How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want all-day open-ear comfort with dual-device Bluetooth switching, choose NEARITY MemPod Fit 2; if you need a headphone that keeps playing music while you're actually underwater, choose HiBOMASOON Swimming Headphone Underwater.
• NEARITY MemPod Fit 2 — biggest strength: open-ear silicone design at just 9.9g per earbud, with ENC noise-cancelling mics, HiFi4 DSP, Bluetooth 5.3 multipoint and a charging case that stretches total listening to roughly 45 hours.
• NEARITY MemPod Fit 2 — biggest trade-off: it is not built for water. Nothing in the spec sheet claims a waterproof rating, and open-ear bass is explicitly described as weaker than in-ear designs.
• HiBOMASOON Swimming Headphone Underwater — biggest strength: a genuinely swim-ready design with an IPX8 waterproof claim, sealed magnetic charging, a built-in 32GB MP3 player and a bone-conduction driver that leaves your ears open to water and traffic.
• HiBOMASOON Swimming Headphone Underwater — biggest trade-off: it's a specialist tool. The headband-and-hook fit is bulkier than a lifestyle earbud, and getting your music onto it means managing files in MP3 mode rather than just streaming from your phone.
• Who each pick is for: the MemPod Fit 2 is for commuters, office workers, walkers and gym-goers who want to stay aware of their surroundings; the HiBOMASOON is for swimmers, divers and anyone who trains in water.
The MemPod Fit 2 is an open-ear Bluetooth headphone, and everything about it is designed around the idea that you should hear your music and your environment at the same time. Each earbud weighs only 9.9g and uses skin-friendly silicone with ergonomic ear hooks, so the fit sits against the natural contour of your ear rather than plugging the canal. In my opinion, that's the whole point: you can walk a busy street and still hear traffic, or sit in an office and still catch a colleague calling your name. The enclosure material is silicone, the color option is a clean white, and the package includes the headphones, a charging case, a charging cable, a user manual and a quick start guide.
On the audio and call side, the spec sheet is more interesting than the usual open-ear pitch. There are 2 MEMS microphones paired with ENC noise cancelling and HiFi4 DSP, which is aimed squarely at the person on the other end of your call — the goal is that your voice comes through clearly even in a noisy office, a restaurant or a busy street. The drivers are tuned for deep bass and robust volume, but NEARITY is refreshingly honest here: the bass is improved through an enhancement algorithm and still won't match an in-ear headphone. That's a fair trade for open-ear comfort, and worth knowing before you buy.
Buy it if you want a lightweight, all-day open-ear headphone for commuting, desk work, walking, light gym sessions and calls. Skip it if you need something for swimming or heavy sweat in water — there's no water-resistance claim anywhere in this data sheet, and it simply isn't that product.
HiBOMASOON Swimming Headphone Underwater: Who It's For
The HiBOMASOON Swimming Headphone Underwater is built for one job and does it in a very specific way. It carries an IPX8 waterproof claim, charges magnetically (which means no exposed port to leak through), and runs from a built-in 230mAh battery with more than 100 hours of standby and roughly 8 hours of playback per charge. There's also a 32GB internal memory for pre-loaded music — the sheet mentions space for well over 1,000 songs, and elsewhere around 5,000. That's the key detail: underwater, Bluetooth doesn't travel, so the MP3 mode is what actually keeps music playing while you swim.
The driver is listed as bone conduction with a 32-ohm impedance and a 20Hz–20,000Hz frequency range. Bone conduction is the reason this design works in water at all — it sends sound through your cheekbones instead of sealing your ear canal, so your ears stay open and you keep awareness of your surroundings. The fit is described as in-ear with silicone ear hooks plus an adaptive buckling band across the back of the head, which is what keeps it from falling out during laps, dives or turns. The enclosure is liquid silicone, it's available in red or blue (the listed unit is blue), and it supports Bluetooth 5.3 with multipoint for multiple devices, plus a voice-language toggle between Chinese and English.
Switching between Bluetooth and MP3 mode is done with button controls on the headset. That's a small thing that matters: wet fingers on a touch panel are a nightmare, and physical buttons are the right call for a swimming product. Charge time is about 2 hours, which lines up with the MemPod Fit 2's case recharge.
Buy it if you swim, dive, or train in water, or you want music in a spa, bath or pool without your phone nearby. Skip it if you mainly want an everyday headphone for calls and streaming — the bulkier headband fit and the file-management side of MP3 mode make it a worse daily driver than an open-ear bud.
• Best for water and swimming → HiBOMASOON Swimming Headphone Underwater. IPX8 plus magnetic charging plus onboard MP3 playback is the only combination here that survives a pool.
• Best for all-day comfort and light weight → NEARITY MemPod Fit 2. At 9.9g per earbud in soft silicone, it's built to disappear on your ears over long days.
• Best for battery life → NEARITY MemPod Fit 2. Up to 10 hours per charge plus roughly 35 hours from the case, versus about 8 hours of playback on the HiBOMASOON.
• Best for calls and meetings → NEARITY MemPod Fit 2. Two MEMS mics, ENC noise cancelling and HiFi4 DSP are aimed at making your voice clear to the other person.
• Best for listening without a phone nearby → HiBOMASOON Swimming Headphone Underwater. The 32GB of built-in storage means your library lives on the headphone itself.
• Best for staying aware of traffic and surroundings → tie, for different reasons. The MemPod Fit 2 leaves your ears open by design; the HiBOMASOON leaves them open because bone conduction doesn't block the canal.
• Best for switching between a phone and a laptop → NEARITY MemPod Fit 2. Bluetooth 5.3 multipoint handles two devices at once with no re-pairing.
• Best for runners who sweat heavily and want maximum security → HiBOMASOON Swimming Headphone Underwater. The ear hooks plus the back-of-head band are explicitly designed so it never falls out.
• Best for bass and immersive music → NEARITY MemPod Fit 2, with the caveat that NEARITY itself says in-ear headphones still beat it on bass.
• Widest platform compatibility → NEARITY MemPod Fit 2. It's listed as working with iOS, Android, Windows, Mac and Linux.
For most people reading this, I'd buy the NEARITY MemPod Fit 2. It fits more of daily life — commuting, calls, desk work, walking, the gym — and the combination of a 9.9g open-ear fit, ENC calling, multipoint Bluetooth 5.3 and up to 45 hours of combined battery is genuinely useful every single day. The HiBOMASOON is the better product for exactly one thing, and if that one thing is swimming, nothing about the MemPod Fit 2 will substitute for it. So my honest advice: if water is your priority, get the HiBOMASOON. If water isn't part of your routine, the MemPod Fit 2 is the smarter everyday pick.
FAQ
Yes. It has Bluetooth 5.3 with multipoint, so you can pair it with a phone or laptop like any other wireless headphone, and switch to MP3 mode when you don't want to carry a device. It's just bulkier and more specialized than an open-ear bud for all-day wear.
It's tuned for deep bass and robust volume, and NEARITY notes it uses a bass enhancement algorithm — but the manufacturer also states plainly that the bass still won't match an in-ear headphone. If deep, sealed bass is your priority, an open-ear design isn't the right category.
