• HiBOMASOON's biggest strength: a genuinely waterproof, non-falling in-ear design with a built-in 32GB MP3 player — so you can listen underwater with no phone nearby.
• HiBOMASOON's biggest trade-off: it's a sports-first, in-ear hook design with modest battery life (about 8 hours claimed playback) and no active noise cancellation.
• FiiO JN3's biggest strength: hybrid ANC up to 35dB, LDAC Hi-Res audio and a huge 115-hour battery rating in a comfortable over-ear frame.
• FiiO JN3's biggest trade-off: it's an over-ear headphone built for dry, everyday listening — it is not a swimming device and has no on-board music storage.
• Pick HiBOMASOON if you swim, dive, spa, run or cycle and want music that stays put without a phone.
• Pick FiiO JN3 if you want immersive, noise-cancelled listening for commuting, studying, movies, gaming and long sessions.
This is a niche product that solves one problem extremely well: keeping music on your head while you're in the water. The headline feature is waterproofing coupled with a built-in MP3 player and 32GB of memory. That combination matters because Bluetooth simply doesn't travel through water reliably — so instead of streaming from a phone in a locker, you load songs into the headphones themselves and listen directly. The spec sheet says the 32GB can hold roughly 1,000 songs in one place and about 5,000 in another; either way, it's far more music than any single workout needs.
The fit is clearly engineered for movement. HiBOMASOON uses an ergonomic in-ear shape with silicone ear hooks and an adaptive buckling band that sits on the back of the head. The stated goal is that they never fall out — which is exactly the failure mode that ruins cheap earbuds during laps, hill sprints or a session in the gym. The enclosure is liquid silicone, which should feel soft against skin and resist chlorine and sweat better than hard plastic. Bone conduction drivers are listed, which is an interesting choice: it suggests the sound is delivered without sealing the ear canal, a design that tends to stay comfortable over long wear and lets you stay aware of your surroundings.
On the practical side, you get two listening modes — Bluetooth 5.3 and MP3 — with multipoint connection in Bluetooth mode, so it can pair with more than one device. Controls are physical buttons rather than touch, which I actually prefer when my hands are wet or I'm mid-stride. Battery is a 230mAh cell with roughly 8 hours of playback, more than 100 hours of standby and a 2-hour charge time. There's a 1-year manufacturer warranty, and it comes in red or blue.
Who should buy it: swimmers, divers, spa and bath users, runners, cyclists and gym-goers who want phone-free music that won't budge. Who should skip it: anyone who wants noise cancellation, audiophile-grade wireless codecs, or a single pair of headphones to cover both the pool and the office. This is a specialist tool, not a do-everything headphone.
The FiiO JN3 sits at the opposite end of the spectrum. It's an over-ear wireless headphone with a custom 40mm dynamic driver, tuned for punchy bass, clear vocals and detailed highs. If your listening happens at a desk, on a train, on a plane or on the couch, that driver size and tuning are aimed squarely at you. It supports LDAC, which transmits significantly more data than standard Bluetooth codecs — the practical benefit being more preserved detail from high-resolution sources, assuming your phone or player supports LDAC too.
The second pillar is hybrid active noise cancellation rated up to 35dB. That's the feature that turns a noisy commute or a shared office into a usable listening space, and it's the single biggest functional gap between these two products. There's also spatial audio with head tracking, which widens the perceived soundstage for movies and games — a nice-to-have that most music-first listeners will leave off, but genuinely fun with the right content.
Battery is where the JN3 runs away with it: up to 115 hours of playback in standard mode and up to 65 hours with ANC on. Even the ANC figure is several times what the HiBOMASOON offers, and it means charging becomes a weekly or even monthly chore instead of a daily one. The design is lightweight and foldable with soft ear cushions, and it includes multipoint connectivity so you can stay connected to a laptop and a phone at once. There's also a 3.5mm jack, which is increasingly rare and useful for wired listening on a plane or with older gear. Controls are touch-based, and it comes in Apricot White with a 1-year warranty.
Who should buy it: commuters, students, remote workers, travellers, gamers and movie watchers who want one comfortable headphone for long daily sessions. Who should skip it: swimmers and anyone who needs waterproofing or built-in storage — the JN3 has no on-board music memory and is not designed to get wet.
• Best for swimming and water sports → HiBOMASOON Swimming Headphone Underwater. Its waterproof build and non-falling hook design exist specifically for this.
• Best for phone-free listening → HiBOMASOON. The built-in MP3 player and 32GB of memory mean no paired device is required.
• Best for noise cancellation → FiiO JN3. Hybrid ANC up to 35dB versus sound isolation only on the HiBOMASOON.
• Best for battery life → FiiO JN3. Up to 115 hours standard, 65 hours with ANC, against roughly 8 hours of playback on the HiBOMASOON.
• Best for audio quality and codecs → FiiO JN3. A 40mm dynamic driver plus LDAC support is a clear step up for critical listening.
• Best for long-session comfort → FiiO JN3. Lightweight, foldable, over-ear cushions suit hours of wear; the HiBOMASOON is built for grip and stability instead.
• Best for movies, gaming and immersion → FiiO JN3. Spatial audio with head tracking is designed for exactly that.
• Best for a wet, high-movement workout → HiBOMASOON. Silicone ear hooks and a back-of-head band hold firm where over-ear cans would slide.
In my opinion, these two shouldn't really be competing for the same buyer — they solve different problems. If you swim, dive or train hard in the water, I'd buy the HiBOMASOON Swimming Headphone Underwater, because the combination of waterproofing, a secure hook-based fit and 32GB of built-in storage is something the JN3 simply cannot do. If your listening happens on dry land — commuting, studying, working, watching films — I'd buy the FiiO JN3 without hesitation: ANC, LDAC and 115 hours of battery make it the far more capable everyday headphone. Buy the HiBOMASOON for the pool, the JN3 for everything else.
No. The JN3 is an over-ear headphone designed for everyday listening with a 3.5mm jack and touch controls. There's no waterproof rating listed, and it has no built-in MP3 storage, so it isn't a swimming device. For water use, the HiBOMASOON is the appropriate pick.
Yes. It has a built-in MP3 player with 32GB of memory, so you can preload your music and listen without pairing anything. It also supports Bluetooth 5.3 mode with multipoint if you do want to connect a device.
The FiiO JN3 by a wide margin: up to 115 hours of playback in standard mode and up to 65 hours with ANC enabled. The HiBOMASOON is rated at about 8 hours of playback, with more than 100 hours of standby and a 2-hour charge time.
For detailed music listening, the FiiO JN3 has the edge on paper — a custom 40mm dynamic driver plus LDAC Hi-Res wireless support and spatial audio. The HiBOMASOON uses bone conduction drivers tuned for sports and water use, where staying put matters more than audiophile resolution.
