Edifier's MR4 is the runner-up in this guide: a compact 2.0 desktop studio monitor at £98.99, holding 4.6 out of 5 from 3,160 ratings, with a 4-inch woofer, a 42W RMS Class D amplifier and TRS, RCA and AUX inputs. The listing gives the colour as white and the enclosure as wood (MDF) and plastic.

The numbers inside its own listing do not agree with each other. One bullet says the SNR "can reach up to 99dB"; the Signal-to-Noise Ratio field in the spec table says 85 dB. The Frequency Response field gives a single figure, 20 KHz, rather than a range. The same table carries a Battery Average Life of 6 Hours and a Control Method of Touch on a speaker the listing otherwise presents as a tabletop, mains-powered monitor — and a review below describes reaching for the knobs on the back. Everything on this page comes from the Amazon listing as published, not from testing we carried out.
