If you want a wired in-ear monitor with a flat, neutral tuning that stays put during a workout, choose BASN MTPro 14.5mm; if you need an over-ear, studio-style headphone with a big dynamic driver and a DJ-ready cable setup, choose Linsoul Kiwi Ears Division. That's the short version. The longer version comes down to one thing: how much you care about a flat frequency response and whether you want something that lives in your ears or on your head.
• BASN MTPro 14.5mm — biggest strength: a 14.5mm planar magnetic driver with a double-sided magnetic array, tuned toward a fairly neutral, balanced signature. That planar design is the reason this pair shows up in flat-frequency-response conversations.
• BASN MTPro 14.5mm — biggest trade-off: it's a wired MMCX in-ear, so there's no true wireless freedom — the "Bluetooth" listing refers to the bundled mic cable pairing with phones, not a standalone wireless mode.
• Linsoul Kiwi Ears Division — biggest strength: a 40mm composite dynamic driver tuned for classic monitoring duty, with punchy bass, a neutral midrange and clean treble, plus dual 3.5mm-to-6.35mm adapters for studio gear.
• Linsoul Kiwi Ears Division — biggest trade-off: it's an over-ear design with passive noise cancellation, so isolation depends on the plush vegan-leather earcups rather than a deep in-ear seal, and it's bulkier to carry.
• Who each pick is for: BASN MTPro for the listener who wants a neutral in-ear that disappears during movement; Kiwi Ears Division for the musician, engineer or DJ who wants a full-size monitoring headphone.
The MTPro is built around a 14.5mm planar diaphragm driver, and that choice shapes everything else about it. A planar driver moves a thin diaphragm across a wide, even surface, and BASN pairs it with a double-sided magnetic array. In plain terms, that's a recipe for detail and control rather than thump. The 20Hz–20,000Hz range, 32-ohm impedance and 102dB sensitivity put it in comfortable territory for phones, dongles and in-ear monitoring systems alike.
Buy it if you want a wired IEM with a neutral-leaning, easy-to-listen-to signature and you'd rather have your music sealed into your ears than sitting on top of them. Skip it if you want a genuinely wireless experience or you dislike cables catching on gym equipment. Also skip it if you want a bass-forward, club-style tuning — the MTPro's honest, balanced presentation is the point, not a side effect.
Linsoul Kiwi Ears Division: Who It's For
The Division is the opposite philosophy in almost every way. It's an over-ear headphone built from the ground up for monitoring and DJ work, and Linsoul leans hard into that heritage. The 40mm composite diaphragm dynamic driver is a classic design, with diaphragm tension adjusted across many iterations and an upgraded voice coil and magnet assembly for responsiveness. The tuning is deliberately old-school studio: strong bass impact with quick decay, a neutral midrange for accurate instruments and vocals, and detailed treble that stays clear without turning harsh.
Physically, it's a lightweight over-ear with vegan-leather earcups and a plush vegan-leather headband, finished in black (a pink scheme also exists). Impedance is 32 ohms and sensitivity is 98dB, with a 20Hz–20KHz range. The cable terminates in dual 3.5mm-to-6.35mm adapters, which is exactly what you want if you're plugging into a mixer, interface or amp. Noise control is passive, handled by the earcup seal rather than electronics, and the control method is touch.
Buy it if you're a DJ, engineer, producer or a committed enthusiast who wants one headphone that can handle a session and then a commute. The bass decay is tuned for precision, which matters when you're beat-matching or checking a mix. Skip it if you need maximum isolation on a noisy train, if you want in-ear discretion, or if you want a flat reference rather than an engaging, slightly bass-forward monitoring signature.
• Best for workout → BASN MTPro 14.5mm. A sealed in-ear with 12 pairs of eartips beats a full-size over-ear for keeping sound in and distractions out while you move.
• Best for flat frequency response → BASN MTPro 14.5mm. In my opinion, the planar driver's neutral, balanced character is the closer thing to a reference-flat presentation here.
• Best for studio and DJ work → Linsoul Kiwi Ears Division. The 40mm dynamic driver and 6.35mm adapters are built for desks, decks and interfaces.
• Best for cable flexibility → BASN MTPro 14.5mm. Two detachable MMCX cables and a swappable connector give you more ways to route your setup.
• Best for long listening sessions → Linsoul Kiwi Ears Division. Over-ear vegan-leather earcups rest on the head rather than inside the ear canal.
• Best for commuting and travel → Linsoul Kiwi Ears Division. Lightweight, over-ear, and no cable snagging on your ears when you turn your head.
• Best for phone calls → BASN MTPro 14.5mm. The bundled mic cable adds inline volume and playback control.
• Best for anyone who hates cables → neither. Both are wired designs; this comparison is for listeners who value the connection quality that comes with a cable.
I'd buy the BASN MTPro 14.5mm — but specifically if the workout use case is real for me. The 14.5mm planar driver gives you the flatter, more neutral response this whole comparison is about, the 12 pairs of eartips let you dial in a seal that survives movement, and the two MMCX cables mean you can switch between listening and calls without buying anything else. In my opinion the Kiwi Ears Division is the better tool for a studio desk or a DJ booth, and the 40mm dynamic driver is genuinely well suited to that job.
If you're shopping for bluetooth headphones for workout, be honest with yourself: neither of these is a wireless set. What you're choosing between here is a neutral wired IEM and a monitoring over-ear. Check the current price on Amazon for both and let your actual use decide.
FAQ
Yes, and it's the single biggest factor in how a headphone sounds. Both of these cover 20Hz–20KHz, so the range is identical — what differs is how each is tuned within it. The MTPro leans neutral and balanced; the Division leans toward strong bass impact, a neutral midrange and clear treble.
are these good for a workout
The BASN MTPro 14.5mm is the more sensible choice for training. Its ergonomic in-ear shape is designed to reduce outside noise, and the 12 pairs of included eartips help you find a fit that stays put. The Kiwi Ears Division is a full-size over-ear, so it's better suited to desk and studio sessions than to the gym floor.
do I need an amp to drive either one
Probably not. Both are rated at 32 ohms, and the MTPro is the more sensitive of the two at 102dB versus 98dB for the Division. A phone or laptop should handle either, though the Division's 6.35mm adapters make it easy to plug into proper studio gear when you have it.
what's in the box for each
The MTPro ships with a pair of earbuds, two detachable MMCX cables (one with an inline mic), 12 pairs of replacement eartips, a storage case, a 1/4-inch adapter, a cable clip and a cleaning tool. The Division ships with its cable and the dual 3.5mm-to-6.35mm adapters, in a simple box or bag.
