If you want a pair of sport earbuds built to stay put through hard training and long weeks between charges, choose Matast Earbuds; if you need earbuds with a rapid top-up for last-minute use and a wider wireless leash, choose Monster Achieve 100.
• Matast Earbuds biggest strength: 50 hours of total playtime with a dual LED display that shows exactly how much charge is left in the case and in each bud, plus a flexible ear-hook fit and IP7 waterproofing aimed squarely at workouts.
• Matast Earbuds biggest trade-off: It's a sport-first design with a hook-style in-ear fit, so if you want a plain bud that disappears in your ear, the shape may feel like more hardware than you want.
• Monster Achieve 100 biggest strength: Super fast charging — 10 minutes of charge is rated for 120 minutes of playback — and a Bluetooth range of up to 30 meters, double the Matast's 15 meters.
• Monster Achieve 100 biggest trade-off: The battery math is different rather than bigger, its charging case tops out around 24 hours of total playtime versus the Matast's 50, and it uses older Bluetooth 5.0 instead of 5.4.
• Who each pick is for: Matast Earbuds for runners, gym-goers and anyone who hates charging; Monster Achieve 100 for people who forget to charge, want push-button controls, and value a wider roaming range.
The Matast Earbuds are unapologetically a sport pair. The spec sheet reads like a checklist for people who sweat: flexible ear hooks, three sizes of ear caps, and an IP7 nano-coating waterproof rating for splashes, sweat and rain. That combination matters more than it sounds. Most earbuds fall out of a sweaty ear during a run, and the hook design is the simplest fix there is. If your workouts involve movement — sprint intervals, burpees, treadmill hills — this is the design language you want.
Sound is handled by a 13mm dynamic driver covering 20Hz to 20,000Hz, which is the standard full-range window but with a notably large driver for this class. In practice, a bigger driver is usually what gives you the deep bass the product is built around. For calls, there are four ENC noise-cancelling microphones that the spec says passively cut around 80% of background noise, so your voice should come through in a noisy gym or on a windy street. That's a real advantage over earbuds with a single mic, because multiple mics give the processing more to work with.
The battery story is the headline. Ten hours per charge, 50 hours total with the case, a 1.5-hour full recharge over USB-C, and a dual LED display that shows remaining case power and per-bud charging progress. Anyone who has stared at a single blinking LED guessing whether they have 20% or 2% will appreciate that detail. Bluetooth 5.4 is also the newer standard here, and Matast claims roughly double the data speed and 30% lower power draw versus 5.3, with a 15-meter range.
Monster Achieve 100: Who It's For
The Monster Achieve 100 AirLinks leans on a different pitch. Monster is a long-established audio brand, and this model is tuned around what the company calls Pure Monster Sound — a digital audio processor pushing deep bass while lifting mid and high definition, with dynamic drivers covering the same 20Hz–20,000Hz range. Whether that tuning suits you is personal taste, but the design intent is clear: bass-forward, energetic sound rather than a flat studio profile.
The genuinely useful feature is fast charging. Ten minutes in the case is rated for 120 minutes of playback, and the case extends total listening to roughly 24 hours, with a claimed 260 minutes from a single charge of the buds. That's a "I forgot to charge and I'm walking out the door" feature, and for commuters it's arguably worth more than a bigger total number. Bluetooth 5.0 with a 30-meter range is older than the Matast's 5.4, but the range figure is better, and 5.0 remains perfectly stable for phone-to-earbud duty.
Fit is handled with three pairs of SportClips and three pairs of ear tips in small, medium and large — six options in total, which is generous and helps with the passive noise isolation that comes from a good seal. There's a built-in mic for calls, and you can use either one or both buds. Controls are push-button rather than touch, which some people strongly prefer because buttons give you a physical click you can feel through a jacket or gloves. The design is also water resistant for gym and outdoor use, though note the spec sheet doesn't assign it a numeric IP rating the way the Matast does.
Who should buy it: commuters, casual listeners, anyone who wants physical buttons, and people who regularly forget to charge. Who should skip it: if you want the longest total battery life, the newest Bluetooth version, or ear hooks for serious running, the Matast covers those better. Again, check the current price on Amazon to judge the value for yourself.
• Best for total battery life → Matast Earbuds. 50 hours total versus roughly 24 hours on the Monster, with 10 hours per single charge.
• Best for emergency top-ups → Monster Achieve 100. 10 minutes of charging for 120 minutes of playback is the standout spec on this sheet.
• Best for secure workout fit → Matast Earbuds. Ear hooks plus three ear cap sizes are purpose-built to stop slippage during vigorous exercise.
• Best for wireless range → Monster Achieve 100. Up to 30 meters versus 15 meters on the Matast.
• Best for the newest Bluetooth → Matast Earbuds. Bluetooth 5.4 with claimed faster transmission and lower power draw beats 5.0 on paper.
• Best for call clarity in noise → Matast Earbuds. Four ENC microphones rated to passively cancel about 80% of background noise is a stronger mic setup than a single built-in mic.
• Best for physical buttons → Monster Achieve 100. Push-button control instead of touch, which suits gloved hands and cold-weather use.
• Best for charging visibility → Matast Earbuds. The dual LED display shows case power and per-bud charging progress instead of a vague indicator.
In my opinion, the Matast Earbuds are the better buy for most people shopping this comparison. The 50-hour battery, IP7 waterproofing, ear-hook fit and four-mic call setup line up with how earbuds actually get used — workouts, commutes, long days away from a charger. The Monster Achieve 100 is the smarter pick in one specific scenario: if you constantly forget to charge and need two hours of playback from a ten-minute top-up, or you want push buttons and a longer wireless leash. Otherwise, I'd take the Matast.
For running, yes, in my opinion. The ear hooks, three ear cap sizes and IP7 waterproof rating are built for sweat and movement, while the Monster relies on SportClips and a general water-resistant design without a numeric IP rating in its specs.
Matast is longer overall at 50 hours total with the case and 10 hours per charge. Monster is shorter at roughly 24 hours total, but it charges far faster — 10 minutes for 120 minutes of playback versus a 1.5-hour full charge on the Matast.
Not on version — Monster uses Bluetooth 5.0 while Matast uses 5.4. But Monster lists a longer range at up to 30 meters versus 15 meters on the Matast, so range favors Monster while recency and power efficiency favor Matast.
The Matast Earbuds have the stronger call setup on paper, with four ENC noise-cancelling microphones rated to passively cancel around 80% of background noise. The Monster has a single built-in mic but supports using either bud alone for calls, which some people find more convenient.
