If you Google “Scarlett Solo vs 2i2,” you’ll find dozens of articles that spend 2,000 words explaining the differences and then conclude with “it depends.” This is not helpful. The answer is actually simple, and by the end of this article you’ll know exactly which one to buy.

The Short Answer

If you will only ever record one source at a time, buy the Solo (€119). If there's any chance — any chance at all — that you'll record two sources simultaneously, buy the 2i2 (€159). The €40 difference is not worth regretting.

What’s Actually Different Between Them

The Scarlett Solo and the 2i2 are, in most ways, the same interface. They use the same USB-C connection, the same drivers, the same Focusrite Control software, and virtually the same preamp design. The differences are:

  • Inputs: The Solo has one XLR/TRS combo input for a microphone, plus one dedicated instrument (Hi-Z) input. The 2i2 has two XLR/TRS combo inputs, both of which can accept either a microphone or a line-level signal.
  • Price: Solo is €119. The 2i2 is €159. A €40 difference.
  • Outputs: Both have the same stereo output on the back for monitors and the same headphone output on the front.
  • Size: The 2i2 is slightly larger and heavier, which matters for some portable setups.

That’s it. There’s no meaningful difference in sound quality, latency, driver performance, or reliability. This is purely a capacity decision.

Who Should Buy the Solo

The Solo is the right choice if you fall into one of these categories:

  • You record only one microphone at a time, always, and you’re certain this will never change
  • You’re a singer-songwriter who records vocals only (no simultaneous guitar)
  • You’re a podcaster recording only yourself
  • You make entirely electronic music and only need to record MIDI, with no acoustic sources
  • You need to save the €40 for something else and have thought about your workflow carefully

If you match all of these, the Solo is an excellent interface and you won’t regret it.

Who Should Buy the 2i2

The 2i2 is the right choice in any of these situations:

  • You record acoustic guitar and vocals simultaneously (singer-songwriters do this constantly)
  • You run a podcast or do interviews with a second person in the room
  • You play live piano or keyboards into your DAW (stereo instrument requires two inputs)
  • You want to record a band, even just two members at a time
  • You’re not sure — the uncertainty itself is a reason to buy the 2i2
The most common Solo regret: "I bought the Solo because I thought I'd only record one thing at a time, but then I wanted to record acoustic guitar and sing at the same time." This scenario comes up for nearly every musician eventually. The 2i2 prevents it.

The One Scenario Where Neither Is Right

If you need more than two inputs simultaneously — recording a drum kit, a full band, or anything requiring three or more microphones at once — the Scarlett 2i2 is not the right tool regardless of price. You’ll want to look at the Focusrite Scarlett 4i4 (€249) or the PreSonus AudioBox 96 Studio for multi-input recording.

For most home studio producers, this isn’t relevant. Two inputs covers nearly everything.

Our Recommendation

Buy the Focusrite Scarlett 2i2. The €40 difference between the Solo and 2i2 is the cheapest insurance policy in home studio production. One day you’ll want to record two things at once, and when that day comes, you’ll be glad you bought the 2i2.

The only exception: if you are 100% certain you will never record two sources simultaneously, and €40 genuinely matters to your budget, the Solo is a completely excellent interface that will serve you well.
