• Linsoul ZiiGaat x Hangout — biggest strength: a complete portable reference chain in one purchase: the ZiiGaat Odyssey 2 hybrid in-ear monitor (1DD + 3BA) plus the Kiwi Ears Allegro Mini IEM DAC/amplifier in an aluminum alloy body.
• Linsoul ZiiGaat x Hangout — biggest trade-off: it's an in-ear design, so the "monitor" experience is canal-fit dependent, not a padded over-ear fit, and it's aimed at adult listeners who want portability over a big studio headband.
• Sony MDR-M1 — biggest strength: purpose-built closed-back studio monitor headphones with ultra-wideband playback, a 5Hz–80kHz frequency response, and a fit designed for long mixing sessions.
• Sony MDR-M1 — biggest trade-off: it's a wired on-ear headphone with no water resistance and no inline amplification included — you supply your own interface, amp or adapter.
• Who each pick is for: Linsoul ZiiGaat x Hangout for the mobile creator, IEM listener or traveler who wants a reference-oriented in-ear rig that travels light; Sony MDR-M1 for the producer, mixer or editor who wants over-ear monitor headphones for critical listening at a desk.
The Linsoul ZiiGaat x Hangout is really two products working as one system. The ZiiGaat Odyssey 2 is a hybrid in-ear monitor built around a 1DD + 3BA driver configuration — a dynamic driver plus three balanced armatures — and it's the result of a collaboration between ZiiGaat and Hangout.Audio that updates the original Odyssey with newer drivers and a revised tuning platform. In plain terms, the design intent is deeper bass extension, a more balanced tonal signature, and a smoother overall listening experience than a single-driver earphone typically manages. The hybrid approach is what makes that possible: dynamic drivers tend to handle low-end weight, while balanced armatures handle detail and separation up top.
The second half of the package is the Kiwi Ears Allegro Mini, a portable IEM DAC and amplifier. It follows the same high-fidelity philosophy as the full-size Allegro but shrinks it down, and the housing is an all-aluminum alloy body — which matters on a device that lives in a pocket or a bag, because it resists the flex and rattle that cheap plastic shells pick up over time. The enclosure material on the Odyssey 2 itself is also aluminum.
Sony MDR-M1: Who It's For
The Sony MDR-M1 sits in a different category entirely: closed monitor headphones, on-ear, wired, black, and explicitly described as studio monitor headphones for accurate sound. The headline number is the frequency response — 5Hz to 80kHz — paired with ultra-wideband playback and high-resolution capability. That's an unusually wide window, and the practical payoff is headroom: high-resolution audio formats have content well above the range of human hearing, and a driver that can reproduce that band tends to behave more linearly in the audible range below it. Whether you can "hear" 80kHz is the wrong question. The point is that the driver isn't straining at the edges of what you actually hear.
The acoustic design is closed-back with sound isolation as a stated goal, which is the classic configuration for a reference monitor you use while recording or while working in a room that isn't perfectly quiet. Sony also calls out a comfortable fit for long mixing sessions — a real consideration, because monitor headphones live on your head for hours, and an on-ear clamp that's too tight becomes unusable by hour three.
The bundle includes a 27-month Axiom care extension on top of the original factory warranty, plus a user manual. It's a single-item package: one pair of headphones, no amp, no DAC, no case mentioned in the specs. It's listed as compatible with cellphones and includes volume control and a lightweight build, with a folding on-ear design. Water resistance is explicitly "not water resistant" — worth knowing before you toss it in a gig bag next to a water bottle.
Buy it if you're a producer, mixing engineer, podcast editor, or content creator who works at a desk and wants over-ear monitor headphones for critical listening and long sessions. Skip it if you need wireless, if you need water resistance, or if you want the amplification handled for you out of the box.
• Best for mobile/portable reference listening → Linsoul ZiiGaat x Hangout. The in-ear form factor plus the Allegro Mini DAC/amp makes it a self-contained travel rig.
• Best for long desk sessions → Sony MDR-M1. Sony explicitly designs the fit for extended mixing sessions, and an on-ear headphone doesn't cause the canal fatigue an IEM can after hours.
• Best for driver curiosity and hybrid tuning → Linsoul ZiiGaat x Hangout. A 1DD + 3BA hybrid configuration with a revised tuning platform is the more interesting technical story if you like to hear how different driver types divide the work.
• Best for widest measured frequency range → Sony MDR-M1. The 5Hz–80kHz figure with ultra-wideband playback is the number to look at for high-resolution source material.
• Best for recording and isolation work → Sony MDR-M1. A closed acoustic structure with sound isolation is built for tracking and for rooms that aren't acoustically treated.
• Best for plugging straight into a laptop or phone with no extra gear → Linsoul ZiiGaat x Hangout. The included DAC/amp means you're not hunting for an interface before you can listen.
• Best for a warranty cushion → Sony MDR-M1. The 27-month Axiom care extension adds coverage beyond the standard factory warranty.
• Best for aluminum-bodied durability in a pocket-sized setup → Linsoul ZiiGaat x Hangout. Both the IEM and the Allegro Mini use aluminum alloy enclosures.
In my opinion, the right pick comes down to one question: do you monitor at a desk or on the move? If your work happens at a desk — mixing, editing, tracking, critical listening against high-resolution files — I'd buy the Sony MDR-M1. The 5Hz–80kHz response, the closed isolating structure, and the fit built for long mixing sessions are exactly the traits a reference monitor should have, and the extended care coverage is a genuine bonus.
If your work happens anywhere else — a train, a café, a hotel room, a laptop on a couch — I'd buy the Linsoul ZiiGaat x Hangout. Getting a hybrid 1DD + 3BA in-ear monitor and a compact aluminum DAC/amp in one box means fewer things to carry and fewer things to forget. Both are legitimate reference tools. They just live in different places.
Reference studio headphones are headphones designed to reproduce sound accurately and neutrally rather than to flatter it with boosted bass or treble. The idea is that what you hear matches what's actually in the recording, so your mix decisions translate to other systems. The Sony MDR-M1 fits this description directly — Sony describes it as studio monitor headphones for accurate sound with a wide frequency response for critical listening.
What are studio monitor headphones?
Studio monitor headphones are the headphone equivalent of studio monitor speakers: a monitoring tool for recording, mixing and editing rather than casual listening. They typically emphasize accuracy, isolation and comfort over long sessions. The MDR-M1 uses a closed acoustic structure with sound isolation and a fit Sony designed for long mixing sessions — the classic monitor-headphone brief.
The distinction is form factor and use case. Over-ear studio monitor headphones like the Sony MDR-M1 sit around your ears with a headband and give you a stable, repeatable fit for hours at a desk. In-ear monitors like the ZiiGaat Odyssey 2 in the Linsoul bundle seal inside your ear canal, which makes them far more portable and easier to use on the move — but the fit depends on your ears, and long sessions can feel different.
Yes, but "monitor" can mean two things. If you mean a computer monitor or a display, many have a headphone jack you can plug into. If you mean a studio monitor setup, you normally connect headphones to an audio interface, mixer or headphone amp rather than to the speakers themselves. The Linsoul bundle sidesteps this by including the Kiwi Ears Allegro Mini DAC/amp, so the Odyssey 2 has its amplification built into the package; the Sony MDR-M1 is wired and expects you to supply the source and any amplification you want.
One practical note before you decide: I don't quote prices here because they move around, and both of these are sold as bundles with different contents — the Linsoul package pairs an IEM with a DAC/amp, while the Sony package pairs the headphone with an extended care plan. Check the current price on Amazon for each and compare what's actually in the box, because that's what determines the real value for your setup.
