• EKSA 2.4GHz — biggest strength: a 2.4GHz USB/Type-C dongle link under 30ms latency, plus Bluetooth 5.4, a 35-hour battery and a 169g frame. That's a lot of flexibility in one headset.
• EKSA 2.4GHz — biggest trade-off: it's a desk-and-couch product. Nothing in its spec sheet suggests water resistance, and the 169g over-ear build is not something you'd want to swim or run in.
• Roujune Swimming Headphones Bone — biggest strength: TÜV-certified IP68 sealing, a 32GB MP3 mode that works without a phone, and a 27g open-ear bone conduction design that survives up to two meters of water for an hour.
• Roujune Swimming Headphones Bone — biggest trade-off: bone conduction sound is thinner than a 40mm dynamic driver, and Bluetooth simply doesn't work underwater — you must switch to MP3 mode before you get in.
• Pick EKSA 2.4GHz if you care most about low-latency audio, a boom mic for teammates, and long battery life at a PC or console.
• Pick Roujune Swimming Headphones Bone if your priority is laps in a pool, open-ear awareness, and music that plays with no phone nearby.
The EKSA G19BT is built around one idea: get audio from your device to your ears as fast as possible. The 2.4GHz wireless path is rated under 30ms latency, which is the whole point of a dongle-based connection — footsteps, gunfire and on-screen action stay lined up instead of trailing behind. There's also Bluetooth 5.4 on board, plus a Type-C to USB adapter and a Type-C to 3.5mm audio cable in the box, so the same headset can serve a PS5, a PS4, a PC, a Switch, a Mac, or a phone. In my opinion that's the real selling point: one headset that covers the whole desk instead of three.
The audio side is a tuned 40mm dynamic driver running 20Hz–20,000Hz at 80 ohm impedance, with a one-tap switch between a game mode (positioning and low latency) and a music mode (fuller, richer sound). The slot-in noise-cancelling boom mic is the piece gamers will actually notice — it's flexible, it cuts background noise, and it folds into the earcup when you're done so the headset doesn't look like a call-center rig in public. Battery is rated up to 35 hours, a full charge takes 2.5 hours over USB-C, and fast charge gives you hours of use in minutes.
Who should skip it? Anyone shopping for swimming, running in the rain, or heavy sweat. There's no IP rating here, and the open-ear, on-land use case belongs to the other product. If your headset never leaves the desk, this is the more capable tool.
Roujune Swimming Headphones Bone: Who It's For
The Roujune X20 Pro is a specialist, and it's honest about it. The core spec is TÜV-certified IP68 waterproofing with seals designed for underwater use, which is a different engineering problem than "splash resistant." It's rated to be submerged up to two meters for one hour. The open-ear, bone conduction design sends sound through the cheekbones rather than the eardrums, so your ear canals stay open — that's the safety argument for swimming, running and cycling, because you still hear what's around you. At 27g with soft liquid silicone and a flexible titanium memory neckband, it's designed to sit still under a swim cap and goggles.
The feature that actually makes it work in a pool is the 32GB of built-in storage and MP3 mode. Bluetooth cannot travel through water, and Roujune says so plainly: switch to MP3 mode before you swim. You can hold roughly 8,000 songs on board, and a double-press of the power button toggles Bluetooth and MP3 modes, with a triple-press switching between sequential and shuffle playback. Supported file formats are MP3, WMA, FLAC, APE and WAV — worth knowing before you load it up. When you're out of the water, Bluetooth 5.4 handles a stable connection up to 10 meters, supports dual-device pairing so you can hop between a laptop and a phone, and is rated for up to 6 hours of playback. It's compatible with iOS and Android, and there's a 2-year after-sales service.
The trade-offs are real. Bone conduction doesn't deliver the bass punch or isolation of a 40mm driver, and that's inherent to the technology, not a defect. Battery is 6 hours versus EKSA's 35. And the underwater experience is MP3-only — if you forget to switch modes, you'll get silence, not a warning. The box includes a magnetic charging cable, an adjustment strap, waterproof earplugs and a waterproof bag, which tells you the intended use case clearly.
Who should buy it? Swimmers first, then runners and cyclists who want awareness. Who should skip it? Anyone who wants rich bass, a boom mic, or a headset for competitive gaming voice chat.
• Best for low-latency gaming → EKSA 2.4GHz. The under-30ms 2.4GHz link and dedicated game mode are exactly what competitive play needs.
• Best for voice chat and team callouts → EKSA 2.4GHz. The slot-in noise-cancelling boom mic has no equivalent on the Roujune.
• Best for battery life → EKSA 2.4GHz. Up to 35 hours versus up to 6 hours.
• Best for swimming → Roujune Swimming Headphones Bone. TÜV-certified IP68, submersible to two meters for an hour, and MP3 playback with no phone required.
• Best for running and cycling awareness → Roujune Swimming Headphones Bone. Open-ear bone conduction at 27g keeps you tuned into traffic and surroundings.
• Best for device versatility at a desk → EKSA 2.4GHz. 2.4GHz USB, Type-C wireless, Bluetooth 5.4, plus a 3.5mm cable and a Type-C to USB adapter in the box.
• Best for phone-free listening → Roujune Swimming Headphones Bone. 32GB of onboard storage holds up to 8,000 songs.
• Best for long-session comfort → it depends on the setting. EKSA's 169g over-ear build with mesh pads is made for hours at a desk; Roujune's 27g open-ear frame is made for movement.
• Best for durability in water → Roujune Swimming Headphones Bone. There's no water rating on the EKSA at all, so keep it dry.
If I had to pick one, I'd buy the EKSA 2.4GHz. For most people most of the time, it covers more ground: low-latency wireless for gaming, Bluetooth 5.4 for everything else, a genuinely useful noise-cancelling boom mic, 35 hours of battery and a 169g frame that won't wear you out. That's a headset you'll use daily. The Roujune is the better product for exactly one thing — being in the water — and it does that job in a way the EKSA simply can't. If you swim laps, buy the Roujune. Otherwise, the EKSA is my recommendation. Check the current price on Amazon before you commit.
FAQ
No. Bluetooth signals don't transmit underwater, which is why Roujune ships 32GB of storage and an MP3 mode. Double-press the power button to switch to MP3 before you get in.
Yes. It supports 2.4GHz USB, Type-C wireless, Bluetooth 5.4 and a 3.5mm cable, and the box includes a Type-C to USB adapter and a Type-C to 3.5mm audio cable. It's listed for PS5, PS4, PC, Switch and Mac.
It depends what you're buying it for. If you want one headset for gaming, calls and music, the EKSA covers more ground for the money. If you swim regularly, the Roujune's IP68 sealing and onboard MP3 storage justify it on their own. Compare current prices on Amazon for both.
