Focusrite Scarlett Solo Studio (4th Gen) review

Not an interface but a package: the Solo 4th Gen already published here, plus the CM25 MkIII condenser microphone and the SH-450 headphones, with the same 120 dB converters and the same software.

What it amounts to The one-order answer to a first recording setup, built around an interface this site already publishes. What is in the box is named and not specified: the microphone and the headphones arrive with no figure attached to either.

This is a bundle, and saying so is the first job of this page. Inside it: the Scarlett Solo 4th Gen interface — which is published separately on this shelf — the CM25 MkIII microphone and the SH-450 headphones.

So the interface question is already answered elsewhere. 120 dB dynamic range, the same converters Focusrite states it uses in its flagship units, Air mode, one microphone preamp and one instrument input, and the four-piece software bundle. All of that is the Solo, at around $130 on its own.

The question this page exists to frame is the other $160: what the microphone and the headphones are.

And the answer is that the listing does not say. The CM25 MkIII is named and nothing else — no polar pattern, no diaphragm size, no sensitivity, no maximum SPL. The microphone shelf on this site shows what those figures look like when a maker publishes them, and how much they decide. The SH-450 headphones are named and nothing else — no driver size, no impedance, no frequency response. The headphone shelf here shows two pairs publishing all three.

That is not an accusation. Matched accessories from the interface maker are a real argument: the microphone will work with the preamp, the headphones will be driven by the output, and neither needs choosing on a first purchase. It is simply an argument about convenience rather than about specification, and a reader deserves to know which one they are being offered.

The product record gives 1,370 g (48.3 oz), which is three objects and a box.

In its favor, and its limits

Strengths

  • The three objects a first recording needs, in one order, from one maker
  • The same 120 dB converters and the same software as the interface bought alone
  • The microphone and the headphones are matched to the interface by the maker rather than guessed at

Compromises

  • The microphone and the headphones are published by name only — no pattern, no impedance, no driver size, no response
  • The interface inside it is already published on this shelf, and the price difference is what the two accessories cost
  • One microphone preamp, so the bundle records one source at a time

The questions players ask

Is this different from the Solo already on this shelf?

It contains it. The Scarlett Solo 4th Gen interface is published separately here at around $130; this bundle is that interface plus the CM25 MkIII microphone and the SH-450 headphones at $289.99. So the question is not which interface is better — they are the same one — but whether the microphone and the headphones are worth the difference. This page cannot tell you, because the listing publishes nothing measurable about either of them.

What is published about the microphone and the headphones?

Their names. That is the finding. The microphone shelf on this site shows what a condenser listing normally publishes — a pattern, a diaphragm size, a sensitivity, a maximum SPL — and the headphone shelf shows an impedance, a sensitivity and a driver size. For the CM25 MkIII and the SH-450 this bundle publishes none of it. They are matched to the interface by the maker, which is a real argument; they are not described.

Who should pick this one, among music instruments and gear

A first recording setup where one order beats three, and the microphone and headphones do not need to be chosen.
