Description
Experience an extremely rich audio performance with the FiR Audio Neon 4. This gorgeous IEM uses the latest IEM tech to deliver spectacular audio with powerful bass, lush mids and extended treble.
Smooth, Creamy & Rich
Enjoy smooth, creamy, high-res audio with the FiR Audio Neon 4. It offers lush upper mids and treble along with an incredible soundstage and positioning thanks to its ATOM XS module. Powerful and detailed bass enhances the listening experience for an immersive sound. The machined aluminium shell with a sapphire glass faceplate encompasses 3 balanced armature drivers and a 10mm dynamic driver.
Deeper than the Ocean
Regular IEMs usually lack depth as they deliver only half the sound. In a natural open-ear environment, the sound is heard in two ways - air conduction and bone conduction. Air conduction is the sound you hear with your eardrums. Bone conduction is the conduction of sound through the bones in your head as it reaches the inner ear (cochlea). Hybrid conduction mixes both. Like the rest of the Frontier Series, the Neon 4 comes in Universal-Fit and Custom-Fit models too.
Feel the Bass
The FiR Audio Neon 4 features cutting-edge Kinetic Bass technology. An open and ported 10mm dynamic driver is optimised to face the IEM shell’s exterior allowing lower frequencies to be transmitted directly to the ear cartilage and surrounding area. These frequencies are converted to kinetic energy that reaches the inner ear via bone conduction. This enhances the bass with an immersive audio experience and off-the-charts bass extension.
Open Acoustics System for an Open Sound
Traditional IEMs use a sound tube with the drivers to carry the sound to the canal stem. However, this creates unwanted resonances and a closed-in, stuffy sound. The FiR Audio Neon 4 is designed with an Open Acoustics System comprising Open Drivers, a Sound Reactor and Sound Reflector for an incredible audio experience.
Goodbye Tubes, Hello High-End Acoustics
By not using sound tubes, the Open Drivers allow sound to flow directly into the Sound Reactor and in turn the ear canal. This ensures a wider soundstage with clear, natural audio. The Sound Reactor chamber shapes the sound coming from the drivers using natural acoustics instead of the dampers and filters used in traditional IEMs. The Sound Reflector directs the high frequencies into the ear canal for extended, smooth and airy treble.
No Pressure, Just Music
An Air Transferring Open Module reduces the pressure that builds up in a sealed ear canal. This reduces fatigue for long listening sessions. The ATOM Venting Technology is instrumental in protecting your hearing while being easy to swap for various levels of bass and noise isolation.
Flexes a Rigid Build
The Neon 4 uses cutting-edge proprietary Rigid technologies for better reliability and durability. The 2-pin connector has been tested for 1,000 seamless connections. It easily fits into the quadrant socket design on the 3D printed shell that’s 20% thicker than the industry average for better durability. A snap screen i.e. an acoustically transparent mesh screen prevents debris from entering the canal stem.

Disclaimer: I prefer mid centric tuning with slight elevation in bass. 65% of my music library is vocal centric.
This is one of the best iem in my collection, this one was a shocker as I remember asking Pritam Bhai what iem would be detailed and have that good amount of slam he gave me two options ie900 and NE4 based on my preference but highly suggested to buy NE4 so I did. That all aside the iem can easily pass as a piece of art, not only that but the solid build quality is a statement in itself. The unboxing experience was also quite a premium one. Especially the included patch and letter makes you feel that you are now part of an elite club and the patch being its insignia.
The music part:
The iems follow a unique W shaped tuning that is quite un common in the current market where everyone is trying to make variants of the same sound signature. It sometimes feels that once you have heard one iem you have heard them all. Amass all the competition these iems do shine differently mainly due to their proprietary technology that is something never heard before.
Bass: Man, what can I say about bass this is one of the best bass I have ever heard in an iem. It feels like there is a subwoofer in your ears. you gotta hear it to believe it. As it has a mid-bass focused tuning so, the sub-bass section doesn't hit like crazy but man when the mid bass comes in it comes hard. Also, it’s not very bloaty or out of control there is a good amount of texture to it. Drums and bass guitars sound very natural and organic.
Mids: The iem’s late midrange dip around 700Hz makes it perfect for songs that are very lively, but due to this it can seem that vocals sometimes take a backseat. Not only that but guitars and male vocals sound great. Though male vocals are presented a bit warm because the pinna compensation starts a bit early compared to other iems in my collection. There is a dip at 3k Hz making female vocals a bit tamer. This all makes for a relaxed listening experience.
Treble: These iems have nice treble presence. The high hats and cymbals sound quite nice and not inorganic at all. There is also good amount of air in them making them sound surreal.
Tech: They are no slouch in the tech aspect. One of the largest stage I have heard in my collection. Also, they do seem more holographic than my Um mest mk2. The microdetails are quite prominent in my music library. Man, to be honest I have heard things in my music that I didn’t even know existed.
Comparisons:
unlike regular comparison section I will like to just make a brief ranking section (of all Totl iems I own) in each section and then give my reason for it.
Bass: Ne4>Mest Mk2>U12t>ExE Gaea>CA ARA. I mean after reading the bass section I don’t think I need to explain it any further.
Mids: ExE Gaea>U12T=NE4>CA ARA>Mest mk2. I do prefer a bit of lean midrange as for me it brings out more of that texture in vocals. The NE4 mids are similarly tuned as u12t’s but both the peaks are a bit early making them warmer and quite relaxed.
Treble: ExE Gaea > NE4 > CA ARA > U12T> Mest Mk2 . The treble presentation is quite good in this iem but not as good as Gaea due to its tuning. But, Gaea sometimes feels a bit harsh to quite a lot of people due to this. The NE4 treble feels perfect.
Conclusion: These Iem have a very steep asking price. But if you ask me, I would definitely say that these are well worth it. One cannot listen to these crazy technical and lean sounding iems for extended amount of time it’s quite fatiguing. Whereas, that is what is unique about this set its quite non fatiguing not only that but it is fit and comfort is so good that it makes you feel like they aren’t in your ears at all. All these factors lead them to become my daily drivers.

Let customers speak for us

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

Sound quality ausom but not for base lover's

Top notch earphone Mike quality 🔥.gaming, music etc highly recommend ❤️🎧

I believe this is the best tws under 10000 rupees also it is an iem

Thank you audio store. The sound is amazing. It was delivered within time and product was perfect.

Very detail iem for the price not bass heavy

It is compact and yet have a good punch to the output it gives, the packaging was very impressive for the price.

Twilight from Soft Ears seems to me like a benchmark for single DD IEMs. The solid metal craftsmanship is commendable and when it comes to the sound, tonality, song signature and quality is presently benchmark for Single DD IEMs, may be rivalled by the Elder turii ti, which cost 3x of this.

I would really recommend these. I previously used KZ Castor, but these IEMs are a major upgrade. The sound division is really good. The only issues are low bass and high treble. If you want a more balanced or v shape, it is better to use an equaliser. I am using these with Fiio K1 and Audiocular X Tiandirenhe CS-PRO DACs. Both give a nice output.
I don't know if this is specific to Apple Music or IE 200, but when I push the music through an equaliser, I hear a crackling sound (only on hi-res, 24-bit/192 kHz). I will maybe test more on this and will update the review.
Finally, I would recommend it. These IEMs are worth the buck.

One of the best dac amp in budget category, it gives balance output that going well with my performer 8.

It's an interesting product. I like all the tip options in this pack. It's a good beginner pack to know how each tip material can affect the sound quality. All the tip material & quality are good. The silicone tips & foam tips in the pack are good, like those stock tips we get with IEM. But the surprising tips are the latex tip & the hybrid foam tip. Although the latex tip feels a little rubbery in feel & is a dust magnet, but it's very comfortable, provides a good seal and does enhance bass & treble response slightly. And for the hybrid tip, it's like best of both worlds. It gives the comfort of a silicone tip as well as provides the seal of a foam tip. I'm not a big fan of foam tip in general because of how they feel in ear & it's very difficult to put them in the ear, but these hybrid tips removed all those problems for me.

This is one of the best modular cables I have ever seen in this price range. Microphonic is there as the nylon type of material is used for wrapping the cable. But microphonic is very minimal compared to other similar cable I have used. But, once the music starts playing, the microphonic would be gone. connector quality is very premium, on both the 3.5 / 4.4 termination as well as at 2-pin connector end. I love how easy is to replace the 3.5 & 4.4 end. It's highly recommended if you are looking for any premium modular cable on budget. It's one of my favorite modular cables along with the Moondrop aria 2's stock modular cable.
