Short answer: the Edifier MR4 has been measured and ranked among powered bookshelf speakers; the Midiplus MI5 II V2 has not been independently measured yet, so until it is, this comes down to features and price.
The case for the Midiplus MI5 II V2: The second generation of Midiplus’s larger powered monitor pair: a 5.25” woven fiberglass woofer and a 1” silk dome tweeter behind a metal mesh guard in each wooden, rear ported cabinet, driven by 2x 35W of Class D power.
On the Edifier MR4 side: 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.
Buy the Edifier MR4 if you want a speaker whose sound quality has been measured and ranked.

The Two Speakers In Full
Midiplus MI5 II V2 eBay
Older model: the Midiplus MI5 II (rated 3/5).
Pros: The second generation of Midiplus’s larger powered monitor pair: a 5.25” woven fiberglass woofer and a 1” silk dome tweeter behind a metal mesh guard in each wooden, rear ported cabinet, driven by 2x 35W of Class D power. Inputs cover balanced 1/4” TRS, RCA, a 3.5mm aux input and Bluetooth 5.0. Midiplus rates it at 60Hz to 20kHz.
Cons: No independent measurements have been published yet, so its tonal balance can’t be compared with ranked speakers. The MI5 II it replaces measured poorly on spinorama.org (a 2.24 preference score, with a wide 9.4dB midrange span), and there is no data yet showing whether the V2 improves on it. It has no subwoofer output for extending the bass below its 60Hz rating. It is mainly sold through Midiplus’s European and Asian distributors, with no US retailer yet.

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.
