How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a phone-free, open-ear sports headphone that keeps your ears completely open and lets you carry music on board, choose Potewek Bone Conduction Headphones; if you need maximum battery life with zero electronics at your ear, choose BUSMOV Air Tube Headphones. These two solve very different problems, so the right pick comes down to how and where you actually listen.
• Potewek Bone Conduction Headphones — biggest strength: a hybrid bone-plus-air conduction design paired with a built-in 32GB MP3 player, so you can leave your phone behind entirely.
• Potewek Bone Conduction Headphones — biggest trade-off: battery life is around 10 hours, roughly a third of what the BUSMOV offers, and it charges slower at about 3 hours.
• BUSMOV Air Tube Headphones — biggest strength: a 25-hour battery that charges in just 2 hours, with all the electronics moved away from your head into a behind-neck collar.
• BUSMOV Air Tube Headphones — biggest trade-off: it seals your ear canals with silicone tips, so you lose the open-ear awareness the Potewek is built around.
• Who each pick is for: runners, cyclists and outdoor athletes who want to hear traffic should lean Potewek; commuters, travelers, remote workers and anyone prioritizing long runtime and EMF-free listening should lean BUSMOV.
The Potewek is built around one idea: keep your ears open. The open-ear bone conduction design sits outside the canal rather than inside it, which reduces ear pressure and keeps you aware of your surroundings. If you run on roads, ride a bike near traffic, or walk busy streets, that awareness is the whole point. You hear your music and the world at the same time. The frame is titanium and liquid silicone, which is a sensible combination for a flexible neckband that has to survive sweat and movement, and at roughly 25g it stays light enough to forget you're wearing it.
The standout feature here is the built-in 32GB MP3 player. That's a genuinely different proposition from most Bluetooth headphones. You can load songs directly onto the headphones and listen offline without carrying a phone at all — ideal for a gym session, a trail run, or any situation where you'd rather not risk your phone. The hybrid audio technology blends bone conduction with air conduction, which the spec sheet frames as a way to get clearer sound than bone conduction alone while keeping that pressure-free feel. Bluetooth 6.0 handles everyday wireless use with a 10-meter range, and adaptive noise cancellation is on board for calls.
The waterproofing is the other headline. IP68 means it's rated against sweat, rain and daily water exposure, which is a meaningful step up for anyone who trains hard or gets caught in weather. The controls and fit are aimed squarely at active use, and there's a 1-year warranty.
BUSMOV Air Tube Headphones: Who It's For
The BUSMOV takes the opposite approach. Instead of opening your ears, it seals them — and instead of putting electronics next to your head, it moves everything away. The air tube architecture places the Bluetooth chip, battery and antenna in the behind-neck collar, with sound traveling up hollow air tubes by air vibration. According to the spec sheet, that means no electricity near your head, and the brand describes the earbud position as measuring 0 V/m. It's the core of the pitch: EMF-free listening, which is why the product is positioned for pregnancy, kids and health-conscious buyers.
Battery is where it wins outright. Twenty-five hours of continuous music, calls or podcasts on a 2-hour charge is a big gap over the Potewek's 10 hours — the spec sheet frames it as three-plus workdays or a coast-to-coast flight without a charger. There's a low-battery alert with 30 minutes of warning and an LED screen showing remaining power, which is a nice practical touch for travel days. Bluetooth 5.3 adds dual-device multipoint, so you can switch between a laptop and a phone and take a call while a video plays on your computer. Range is listed at 15 meters, further than the Potewek's 10.
Audio comes from dual 10mm dynamic drivers located in the collar rather than your ears, and the ENC microphone uses AI to separate your voice from wind, traffic and background noise for calls. The in-ear fit uses three sizes of hypoallergenic silicone tips and blocks about 18dB of ambient sound passively — no ANC draining the battery. That's great on a plane or in an office, but it's the exact opposite of the Potewek's hear-your-surroundings design.
Who should buy it: commuters, frequent flyers, remote workers, parents buying for kids, and anyone who specifically wants to minimize EMF exposure. Who should skip it: if you need to hear traffic while you run or ride, the passive seal works against you, and there's no built-in MP3 storage here — this is a Bluetooth-only headphone with a 2-year warranty.
• Best for battery life → BUSMOV Air Tube Headphones. 25 hours versus roughly 10, plus a much faster 2-hour charge.
• Best for outdoor safety and awareness → Potewek Bone Conduction Headphones. The open-ear design keeps you tuned into traffic and surroundings.
• Best for phone-free listening → Potewek Bone Conduction Headphones. The 32GB on-board MP3 player means no phone required.
• Best for travel and long workdays → BUSMOV Air Tube Headphones. The runtime, multipoint switching and low-battery alert are built for exactly this.
• Best for water and sweat resistance → Potewek Bone Conduction Headphones. IP68 is the stronger rating for rain, sweat and water exposure.
• Best for blocking out noise → BUSMOV Air Tube Headphones. The sealed in-ear fit passively cuts around 18dB of ambient sound.
• Best for call clarity in noisy places → BUSMOV Air Tube Headphones. The ENC microphone is specifically designed to isolate your voice from background noise.
• Best if EMF exposure is your main concern → BUSMOV Air Tube Headphones. The air tube design keeps the electronics in the collar, away from your head.
• Best for comfort over long sessions → Potewek Bone Conduction Headphones. At about 25g with no ear-canal pressure, the open design is easier on the ears for hours at a time.
• Best for warranty coverage → BUSMOV Air Tube Headphones. Two years versus one.
If I had to pick one for myself, I'd take the BUSMOV Air Tube Headphones. In my opinion, the 25-hour battery, the 2-hour charge, the multipoint switching and the sealed fit make it the more versatile everyday headphone — it handles commutes, flights, work calls and noisy offices without drama, and the EMF-free design is a real point of difference if that matters to you. I'd only steer myself to the Potewek Bone Conduction Headphones if my priority were outdoor training safety or phone-free music, because that open-ear awareness and the 32GB MP3 player are things the BUSMOV simply doesn't do. Both are solid; they just answer different questions.
The BUSMOV Air Tube Headphones, clearly. The spec sheet lists 25 hours of playtime on a 2-hour charge, while the Potewek Bone Conduction Headphones are rated around 10 hours with a roughly 3-hour charge time.
Per the product's own specifications, all electronics — the Bluetooth chip, battery and antenna — sit in the behind-neck collar, and sound travels through hollow air tubes. The brand describes the earbud position as measuring 0 V/m and says lab reports are available on request. That's the manufacturer's claim, not an independent test I ran.
Yes. That's their standout feature. The built-in 32GB MP3 player lets you store songs on the headphones and listen offline with no phone at all, which is handy for workouts and outdoor sessions.
In my opinion the Potewek Bone Conduction Headphones, because the open-ear design keeps your ears clear so you can hear traffic and your surroundings. The BUSMOV's sealed in-ear fit blocks around 18dB of ambient noise, which is great for focus but less ideal on a busy road.
