower use — so I'd treat IPX7 as protection against sweat, rain and splashes rather than an invitation to wear them under a running shower every day.
For calls, the Atheewon Headset is the more purpose-built option: it has an ENC noise-cancelling boom microphone, up to 18 hours of talk time per charge and physical call buttons. The Butyoef relies on AI bi-directional noise cancellation built into an open-ear earbud with no boom mic, which is fine for meetings but less focused on voice pickup.
Open-ear designs sit outside the ear canal, so leakage is a real consideration — but the Butyoef uses DirectPitch directional sound-field technology specifically to keep audio aimed at the wearer and reduce how much escapes. How much you notice depends on volume and how quiet your surroundings are, so keep levels reasonable in shared spaces.
