Choosing your first interface often comes down to these two titans. While the Focusrite Scarlett 2i2 (4th Gen) is the world’s most popular interface, the PreSonus AudioBox GO has emerged as the ultimate “ultra-portable” contender.
Based on technical benchmarks and driver stability research, here is the straightforward comparison for beginners.

1. Focusrite Scarlett 2i2: The “Grow-With-You” Choice
The 4th Gen Scarlett is objectively superior in audio fidelity. Its 120dB dynamic range is backed by the same converters found in high-end RedNet studio systems.
- Why Beginners Love It: The Auto Gain button listens to your voice and sets the perfect level automatically. The Clip Safe feature uses AI-driven monitoring to lower the gain if you suddenly get too loud, preventing a “clipped” or ruined take.1
- The “Air” Mode: Research into psychoacoustics shows that the Scarlett’s “Air” mode adds a high-frequency lift (mimicking classic ISA preamps) that helps vocals “cut through” a mix without needing complex EQ.2
2. PreSonus AudioBox GO: The “Budget & Mobile” King
If you are a student or a traveling songwriter, the AudioBox GO is the most logical choice. It is significantly smaller and costs less than half the price of the Scarlett.
- Connectivity: It is one of the few budget interfaces designed specifically to work seamlessly with iPads and Android devices without needing an external power hub.
- Software Advantage: It comes with Studio One Prime, which research often cites as the most intuitive DAW (Digital Audio Workstation) for absolute beginners compared to the steeper learning curve of Ableton Live.
The Verdict: Which Should You Buy?
- Buy the Focusrite Scarlett 2i2 if: You want “studio-standard” sound quality, plan to record two microphones at once (like a podcast or acoustic guitar), and want AI tools to handle the technical side of recording for you.
- Buy the PreSonus AudioBox GO if: You are on a strict budget under $100, you primarily record on your phone/tablet, or you only need to record one microphone at a time.
Research Note: Benchmark tests show that while the Scarlett has lower noise floors, the AudioBox GO’s XMAX-L preamps provide a “warmth” that many beginners prefer for direct-input electric guitars.
