Short answer: the Edifier MR3. It ranks #8 of 24 powered bookshelf speakers by sound quality, rated 3.8/5, at $109.99; the Midiplus MI3 II ranks #23, rated 2.4/5, and costs $139, so there is not much of a tradeoff to weigh.
The case for the Midiplus MI3 II: Compact cabinets, Bluetooth, analog inputs and high-frequency adjustment can suit a basic desktop system. The tradeoff: Preference scores of 0.99 standalone and 3.84 with an ideal subwoofer are poor.
The case for the Edifier MR3: Erin’s measurements show little overall tilt across the listening window, helping voices retain a broadly natural balance at a desk. Watch for: Local response ripples remain: the measured 300Hz-5kHz span is 4.5dB and listening-window narrow-band deviation is 0.538.
Buy the Edifier MR3. It is rated higher for sound quality than the Midiplus MI3 II and costs less, so there is no real case for the other one.

Midiplus MI3 II: $139 per pair eBay
Pros: Compact cabinets, Bluetooth, analog inputs and high-frequency adjustment can suit a basic desktop system. The measured -3dB point is about 67Hz, so missing bass is not its only differentiator from other tiny speakers.
Cons: Preference scores of 0.99 standalone and 3.84 with an ideal subwoofer are poor. High narrow-band deviations on-axis (0.938) and across the listening window (0.852) indicate pronounced response irregularities that can color voices and instruments. The fairly flat overall trend does not mean the response itself is smooth. A subwoofer or simple treble adjustment cannot resolve all of these problems.

Edifier MR3: $109.99 per pair Amazon eBay
Pros: Erin’s measurements show little overall tilt across the listening window, helping voices retain a broadly natural balance at a desk. Scores of 3.91 standalone and 6.53 with an ideal subwoofer support it as a useful budget nearfield option rather than a reference monitor. Tone controls and app-based EQ provide unusually flexible adjustment, and its bass extends farther than the Fostex PM03’s. Measured bass extension of 70Hz (-3dB), with a measured sensitivity of 83.3dB.
Cons: Local response ripples remain: the measured 300Hz-5kHz span is 4.5dB and listening-window narrow-band deviation is 0.538. Bass reaches -3dB at about 70Hz. The limiter protects the drivers but prevents much extra loudness when pushed; existing compression testing puts effective single-speaker output around 86-87dB at 1m. Vertical crossover interference makes tweeter height and tilt important.
