• Focusrite Scarlett Solo 4th — biggest strength: A purpose-built recording front end with a 1 XLR mic preamp, a Hi-Z instrument input, 24-bit/192kHz converters, 120dB dynamic range, and a custom headphone amp explicitly designed to drive high impedance headphones louder and clearer.
• Focusrite Scarlett Solo 4th — biggest trade-off: It's a desk-bound, USB-powered interface with no wireless mode and no battery, so it isn't a portable listening device and it won't isolate you from job-site noise.
• Linsoul ZiiGaat x Fresh — biggest strength: A 1DD+4BA hybrid in-ear monitor with a 10mm subwoofer-style dynamic driver, four balanced armatures, a full CNC aluminum shell, and a detachable silver-plated OFC cable — a tuning-first design with a 20Hz–40kHz range.
• Linsoul ZiiGaat x Fresh — biggest trade-off: It's a wired 3.5mm IEM with noise control: None, so it does not actively cancel sound, and its 24 ohm impedance is easy to drive but not aimed at the high impedance headphone question at all.
• Who each pick is for: Choose the Scarlett Solo 4th if you're recording vocals or guitar and want to drive high impedance studio headphones properly. Choose the ZiiGaat x Fresh if you want detailed wired in-ears for listening and monitoring.
The Scarlett Solo 4th is, at its core, a songwriter's interface. You get one XLR mic preamp and one Hi-Z instrument input, so the workflow is simple: plug in a mic, plug in a guitar, and record. That's the whole pitch, and it's an honest one. The Hi-Z input is designed to feel like an amp when you plug a guitar straight in, and the mic pre is built to sound right immediately rather than after an hour of tweaking.
Where this unit earns its place is the conversion and monitoring chain. The 24-bit/192kHz converters and 120dB dynamic range come from the same converter family Focusrite uses in its flagship interfaces, and the improved Air mode lifts vocals and guitars forward in the mix with added harmonic character. In my opinion, the detail that matters most for this comparison is the custom-designed headphone amp: Focusrite states it drives high impedance headphones louder and clearer than before. If you own a pair of high impedance studio headphones, that's the spec to care about, because plenty of small interfaces simply run out of clean gain with those loads. The Dynamic Gain Halos also make level-setting visual and quick.
Linsoul ZiiGaat x Fresh: Who It's For
The ZiiGaat x Fresh Arete II is a wired in-ear monitor built around a hybrid driver array: one dynamic driver plus four balanced armatures. The dynamic side is a 10mm liquid silicone suspension diaphragm with a stronger neodymium magnet array, tuned for subwoofer-like low end — deep rumble while keeping the punch articulate. The four balanced armatures handle the rest, with two Knowles ED 29689 drivers covering the midrange, a slightly boosted midrange for a lusher vocal and instrument texture, and a more precise crossover network smoothing the transitions between bass, low-mids, and treble.
The physical design is genuinely premium for this category. Each shell is CNC machined from solid aerospace-grade aluminum, then hardened and hand finished, with aluminum faceplates to match. That's a far cry from plastic housings — and worth noting, since the spec sheet's "enclosure material: Plastic" line sits oddly against the marketing's full-metal description, so I'd treat the metal construction claim as the design intent and the plastic field as a data inconsistency. The cable is a detachable 2-pin 0.78mm design made from silver-plated oxygen-free copper, which helps with noise-free signal transmission and also means you can replace the cable instead of the whole IEM when it wears out.
Who should buy it: musicians and audiophiles who want detailed wired in-ears with a bass-forward tuning, a replaceable cable, and a metal build that can take some abuse. The 3.5mm jack and wired-only connection mean it plugs into phones, laptops, and interfaces directly. Who should skip it: anyone who needs active noise cancellation. The spec is explicit — noise control: None — so these are passive IEMs, and whatever isolation you get comes only from the fit of the tips in your ears.
Side-by-Side: Which Should You Choose?
• Best for driving high impedance studio headphones → Focusrite Scarlett Solo 4th. Its headphone amp is specifically built to push high impedance loads louder and clearer.
• Best for detailed wired listening → Linsoul ZiiGaat x Fresh. A 1DD+4BA hybrid with a 20Hz–40kHz range and a subwoofer-tuned low end.
• Best for build durability in a pocket or bag → Linsoul ZiiGaat x Fresh. Full CNC aluminum shells and a detachable cable beat a desktop interface you can't carry.
• Best for a full recording software bundle → Focusrite Scarlett Solo 4th. Pro Tools Intro+, Ableton Live Lite, Cubase LE, and the Hitmaker Expansion are all included.
• Best for blocking out a noisy environment → Neither, strictly speaking. The Scarlett Solo has no isolation at all, and the ZiiGaat x Fresh lists noise control as None. If you specifically need noise canceling, look elsewhere.
• Best for a simple plug-and-play desk setup → Focusrite Scarlett Solo 4th. USB bus-powered, Mac/Windows/iPad compatible, no batteries or charging.
• Best for low-friction mobile use → Linsoul ZiiGaat x Fresh. A 3.5mm wired jack works with almost anything, and there's no software to install.
In my opinion, the Focusrite Scarlett Solo 4th is the better buy for most people shopping this comparison — provided you're trying to record and you care about high impedance studio headphones. The custom headphone amp, the 120dB dynamic range, the 24-bit/192kHz conversion, and the included software make it a complete recording front end rather than just a listening device, and it's the only one of the two whose design speaks directly to the high impedance question. I'd pick the Linsoul ZiiGaat x Fresh only if I wanted wired in-ears for listening and monitoring — and even then, I'd know it brings no noise cancellation, which matters if you're thinking about best open ear headphones for construction work or a best noise canceling kids headset for construction work. The Scarlett wins for me on versatility and purpose.
do high impedance headphones sound better
Not inherently — impedance changes how much voltage a source needs to drive a pair of headphones to a given loudness, not the tuning itself. What high impedance does demand is an amp with enough clean output, which is exactly why the Scarlett Solo 4th's custom headphone amp is marketed around driving high impedance loads. Pair a high impedance headphone with a weak output and it will sound quiet and thin; pair it with a capable one and it can reach its potential.
is high impedance good for headphones
It can be, in the right setup. High impedance designs tend to be less sensitive to the output impedance of the amp driving them, and they often pair well with dedicated studio gear. The catch is that they need more voltage, so a purpose-built headphone amp — like the one in the Scarlett Solo 4th — is the sensible match. The ZiiGaat x Fresh, at 24 ohm, is on the opposite end: easy to drive from a phone or laptop.
Not across the board. Impedance is a design choice, not a quality grade. The ZiiGaat x Fresh is a 24 ohm hybrid IEM with a 20Hz–40kHz range and plenty of driver engineering behind it, and it isn't "worse" for being low impedance — it's simply built for a different job. High impedance is better only when you're feeding it from a source that can supply the needed voltage.
why are high impedance headphones better
They aren't always — but they can be preferable in a studio chain because they draw less current and are less affected by the output stage of the amp, which can help keep noise down. The trade-off is that you need a headphone output with real voltage swing. That's the specific gap the Scarlett Solo 4th's headphone amp is designed to close, and it's why this pairing makes sense for a recording setup rather than casual phone listening.
Whichever way you lean, check the current price on Amazon before you commit — the two products sit in very different categories, and your budget will settle the argument fast.
