• Wildhorn Outfitters Crank Bone Conduction — biggest strength: IPX8 waterproofing plus an MP3 mode holding up to 2,500 songs, so it works underwater where Bluetooth simply can't.
• Wildhorn Outfitters Crank Bone Conduction — biggest trade-off: Open-ear bone conduction means no noise isolation at all, and its 12-hour battery has to cover everything, with no charging case to top it up.
• Ordtop Sport — biggest strength: Up to 70 hours of total playtime via its charging case, with 4 ENC microphones and 14.2 mm dynamic drivers for punchy bass and clearer calls.
• Ordtop Sport — biggest trade-off: In-ear design blocks your surroundings, and Bluetooth doesn't transmit underwater — so it's a land-only headphone despite the IPX8 rating.
• Who each is for: Wildhorn for swimmers and open-water athletes who need audio in the pool; Ordtop for runners, gym-goers and commuters who want long battery life and strong sound.
The Crank is a niche product, and it's unapologetic about it. The core idea is bone conduction: instead of firing sound waves into your ear canal, it vibrates through your cheekbones to your inner ear. That's why the earpiece is open-ear, and why the titanium alloy frame and silicone-wrapped finish matter so much — the drivers sit against bone, so the padding and light weight (0.18 kg) are what keep long sessions comfortable. The silicone coating also reduces pressure on the cheekbones, which is exactly the kind of detail that separates a wearable swim headphone from a gadget you take off after ten minutes.
Buy it if you swim laps, train in open water, or want situational awareness while running and cycling — the open-ear design lets ambient sound in, which is a genuine safety advantage. Skip it if you want deep bass, noise isolation, or a charging case. Bone conduction trades bass response for safety and water capability. Also note it's bone conduction, not noise cancelling — the spec sheet lists no noise control at all, and that's by design.
Ordtop Sport: Who It's For
The Ordtop Sport plays a much more familiar game, and plays it well. It's a true-wireless in-ear bud with an earhook, IPX8 waterproofing and a nano-coating that keeps sweat and rain out. The 45° tilt-angle design and liquid silicone tips create a dual-lock fit that's meant to stay put during sprints, burpees and heavy bag work. At 35 g for the set, it's light enough to forget you're wearing them, and the in-ear seal gives you passive noise cancellation — good for focus, less good if you need to hear traffic.
The audio hardware is where it separates from cheap gym buds. Each bud houses a 14.2 mm dynamic driver, which is a large size for an in-ear, combined with a sound guide architecture for low-frequency rebound. Four built-in ENC microphones handle calls and reject surrounding noise. Battery life is the headline: 14 hours per charge, up to 70 hours total with the USB-C charging case, and a 15-minute quick charge yields 2 hours of listening. An LED display shows real-time battery status. Bluetooth 5.4 gives you faster pairing and better anti-interference than 5.3, and the 15-meter range is a step beyond the Wildhorn's 10 meters. Controls are push-button and touch, covering playback, volume, calls and voice assistance. Ordtop also backs it with a 30-day refund and 24-month repair policy.
Buy it if you run, lift, cycle or commute and want long battery life, strong bass and reliable call quality. Skip it if you swim — the IPX8 rating protects against sweat and rain, but Bluetooth can't transmit through water, so there's no underwater audio mode here.
Side-by-Side: Which Should You Choose?
• Swimming and underwater audio → Wildhorn Outfitters Crank Bone Conduction. IPX8 plus MP3 mode is the only way either product plays music in a pool.
• Situational awareness and safety → Wildhorn Outfitters Crank Bone Conduction. Open-ear design keeps you aware of traffic and surroundings.
• Noise isolation and focus → Ordtop Sport. In-ear fit with passive noise cancellation blocks the gym and the subway.
• Bass and sound quality → Ordtop Sport. Its 14.2 mm dynamic drivers are built for low-end punch; bone conduction inherently sacrifices bass.
• Phone-free workouts → Wildhorn Outfitters Crank Bone Conduction. Up to 2,500 songs and ~145 hours of stored audio, no phone required.
• Calls and meetings → Ordtop Sport. Four ENC microphones versus no microphone or call features listed for the Crank.
• Comfort over very long sessions → Wildhorn Outfitters Crank Bone Conduction. The titanium frame and silicone wrap minimize pressure on the cheekbones; the Ordtop's in-ear seal can fatigue ears over many hours.
If I had to pick one, I'd buy the Ordtop Sport — but only because most people work out on land. In my opinion, it's the better all-rounder: 70 hours of total playtime, real bass from 14.2 mm drivers, four microphones for calls and a secure earhook fit cover running, gym work and commuting without compromise. The Crank is the smarter buy only if swimming is your primary sport, because nothing else in this comparison delivers audio underwater. Match the tool to your training ground and you won't regret either.
Yes, and it's not close. The Crank is IPX8-rated for continuous immersion beyond one meter and has an MP3 mode that plays stored audio underwater, where Bluetooth can't reach. The Ordtop Sport is IPX8 too, but only for sweat and rain — it's a land headphone.
Ordtop Sport, clearly. It runs 14 hours per charge and up to 70 hours total with its charging case. The Crank gives you 12 hours with no case, though a 10-minute magnetic top-up adds an hour when you're in a hurry.
That's exactly what they're built for. The 45° tilt-angle design, silicone ear tips and earhooks create a dual-lock fit, and the set weighs only 35 g, so they're designed to stay put through sweaty, high-movement training.
Prices change, so check the current price on Amazon for both — this page has a button for that. In my opinion, the Ordtop Sport is the better value for land athletes because you get far more battery life, bigger drivers and call features, while the Crank's value is entirely tied to whether you swim.
