If you want serious passive noise isolation and wired, latency-free monitoring for stage or studio work, choose BASN Metalen 4; if you need true wireless freedom, long battery life and a sweat-resistant fit for daily life and workouts, choose Skullcandy Mod XT. Both lean on isolating designs rather than active noise cancellation, but they solve completely different problems.
• BASN Metalen 4 — biggest strength: four hybrid drivers (2 balanced armature + 2 dynamic) per earbud with a metal, CNC-crafted shell and two detachable MMCX cables, built for musicians who need detail and isolation on a wired connection.
• BASN Metalen 4 — biggest trade-off: it's wired and has no Bluetooth, no app and no water-resistance rating, so it's a poor fit for the gym or for people who hate cables.
• Skullcandy Mod XT — biggest strength: up to 34 hours of total battery life (7 in the buds, 27 in the USB-C case), Bluetooth 5.2, multipoint pairing and an IP55 rating, plus a noise-isolating fit that blocks background sound passively.
• Skullcandy Mod XT — biggest trade-off: it's a consumer true-wireless set, so it won't match the driver count, detachable-cable serviceability or reference-style tuning of a dedicated in-ear monitor.
• Who each pick is for: BASN Metalen 4 is for singers, drummers, bassists and anyone who wants wired, isolating IEMs; Skullcandy Mod XT is for commuters, call-takers and gym-goers who want wireless convenience.
The BASN Metalen 4 is a purpose-built in-ear monitor. Each earbud packs four drivers — two balanced armature and two dynamic — which is a hybrid setup designed to split the workload: the dynamic drivers handle low-end punch and the balanced armatures handle detail and definition. The result, on paper, is a frequency range of 16 Hz to 25,000 Hz with 108 dB sensitivity and 16 ohm impedance. That low impedance matters, because it means the Metalen 4 is easy to drive straight from a phone, a small mixer or a headphone amp without needing a lot of power.
The isolation story here is passive, not electronic. The Metalen 4 uses a rounded-tip, in-ear design with S, M and L silicone tips plus memory foam tips in the box. That's the classic musician's approach to blocking noise: get a deep, sealed fit so outside sound never reaches your ear in the first place. For a drummer sitting next to a loud kit or a bassist standing near an amp, a good seal is what keeps you from cranking the volume and damaging your hearing. The metal, CNC-machined and electroplated housing is also a practical detail — it resists wear and corrosion, which matters if you're tossing these in a gig bag night after night.
What you're buying, beyond sound, is a kit. BASN includes two detachable MMCX cables — one silver-plated OFC cable without a mic and one fiber cable with an inline mic and volume control — plus a T-shirt clip, three sizes of tips, memory foams, velcro strips, a cleaning brush, a 1/4" adapter and a carrying case, all backed by a 12-month warranty. The MMCX detachable design is the quiet hero: if a cable fails, you replace the cable, not the whole earphone.
Skullcandy Mod XT: Who It's For
The Skullcandy Mod XT is the opposite philosophy. It's a true-wireless pair with Bluetooth 5.2, and it's built around convenience. Battery life is the headline: up to 7 hours in the earbuds plus another 27 in the USB-C charging case, for up to 34 hours total. Rapid Charge tops you up with about 2 hours of playback from a 10-minute charge, which is the kind of thing that saves you on the way out the door.
Noise isolation on the Mod XT is also passive — the product is described as having a noise-isolating fit that blocks unwanted noise, and each bud uses a Clear Voice Smart Mic with dual noise-reducing microphones to keep your voice clear on calls and video meetings. So when you're on a noisy street or in a shared office, the seal in your ear does the blocking and the mic array does the cleanup on your end of the call. If you want to let the world back in, there's Stay-Aware Mode through the Skullcandy App, which pipes in surrounding sound without you removing the buds.
The extras are what make it a daily driver. Multipoint pairing connects two Bluetooth devices at once, so you can jump from a laptop call to phone audio without re-pairing. The Skullcandy App lets you adjust EQ presets and remap the button controls. And the IP55 rating means sweat, water and dust resistance — a genuine advantage if you run, lift or commute in bad weather.
Who should buy it: commuters, remote workers who live on calls, gym-goers, and anyone who wants one pair of earbuds for everything and never wants to think about a cable. Who should skip it: musicians who need wired, latency-free monitoring, and buyers who want a replaceable cable or a metal, serviceable housing — none of that exists on a sealed true-wireless design like this.
Side-by-Side: Which Should You Choose?
• Best for stage and studio monitoring → BASN Metalen 4. Wired 3.5 mm connection with no Bluetooth latency, and detachable MMCX cables you can swap or replace.
• Best for blocking noise passively → a tie, with a caveat. Both rely on a sealing, noise-isolating fit rather than active noise cancellation. The Metalen 4's memory-foam tips give you more ways to dial in that seal; the Mod XT pairs its fit with noise-reducing mics for calls.
• Best for calls and meetings → Skullcandy Mod XT. Dual noise-reducing microphones and multipoint pairing across two devices are built for exactly this.
• Best for workouts and weather → Skullcandy Mod XT. IP55 sweat, water and dust resistance; the Metalen 4 carries no such rating.
• Best for sound-shaping control → Skullcandy Mod XT. App-based EQ presets and remappable buttons.
• Best for durability of the housing and repairability → BASN Metalen 4. CNC metal shells with electroplated corrosion resistance, and a cable you can replace instead of the whole unit.
• Best for a complete musician's kit out of the box → BASN Metalen 4. Two cables, three tip sizes, memory foams, clip, cleaning brush, 1/4" adapter, case and a 12-month warranty.
In my opinion, the right buy comes down to one question: do you need a cable or not? If you play an instrument, sing, or monitor live sound, I'd buy the BASN Metalen 4 — the four-driver hybrid setup, the 16 ohm easy-to-drive impedance and the replaceable MMCX cables are exactly what that job needs, and the passive isolation from a proper foam-tip seal is the real deal for loud environments.
If your day is commutes, calls and workouts, I'd buy the Skullcandy Mod XT instead. The 34-hour battery, IP55 rating and multipoint Bluetooth make it the more useful object in ordinary life. Check the current price on Amazon before you commit, since both sit in very different value brackets.
how to noise cancelling headphones work
Active noise cancelling headphones use microphones to sample outside sound and then play an inverted sound wave to cancel it out. Neither product here does that — both BASN Metalen 4 and Skullcandy Mod XT rely on passive noise isolation, meaning a tight in-ear seal physically blocks sound from reaching your ear. That's why fit matters so much on both.
how to use noise cancelling headphones
With an isolating design like these, the "use" is mostly about the seal. Insert the tip so it sits snugly in your ear canal — the Metalen 4 gives you S, M and L silicone tips plus memory foams to find that fit, while the Mod XT relies on its noise-isolating shape. A good seal is what actually blocks the noise; a loose one defeats the purpose.
how to test noise cancelling headphones
Put them in, get a proper seal, and compare how much surrounding sound drops with them in versus out — a fan, traffic, or a conversation is a good reference. On the Mod XT you can also toggle Stay-Aware Mode in the Skullcandy App to hear the difference between blocked and piped-in sound. On the Metalen 4, just try different tip sizes and foams to hear how much the seal changes.
No. The BASN Metalen 4 lists sound isolation as its noise control, and the Skullcandy Mod XT is described as having a noise-isolating fit. Both reduce noise by sealing your ear, not by generating anti-noise. The Mod XT does add dual noise-reducing microphones, but those work on your voice during calls, not on what you hear.
