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 in-ear package that works with virtually any phone, choose ELOVEN Earbuds Deep Bass; if you need serious over-ear noise cancellation and big, physical bass for home listening, choose Monster Active Noise Cancelling. That's the short version. The longer version comes down to one question: do you want something light you forget you're wearing, or something big that shuts the world out?
• ELOVEN Earbuds Deep Bass — biggest strength: true wireless in-ear design with up to 120 hours of battery life and a charging case, plus three sizes of wing tips for a secure fit.
• ELOVEN Earbuds Deep Bass — biggest trade-off: it's a compact in-ear bud, so it relies on noise reduction processing rather than the physical isolation of an over-ear cup.
• Monster Active Noise Cancelling — biggest strength: over-ear active noise cancellation rated to block up to 98% of ambient noise, with 40mm dynamic drivers tuned for deep bass.
• Monster Active Noise Cancelling — biggest trade-off: it's a full-size over-ear headphone with a foldable but larger body, so it's built more for home and desk use than for stuffing in a pocket.
• Pick ELOVEN if you want all-day wireless listening from a case that charges and travels easily.
• Pick Monster if you want maximum quiet and room-filling bass in one over-ear package.
The ELOVEN Earbuds Deep Bass is a true wireless in-ear set built around convenience. You get the buds, a charging case, a charging cable, and three wing tip sizes (S/M/L) in the box. That last detail matters more than it sounds: in-ear buds only perform well when they actually seal in your ear, and having three tip sizes means you can dial in that seal instead of fighting a one-size-fits-all fit. The rounded-tip design and 16-ohm impedance make them easy to drive from any phone.
The headline spec here is battery. ELOVEN lists up to 120 hours of standby time, and the charging case carries that same 120-hour figure, so the case is doing the heavy lifting of keeping the buds topped up between sessions. For someone who listens on commutes, at a desk, or during workouts, that's the whole appeal — you drop them back in the case and stop thinking about charging. Bluetooth 5 keeps the connection stable within a 10-meter range, which covers a room or a backyard without drama.
Control is all touch-based: tap to play, pause, skip, or take a call. The buds also carry an active noise cancellation mode that adjusts volume on its own, and the build is described as anti-sweat and suitable for indoor and outdoor exercise — with the reasonable warning not to run them through a washer or dryer.
Who should skip it: if your main goal is to silence a noisy room and you want the deep, physical thump of a large driver, an in-ear bud won't deliver the same experience as an over-ear can. That's not a flaw — it's a different category.
Monster Active Noise Cancelling: Who It's For
The Monster Active Noise Cancelling is a different animal entirely. This is an over-ear headphone — model Monster Persona SE ANC — with protein leather earcups over memory foam padding, an adjustable headband, and a foldable frame. Monster states the ANC algorithm blocks up to 98% of ambient noise when you press the ANC button. If you've ever tried to work or relax next to a droning appliance, a busy street, or a chatty open-plan office, that number is the reason this product exists.
Sound is the second pillar. Monster uses 40mm dynamic drivers paired with its Pure Monster Sound processing, and the marketing leans hard into "big bass, deep bass." A 40mm driver is simply a bigger physical piston than what fits in an in-ear bud, and that's the honest mechanical reason over-ear headphones generally move more air and hit lower with more authority. The frequency response tops out at 20 KHz. The wired jack is absent — this is wireless-only over Bluetooth 5.4, which brings lower latency and a more stable connection than older Bluetooth versions, with a range around 33 feet.
Battery is strong but not endless: up to 40 hours with ANC on, up to 60 hours in standard mode, and a Type-C fast charge that Monster says gives you about 4 hours of listening from a 5-minute charge. Full charge takes about 2 hours. There's a built-in mic for calls, and the whole thing is button-controlled rather than touch, which some people genuinely prefer because there's no accidental tapping.
Who should buy it: home listeners, remote workers, students, and anyone who wants to block out a room and feel bass rather than just hear it. The memory foam and adjustable headband suit long sessions, and the foldable design helps when you do travel with it.
Who should skip it: if you want something that disappears into a pocket, or you need buds for sweaty gym sessions, this is the wrong shape. Over-ear headphones are a commitment — you wear them, you don't forget them.
• Best for battery life → ELOVEN Earbuds Deep Bass. Up to 120 hours of standby with a charging case beats 40–60 hours of playtime.
• Best for maximum noise blocking → Monster Active Noise Cancelling. Up to 98% of ambient noise blocked is a fundamentally different level of quiet than in-ear noise reduction.
• Best for bass you can feel → Monster Active Noise Cancelling. 40mm dynamic drivers and Pure Monster Sound are built around deep, punchy low end.
• Best for workouts and moving around → ELOVEN Earbuds Deep Bass. Anti-sweat in-ear buds with three wing tip sizes stay put; over-ear cups get hot and slide.
• Best for calls and quick touch controls → ELOVEN Earbuds Deep Bass. Tap-to-control and a mic in a tiny package is the more natural phone companion.
• Best for long desk sessions and home listening → Monster Active Noise Cancelling. Memory foam earcups and an adjustable headband are made for hours at a time.
• Best for travel convenience → ELOVEN Earbuds Deep Bass. A small charging case wins over a foldable full-size headphone for pocket space.
• Best for pairing stability and low latency → Monster Active Noise Cancelling. Bluetooth 5.4 edges out Bluetooth 5 on paper.
In my opinion, these two aren't really competing — they solve different problems, and that's exactly why the choice is clean. If I had to pick one for most people's daily life, I'd take the ELOVEN Earbuds Deep Bass, because a case that keeps them charged, a fit you can customize with three tip sizes, and a form factor you can carry anywhere covers more of the average day. But if quiet is the point — if you need to erase a noisy room and want bass with real weight — I'd buy the Monster Active Noise Cancelling without hesitating. Decide which of those two matters more to you, and the answer picks itself.
FAQ
On paper, yes — and by a wide margin. Monster states its ANC blocks up to 98% of ambient noise, while ELOVEN's in-ear design relies on noise reduction processing plus whatever seal the wing tips give you. For silencing a room, the over-ear Monster is the stronger tool.
Yes. ELOVEN lists compatibility across a long list of Samsung Galaxy phones and iPhones, plus iPads, and uses Bluetooth 5 at roughly a 10-meter range. The Monster is wireless-only too, with no headphone jack, and pairs over Bluetooth 5.4 at about 33 feet.
