• Yoidesu Charging Cable — biggest strength: It is a dedicated, fast-charging USB replacement cord built specifically for the AfterShokz AS800 and ASC100, with multi-layer protection (short circuit, overvoltage, overload filtering) and low working temperature for a long service life.
• Yoidesu Charging Cable — biggest trade-off: It only charges those specific headsets — it is not a universal cable and it does not play audio, so it is useless if you need earbuds.
• Monster Achieve 100 — biggest strength: It is a full true-wireless earbud system with Bluetooth 5.0, a USB-C charging case, super-fast charging (about 10 minutes for roughly 120 minutes of playback), and a built-in mic for calls.
• Monster Achieve 100 — biggest trade-off: It is a wireless audio product, not a cable — it will not replace a lost charging cord for your AfterShokz headset.
• Who each pick is for: Choose the Yoidesu cable if you already own an AS800 or ASC100 and need a reliable replacement charger. Choose the Monster Achieve 100 if you want a new pair of earbuds for music, calls, and workouts.
The Yoidesu Charging Cable is a narrow-purpose product, and it is honest about that. It is a USB charging cord made of premium TPE, designed to replace a lost or worn-out charger for the AfterShokz AS800 and AfterShokz ASC100 Bluetooth headsets. That is its entire job. It is a male-to-female connector with 4 pins, rated for indoor and outdoor use, and it weighs just 16 grams — the kind of thing you can leave in a bag or a desk drawer and forget about until you need it.
What it does best is the unglamorous stuff. According to the spec sheet, it runs at a low working temperature, which matters for a cable you might leave plugged in for long stretches — heat is the enemy of cord longevity. It also lists multi-protection features: output short circuit protection, overvoltage protection, and overload filtering, plus good anti-interference performance. Those are the safety layers that keep a cheap-feeling replacement cord from damaging the device it is charging. Yoidesu also claims fast charging with low DC ripple and high working efficiency, which in plain terms means it should top up your headset quickly rather than trickling.
Who should buy it? If you own an AfterShokz AS800 or ASC100 and your original cable has frayed, gone missing, or stopped making a solid connection, this is the straightforward fix. It is also a reasonable backup to keep in a second location. Who should skip it? Anyone who does not own one of those two headset models. If your headset is a different brand or model, this cable is not built for you, and you should look for a cord matched to your specific device. If you are shopping for earbuds rather than a cable, this is simply the wrong product category — keep reading.
The Monster Achieve 100 AirLinks is a completely different animal: a set of true-wireless in-ear earbuds in red, with a USB-C charging case and Bluetooth 5.0. It is built around what Monster calls Pure Monster Sound, with a dynamic driver covering a 20Hz–20,000Hz frequency range, a digital audio processor tuned to lift bass while keeping mids and highs clear, and a claimed wider soundstage for better accuracy across the spectrum. Whether the tuning suits your ears is a matter of taste, but the hardware description is specific and detailed.
The standout spec is charging speed. The earbuds are rated for super-fast charging — about 10 minutes of charge for roughly 120 minutes of playback — and a single full charge is rated at more than 260 minutes, with the charging case extending total listening to around 1440 minutes. The battery charge time listed is 260 minutes. That combination makes these a strong candidate for people who constantly forget to charge and need a quick top-up before a commute or a workout. Bluetooth 5.0 gives a wide wireless range (listed at 30 meters) and stable pairing, with one-step reconnection after the first setup.
For calls, there is a built-in microphone that Monster says keeps voices clear even in noisy settings, and you can use one or both earbuds. Controls are push-button via a multi-function button, so you can answer calls, switch tracks, adjust volume, and even trigger your phone's voice assistant with a double-click. The earbuds are described as ergonomic and lightweight, and they ship with three pairs of SportClips and three pairs of eartips in S, M, and L — six fit options total. The design is listed as water resistant for sports and outdoor use, and there is a 1-year manufacturer warranty.
Who should buy it? Anyone who wants a self-contained wireless listening setup for music, calls, gym sessions, and daily wear, and who values fast charging and long total playtime. Who should skip it? If you specifically need a replacement charging cable for an AfterShokz headset, this does not solve that problem at all. It is also a wireless product, so there is no jack — if you need a wired connection, look elsewhere.
• Best for replacing a lost AfterShokz AS800 or ASC100 charger → Yoidesu Charging Cable. It is purpose-built for exactly those two models.
• Best for listening to music and taking calls wirelessly → Monster Achieve 100. It is a full earbud system, not an accessory.
• Best for long battery life and fast top-ups → Monster Achieve 100. Rated for 260+ minutes per charge, 1440 minutes with the case, and 10 minutes for about 120 minutes of play.
• Best for a lightweight, packable backup → Yoidesu Charging Cable. At 16 grams with a round black TPE build, it disappears into any bag.
• Best for workouts and outdoor use → Monster Achieve 100. It carries a water-resistant design and ships with SportClips.
• Best for charging safety on a budget accessory → Yoidesu Charging Cable. Short circuit, overvoltage, and overload filtering are explicitly listed.
• Best for fit flexibility → Monster Achieve 100. Six eartip and SportClip options across S, M, and L.
• Best for a one-device, one-job fix → Yoidesu Charging Cable. If your headset just needs power, this is the simplest answer.
In my opinion, these two products should not really be competing for the same slot in your cart — they solve different problems. If you own an AfterShokz AS800 or ASC100 and your cable has failed, I would buy the Yoidesu Charging Cable without overthinking it. It is built for that exact job, and the protection features make it a sensible replacement. If you actually want earbuds for music, calls, and workouts, I would buy the Monster Achieve 100 instead — the fast-charge spec and long total playtime are the real selling points. Match the product to the problem you have, and you will not regret either purchase.
Based on the spec sheet, it is listed as applicable to the AfterShokz AS800 and ASC100 only. It is a male-to-female USB connector with 4 pins, so I would treat it as a model-specific replacement rather than a universal cable.
Monster rates it for super-fast charging: about 10 minutes of charge for roughly 120 minutes of playback, with a full single charge rated at more than 260 minutes and the case extending total playtime to around 1440 minutes. That quick top-up is the headline feature.
They are not comparable on value because they are different categories — one is a charging cable, the other is a full earbud system. Judge each against its own purpose. For current pricing on either, use the button on this page to check on Amazon.
It can replace it as your listening device, since it is a full wireless earbud system with a mic and call controls. But it will not charge an AfterShokz headset, and it has no wired jack — so if you specifically need to power an AS800 or ASC100, you still need the Yoidesu cable.
