How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a pair of everyday true-wireless earbuds that stay put through sweaty workouts and long listening sessions, choose PocBuds Headphones; if you need a headset that keeps playing music while your head is actually underwater, choose Pmjebe Bone Conduction Swimming. These two look like competitors on a search results page, but they solve completely different problems — one is a Bluetooth earbud built for land, the other is a bone conduction headset built around the pool. Below I break down what each design actually delivers, where the trade-offs sit, and which one fits your routine.
• PocBuds Headphones — biggest strength: a conventional Bluetooth 5.3 earbud with 13mm dynamic drivers, ear hooks, a charging case that stretches total playtime to 80 hours, and IPX7 water resistance for sweat and rain.
• PocBuds Headphones — biggest trade-off: it's a Bluetooth-only design. Bluetooth doesn't travel through water, so it's a gym, running and commuting product, not a swimming product.
• Pmjebe Bone Conduction Swimming — biggest strength: a bone conduction headset with IPX8 depth waterproofing and a built-in 8GB MP3 player, so music keeps playing when the Bluetooth signal can't reach you underwater.
• Pmjebe Bone Conduction Swimming — biggest trade-off: underwater it's MP3-only, and bone conduction sound quality depends heavily on how quiet your surroundings are — it's not a hi-fi listening device.
• Who each is for: PocBuds for anyone who wants stereo earbuds with calls, bass and a long battery for land-based training; Pmjebe for lap swimmers, divers and watersport athletes who want music without covering their ears.
PocBuds Headphones are, at their core, a standard pair of true-wireless earbuds done with a sports slant. The 13mm double-layer diaphragm drivers are the headline audio spec, and the frequency range runs a full 20Hz–20,000Hz with 32 ohm impedance — a normal, easy-to-drive configuration. In my reading of that spec sheet, this is a bass-forward tuning aimed at pop, hip-hop and workout playlists rather than critical listening. The built-in microphones isolate your voice for calls, which is the part most cheap earbuds get wrong.
Buy PocBuds if you want earbuds for the gym, running, cycling, TV, laptop or phone use — and you care about bass, call clarity and not babysitting a charger. Skip PocBuds if swimming is your main sport. IPX7 handles splashes, not submersion, and Bluetooth can't transmit through water regardless of rating.
Pmjebe Bone Conduction Swimming: Who It's For
Pmjebe Bone Conduction Swimming is a different animal entirely, and the name tells you why. It transmits audio through the cheekbones to the cochlea using a 13.8mm bone conduction vibrator, which means nothing sits inside or over your ear canal. That open design has a real practical benefit in water: you keep your ears clear, you can wear a swim cap and goggles at the same time, and you stay aware of your surroundings. For anyone who hates the plugged-up feeling of regular earbuds, that's the whole point.
The critical design decision here is the built-in MP3 player. Pmjebe states plainly that Bluetooth signal is isolated in water, so underwater the headset plays from its internal memory only. That's not a limitation they're hiding — it's the reason the product exists. There's 8GB of storage, which they describe as room for around 2,000 songs, and it accepts MP3, WAV, FLAC and WMA files, including lossless formats. You load music by connecting to a PC or Mac and dragging and dropping files. Onboard there are three large tactile buttons designed to be usable mid-stroke, plus a shuffle mode so you can refresh your playlist without stopping. Battery life is listed at about 8 hours, and the whole unit weighs roughly 50 grams.
The waterproofing is the other headline: IPX8, which is a depth rating rather than the splash rating you see on gym earbuds. Pmjebe positions it for swimming, diving, surfing, skiing and cycling. One honest caveat from the spec sheet itself: if your surroundings are noisy, the open design works against you, and they suggest earplugs to improve the sound. Bone conduction is also inherently a different listening experience than a sealed in-ear bud — you're trading bass depth and isolation for awareness and water resistance.
Side-by-Side: Which Should You Choose?
• Best for swimming and diving → Pmjebe Bone Conduction Swimming, thanks to IPX8 depth waterproofing and MP3 playback that works where Bluetooth can't.
• Best for gym, running and cycling → PocBuds Headphones, with ear hooks, IPX7 sweat resistance and a stable Bluetooth 5.3 connection.
• Best for battery life → PocBuds Headphones at roughly 80 hours total with the charging case, versus about 8 hours on the Pmjebe.
• Best for music storage without a phone → Pmjebe, which holds 8GB of drag-and-drop audio and supports FLAC, WAV, MP3 and WMA.
• Best for calls and voice quality → PocBuds, which has built-in microphones with voice isolation — Pmjebe has no call-focused features listed.
• Best for situational awareness → Pmjebe's open bone conduction design, which leaves your ears uncovered so you hear what's around you.
• Best for bass and stereo immersion → PocBuds, with 13mm dynamic drivers and a full 20Hz–20,000Hz range in sealed in-ear mode.
• Best for wearing a swim cap and goggles → Pmjebe, explicitly designed to be worn alongside both.
In my opinion, most people searching these two names actually want PocBuds Headphones. If your "sports" means the gym, a run or a bike ride, the PocBuds give you more of what you'll use every day: real bass, call microphones, stereo or mono mode, and a case that keeps you going for the better part of a week. I'd pick Pmjebe Bone Conduction Swimming only if water is genuinely the point — lap swimming, diving, surfing. In that case Bluetooth is a dead end no matter how good the earbuds are, and the built-in 8GB MP3 player is the feature that makes the whole thing work. Buy for your primary activity, not for the spec sheet that sounds more impressive.

how to wear bone conduction headphones
The Pmjebe unit hangs close to the pinna with the vibrators resting against your cheekbones, and it's designed to sit alongside a swim cap and goggles. It weighs about 50 grams, so it stays light through long sessions.

Load music onto the built-in 8GB memory by dragging and dropping MP3, WAV, FLAC or WMA files from a PC or Mac, then use the three tactile buttons and shuffle mode to control playback. Remember Bluetooth only works out of the water.
how to bone conduction headphones compare to regular earbuds for swimming
Regular earbuds like the PocBuds rely on Bluetooth, which doesn't transmit through water, and their IPX7 rating covers splashes rather than depth. The Pmjebe's IPX8 rating plus onboard MP3 storage is what makes it suitable for actual swimming.
