If you want one set of headphones that survives pool laps, downpours and hour after hour of gym work while leaving your ears open to traffic, choose DEMICEA Open Ear Sport; if you need a proper over-ear gaming headset that plugs into a PS5, Xbox, PC or Switch and lets you hear footsteps before you see them, choose RK ROYAL KLUDGE HG103.
• DEMICEA Open Ear Sport – biggest strength: an IP68-sealed bone conduction hook design with 32GB of built-in storage, so you can swim or run without a phone anywhere near you.
• DEMICEA Open Ear Sport – biggest trade-off: bone conduction sound leaks almost nothing but also never seals your ear canal, so deep bass and total noise isolation simply aren't part of the deal, and there's no noise control at all.
• RK ROYAL KLUDGE HG103 – biggest strength: three connection modes (2.4GHz dongle, Bluetooth 5.3 and 3.5mm wired), 50mm drivers and 7.1 virtual surround sound built for competitive shooters.
• RK ROYAL KLUDGE HG103 – biggest trade-off: it's a 299g over-ear headset that wants a desk, a console or a long session — not a swimming pool or a sweaty 10K.
• Bottom line: DEMICEA for swimmers, runners and anyone training phone-free; RK ROYAL KLUDGE for console and PC gamers who need positional audio and a boom mic.
The DEMICEA Open Ear Sport is built around one idea: keep your ears uncovered and keep going. It's an open-ear bone conduction hook headphone, so nothing sits inside your ear canal. Instead, a 16mm bone conduction driver sends sound through the cheekbone area, and SoundBeam directional field technology keeps that audio aimed at you rather than broadcasting it to the treadmill next to yours. The frame is a 0.7mm flexible memory titanium alloy with a skin-friendly silicone rear bridge, and the whole thing weighs 26g — light enough that the spec sheet's claim of "all-day comfort without hindering sunglasses wear" is at least structurally plausible rather than marketing noise.
Buy it if you swim, run outdoors, lift, or cycle and you want situational awareness plus phone-free music. Skip it if you want to disappear into a wall of bass, need active noise cancelling, or plan to use it for competitive gaming — Bluetooth 5.3 with AAC/SBC is fine for music and calls, but bone conduction and virtual surround sound are two different sports.
RK ROYAL KLUDGE HG103: Who It's For
The RK ROYAL KLUDGE HG103 is the opposite kind of product, and it doesn't pretend otherwise. It's an over-ear gaming headset with 50mm dynamic drivers, 32 ohm impedance, 120dB sensitivity and 7.1 virtual surround sound — a spec stack aimed squarely at hearing a footstep behind a wall in an FPS before the other player rounds the corner. The detachable boom mic uses dual-mic ENC (environmental noise cancellation) to filter out keyboard clatter and room hum, which is the difference between your squad hearing your callouts and hearing your mechanical keyboard.
The real story here is connectivity. You get a 2.4GHz USB-A + USB-C dongle for low-latency, audio-visual-synced gaming, Bluetooth 5.3 for phone calls and music away from the desk, and a 1.2m 3.5mm cable for wired use. That last one matters because the sheet is explicit: Xbox supports 3.5mm wired mode only, while Bluetooth is intended for phones, tablets and PCs — so console owners should plan on the dongle or the cable, not Bluetooth. Battery is a claimed 40 hours on a 2-hour charge in wireless mode, and the RGB lighting can be switched off with a double-tap of the power button if you want to stretch that further or just prefer a quieter look.
At 299g with an aluminium frame and over-ear cups, this is a stay-put headset for long sessions. Buy it if you game on PS5, PS4, PC or Switch and want one headset that covers 2.4GHz, wired and Bluetooth. Skip it if you need something for swimming, running or anything where 299g on your head is a non-starter.
Side-by-Side: Which Should You Choose?
• Best for phone-free workouts → DEMICEA Open Ear Sport. 32GB of built-in storage is roughly 4,000 songs with no phone required.
• Best for outdoor awareness → DEMICEA Open Ear Sport. Open-ear bone conduction leaves your canal unobstructed, so traffic and training partners stay audible.
• Best for battery life → RK ROYAL KLUDGE HG103. 40 hours wireless versus 8 hours — a five-fold difference on the sheets.
• Best for competitive gaming → RK ROYAL KLUDGE HG103. 50mm drivers, 7.1 virtual surround and a 2.4GHz low-latency dongle are purpose-built for it.
• Best for voice chat and streaming → RK ROYAL KLUDGE HG103. A detachable ENC boom mic beats a bone conduction mic array for clarity in noisy rooms.
• Best for all-day wear comfort → DEMICEA Open Ear Sport. 26g on a flexible titanium hook versus 299g of over-ear hardware.
• Best for multi-device flexibility → RK ROYAL KLUDGE HG103. 2.4GHz, Bluetooth 5.3 and 3.5mm wired in one box.
In my opinion, these two aren't really competing — they're two different jobs, and you should buy the one that matches yours. If your training involves water, sweat, weather or leaving your phone behind, I'd take the DEMICEA Open Ear Sport: IP68, 32GB of local storage and a 26g hook frame are a combination almost nothing else in the open-ear category offers. If your priority is winning firefights and talking to your squad on a console or PC, I'd take the RK ROYAL KLUDGE HG103 without hesitation — the 50mm drivers, 7.1 surround, ENC boom mic and triple connectivity are exactly what a gaming headset should be. Buy for the job, not for the spec sheet.
Only the DEMICEA is designed for it. It carries an IP68 rating with a sealed body and nano-hydrophobic coating, while the RK ROYAL KLUDGE HG103 is an over-ear gaming headset with no water rating in its specs.
Yes. Bluetooth 5.3 is intended for phones, tablets and PCs, and the 2.4GHz dongle or 3.5mm cable handles consoles. Just note that Xbox works over the 3.5mm wired connection only.
No — that's its standout feature. With 32GB of built-in storage you can load roughly 4,000 songs over the magnetic cable and listen with no phone and no Bluetooth connection at all.
I can't quote prices here, and both products sit in very different categories, so the honest answer is to check the current price on Amazon using the button on this page and compare them against the job you actually need done.
