• BASN Metalen 4 — biggest strength: four hybrid drivers per earbud (2 balanced armature + 2 dynamic) inside a CNC aluminum alloy shell, with both silicone and memory foam tips for a deeper noise-isolating seal.
• BASN Metalen 4 — biggest trade-off: it's a wired, music-first IEM with a detachable MMCX system, so you're carrying a cable and you'll want to keep track of the two included cables.
• Aitalk Versatile — biggest strength: a 10mm dynamic driver with dual-magnet, dual-chamber tuning, a built-in mic and inline remote, and a 4 ft cord that plugs straight into a PC, laptop, Xbox, PS5 or Switch.
• Aitalk Versatile — biggest trade-off: one dynamic driver and a plastic housing mean less driver separation and a lighter build than the metal BASN shell.
• Pick BASN Metalen 4 if you're a musician, drummer or bassist who wants maximum isolation and detail on stage or in the studio.
• Pick Aitalk Versatile if you're a gamer or all-day listener who wants one cable with a mic, volume control and console-friendly plug-and-play.
The Metalen 4 is the more ambitious design of the two. Each earbud packs four drivers — two balanced armature and two dynamic — and BASN tunes that combination for definition, detail and a stronger bass response while keeping the frequency range balanced from 20 Hz to 20,000 Hz. If you play drums or bass, that hybrid setup is the reason to look here: dynamic drivers move air for the low end, balanced armatures handle the fine detail up top, and you get both in one shell.
The housing is the other half of the story. It's carved from CNC aluminum alloy and finished with a hard oxidation treatment, so the metal has a real texture rather than a painted-on look. Metal shells like this do two useful things — they feel substantial in the ear and they help block outside noise passively. Combined with the ergonomic rounded-tip shape and the included silicone and foam eartips, you get genuine sound isolation rather than electronic trickery. Foam tips in particular expand to fill the canal, which is exactly what you want when a stage monitor or a loud room is fighting your mix.
Then there's the MMCX detachable connector. BASN ships two cables — one for straight IEM use and one with volume control and music playback — and you can swap in any other MMCX cable later. For a working musician this matters: cables are the first thing to fail, and a detachable system means the earphones outlive the cable.
Aitalk Versatile: Who It's For
The Aitalk Versatile goes a different route entirely. It uses a single 10mm dynamic driver with a composite resin diaphragm, paired with dual-magnet, dual-chamber technology. Aitalk also adds acoustic damping foam and a precision tuning mesh inside, which optimizes airflow and smooths out harsh treble while keeping the bass tight and the vocals clear. In plain terms: one well-tuned driver, done carefully, rather than four drivers juggled together. With 22 ohm impedance and 95 dB sensitivity, it's easy to drive from a phone, controller or laptop headphone jack.
Where it clearly pulls ahead is convenience. There's a built-in mic and an inline remote, so you can take calls, change volume, control playback and even trigger a voice assistant without touching your phone. For gaming that's the whole point — you can talk to teammates, adjust volume mid-match and switch between music and chat without unplugging anything. The 4 ft cord and 3.5mm jack are explicitly aimed at PC, laptop, Xbox, PS5 and Switch, so it's a plug-in-and-go setup on hardware that uses a standard analog jack.
Comfort is the other focus. The over-ear cable hooks keep the buds locked in place during movement, and Aitalk includes three sizes of soft silicone tips (S, M, L) to create a noise-isolating seal that fits your ears specifically. That seal is what does the actual noise blocking here — there's no active circuitry involved, just a good fit.
Buy it if: you game on console or PC, take calls while listening, and want a lightweight IEM that stays comfortable for hours. Skip it if: you need the detail and driver separation of a multi-driver monitor, or you prefer a metal shell and a swappable cable system.
Side-by-Side: Which Should You Choose?
• Best for maximum noise isolation → BASN Metalen 4. Silicone and foam eartips plus a solid metal shell that blocks external sound passively.
• Best for driver detail and separation → BASN Metalen 4. Four hybrid drivers per earbud versus one dynamic driver.
• Best for long, fatigue-free sessions → Aitalk Versatile. Lightweight plastic build, over-ear hooks and three tip sizes for a pressure-free fit.
• Best for musicians and stage monitoring → BASN Metalen 4. Detachable MMCX connector, two included cables and a metal build meant for working players.
• Best for plug-and-play across devices → Aitalk Versatile. A 3.5mm jack that Aitalk lists for phones, laptops, tablets, desktops, PCs, MP3 players and PS5/PS4, Switch and Xbox.
• Best for tinkering and customization → BASN Metalen 4. Swap MMCX cables to change the look or replace a worn cable.
• Best for easy driving from weak sources → Aitalk Versatile. 22 ohm impedance and 95 dB sensitivity are undemanding loads.
If I had to pick one, I'd buy the BASN Metalen 4. My reasoning is simple: it does the harder job. The quad hybrid driver array, the CNC aluminum shell and the foam-tip seal all push toward one goal — keeping outside noise out and detail in — and that's the thing you can't fake with a spec sheet alone. In my opinion it's the better pick for anyone who treats their earphones as a tool for music, monitoring or practice.
That said, the Aitalk Versatile wins on everyday practicality. If your day is split between gaming, calls and casual listening, the mic, remote and console-ready cord make it the more convenient choice. It's a genuinely different product for a genuinely different buyer.
how to noise cancelling headphones work
Strictly speaking, neither of these uses active noise cancellation — both are wired IEMs that rely on passive sound isolation. The seal formed by the eartip blocks outside noise before it reaches your ear. The BASN Metalen 4 supports this with both silicone and foam tips plus a metal shell, while the Aitalk Versatile uses soft silicone tips in three sizes to create a secure, noise-isolating seal.
how to use noise cancelling headphones
Insert the tip deep enough to seal the ear canal, then choose the right tip size — the Aitalk Versatile includes S, M and L silicone tips, and the BASN Metalen 4 includes silicone and foam options. A proper seal is what delivers the isolation, so if outside noise leaks in, try a different tip. On the Aitalk you then control volume and playback with the inline remote; on the BASN you can use the included cable with volume control.

Play something quiet and listen for how much of the room disappears — that tells you how well the seal is working. Then try each included tip size and material to find the best fit. The Aitalk Versatile gives you three silicone sizes to compare, while the BASN Metalen 4 lets you compare silicone against foam, which usually isolates more.
The Aitalk Versatile is the more gaming-oriented of the two, with a built-in mic, inline volume control and a 3.5mm jack that Aitalk lists for PS5, PS4, Switch, Xbox, PC and laptop use. The BASN Metalen 4 is designed around in-ear monitoring for musicians, with a detachable MMCX connector, so it's better suited to music and stage work than to team chat.
