How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a wired, Xbox-licensed gaming headset built for marathon sessions, choose HyperX CloudX; if you need open-ear, waterproof headphones for swimming, cycling and phone-free listening, choose CXK Bone Conduction Headphones.
These two products barely share a category. One is a wired over-ear gaming headset with a detachable mic. The other is a bone conduction open-ear wearable that can go two meters underwater. Comparing them only makes sense if you're deciding where your money goes — gaming desk or pool lane. So let's go through it properly.
• HyperX CloudX — biggest strength: Official Xbox licensing, a detachable noise-cancelling mic, in-line audio controls, and a durable aluminum frame with memory foam comfort for long sessions.
• HyperX CloudX — biggest trade-off: It's fully wired with a 3-foot braided cable, no wireless option, no noise cancellation, and no water resistance whatsoever.
• CXK Bone Conduction Headphones — biggest strength: IPX8 waterproofing rated for immersion up to 2 meters for 2 hours, plus Bluetooth 6.0 and a built-in MP3 mode with storage for up to 8,000 songs.
• CXK Bone Conduction Headphones — biggest trade-off: Bone conduction audio doesn't seal your ears, so it trades isolation and bass depth for awareness, and Bluetooth doesn't work underwater at all.
• Who each pick is for: HyperX CloudX is for Xbox players who want a mic and reliable wired audio; CXK is for swimmers, cyclists and runners who want music while staying aware of their surroundings.
HyperX CloudX is a gaming headset first and everything else second. It was tested by Microsoft and is officially licensed for Xbox, working with Xbox One and Xbox Series X|S controllers that have a 3.5mm headset jack. That licensing matters in practice: it means plug-and-play on Xbox without dongles, adapters or pairing menus. You plug the 3.5mm jack into the controller and you're in.
The build is the other headline. An aluminum frame gives it stability and durability, and the over-ear memory foam cushions are designed for marathon sessions rather than quick bursts. The detachable noise-cancelling mic is flexible and positionable, and you can pull it off entirely when you just want to listen to music. In-line controls let you adjust volume and mute the mic without digging through console settings. The braided cable is 3 feet long, which suits a controller-mounted setup, and the drivers are 5.3cm dynamic units with a 20Hz–20,000Hz frequency range, 41 ohm impedance and 95dB sensitivity. At 297g it's a substantial headset, and the 2-year warranty backs up the durability claim.
Who should buy it: Xbox players who want a wired, no-fuss headset with a real microphone and comfort that holds up over hours. Who should skip it: anyone who wants wireless freedom, anyone who needs noise cancellation (this headset has none), and definitely anyone who wants to wear headphones in water. If you mostly game on PC or mobile and want Bluetooth, this isn't the tool.
The CXK X17 is a different species entirely. It's an open-ear bone conduction headphone with a wrap-around titanium alloy frame and soft silicone pads, designed so your ear canals stay open. That's the whole point: you hear your music and your surroundings at the same time, which is exactly what you want on a bike or a run. The adjustable headband is meant to fit different head shapes securely.
The standout feature is the IPX8 waterproof rating with a triple-seal design, good for immersion in water up to 2 meters deep for 2 hours. That's swimming-grade, not splash-grade. Here's the catch the specs make clear: Bluetooth can't connect underwater, so you double-click the power button to switch to MP3 mode before you get in. The built-in memory holds up to 8,000 songs, and it only reads WMA, FLAC, WAV and MP3 files — so pick your format before you load it up.
Audio comes from a 12mm CXK PulseCraft bone conduction transducer, with 32 ohm impedance, 20Hz frequency response and 105dB sensitivity. CXK claims up to 3x clarity and depth improvement over earlier designs, and there are up to 2 microphones with AI noise-cancelling algorithms for calls. Battery life is up to 12 hours with magnetic charging that tops up in about 1.5 hours. Bluetooth 6.0 gives you a 33-foot range on land. There's also a companion app with custom EQ modes and an AI music generation feature, if that appeals. Weight is just 1.06 ounces — you'll barely notice it.
Who should buy it: swimmers, rowers, surfers, cyclists and gym-goers who want audio without blocking their ears. Who should skip it: anyone who wants deep bass isolation, anyone who needs a boom mic for competitive gaming chat, and anyone who wants a wired, zero-latency connection to a console.
Side-by-Side: Which Should You Choose?
• Best for Xbox gaming → HyperX CloudX. Official licensing and a 3.5mm jack mean it just works with Xbox controllers.
• Best for voice chat → HyperX CloudX. A detachable, flexible noise-cancelling mic and in-line mute beat open-ear call mics for gaming.
• Best for staying aware of traffic → CXK Bone Conduction Headphones. Open-ear design keeps your surroundings audible; the CloudX seals you off.
• Best for battery life → CXK Bone Conduction Headphones. Up to 12 hours per charge, versus a wired headset that draws nothing.
• Best for latency-free audio → HyperX CloudX. Wired always beats Bluetooth for timing-sensitive gaming.
• Best for long-session comfort → HyperX CloudX. Memory foam over-ear cushions and a 297g aluminum frame are built for hours at a desk.
• Best for phone-free listening → CXK Bone Conduction Headphones. MP3 mode with storage for up to 8,000 songs means no phone required.
In my opinion, this isn't really a contest — it's a fork in the road. If your priority is gaming on an Xbox with a proper mic, real comfort and zero wireless hassle, I'd buy the HyperX CloudX. It's the more complete tool for that job, and the official licensing removes the usual compatibility headaches. If your priority is music while swimming, cycling or training outdoors, I'd buy the CXK Bone Conduction Headphones, because nothing about the CloudX is designed for water or for open-ear awareness. Buy for the activity you actually do most, not the spec sheet that looks most impressive. Check the current price on Amazon for whichever one matches your routine.
how to headphones work
A traditional headphone like the HyperX CloudX uses dynamic drivers — 5.3cm units here — that push air to create sound inside a sealed or semi-sealed ear cup. The CXK uses a bone conduction driver instead, a 12mm transducer that vibrates against your cheekbone and sends sound to your inner ear while leaving your ear canals open.
how to headphones on iphone
The CXK Bone Conduction Headphones pair over Bluetooth 6.0 with a roughly 33-foot range, so they connect to an iPhone the same way any Bluetooth audio device does. The HyperX CloudX is wired with a 3.5mm jack and no Bluetooth, so it needs a compatible 3.5mm port or an adapter — it's aimed at Xbox controllers, not iPhones.
how to headphones noise cancelling
Neither product listed here has active noise cancellation — both data sheets state noise control as none. The HyperX CloudX does include a detachable noise-cancelling microphone, which cleans up your voice going out, not sound coming in. The CXK relies on open-ear awareness plus AI noise-cancelling algorithms on its microphones for calls.
how to headphones waterproof
Only the CXK Bone Conduction Headphones are waterproof, rated IPX8 with a triple-seal design for immersion up to 2 meters for 2 hours. Remember to double-click the power button to switch to MP3 mode before entering the water, since Bluetooth can't connect underwater. The HyperX CloudX has no water resistance rating at all — keep it dry.
