Logitech MX Sound 2.0  \n**Why it's great:**  \n- Has 3.5 mm input, dual 3.5 mm jacks (aux in + headphone out) for switch-over via hardware. ([pcgamer.com](https://www.pcgamer.com/logitech-mx-sound-20-speakers-review/?utm_source=openai))  \n- Offers solid sound quality with more power (~24 W peak / ~12 W RMS) compared to entry-level speakers. ([macrumors.com](https://www.macrumors.com/review/logitech-mx-sound-2-0-speakers/?utm_source=openai))  \n\n---\n\n### \ud83d\udee0 Recommendation Summary\n\n| Model         | USB-Powered? | 3.5 mm Aux Input | Headphone Jack On-Speaker | Strengths / Trade-Offs |\n|----------------|---------------|------------------|-----------------------------|-------------------------|\n| **Z150**       | \u2705             | \u2705               | \u2705                          | Best all-round pick for budget desk setups. |\n| **Z110**       | \u2705             | \u2705               | *No clear info*            | Ultra compact; good for tight spaces. |\n| **Z120 / Z120BW** | \u2705        | \u2705               | *Version-specific*         | Very small, lowest power output. |\n| **Z200**       | \u274c             | \u2705               | \u2705                          | Better bass & control, but needs wall power. |\n| **MX Sound 2.0**| \u274c             | \u2705               | \u2705                          | Much higher quality and power if budget allows. |\n\n---\n\nIf USB power *must* be non-negotiable (i.e. no wall adapter), then **Z150** is the strongest option. The **Z110** might also qualify if the version has headphone jack. The **Z200** and **MX Sound 2.0** deliver much more power and features, but give up on USB-only power.\n\nIf you want, I can pull up price comparisons or similar alternatives outside Logitech that match your specs at different budget levels\u2014would you like that?"
