Headphones — Yamaha HPH-MT7W

The HPH-MT7W is the white-finished version of Yamaha's HPH-MT7 professional studio monitor headphone, part of the company's MT series. Yamaha designed it for mixing and recording in the studio and for mix monitoring in live performance, applying its experience in professional and high-end audio equipment to every acoustic component, with the aim of a flat response at any listening level. The same model is also available in black.

Key specs that matter

The HPH-MT7W is a closed-back, circumaural (over-ear) dynamic headphone with custom 40mm drivers using CCAW voice coils and neodymium magnets. Frequency response is 15Hz to 25kHz, sensitivity is 99dB/mW, impedance is 49 ohms at 1kHz and maximum input power is 1,600mW. The straight, single-sided 3m cable ends in a gold-plated 3.5mm plug, with a threaded gold-plated 6.3mm adaptor supplied. The headphone measures 170 x 195 x 98mm and weighs 360g. A padded carrying bag is included.

Engineering and use context

CCAW (copper-clad aluminium wire) voice coils combine the low weight of aluminium with the conductivity of a copper surface, reducing the moving mass of the diaphragm assembly so it can follow fast transients, while neodymium magnets give a strong motor from a compact, light structure. The closed-back, circumaural design encloses the ears, isolating the wearer from studio noise such as computers and drum kits and preventing headphone sound from leaking into nearby microphones during recording. The high power handling lets the headphone cope with the high levels needed on a loud stage without damage. Its moderate impedance lets it reach ample volume from mobile devices as well as from studio headphone amplifiers and mixing consoles. Large, low-resistance synthetic-leather cushions spread pressure around the ear for long sessions, and the three-dimensional pivoting arms with adjustable sliders fit a range of head shapes. The earcups can be rotated away from the ear for single-ear monitoring, useful for singers who want to hear their own voice in the room. Build quality suits professional work - a thick ABS housing, die-cast aluminium support arms and a sweat-resistant headband. The single-sided straight cable keeps the lead on one side and gives freedom of movement for performers.

Pairing

The HPH-MT7W connects directly to audio interfaces, mixing consoles, studio headphone amplifiers and portable players through its 3.5mm plug and 6.3mm adaptor. It suits stage monitoring and loud control-room work.

Alternatives

Yamaha's own HPH-MT8 is a closed-back monitor headphone with larger 45mm drivers and a detachable cable.
