Edifier MR4

The short version

What to know.

A small ported two-way with unusually good horizontal dispersion for the money and an uneven response: three Klippel datasets show a dip around the 2–4 kHz crossover, small resonances near 600 Hz and 1.2 kHz, and useful bass to about 65–70 Hz, for a spinorama.org preference score of about 3.3 (6.0 with a subwoofer). Sources agree on wide imaging and soundstage at a desk, solid value, sensible analog I/O and a fiddly stepped volume knob. They split on bass (full for the size vs thin without a sub), on treble and mids (the lab's dip vs listeners' "crisp and clear"), on how loud it can go (fine at a desk, strained above about 90 dB at a metre), on hiss, on build, and on whether it is a real mixing monitor or a very good computer speaker.

About this product

Edifier's 4-inch desktop studio monitors from 2021, sold as a black or white pair: the right cabinet holds the amplifier, controls and inputs and drives the passive left one over speaker wire. Not the bi-amped MR4.5, the smaller Bluetooth MR3 or the MR5. A pair costs about $140 in the US as of September 2026 ($170 list).

Edifier's MR4 arrived in late 2021 as a desktop studio monitor: a $130 pair of 4-inch two-ways with a molded waveguide, balanced TRS inputs, a front headphone jack and a knob that flips between Monitor and Music voicings. It quickly became the standard answer to "what should replace my computer speakers?"

Its reputation rests on an unusual alliance. The Klippel-scanner labs liked it: Erin's Audio Corner called it the best speaker he had tested at its size and price, and Audio Science Review a decent option with a little EQ — while both pointed to an uneven treble and a low ceiling on volume. Owners and magazines mostly love it; the arguments are about hiss, bass and whether a speaker this small should be trusted with a mix.

A good fit for

  • Upgrading from computer speakers on a desk, listening from 1–3 ft
  • Video, podcast and content editing where a reasonably honest midrange and good imaging matter more than deep bass
  • Owners who will apply the public EQ settings — the response takes EQ well
  • A small desk that can't fit a 5-inch monitor such as the JBL 305P MkII

Think twice if

  • You need deep bass or high volume without adding a subwoofer
  • You're hiss-sensitive and will sit within a couple of feet with the knob turned up
  • You want a monitor accurate enough to make final mix decisions without checking elsewhere
  • You want Bluetooth, USB or a sub output

The reviewer consensus

Agreement &
disagreement.

7 / 15topics divide opinion
4 Strong agreement4 Mostly agree7 Divided opinions

Common ground5

  • Wide, well-centred stereo image and soundstage at desk distance, helped by even horizontal dispersion
  • Strong value for a pair at about $140 — Erin rates it the best he had measured at its size and price, and Amir a decent option
  • Good analog I/O for the money: balanced TRS, RCA, front aux and headphone jack

Points of contention6

  • Bass: surprisingly full for 4 inches vs light without a subwoofer
  • Treble and mids: the lab's crossover dip and 600 Hz resonance vs listeners' "clear and crisp" and "full"
  • Loudness: plenty at a desk vs strained above about 90 dB at a metre

Mostly praised by ear, qualified by the lab. TechRadar, Mighty Gadget, techreviewer.de, Passion for Sound, Kyle Erickson and most owners call it balanced — "not flat", perhaps a touch warm or with a little upper-mid lift, but honest enough to edit on. Amir and Erin measured a response that is "not the most neutral" (roughly ±3 dB) with a treble dip and small midrange resonances, though Amir found it "warm and reasonably nice sounding" and both say it takes EQ well. A minority of owners hear it as boxy, muddy or thin.

“First impression defies the look of the measurements: the sound is warm and reasonably nice sounding.”

Amir, Audio Science Review

“I wouldn’t describe the overall sound as flat, but it is well-balanced.”

James Smythe, Mighty Gadget

“The highs sound awesome, and mids and lows sound good, but overall sounds boxy.”

Measured

Klippel NFS (ASR 2021, Erin 2022) plus Audio Lab Insight's Klippel data (2024): on-axis roughly within ±3 dB above the bass but with a scoop through the 2–4 kHz crossover region, resonances near 600 Hz and 1.2 kHz, and a predicted in-room response tilted toward the treble. spinorama.org preference score 3.25–3.4 across the three datasets (about 6.0 with an ideal sub) — against 1.5 or lower for the PreSonus Eris 3.5 2nd Gen.

vs. listeners — The listening camp is larger than the graphs might suggest. Amir said the sound "defies the look of the measurements", and Erin found the midrange resonance inaudible; the lab's complaint is mostly about a mixing monitor's standard, not a desk speaker's.

The powered right cabinet drives the passive left one over speaker wire (21 W + 21 W). A front headphone jack mutes the speakers; the front knob also switches Monitor and Music modes.

What to keep in mind 5

  1. A read of where the reviews and measurements stand as of September 2026. The MR4 dates from 2021, and newer small monitors — including Edifier's own MR3 — keep moving the comparison.

  2. Speakers depend on the room and the desk more than anything else. Bass in particular changes with the distance to the wall behind them, and hiss depends on how close you sit, so claims here name the setup they came from where the source gave one.
