Description
The single-driver, Salnotes Zero was highly regarded by the audiophile community. ‘Legato’ means a ‘smooth transformation’. 7Hz is smoothly transforming audiophile listening from a single dynamic driver to the dual-driver 7HZ Legato in-ear monitor. Experience pure audio bliss with this IEM.
Dual-Drivers that Drive an Impressive Performance
Enjoy the high-fidelity performance with enhanced audio output with the 7Hz Legato. The 12mm woofer is engineered with a powerful N52 magnet and customised multi-layer composite diaphragm for a bold, punchy and deep sound. The 6mm tweeter and mid-range driver use a double-cavity structure with a highly rigid custom-made metal diaphragm. It has a low mass for exceptional treble.
The Crossover We Were Looking Forward To
The 7Hz Legato uses a unique crossover design consisting of 8 Japanese audio-grade Tantalum capacitors for highly precise and stable performance. This crossover has been specially developed according to each driver’s characteristics for better details, tonality and sound.
Looks Just as Smooth
The CNC-processed aviation-grade aluminium body offers a durable and precise fit. The threaded pattern on the faceplate keeps fingerprints away while creating a modern look. The detachable silver-plated OCC+OCC cable is crafted to ensure an optimal listening experience.

It can be a bit too much for normal melodious indian songs, but for bass heavy music like OSTs, party, rap, pop, EDM etc its very good.
Thanks for the review! IEMs are great for bassheads because they provide a tighter bass response. For normal melodious Indian songs, the Legato Dual Dynamic Drivers IEM may be a bit too much. However, for bass heavy music like OSTs, party, rap, pop, and EDM, they're great. Thanks for the feedback!
The 7Hz Legato is an overwhelming bass iem that needs EQ tuning to unleash its true potential. The sub-bass and mid-bass are truly elevated to the extent it bleeds into the mid frequencies. You may sometimes feel the vocals are suppressed. That's why the EQ need to be tuned. The treble is clear and airy with little or no sibilance at high volume. For tracks with multiple instruments or complexities, you may want to bring down the preamp. The 7Hz Legato has to be systematically tuned for critical listening. It's a must-have in a bass-head's collection. The fit is a cause for concern due to its size and weight. You will have to try different ear tips for that comfortable fit. All in all, a wonderful iem that will blow you away with its thundering bass.
Thank you for your review. We're glad to hear that you're happy with the 7Hz Legato IEMs.
These definitely are best sounding earphones in all aspects (like bass, mids, and treble).
The performance of these earphones is top notch.
These are going to provide good sub-bass and overall listening experience.
No look for anywhere else if someone loves bass.
As usual TAS" fastest delivery is awesome.
Thanks for the review.

Thanks to Pritam for his exceptional customer service and deal .
Definitely recommended

Have a great features and I am very happy after buying this m71 thanks audio store 🙏🙏

Time Spent with this DAP is more than 50 days, used many IEMs from Budget range to high end.
OBSERVATION & EXPERIENCE SO FAR.
- Wide soundstage, it's creating a spacious listening experience.
- Smooth and refined sound, with good bass & trebles. I liked it.
- little high Volume doesn't hurt ears because of spaciousness which this DAP creates.
- Main unique point is Vocals & Instruments separation, it's best.
- So far, I noticed Battery back up is really good. Will check it over time and provide feedback.
- Does not get warm that too after using for hours.
- Best software & Shanling Music app, it's very fast ( I use 1TB fully loaded Micro SD card.)
Please Note - Little more care is needed while handling as it has Glass tubes. Again it's unique offering & tubes makes music more enjoyable.
CONS-
1. Charging time ( it will get solve by software updates in future, Brand has co
nfirmed it in their post)
2. Only one colour option is available from Brand.
3. Some settings currently not present, Brand may add in future updates ( DSD gain Compensation, PEQ, MSEB, Night light short cut in quick pannel)
CONCLUSION-
a. Highly recommend those who want detailed & immersive experience.
b. THREE IN ONE- One DAP but three modes, all three sounds differently. One mode Transistor (without Tubes) and two Tube modes (Triode & Ultra- linear).

Sterdy & beautiful cable. I am using it with Hidiz MP145 Planner Magnetic IEM. It add details to music over stock cable. Makes all aspect of sound quality better.

I am writing review after One month regularly uses with my two DAP - Shanling M8t, Hiby R4.
POSITIVES-
1. Best Soundstage
2. Balanced sound
3. Musical & Makes music more enjoyable to ears.
4. No fatigue despite of metal construct.
5. Weight distribution is really good.
6. Largest Magnetic planner in the Category.
7. Details & instruments separation at best.
CONS-
1. Small ears may face challenge. Plz contact team ATS before purchase. Normal ear size, No issues with fit & long usage.
2. Stock cable is good but doesn't suit this IEM.
I am using this with Divinus Auram cable, which goes really well with this by appearance as well as by performance.
CONCLUSION-
1. Very very happy with the purchase. It's my main IEM in daily music journey.
2. My suggestion is Music enthusiast must have atleast one 'Planner Magnetic IEM', believe me I found that the the songs which I am listening since decades are sounding differently with some more details with this IEM.

The KZ Castor is an excellent choice for budget audiophiles. It delivers superb sound quality that rivals much more expensive headphones, with clear highs, rich mids, and deep bass. The build quality is solid, offering both durability and comfort for long listening sessions. At its price, it’s a fantastic value, outperforming many premium options. Highly recommended!

i think it's a great choice for someone who's just starting with the "iem" audiophile thing and it sounds good pretty good for the price range, it's sound clear and crisp, the bass is a little on the lower side but nonetheless great product if you are just starting, oh and yes the delivery was fast got it in a day.

Delivery was fast and item received was in good condition

Lets get to the point, its the best budget IEM!
I have been in the IEM space for more than 6 months and I was looking for a daily driver that can handle rough use, and then Pritam Sir suggested me 7Hz G1. And it failed to disappoint me!
A nice high quality well built iem, with one of the best ergonomic design, and a proper sound isolation with tons of tip to choose from.
The iem is well tuned with proper instrument seperation and clarity, warm tuning with perfect bass and excellent soundstage compared to other budget IEMs.
If you are new to yo IEM and want to buy your first IEM, blindly go with this! Trust me you would not regret! For 3.2k, its a steal deal!
(Pro Tip: Always listen to Pritam Sir's suggestions. He is the G.O.A.T)

We had an amazing experience at The Audio Store. Pritam, the shop expert, was incredibly helpful and knowledgeable. He patiently guided us through the world of in-ear monitors, explaining all the details and helping us understand what would work best for our band, Rhythm Freak. He suggested options that perfectly matched both our budget and our musical needs, making sure we got the best value without compromising on quality. Thanks to his expertise, we walked out confident and satisfied with our purchase. Highly recommend this store to any musician looking for top-notch gear and excellent service
