• SilisoundTek's biggest strength: 10 hours of playtime from a 230mAh battery with fast 1.5-hour magnetic charging, plus Bluetooth 5.3 and hybrid noise cancellation for calls.
• SilisoundTek's biggest trade-off: Despite the IP68 rating, the listing itself says it is not suitable for swimming, so treat it as a sweat-and-rain sports headphone, not a pool headphone.
• ANSTEN's biggest strength: True dual-mode design — Bluetooth 5.4 plus a built-in 8GB MP3 player holding up to 1500 songs, so it keeps playing where Bluetooth signal can't reach, like underwater.
• ANSTEN's biggest trade-off: Shorter battery life (8 hours, 2-hour charge), no noise cancellation, and a lighter ABS/silicone frame that feels less premium than metal.
• For cyclists who want all-day open-ear audio and clear calls → SilisoundTek Bone Conduction Headphones.
• For swimmers who want music in the water plus cycling and running → ANSTEN Swimming Headphones.
The SilisoundTek S800 is built around one idea: keep your ears completely open while you ride. Bone conduction drivers push sound through your cheekbones instead of into your ear canal, so traffic, bells and other riders stay audible. That open-ear approach is the whole point for cycling — you get music without sealing yourself off from the road, which is exactly the safety argument the listing leans on.
The spec sheet backs up the "long ride" pitch. A 230mAh battery is rated for 8–10 hours of continuous music or calls, and the magnetic charger tops it up in about 1.5 hours. Bluetooth 5.3 brings lower latency and better interference resistance than the older 5.2 standard, with a 10-metre range. The wrap-around titanium alloy frame bends 360° without deforming, and at 32g it's designed to stay put through hard efforts without pressure points. A hybrid noise-cancelling mic handles calls, and the 8-ohm bone conduction driver covers a 20Hz–20,000Hz range.
ANSTEN Swimming Headphones: Who It's For
The ANSTEN S870 is the more specialised tool. Its headline feature is dual-mode playback: Bluetooth 5.4 for normal wireless listening, and a built-in 8GB MP3 player with room for up to 1500 songs. A double-click on the function key switches modes. That matters because Bluetooth signals don't travel through water — the MP3 mode is what lets this headphone keep playing when you're actually submerged, which is the core reason a swimmer would pick it over anything else.
It's also the lighter of the two at 24.3g, with an open-ear bone conduction design and an ABS/silicone frame. The 180mAh battery gives up to 8 hours of music or calls, with a full charge in about 2 hours. The IP68 rating covers swimming and water sports, and the listing notes it works alongside a swim cap, goggles and earplugs — earplugs are even included in the box, along with adjustable elastic straps and two magnetic charging cables. Controls are simple push-button, covering playback, calls and voice assistants.
Who should buy it: swimmers first, but also cyclists, runners and surfers who want one headphone that works both in and out of the water. Who should skip it: riders who want the longest possible battery, active noise cancellation for calls, or a metal frame — the ANSTEN gives up all three, and its 8-hour rating is the shorter of the pair.
• Best for battery life → SilisoundTek Bone Conduction Headphones. 10 hours vs 8 hours, and a faster 1.5-hour charge vs 2 hours.
• Best for cycling safety and awareness → either, but SilisoundTek edges it. Both are open-ear, but the titanium alloy frame and hybrid noise-cancelling mic suit long road sessions and calls better.
• Best for wireless connectivity → ANSTEN Swimming Headphones. Bluetooth 5.4 is a step ahead of 5.3, though both manage a 10-metre range.
• Best for phone calls → SilisoundTek Bone Conduction Headphones. It has a built-in noise-cancelling microphone; the ANSTEN lists noise control as none.
• Best for lighter wear → ANSTEN Swimming Headphones. 24.3g vs 32g, with a silicone-heavy build that sits softly on the head.
• Best for build durability → SilisoundTek Bone Conduction Headphones. The metal enclosure and bendable titanium frame suggest a tougher long-term frame than ABS plastic.
• Best for one-device-does-everything → ANSTEN Swimming Headphones. Bluetooth 5.4, MP3 storage, and a waterproof rating explicitly aimed at the pool.
My Verdict
If I'm buying for cycling, I'd take the SilisoundTek Bone Conduction Headphones. In my opinion the combination of 10-hour playtime, a 1.5-hour magnetic charge, Bluetooth 5.3, a noise-cancelling mic and a bendable titanium frame is the better fit for long rides, commutes and training where calls and battery matter more than pool time. I'd only switch to the ANSTEN Swimming Headphones if swimming laps with music is a genuine part of your routine — its 8GB MP3 mode is something the SilisoundTek simply can't match. For a pure cyclist, the SilisoundTek is the more complete everyday headphone.
FAQ
Yes — both use open-ear bone conduction, so you hear traffic while you ride. The SilisoundTek adds a longer 10-hour battery and a noise-cancelling mic, which makes it the stronger pick for longer road sessions and taking calls on the move.
The listing says no — it states they are not suitable for swimming, even though the rating is IP68. Treat them as sweat-, rain- and dust-proof sports headphones. For actual swimming, the ANSTEN's IP68 rating and 8GB MP3 mode are what you want.
SilisoundTek: 8–10 hours from a 230mAh battery, charged in about 1.5 hours. ANSTEN: up to 8 hours from a 180mAh battery, charged in about 2 hours. So the SilisoundTek wins on both runtime and charge speed.
Only the SilisoundTek lists hybrid noise cancellation, and it also has a built-in noise-cancelling microphone for calls. The ANSTEN lists no noise control, so it relies purely on the open-ear bone conduction design.
