7Hz Legato is a brand new dual-driver in-ear monitor featuring two high-performance dynamic drivers on each side. The pair houses a 12mm and another 6mm dynamic driver where the 12mm one acts as a woofer and produces a powerful lower-end response, the 6mm driver here is kept responsible for exceptional midrange clarity and treble response. With professional tuning and precise adjustments, 7Hz Legato packs a powerful and lively sound that complements different genres of music well!!
Premium Dual-Driver Arrangement For Exceptional Sound
7Hz has got years of experience in designing dynamic driver IEMs. They have used that expertise in designing the all-new Legato with a dual dynamic driver arrangement. The pair houses a large 12mm dynamic driver with a multi-layer composite diaphragm as a woofer paired with a 6mm dynamic driver with a composite diaphragm for powerful sound delivery. The 12mm unit used high-power N52 Neodymium magnets that produce a powerful magnetic flux allowing for swift movement of the diaphragm coil enabling clean and precise sound.
High-Power Woofer & Crisp Mid-High Drivers
The 12mm dynamic driver unit produces a powerful lower-end response. It delivers impactful slams in the mid-bass region and extends deep into the sub-bass region producing a powerful rumble that adds heft to the output signal. The 6mm dynamic driver unit produces clean and accurate midrange and high-frequency responses. The output is coherent with each frequency producing a crisp response that is in line with the other frequencies.
Professional Crossover Circuit With 8 Japan-Made Audio-Grade Capacitors
Both the drivers are arranged together in a unique crossover which is specially developed using high-quality japan-made audio-grade tantalum capacitors. They ensure sufficient cured is supplied to the drivers allowing them to produce better sound.
Premium CNC Machined Aluminum Alloy Ear Shells
7Hz has featured high-quality CNC machined aviation-grade aluminum alloy ear shells that have a premium finish and an ergonomic shape. The ear pieces look spectacular, they are designed using high-precision measurements for a comfortable fit and firm wearing experience.
High-Purity Stock Cable
In order to ensure a high-quality signal, 7Hz Legato comes packed with a high-purity stock cable. It’s an OCC+Silver-Plated OCC hybrid cable that is crafted using high-quality materials for the best performance. The cable uses standard 0.78mm connectors and 3.5mm single-ended termination.
Overall, the 7Hz Legato package can be described as above standard for the price. It comes with a large, easy-to-use carrying case.

REW Frequency Response
Sound quality description
In this review, I use the standard eartips size L and drive it with the FiiO M15.
The 7Hz Legato has a V-shaped sound signature, leaning toward the lower frequencies with neutrality in mind.
Please see here for detailed reviews on sound quality.
Lows / Bass
The low frequency range of the 7Hz Legato is quite linear and deep.
The bass drum is tight, with excellent weight and plenty of impact. Rumble may be slightly lacking, but you won't find it lacking.
The electric bass is also sufficiently black and expansive.
Low frequencies are generally excellent in both quantity and quality, and will fully satisfy bass lovers, but they tend to be too strong for the mids.
The midrange of the 7Hz Legato is tuned for three-dimensionality, with an emphasis on depth and staging.
The left and right sides are wide, with a sense of depth and generous space, which makes for good listening comfort, but the reproduction of the three-dimensionality of music is poor because the sense of edge and crunch is too lacking, giving the impression of poor separation in the mid-range. Sound contours are too round, and the axes of violins and woodwinds are too squishy and soft, giving the impression that it is difficult to feel a sense of touch. The sound is rich and immersive, and some may find this kind of sound immersive and pleasant, but I do not like this kind of overly soft midrange.
The midrange can be improved by simply lowering the lower midrange to mid-low range with the equalizer.
However, there is a point in the upper midrange where there is probably a large amount of crossover distortion, which also affects the frequency response. The strong impression of muddiness in the midrange is likely to be affected by this as well.
Either way, the midrange is not really suitable for audiophiles. Resolution is also low.
Highs / Treble
The 7Hz Legato is adjusted with relatively high sound image consistency, with excellent localization and at the same time high definition and no lack of detail. Luminance, however, is a bit low and lacks subtlety. Extension is a little less than standard, but not insufficient.
The violins are not quite upright, but they are relatively straight, and the woodwinds are well extended, so the vertical axis is reasonably well defined even when listening to a full orchestra, although there is a little wobble in the upper part of the sound.
The cymbal crash lacks brightness in the upper part of the sound, so it can easily sound dark and lacks a bit of subtlety, which may give a somewhat muddy impression. The cymbal system is basically not tight enough, and it is easy to hear it poorly.
Sound quality general comment
On a macroscopic level, the 7Hz Legato are not bad IEMs in its price range. It has gone from the typical style of neutral tuning to increasing low frequencies and, following a recent direction, extending the highs appropriately, with reasonable extension in both the ultra-low and ultra-high directions.
However, the downside of such tuning is mainly concentrated in the midrange, which is the center of the spectrum. The midrange is cramped, muddy, and lackluster as a whole. At the very least, audiophiles with a fidelity to the original sound will not appreciate it, as it deviates from the recent basic principle of earphone design, which is to tune the midrange, the heart of the music, as carefully as possible.
If you like strong low-frequency sounds, it may not be bad.
Sound quality features
- Heavy and deep low frequency range
- Good detail
- Good localization
- Sound with a sense of depth
- Sufficiently extended highs
- Rich and immersive sound
- Unnatural texture
- Cramped midrange
- Muddy, hard-to-hear midrange
The 7Hz Legato IEMs have a V-shaped sound that combines massive, deep lows with sufficiently extended highs. The depth, rich resonance, and immersive sound may be quite attractive for relaxed listening applications. However, the mid-range is not well-developed and tends to sound muddy, making them not suitable for audiophiles.
