The Focusrite Scarlett Solo 3rd Gen is a solid audio interface that's perfect for casual use. The build quality is robust, and the setup is incredibly easy. Overall, it delivers impressive performance for the price. However, one feature that slightly annoyed me was the volume knob. On the 3rd Gen, the same knob controls both your headphone and speaker output. This can be a bit inconvenient when you're adjusting your setup, especially if you're frequently switching between headphones and speakers. It's not a dealbreaker, but it can get frustrating when you're trying to find the right balance.
That being said, I believe Focusrite addressed this issue in the 4th Gen model, which is a great improvement. If you're looking for a more refined experience with independent controls for headphones and speakers, the 4th Gen would definitely be the way to go.
