Ranked by what users actually praise

Overall Impression

A clear technical upgrade over previous Scarletts, inspired visibly by Audient's EVO design. Multiple commenters note Focusrite finally moved past the 'more of the same' feel of Gen 2/3, citing improved smart gain, LED indicators, and a UI that closely mirrors Audient's EVO series. The returning top-mounted buttons and improved mixer with loopback and monitor/headphone switching presets were called out as welcome, overdue changes making the workflow feel more modern and flexible.

The headphone output remains the interface's most criticized weak point. Several users flagged the still-high output impedance (11 ohms, versus 50 ohms on the smaller 2i2/Solo) and a headphone amp many said 'doesn't sound great,' especially with low-impedance headphones where audible bass differences were reported. Comparisons to SSL2+, Apogee Boom, and Clarett+ suggest users feel Focusrite has yet to catch up to competitors here, despite other gains.

USB-C bus power and missing power switch caused real practical friction. Multiple commenters ran into power issues traced to USB-C ports not supplying enough wattage/amperage, requiring Thunderbolt-rated ports or external power, with one troubleshooting for hours before finding a fix. Others criticized the lack of a physical power switch at this price point, and one reported an always-lit ring light even when the computer is off, calling it a corner-cutting design choice.
