Short answer: the Edifier MR4. It ranks #48 of 67 powered bookshelf speakers by sound quality, rated 3.5/5, at $139.99; the Midiplus MI5 II ranks #62, rated 3.0/5, and costs $169, which makes this an easy call rather than a real tradeoff.
Why pick the Midiplus MI5 II: Balanced inputs, Bluetooth and a powered-pair format offer useful connectivity. Watch for: The 2.24 standalone and 4.53 ideal-subwoofer scores show significant problems above the bass region.
Why pick the Edifier MR4: Erin’s data supports a useful budget desktop monitor: a 3.0dB midrange span, little overall on-axis tilt, and preference scores of 3.25 standalone and 6.00 with an ideal subwoofer. The tradeoff: Bass reaches -3dB around 79Hz, so deep extension should not be inferred from the overall flat trend.
Buy the Edifier MR4. It is rated higher for sound quality than the Midiplus MI5 II and costs less, so there is no real case for the other one.

Midiplus MI5 II: $169 per pair eBay
Pros: Balanced inputs, Bluetooth and a powered-pair format offer useful connectivity. The measured -3dB point is around 54Hz, so it reaches lower in the bass than some compact monitors.
Cons: The 2.24 standalone and 4.53 ideal-subwoofer scores show significant problems above the bass region. A large 9.4dB midrange response span and listening-window narrow-band deviation of 0.644 indicate substantial coloration even though the overall response slope is fairly mild. A subwoofer cannot fix those irregularities. Amplifier-power specifications do not establish clean output.

Edifier MR4: $139.99 per pair Amazon eBay
Pros: Erin’s data supports a useful budget desktop monitor: a 3.0dB midrange span, little overall on-axis tilt, and preference scores of 3.25 standalone and 6.00 with an ideal subwoofer. Balanced TRS inputs and tone controls are practical at its price, and its response is more balanced than the measured R1280T. Measured bass extension of 79Hz (-3dB), with a measured sensitivity of 78dB.
Cons: Bass reaches -3dB around 79Hz, so deep extension should not be inferred from the overall flat trend. Listening-window response still has local irregularities, including lower-treble unevenness. The existing review reports rapidly increasing distortion and audible distress when pushed well above moderate desktop levels. No Bluetooth, and adding a subwoofer does not cure every output or tonal limitation.
