How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want marathon battery life in a tiny, sweat-proof package with a bass-forward tuning, choose XIAOWTEK Earbuds; if you need real active noise cancellation and big over-ear drivers for deep bass, choose Monster Active Noise Cancelling.
• XIAOWTEK Earbuds — biggest strength: up to 50 hours of total playback with the charging case, an IP7 waterproof build, and a 13.4 mm graphene diaphragm tuned for deep bass in a 4-gram-per-bud design.
• XIAOWTEK Earbuds — biggest trade-off: noise control is passive only, so it blocks sound by sealing your ear canal rather than cancelling it electronically.
• Monster Active Noise Cancelling — biggest strength: active noise cancellation that Monster says blocks up to 98% of ambient noise, plus 40 mm drivers and a 40-hour ANC / 60-hour standard battery.
• Monster Active Noise Cancelling — biggest trade-off: it's a full over-ear headphone at 8 ounces with a foldable frame, so it's bulkier to carry and not built for sweaty workouts.
• Who each pick is for: XIAOWTEK for runners, commuters and pocket-carriers who want long battery and deep bass on the move; Monster for home, office and travel listeners who want to shut the world out entirely.
The XIAOWTEK Earbuds (model A66) are built around one idea: stay in your ears, stay out of your way, and keep playing. Each bud runs up to 8 hours on its own, and the case pushes total playback to a claimed 50 hours. That's the kind of number that matters if you're the person who forgets to charge things — you can go days of normal commuting without hunting for a cable. A dual LED display on the case shows the power level, which sounds minor until you've owned a case that just blinks at you and tells you nothing.
The sound story is where the "deep bass" angle gets real. XIAOWTEK uses a 13.4 mm graphene diaphragm driver, and the frequency range is listed at 20Hz–20,000Hz — that 20Hz floor is what you want to see if you care about low-end rumble rather than just thump. In my experience reading specs like this, graphene diaphragms tend to hold their composure better than cheap paper drivers when you push volume, so bass stays punchy instead of muddy. Add Bluetooth 5.4 for a stable connection, auto-pairing the moment you lift them out of the case, and touch controls for playback and calls, and you've got a very complete little package.
The practical stuff is genuinely strong. IP7 waterproofing means sweat, rain and splashes are a non-issue, which is exactly what you want for running or gym work. Each bud weighs 4 grams, and the case has a lanyard so you can clip it to a bag or keys. Calls run through dual hybrid ENC microphones that XIAOWTEK says passively eliminate 85% of background noise.
Who should skip it: if your main goal is silencing a noisy office, a plane cabin, or a loud household, passive noise cancellation won't get you there. And if you want the physical feel of ear cups around your ears, in-ears are the wrong shape entirely.
Monster Active Noise Cancelling: Who It's For
The Monster Persona SE ANC is a different animal. This is an over-ear headphone, and the headline feature is the ANC button: Monster states the digital noise cancellation algorithm blocks up to 98% of ambient noise. That's the number that separates this from the XIAOWTEK. Passive isolation is a seal; active cancellation is electronics fighting the noise for you. On a plane, in a shared office, or next to a running appliance, that distinction is the whole reason you'd pick this one.
Sound is the second pillar. Monster pairs a digital audio processor with 40 mm dynamic drivers and markets its "Pure Monster Sound" tuning as balanced with powerful, deep bass. Bigger drivers physically move more air, so a 40 mm over-ear design has a natural advantage in low-end weight and presence that a small in-ear simply can't match. The frequency response is listed up to 20KHz. If deep bass is your priority and you're listening at a desk or on a sofa rather than on a treadmill, this is the more satisfying listen of the two.
Battery is where it gets interesting. Monster claims up to 40 hours of music with ANC on, and up to 60 hours in standard mode — so turning off noise cancellation buys you a lot of extra runtime. Type-C fast charging adds roughly 4 hours of listening from a 5-minute top-up, and a full charge takes about 2 hours. Bluetooth 5.4 with a 33-foot range handles the wireless side, and it auto-connects after the first pairing.
Comfort is clearly the design focus. Protein leather ear cups with memory foam padding, an adjustable headband for different head sizes, and a foldable frame for storage. At 8 ounces it's light for an over-ear, and Monster positions it for home use — long sessions at a desk, on the couch, or through a workday.
Who should buy it: home listeners, remote workers, frequent flyers, and anyone who wants ANC plus genuinely big bass in an over-ear design they can wear for hours.
Who should skip it: if you run, lift, or commute on a bike, an 8-ounce over-ear headphone is the wrong tool. And if you want something that disappears into a jeans pocket, this isn't it.
• Best for deep bass on the move → XIAOWTEK Earbuds. The 13.4 mm graphene driver and 20Hz low-end are tuned for punchy bass in a 4-gram bud.
• Best for deep bass at home → Monster Active Noise Cancelling. 40 mm drivers move more air; that's physics doing the work.
• Best for blocking out the world → Monster Active Noise Cancelling. Active cancellation up to 98% of ambient noise versus XIAOWTEK's passive seal.
• Best for total battery life → XIAOWTEK Earbuds. 8 hours per bud and 50 hours with the case is hard to beat for something this small; Monster's 40-hour ANC / 60-hour standard mode is strong but the case-free earbuds win on sheer endurance per carry.
• Best for workouts and weather → XIAOWTEK Earbuds. IP7 waterproofing against sweat, rain and splashes; the Monster's faux leather and memory foam aren't built for that.
• Best for long desk sessions → Monster Active Noise Cancelling. Memory foam ear cups, an adjustable headband and a foldable frame are made for hours of seated listening.
• Best for portability → XIAOWTEK Earbuds. A compact case with a lanyard clips to a bag or keys; the Monster folds but still takes up real space.
• Best for calls in noisy places → Monster Active Noise Cancelling. ANC plus a built-in mic does more for you in a loud room than ENC microphones alone.
In my opinion, the honest answer depends on where you listen most. If most of your listening happens at a desk, on a plane, or on a couch — and you want silence plus real low-end weight — I'd buy the Monster Active Noise Cancelling (B0H94BDJ98). The active cancellation and 40 mm drivers are a combination the XIAOWTEK simply can't replicate, and the memory foam cups are built for long sessions. But if you want one pair that survives rain, sweat, the gym and your pocket, and still delivers deep bass, I'd go XIAOWTEK — the 50-hour case, IP7 rating and 4-gram fit are the more versatile everyday choice. Check the current price on Amazon before you decide, since that's the one variable this comparison can't cover.
Monster, clearly. The Persona SE ANC uses active noise cancellation that Monster says blocks up to 98% of ambient noise. XIAOWTEK relies on passive noise cancellation — a physical ear seal — which helps but won't match electronic ANC.
Both are marketed for deep bass, but the Monster's 40 mm dynamic drivers move more air than XIAOWTEK's 13.4 mm diaphragm, so expect more low-end weight from the over-ear. XIAOWTEK's graphene driver still delivers punchy, clear bass in a far smaller package.
I wouldn't recommend it. It's an 8-ounce over-ear with protein leather and memory foam cups and no waterproof rating listed. XIAOWTEK's IP7 rating and 4-gram buds are the better fit for running, the gym and rain.
XIAOWTEK claims 8 hours per bud and up to 50 hours total with the case. Monster claims 40 hours with ANC on and 60 hours in standard mode. For a single carry, XIAOWTEK's case-backed total is the longer number; Monster wins if you leave ANC on and never want a case.
