How we researched
This review is based on 7Hz Legato's official product page, its published specifications and pricing, and a comparison with leading alternatives in tech & gadgets. We have not used this product ourselves; scores reflect how it compares on paper.What the 7Hz Legato is
The Legato is a wired in-ear monitor (IEM) from 7Hz, sold in the US through Linsoul. 7Hz says it was the brand's first dual dynamic driver design, introduced in spring 2023.
It uses two dynamic drivers per side: a 12mm woofer for the low end and a 6mm driver for mids and treble. The shells are machined aluminum, and the cable detaches at a standard 0.78mm 2-pin connector.
This is not a wireless earbud and has no microphone. It is aimed at people who listen from a computer, a portable DAC or a music player.
Key features and the brand's claims
7Hz says the 12mm woofer uses a multi-layer composite diaphragm with an N52 magnet for bold, punchy bass with deep rumble. The spec sheet lists a fourth-generation DLC composite diaphragm. The 6mm driver, according to the brand, uses a double-cavity structure and a rigid, low-mass metal diaphragm for treble.
The two drivers are split by a crossover that 7Hz says was designed around the drivers' characteristics, using eight Japan-made audio-grade tantalum capacitors. These are the brand's claims about design intent, not measured results.
The cable is a blend of OCC copper and silver-plated OCC copper with a 3.5mm plug. Because it detaches, you can swap in a balanced cable or one with a mic later.
What buyers report about the sound and fit
The product page shows 35 buyer reviews, with 26 five-star and 7 four-star ratings. Nearly all of them focus on the bass, describing it as heavy, deep and well suited to EDM, drum and bass, rock and gaming.
The criticism is consistent too. Several reviewers say the bass bleeds into the midrange, some vocals sound recessed, and the treble is smooth to the point of lacking sparkle. One buyer felt it had about 3dB too much bass and changed ear tips to tame it.
On practical matters, a few buyers say it sounds best with a stronger source and is not very loud from a phone alone. Others mention swapping to aftermarket tips for a better seal, and one found the nozzle somewhat large. Buyers generally describe the metal shells as solid and comfortable.
Price and value
Linsoul lists the Legato at $98.10 on sale, down from a regular $109. Standard shipping is free to most countries, but import taxes and fees are the buyer's responsibility, and standard delivery can take 2 to 4 weeks or longer.
The official box contents list only the earphones and a user manual. Some buyer reviews mention a hard case, extra filters and multiple ear tips, so check the listing at purchase time rather than counting on them.
For a metal-shelled, dual dynamic IEM with a detachable cable, the price is reasonable. Value depends heavily on whether you actually want this much bass, and on whether you need to budget for a dongle DAC or new tips.
Who it suits
The Legato makes the most sense for listeners who already know they like a warm, bass-forward sound. Buyer reviews repeatedly call it fun rather than analytical.
It is a weaker fit for critical listening, vocal-focused music, or anyone who wants crisp, bright treble. Several reviewers say outright it is not for studio-style monitoring.
If you take calls on your earphones, plan on buying a 2-pin cable with a mic, since the stock cable does not have one.

FAQ
Is the 7Hz Legato good for bass?
Bass is the Legato's main focus. 7Hz says its 12mm woofer is built for punchy, deep bass, and most buyer reviews on the seller's page praise the low end. Some buyers also say the bass can spill into the mids.
Does the 7Hz Legato have a microphone?
No. Linsoul confirmed on the product page that the Legato does not come with a mic. Because it uses a standard 0.78mm 2-pin connector, you can buy a compatible cable with a microphone separately.
Do I need an amp for the 7Hz Legato?
Not strictly. It has a listed impedance of 26 ohms and sensitivity of 108dB/V, and some buyers run it straight from a PC. Others say it is not very loud from a smartphone and sounds better with a dongle DAC or amp.
Is the 7Hz Legato good for gaming?
Several buyers say they use it for PC gaming and like its heavy bass for explosions and effects. It is wired with a 3.5mm plug and has no mic, so you would need a mic cable or a separate microphone for voice chat.
What is the warranty and return policy?
Linsoul lists a 1-year warranty on the earphones and 3 months on the cable. Returns are accepted within 30 days only if the product is still factory sealed; damaged or faulty items are assessed case by case.
Final verdict
The 7Hz Legato is a solid pick for bass fans who want a metal-built wired IEM around $100, and buyer feedback largely backs up its bass-first design. Its relaxed treble, reported bass bleed and lack of a mic make it a poor match for neutral-sound seekers or phone-only users. Buy it if heavy bass is the goal; skip it if detail and balance come first.
