MOXKING M2 Wired Durable Metal Earbuds Review
The MOXKING M2 pairs solid aluminum housings with a 3-button in-line remote on a 140cm cord, and it ships with five tip sizes (small, medium, large, triple-flange, and double-flange) to chase a seal. It is a wired, noise-isolating earbud aimed at people who want a metal build and basic call controls without stepping into wireless territory. What follows is a listen-based verdict on where the M2 lands sonically and how it holds up in daily use.

What’s Inside
The M2 uses a dynamic driver, the same transducer type found in most compact wired earbuds. The driver sits inside a machined aluminum shell, and the ear tip forms the seal against the ear canal wall. The product documentation describes the output as “powerful deep bass, high resolution mids and crisp highs” across the frequency range, but no driver diameter, chamber volume, vent size, or impedance figure is published in the available sources.

What the documentation does specify is the tip system. Five pairs of silicone tips are included, ranging from a small conical tip to a triple-flange design that adds two extra ridges for a deeper grip in the canal. The metal shell itself is not detachable from the cable; the 3.5mm plug, the Y-joint, and both bud housings are machined from a single aluminum stock, which means the acoustic cavity is a fixed, sealed chamber with no user-adjustable vent or bass port.
The Tuning
The M2 delivers a clear, mid- and treble-forward signature, and the bass response that many owners seek becomes audible only once the seal is fully seated. Several listeners describe the upper mids and treble as crystalline, while bass presence shifts dramatically depending on which tip size achieves airtight occlusion.
Mids and Treble
Classical music is a useful litmus for this band. One owner tested the M2 against well-recorded classical tracks and found the performance close to that of more expensive earphones in the same compact-wired category. For speech-heavy content, the midrange clarity translates directly to phone calls: the far-end listener reports a clean, uncolored voice, and the built-in microphone, per multiple owners, holds up even in moderately windy outdoor conditions. The treble does not peak or sibilate in the listening reports that come through, which keeps long vocal sessions with podcasts and audiobooks from turning fatiguing.
Bass
Bass is where owner experience splits. One listener found the low end unremarkable when the tips were not fully seated. Another, after cycling through all five tip sizes until the triple-flange option produced a proper seal, reported bass that closely matched a discontinued pair of scosche earbuds they had used for years. The gap between those two experiences is a function of fit, not of a different driver: the same dynamic transducer produces a bass boost, but the silicone seal determines whether that energy reaches the canal or leaks out around the tip. For gaming, the low-end punch registers impacts and engine notes without distortion, though it will not reach the sub-bass depth of a larger-driver wired set.
Overall Balance
The balance across the three bands skews toward the top two. In practical listening, the M2 sits forward in the vocal range and rolls off gently in the deepest lows unless the seal is airtight. That tuning suits talk-heavy content, pop, rock, and casual gaming where clarity of dialogue and midrange instrument detail matters more than sub-bass extension.
Fit, Tips and Seal
The M2 ships with five pairs of silicone tips: Small, Medium, Large, Triple-flange, and Double-flange. The flanged tips add an extra ridge that grips the canal wall more firmly, and owners with smaller ear canals have reported finding a secure fit by stepping down to the Small conical tip. The aluminum housing is heavier than a typical plastic earbud, and two separate owners note that the weight makes the buds slowly migrate outward over a listening session. Pushing them back in periodically restores the seal, and the triple-flange tips help lock the shell in place against that outward pull.
One buyer observed that the bud body itself runs a touch long, so even with the smallest tip the shell can protrude slightly from the outer ear. None of this is a manufacturing defect so much as a fit variable. The right tip size for your canal, matched to the M2’s longer body, determines whether the buds stay put or need readjusting every few minutes.
Once sealed, the M2 provides passive isolation by occluding the ear canal. Owners describe the set as “drowning out” ambient office hum and traffic noise at low listening volumes, which is useful for travel and commuting. The isolation is purely mechanical. Active noise-cancellation circuitry is absent from the design, and a loud environment will still bleed through the sealed canal. For the specific use of blocking wind during outdoor phone calls, one owner reported that the M2 handles a fair amount of wind but does not remove all of it.
Cable, Plugs and Build
The cord is 140cm (55in) of thick, tangle-resistant wire with reinforced filaments inside the jacket. The plug is a 3.5mm gold-plated connector, and the Y-joint where the two earbud wires meet the main cable is machined metal rather than the thin plastic housing most stock earbuds use. All three contact points, the bud housings, the Y-joint, and the plug, are solid aluminum, which gives the set a weighted, solid feel in the hand.

The in-line remote carries three buttons for play/pause, track skip, and call handling, plus a volume dial and a microphone element for hands-free talking. A small carrying pouch is included for stowing the buds between uses. The cable is fixed to the metal Y-joint and cannot be replaced independently, so a frayed section or a chewed-through jacket means replacing the entire set.
Time With the Music
Owner listening reports paint a consistent picture: the M2 suits talk-and-music hybrids, casual gaming, and commuter listening more than it suits a critical audiophile reference rig.
For daily commutes and long car rides, the clear mids and treble keep vocals and instrumental detail forward without fatigue. One owner uses the M2 for running and reports that after four to five months of regular workout use, the set still handles well with no audible degradation or cable fatigue. The 140cm cord gives enough reach to a phone in a jacket pocket without yanking the buds from the ear.
For PC and mobile gaming, the in-line remote matters. Owners who play with a squad on voice chat confirm that the microphone is legible to teammates and that the volume buttons let you ride levels without reaching for a device. The lack of a control function on older iPods, desktop PCs, and Kindle tablets is a known limitation: those platforms will carry audio through the 3.5mm jack but will not respond to the in-line buttons.
Where the M2 fades is in scenarios demanding deep, sustained sub-bass or planar-level treble resolution. It is a dynamic-driver in-ear with a compact metal shell, and the ceiling of its frequency extension sits below a larger open-back headphone or a dedicated IEM. Owners who listen exclusively to sub-bass-heavy electronic music will find the low end present but not expansive, and the midrange forwardness can make very dense mixes feel slightly congested.
What Customers Are Saying
The aggregate 4.1-out-of-5 rating across 1,033 reviews leans positive. Owners consistently call out the mid- and treble clarity, the usefulness of the in-line volume and track controls, and the fact that the all-metal construction feels substantially sturdier than a typical plastic earbud. Running users, commuters, and office workers who need a reliable set for calls and background music report satisfaction after months of daily use. The five tip sizes give a wide range of canal fits, and the carrying pouch is a small but appreciated inclusion.
The most recurring negative theme is the in-line control buttons. Multiple owners report that the pause and skip buttons do not register on their phones, forcing them to pocket the earbuds and operate the device by hand. A separate cluster of reviews describes static crackle or momentary audio cut-off when turning the volume dial, and one buyer received a replacement unit that exhibited the same fault. Durability is the second complaint: at least one owner found the set starting to fall apart after a few months of casual use, though others report four to five months of active running without issue.
A smaller but consistent note concerns fit and volume symmetry. The metal weight makes the buds crawl outward, and one or two owners arrived with a right-side bud running at noticeably lower volume than the left. None of these issues appeared universal; the majority of long-term owners report a stable, leak-free experience once the correct tip size is found.

Verdict
The M2 is the earbud you reach for when you want a wired set that will not snap after two weeks, that has a volume dial on the wire, and that keeps your voice clean on phone calls without a separate headset. The listener profile it serves is the commuter, the office worker on back-to-back conference calls, the casual gamer who needs squad comms through a 3.5mm port, and the runner who wants a cord that will not tangle in a jacket pocket.
If your priority is a flat, reference-grade frequency response or deep sub-bass extension, the M2 will not get you there. Its dynamic driver and compact metal shell set a ceiling below dedicated IEMs or over-ear cans, and the forward midrange can feel congested in very dense mixes. For the everyday use case the M2 is built around, the all-metal build, the five-tip fit system, and the clarity in the voice band make it a dependable wired option in its class.

FAQ
Do the in-line buttons work with a desktop PC or a Kindle?
No. The M2’s 3.5mm plug carries audio to any 3.5mm device, but the in-line control function is not recognized on older iPods, desktop PCs, laptops, or Kindle tablets. You get playback and a working microphone on those platforms, but the play/pause, skip, and volume buttons will not respond.
How do I get the bass to actually register on the M2?
Bass presence is tied directly to seal quality. Cycle through all five tip sizes and find the one, often the triple-flange, that fully occludes the canal without pain. Once the seal is airtight, the dynamic driver’s low-end boost becomes audible. A loose or mismatched tip lets the bass energy leak out and the set will sound thin.

Will the metal housing make the buds too heavy for running or long sessions?
The aluminum shell adds noticeable weight compared with plastic earbuds, and two owners note the buds slowly migrate outward during extended wear. For running, the same owners report that after the initial settling period the weight is manageable, and the 140cm cord stays clear of the chest and legs. The triple-flange tips help lock the shell in place against that outward pull.
Does the M2 need a Lightning adapter on an iPhone 7 or later?
Yes. The M2 terminates in a 3.5mm plug. iPhones from the 7 onward dropped the 3.5mm jack, so you will need an Apple Lightning-to-3.5mm adapter to connect. The in-line remote and microphone function through the adapter on iOS, and the same applies to any 3.5mm adapter for a USB-C phone.
