Sony MDR-M1 review

The MDR-M1 is Sony's newer closed-back reference monitor, and it is the strongest choice here if you want one pair for every stage of a home production. Sony says it worked with industry engineers on the tuning and lists a 40 mm dynamic driver that reproduces 5 Hz to 80 kHz. The closed acoustic structure is built for high sound isolation, so you can track vocals with it, while Sony positions it for mixing and editing as well. At about 216 g without the cable it is the lightest closed-back pair on this list, and the soft, thick ear pads are designed for long sessions. Cables detach with machined aluminum screw-lock connectors, and the box includes two 3.5 mm cables of different lengths and a 6.35 mm adapter. With 50 ohms and 102 dB/mW sensitivity, Sony says it runs from interfaces and laptops without an external amp. The main drawback is price: $269.99 is well above the MDR-7506. We compared documented features and published prices; we did not test it.
