If you want a swimming-capable hybrid headphone with a true MP3 mode and a titanium memory frame, choose VLOP Bone Conduction Headphones; if you need the longest playtime per charge, adaptive noise cancellation and a lighter 25g neckband for running and cycling, choose Potewek Bone Conduction Headphones.
• VLOP – biggest strength: A genuine hybrid bone + air conduction driver set paired with IP68 sealing rated for full immersion, so it works both as an everyday open-ear headphone and as an underwater MP3 player.
• VLOP – biggest trade-off: Bluetooth does not work underwater, so swimming forces you into MP3 mode, which drains the battery faster than wireless playback.
• Potewek – biggest strength: Up to 10 hours of average battery life with a 3-hour charge, plus adaptive noise cancellation, in a lighter 25g titanium-and-silicone frame.
• Potewek – biggest trade-off: The IP68 rating covers sweat, rain and daily water exposure, but the sheet does not describe immersion or underwater playback, so I would not treat it as a swim-first headphone.
• Pick VLOP if you split your training between the pool and the road and want one device for both.
• Pick Potewek if your workouts are land-based, your sessions run long, and you want the lighter, more comfortable wear.
VLOP's whole pitch is versatility. It runs a hybrid dual-driver setup that combines bone conduction clarity with air conduction bass, which is the design that lets an open-ear headphone deliver something closer to the low-end thump of a conventional pair. According to the data sheet, the driver is listed as a bone conduction driver, but the marketing copy describes the hybrid pairing as the core of the sound. Either way, this is not a single-trick product.
The headline feature is the waterproofing. The triple-sealed structure is rated to resist sweat, rain and full water immersion up to 2 meters for 2 hours. That is a different class of protection than "splash-resistant." It supports MP3 playback underwater, and the sheet is refreshingly honest about the catch: Bluetooth does not operate underwater, so for swimming you triple-click the MFB button to jump into MP3 mode, which plays files stored in the built-in 32GB memory. You load those files by connecting the headphones to a PC with the included charging cable. Expect higher power draw in MP3 mode than in Bluetooth mode — that is stated as normal behavior, not a fault.
Storage is generous: up to 8000 songs, which is enough to never repeat a track across a full season of swims. On land you get Bluetooth 6.0 with a low-latency connection, up to 8 hours of playtime, magnetic charging, and a 26g open-ear titanium memory frame with soft silicone coating that stays put under swim caps, goggles, sunglasses or a helmet. There is a 1-year warranty.
Buy it if you want one headphone that handles pool laps, open-water swims, triathlon training, cycling and hiking without you babysitting it. Skip it if you mostly train on land, want maximum battery life, or expect to control playback underwater with your phone in Bluetooth range — that simply is not how the swim mode works.
Potewek plays a narrower but very well-defined game: all-day comfort and battery endurance for land sports. The frame is titanium with liquid silicone, weighs roughly 25g, and uses a flexible neckband that sits around the back of your head rather than over your ears. That open-ear bone conduction layout is designed to reduce ear pressure and keep you aware of traffic, other runners and whatever is happening around you — the main reason people move to this category in the first place.
The battery numbers are the standout. The sheet lists a 3-hour charge time and an average life of 10 hours, which is the longest figure between these two products. For a long ride, a double session at the gym or a full day of commuting, that matters more than almost anything else. Bluetooth 6.0 with a 10-meter range covers normal use with a phone or watch, and there is no headphone jack, so this is a wireless-only design.
It also carries a 32GB built-in MP3 player, so you can leave the phone at home for offline listening on a trail run or a gym session. The hybrid driver combines bone conduction and air conduction for clearer sound than bone conduction alone typically manages. Potewek adds adaptive noise cancellation, which VLOP does not list at all, and the IP68 rating handles sweat, rain and daily water exposure. The enclosure materials are titanium and liquid silicone, the listed age range is adult, and there is a 1-year warranty.
Buy it if you run, cycle, lift or commute and want the lightest possible open-ear fit with the longest runtime and some noise management. Skip it if you swim laps and want underwater playback — the sheet describes protection against daily water exposure, not immersion playback, so a pool is not the use case this one is built around.
Side-by-Side: Which Should You Choose?
• Best for battery life → Potewek Bone Conduction Headphones (up to 10 hours average vs. 8 hours on VLOP).
• Best for phone-free listening on land → Potewek Bone Conduction Headphones (32GB MP3 player without needing a PC round-trip in the middle of a session).
• Best for loading your own music library → VLOP Bone Conduction Headphones (up to 8000 songs transferred from a PC over the included cable).
• Lightest fit → Potewek Bone Conduction Headphones at roughly 25g vs. 26g for VLOP. It is a small gap, but the flexible neckband design is the bigger difference in how it feels.
• Best for helmet-wearers → VLOP Bone Conduction Headphones (the sheet specifically calls out a secure fit under helmets, goggles and swim caps).
• Noise control → Potewek Bone Conduction Headphones (adaptive noise cancellation listed; VLOP lists none).
• Best for mixed pool-and-road athletes → VLOP Bone Conduction Headphones, because it is the only one of the two designed for immersion.
For most people reading this, I would buy the VLOP Bone Conduction Headphones. In my opinion, the immersion-rated IP68 build plus MP3 mode gives you a capability the Potewek simply does not claim, and the 8-hour runtime with Bluetooth 6.0 and a 26g titanium frame covers everyday training just as well. That said, if you never get in the water and long battery life is your priority, the Potewek's 10-hour figure and adaptive noise cancellation make it the smarter pick for pure land sports. Check the current price on Amazon before you decide, since that is the one variable this comparison cannot speak to.
FAQ
how to wear air conduction headphones
how to use air conduction headphones
Power them on, pair over Bluetooth 6.0 with your phone, and play as normal. When you want to go phone-free, switch to MP3 mode and play files from the 32GB built-in memory. On the VLOP, triple-click the MFB button for MP3 mode, and note that Bluetooth does not work underwater, so swimming always means MP3 mode.
how to put on air conduction headphones
Slide the neckband around the back of your head, then settle the transducers against your cheekbones so they sit flat and firm. The Potewek's flexible titanium-and-silicone band is designed to bend slightly for a secure fit; the VLOP uses a titanium memory frame that springs back into shape. Neither should press hard against your ears.
how to pair goodmans air conduction headphones
That is a different brand, so the exact steps will differ, but the general method is the same as here: hold the power or multifunction button until the indicator flashes, open your phone's Bluetooth settings, and select the headphone from the list. Both VLOP and Potewek pair over Bluetooth 6.0, and the Potewek has a listed wireless range of about 10 meters.
