If you want a wired, sweatproof in-ear monitor you can also use for everyday listening, choose BASN Metalen 4; if you need a wireless system that lets you move around a stage or studio hands-free, choose Depusheng Ear Monitor System. Those two sentences decide it for most people. The rest of this article is me showing my work — because "dj monitor headphones" means two very different jobs depending on whether you're the one behind the decks or the one roaming the room.
• BASN Metalen 4 — biggest strength: four hybrid drivers per earbud (2 balanced armature + 2 dynamic), a 16 Hz–25 kHz range, and two detachable MMCX cables, one of them with an inline mic. That's a lot of hardware for wired monitoring and casual listening in one package.
• BASN Metalen 4 — biggest trade-off: it's wired. You're tethered to whatever you plug into, and there's no wireless freedom anywhere in the spec sheet.
• Depusheng Ear Monitor System — biggest strength: a true wireless RF system with zero-latency monitoring, a built-in condenser mic for pickup, and over 50 meters of transmission distance.
• Depusheng Ear Monitor System — biggest trade-off: it's a monitoring system, not a music-listening pair. Single dynamic driver, 20 Hz–20 kHz, and you're relying on the receiver's battery (8 hours, 2 hours to charge).
• For whom: BASN Metalen 4 suits drummers, bassists, singers and DJs who want isolation and deep bass on a cable; Depusheng suits performers and presenters who need to move, listen to their own voice in real time, and skip the cable.
The BASN Metalen 4 is built around driver count. Each earbud packs two balanced armature drivers and two dynamic drivers — four per side. In practice that means the design splits the work: armatures handle detail and articulation, dynamics push the low end. The spec sheet lists a 16 Hz–25 kHz frequency range, 32 ohm impedance and 108 dB sensitivity, which tells you it's meant to be driven by ordinary gear — a phone, a mixer output, a headphone amp — without demanding anything exotic.
What makes it interesting for DJ and stage use is the cable situation. You get two 4.9 ft cables: a silver-plated OFC cable without a mic, and a fiber cable with an inline mic and media/volume/call controls. The MMCX connector rotates and is replaceable, so if a cable dies you swap it instead of the whole set. The housing is CNC-milled metal with a gray matte finish and the design is described as sweatproof, which matters on a hot stage. You also get memory foam tips, three sizes of silicone tips, a 1/4" adaptor, a T-shirt clip and a carrying case — the 1/4" adaptor in particular is the tell that this is aimed at people plugging into pro gear.
Who should buy it: drummers, bassists, singers, guitarists and DJs who want strong isolation, deep bass and detail, and who are fine being wired. Also anyone who wants one pair that works for monitoring and normal listening, since the mic cable turns it into a regular headset. Who should skip it: anyone who needs to walk a stage or a room untethered, or who wants the simplest possible setup. Wired means wired.
The Depusheng is a different animal entirely — it's a system, not just earbuds. You get a transmitter and a clip-on receiver, and pairing is a one-button affair that completes in seconds. It runs on RF wireless, supports one-to-multiple setups, and the spec sheet claims over 50 meters of transmission distance. For anyone who has ever tripped over a cable mid-set, that number is the whole pitch.
The headline feature is zero-latency monitoring with what's described as ultra-low latency technology, so you hear your own voice or instrument essentially in real time. That's the thing wireless IEMs live or die on — a delay you can perceive throws off your timing. It also has a built-in high-sensitivity condenser mic to capture instrument sound, which is unusual for an IEM and suggests it's meant for pickup as well as playback.
On the audio side it's more modest: a single dynamic driver, 21.8 ohm impedance, 105 dB sensitivity, 20 Hz–20 kHz. Environmental noise cancellation is listed rather than the passive isolation of a sealed metal shell. The receiver battery is good for over 8 hours on a 2-hour charge. The earpieces are ergonomic in-ears designed for long wear without fatigue — a real consideration when you're wearing them for a full rehearsal or set.
Who should buy it: performers, presenters, guitarists and DJs who need freedom of movement, real-time self-monitoring, and a quick setup. Anyone running a multi-person monitoring setup benefits from the one-to-multiple support. Who should skip it: critical listeners chasing maximum detail and bass extension, and anyone who'd rather not manage a battery and a transmitter. It's a tool for performing, not a hi-fi listen.
Side-by-Side: Which Should You Choose?
• Best for freedom of movement → Depusheng Ear Monitor System. RF wireless with over 50 meters of range beats any cable.
• Best for zero-latency self-monitoring → Depusheng. That's its core design goal.
• Best for plug-and-play with existing gear → BASN Metalen 4. 3.5 mm jack, 32 ohm, 108 dB sensitivity, plus a 1/4" adaptor in the box.
• Best for long sessions without charging → BASN Metalen 4. No battery to manage at all; the Depusheng gives you 8 hours per 2-hour charge.
• Best for one-to-multiple monitoring setups → Depusheng. Explicitly supported; the BASN is a single-listener wired pair.
• Best for durability against sweat and wear → BASN Metalen 4. CNC metal housing described as sweatproof, with replaceable MMCX cables.
• Best for simplicity → Depusheng. Turn on, press one button, paired. No cables to route.
If you're a DJ deciding between them: the BASN is the pair you'd also happily use to preview tracks and listen casually, while the Depusheng is the system you'd wear when you need to move and hear yourself clearly. Different jobs, honestly.
If I had to pick one for a wired, do-it-all monitor that doubles as a normal headset, I'd buy the BASN Metalen 4. In my opinion the four-driver hybrid design, the metal sweatproof shell, the two swappable MMCX cables and the 1/4" adaptor make it the more versatile piece of gear for someone who monitors on a cable and also wants to just listen. I'd only steer you to the Depusheng Ear Monitor System if wireless freedom and real-time self-monitoring are non-negotiable — that's a need the BASN simply can't meet, and the Depusheng meets it well. Check the current price on Amazon before you commit, since that's the one thing specs can't tell you.
FAQ
what is studio monitor headphones
why do djs wear headphones
DJs wear headphones to cue the next track privately while the main system plays, and to hear their own mix over loud room noise. That's why isolation matters — the BASN Metalen 4 uses sound isolation with memory foam and silicone tips, while the Depusheng lists environmental noise cancellation for its wireless in-ears.
why djs wear headphones
Same reason as above: cueing and monitoring. If you're wired to the mixer, a low-impedance, high-sensitivity pair like the BASN Metalen 4 (32 ohm, 108 dB) is easy to drive. If you need to step away from the booth, the Depusheng's RF wireless and 50-meter range is the practical answer.
why do djs need headphones
Because you can't mix what you can't hear. You need either accurate isolation on a cable or reliable low-latency wireless monitoring — and those are exactly the two paths these products take. Pick based on whether you're standing at the deck or moving around the room.
