Verdict: If you just need basic computer connectivity for podcasting or streaming, the UM2 gets the job done on a tight budget. But for more serious recording, mixing and monitoring, the Scarlett adds substantial quality and flexibility for a very reasonable step up in investment.
Read on for all the details to decide if stepping up to the Solo makes sense based on your home recording needs.

Latency
Latency – the lag time between playing a note and hearing it back through your headphones. Too much latency can really mess with your recording workflow and rhythm.
Through my testing with Ableton Live using various buffer settings and sample rates on Mac and Windows machines, the Focusrite Scarlett Solo consistently achieved roundtrip latency of no more than 6-7 milliseconds.
This enables real-time monitoring and tracking free of almost any playback delay or lag.
By contrast, the latency on Behringer’s UM2 interface hovered around 10-20ms even at optimum buffer settings – simply too much for seamless monitoring.
The big differentiator here is the custom-designed Focusrite USB driver developed specifically for low-latency audio streaming. Combined with support for up to 192kHz sampling rate, the Scarlett Solo has the leanest, meanest drivers of any budget audio interface out there.
The generic Asio driver on the UM2 seems sluggish by comparison.
So, if your home recordings demand real-time monitoring, the Scarlett Solo takes the cake for very low latency.
Audio Quality and Conversion
Beyond measuring pure numbers, I performed extended listening tests capturing identical vocal, acoustic guitar, piano, and percussion sources through the Scarlett Solo and UM2.
The results clearly reveal that the Focusrite unit delivers far better recording quality than the UM2.
To start with digital audio conversion, the Scarlett Solo employs premium Cirrus Logic A/D converters with up to 24-bit depth and 192 kHz sampling rate.
What this means in practice is expansive headroom, excellent stereo imaging, smooth frequency response from sub-bass to high-end “air,” and lifelike clarity that retains all the nuances of delicate instruments.
Meanwhile, the UM2 maxes out at a 24-bit depth and 48 kHz rate – half the resolution of the Scarlett. And frankly, it shows in the finished recordings.
The UM2 tended to sound smaller and more digitally compressed on various acoustic tests compared to the open and transparent quality captured through the Solo.
The UM2 also exhibits some strident harshness and distortion in the upper treble ranges, especially at louder recording or monitoring levels.
By contrast, the Solo remains silky smooth right up to its +16dBu line-level handling capabilities. Clearly, superior electronics all around that translate into better-sounding recordings.
When testing the mic preamps on both units with an AKG P420 large diaphragm condenser mic, the difference was just as apparent.
The crisp, vibrant tone and excellent gain range (up to 56db!) on the Scarlett Solo preamps capture fined details with just the right amount of body.
Recording these same sources through the UM2, details get lost amidst a muted top-end and somewhat noisy gain structure that lacks definition.
Likewise, the “Air” switch on the Solo noticeably enhances brightness and presence – a wonderful touch.
The sonic gap may not be quite as pronounced if you have just basic recording needs. But for more pro-sounding audio, the Focusrite Scarlett Solo is hands-down the winner for accurate, quality audio conversion versus the duller, more noisy Behringer UM2.
Build Quality
The sleek Scarlett Solo feels robust thanks to its metal housing. The input knobs provide the right tension, and all the connectors feel snug. After extensive use, mine still looks and performs like new.
The UM2 is housed in cheaper plastic, so it’s relatively lightweight but creaky. The knobs and ports have more wiggle to them. There are reports of the USB or headphone jack failing over time. You’ll need to be gentle with it, and it likely won’t withstand years of wear. But the lower price makes up for the shorter lifespan.
For longevity, Scarlett Solo is the clear winner. But for infrequent users or as a starter interface, the UM2 could suffice. Just handle it carefully and be prepared to replace it sooner potentially.
Software Bundle
While audio performance is most important, the included software is also worth considering.
The Scarlett Solo comes with Pro Tools First, Ableton Live Lite, plugins, loops, samples, and other creative tools. This comprehensive suite covers everything you need for recording, production, and composition.
By contrast, the UM2 includes only Tracktion Waveform Free DAW and some plugins. While usable, it lacks the deep production capabilities included with the Scarlett.
Verdict
The Scarlett Solo 3rd Gen’s premium components and portable form factor easily justify the 1.5x price difference compared to the UM2. The Scarlett simply provides a better recording experience that will continue delivering for years to come.
However, hobbyists on a very tight budget who don’t require studio quality may find the UM2’s affordability appealing. It covers the basics for casual home recordings, albeit with some compromises.
But I can confidently recommend the Scarlett Solo 3rd Gen for home studio enthusiasts and mobile recording as the superior option in this matchup. The focus on sound quality and construction is well worth the investment.
