7Hz Salnotes Zero HiFi 10mm Dynamic Driver in-Ear Earphone IEM with Metal Composite Diaphragm Stainless Steel Faceplate Detachable 2Pin OFC Cable (Black, Without Mic)

The 7Hz Salnotes Zero directly competes with the similarly priced Moondrop Chu. Overall, the Zero and the Chu are neck-and-neck in terms of sound quality. They each have certain strengths and weaknesses compared to the other, but both put other options at the price point to shame. The two IEMs also make different trade-offs in terms of build and accessories. While buyers will need to weigh which characteristics they value more in choosing between the two, both are solid buys for $20. SOURCES: I have used the 7Hz Salnotes Zero with the following sources: Qudelix 5K Hidizs S9 E1DA 9038D PACKAGING AND ACCESSORIES: The 7Hz Salnotes Zero comes in a small white cardboard box. The packaging features pictures of the Zero on the front and back covers. In addition to the IEMs and detachable 2-pin cable, the Zero includes six pairs of silicone eartips in several varieties. These appear to be the same varieties described in my Dioko review: The red, blue, and orange pairs are squatter and more conical in shape and feature wider nozzles. The light blue and yellow eartips are more round with narrower nozzles. The pink pair is also round but with wider nozzles than the other round eartips. The pair of eartips resembling AZLA SednaEarfit Crystal eartips included with the Dioko is not included with the Zero. The Zero includes a product information card and a user manual written in English and Chinese, as well as a small velcro tie. The Zero does not include a carry pouch or case. BUILD QUALITY AND DESIGN: The 7Hz Salnotes Zero has a two-part plastic chassis with a stainless steel faceplate. The faceplates have a jagged, angular outline. “SAL♪NOTES ZERO” is laser-etched at the base of each faceplate. There is a small circular rivet at the top of each faceplate. The faceplates have developed minor scratches over the course of my review. There is a small circular recession on the inside of each chassis with an embossed “L” or “R” indicator. There is also a pinprick vent at the base of the nozzle. The nozzles have the same metal and paper nozzle covers as the Dioko, and have extruded lips to secure eartips. The 2-pin connectors are very snug and quite difficult to remove. The 2-pin connectors fit flush with the surface of the IEM housing body. Each 2-pin entry site is marked with a small red dot to indicate polarity. The included 2-pin cable has two strands that are joined in parallel below the Y-split. The cable uses a mix of metal and dark plastic hardware. The cable jack has a straight form factor. “SAL♪NOTES” is printed in white along the length of the jack housing. There is strain relief above the jack housing but none at the Y-split. The cable has pre-formed earguides without memory wire and a rubber chin-adjustment choker. The curved 2-pin housings have faintly raised “L” and “R” markings. The cable is mildly microphonic. COMFORT, FIT, AND ISOLATION: The 7Hz Salnotes Zero is intended to be worn cable-up. The earpieces have a shallow insertion depth. I found the Zero to be very comfortable. However, secureness of fit is below average and the housings required occasional readjustment with most eartips I tried the Zero with. Isolation is fairly poor. There is mild driver flex. SOUND AND COMPARISON TO THE MOONDROP CHU: The 7Hz Salnotes Zero is tuned very similarly to the Moondrop Chu. Like the Chu, the Zero has a Harman-ish sound that emphasizes sub-bass over mid-bass, features a robust pinna gain region, and slopes downward from the pinna gain region through the upper treble. The biggest tonal difference between the Chu and the Zero is that the Zero’s pinna gain region peaks later than the Chu. The Chu’s pinna gain region is centered around 3 kHz, while the Zero’s peaks later at around 3.5 kHz. This is a subtle difference, but depending on your ear physiology, may impact which of the two IEMs vocals sound more natural with. The Zero has a twinge more measured sub-bass than the Chu, although the difference between my samples is so small that this may be a question of unit variation rather than intended tuning. Subjectively, I feel that percussion actually has a greater impact on the Chu than the Zero. The Chu also has a hair more upper treble extension than the Zero. The Zero’s sub-bass shelf is mild in its amplitude, and sub-bass extension is average. Bass articulation and resolution are both very good. The Zero’s bass is well-textured for the price but is lacking in impact. The result is a clean but underwhelming bass tuning. After hearing the Chu and now the Zero, I have come to believe that if an IEM opts for a pure sub-bass shelf, the amplitude of that shelf needs to be greater than what either of these IEMs displays. The bass does not bleed into the lower mids. The Zero’s midrange is on the cooler side. Male vocals have grit but are slightly lacking in warmth. The amount of body to male vocals is somewhere in between these two other qualities. Female vocals are slightly more forward than male vocals, though both are very intelligible. Female vocals do sound more natural on the Chu than the Zero. On the Zero, there is a hint of strain and sibilance. On the Chu, female vocals are just slightly more grounded. With that said, the Zero’s midrange clarity is astonishing for an IEM of this price. The level of presence is essentially perfect for heavy rock genres. Timbre is slightly dry but natural sounding overall. The Zero has slightly less lower treble energy than the Chu, which I prefer. Like the Chu, the Zero has a noticeable drop-off in the mid-treble which deprives cymbal hits of sparkle. While the Chu has better upper treble extension than the Zero, the Zero has slightly crisper treble transient delivery. The Chu has a larger soundstage and slightly better detail retrieval. Imaging between the two is comparable. The Zero has the best instrument separation I have heard on an IEM at this price. AMPLIFICATION REQUIREMENTS AND SOURCE PAIRING: The 7Hz Salnotes Zero does not need a powerful source to reach a usable listening volume. I did not notice hiss with any of my devices.

These were replacement for some budget AKG over ear headphones and the persons first IEM's, they certainly obliterate those. For under 20 dollars they're night and day compared to skull candy garbage you would find in most local stores for a similar price. Fairly comfortable and clear sounding, almost as good as my Moondrop Starfield's are, like 80-90% of the sound quality, maybe a bit less comfortable? Probably fixable with some after market ear tips from china for $5. There's less pronounced bass, more so at the lowest tones. Things are a bit less "detailed?" overall than my Starfields, hard to put my finger on it exactly, but I still enjoyed listening to them. Cable's fairly short at around 3-3.5 feet long, but you can buy an extension cable for like $5 with the money saved. Includes 3-4 sets of different color of tips for them, may be slightly to big for small ear canals. The cable's good, it fits snugly in the IEM's and wraps around the ears fairly nicely. The cable and the IEM's are pretty good looking on top of that. Definitely a fantastic value proposition. If you need something for kids, teenagers, tight budgets or people without the best hearing this is a good option. If you're an audiophile you probably will want something better. Are my Starfields better? Yes. Are they 5x as good? No. Really comes down to how much money you have and how picky you are about your listening experience.

This is a review of 7Hz Linsoul Zero wired in-ear earbuds ordered from Amazon within the last two weeks, at $19.55/set after a 15% discount from $23, not including sales tax. The sound quality is superb with clean presentation of base, mid-range, and treble. The earbuds produce clear and well balanced sound. The cables are not thin and the whole earbud set appears to be well built. I like the sound quality and comfortability, which deserve 5 stars in the price point of $20. I like it so much that I got two pairs of 7Hz Linsoul Zero earbuds. However, I took off one star because the manual that came with the earbuds does not show clearly how to connect the cables to the earbuds in order to obtain a comfortable and secure fit to the ears without any air gap. There are 4 ways to connect the cables to the earbuds. In the absence of clear instruction in the manual, I had to experiment and compare the 4 ways to arrive at the best way. In the past two weeks, I have ordered 4 pairs of wired in-ear earbuds, costing no more than $20, in search of the best wired earbuds for listening to classical music at this price point. I should point out that my opinions are geared toward classical music. If you listen to other genres of music, my opinions may differ from yours. Among the 4 pairs, I rank 7Hz Linsoul Zero to be the best. It beats out Sony MDREX155AP, the 2nd place (original price $30, discounted to $15). The sound produced by Sony MDREX155AP is not as clean and balanced as that by 7Hz Linsoul Zero. The cables are also thin. The 3rd place is Panasonic ErgoFit (price $9, without any discount). The sound by Panasonic ErgoFit is too thin. The cables of Panasonic ErgoFit are also the thinnest among the 4 pairs. That's not surprising because Panasonic ErgoFit is the cheapest. The 4th place is Sephia SP3060 (at a discounted price of $12). The non-twistable cables are not too thin and not too thick. The whole earbuds appear to be well built. However, I was really disappointed with the sound quality, despite the glowing reviews it got in Amazon. The thing that kills Sephia SP3060 is the blurred base. To me, Sephia SP3060 has augmented the base portion too much affecting the overall sound quality in a negative way. However, people who listen to other genres with an emphasis on base may perceive the sound produced by Sephia SP3060 differently.

Działają niby ok ale nie wiem czy tylko w mojej wersji ale mało dołu. Bassu prawie jak by nie było. Reszta mikrofon i środek ok. Poprzednia parę odesłałem ze względu na zepsuty mikrofon. Produkt nie spełnił oczekiwań. Miały grać przyzwoicie za tą cenę ale niestety nie grają.

read about them on reddit and they are great! the are also slim so you dont feel them if you sleep with them on.

Picked these up because of the raving online reviews. I like a balanced sound with even bass and treble so it suits me quite well, but this is of course, subjective. A bit concerned about the reviews about QC before purchase, but after about a year of daily use and abuse, I have not had any issues yet, so either I got lucky or the defect rate is quite low.

They are one of the best 20$ iems, very wide soundstage for a bassy headphones, deep rumbling base with a good mids and highs. Recommended for new biggner audiophiles, it will give you a taste of hi-res audio. Cons: The tips that are included basically sucks.

They're lightweight, and despite the weird shape they're very comfortable in my ears. On top of that, they sound great for a budget IEM! I personally prefer a little bit more mid-bass than these offer, but that's no fault of the product. They have great clarity and a natural soundstage for something so cheap. Moving onto accessories, the ear tips seem to be above average quality, and I like the inclusion of wide and narrow bore options, as well as the fun colours used on them. The cable on the other hand is only average... It's electrically fine, so doesn't negatively impact sound quality, but it seems to develop kinks quite easily. At least it seems quite durable, so it's not likely to die soon from tangling. It's just an annoyance. So overall, you can get better, but these are still great for travel or keeping around as spares, and would be even better with a replacement cable (they appear to be compatible with common aftermarket IEM cables).
