FiR Audio was founded in 2018 by two brothers, Bogdan and Alex Belonozhko and their friend Daniel Lifflander. Between them they have over 20 years of experience in designing and manufacturing some of the most advanced in-ear monitors while they were at 64 Audio. At FiR Audio, they are able to produce the next generation of IEM products, again pushing the boundaries of IEM technology.
In 2019 FiR Audio released the M-Series, their first line of In-Ear Monitors which gained considerable popularity from professional musicians and audiophiles all around the world. Featuring proprietary IEM technologies which all work together to provide the most natural and enjoyable listening experience. Including the ATOM venting system, Direct Aperture Acoustics, Tactile Bass, and the ultra-durable RCX connector. The M-Series showcased FiR Audio’s knowledge, expertise, and capabilities and cemented their reputation as a high-end in-ear monitor company.
Along the way, FiR Audio also tackled some of the biggest unsolved issues when it came to cleaning and maintaining in-ear monitors. This resulted in FiR Audio launching the IEM Vacs, followed later by the IEM Dryers. The perfect solution for audiophiles and monitor engineers who want to maintain their in-ears and keep them at peak performance at all times, also preventing repairs and down time.
Two years later, in 2021 FiR Audio released the Frontier Series, which includes the flagship Xenon 6, Krypton 5, and Neon 4 models. Packed with revolutionary technologies such as Kinetic Bass, a hybrid conduction technology which enables a very rich and natural bass, ATOM XS, the next generation ATOM module, Open Acoustics System, with Open Drivers that don’t use sound tubes, and Rigid Technologies that provide industry leading durability and serviceability of the IEMs. The Frontier Series comes in both Custom-Fit and Universal-Fit models.
An audiophile bassy iem which is definitely an all-rounder considering music genres. Definitely a daily use opened iem, which stands between Krypton and Xenon. This one always deliver consistently with thick and open mid range with EST influence on treble region. Definitely an all rounder bassy iem.

Sound:
Radon 6 is very fast and energetic speed in delivering the sound with perfect bass texture. The instrument separation is crystal clear, especially in mid-range which sounds open so well and accurately. For every sound node, there is an airy, emotional, and nice extension. The vocals stand outstanding and have deep emotion.
The kinetic bass technology works really well in delivering the physical bass for your ears. Bass has a strong resolution presence and is able to hear different kinds of bass textures. There is turbo speed bass for the very track you play. the energy you feel and it makes fun listening.
The most interesting of the IEM is tuning. How they made all low, mid, and highs perfectly sound great with gigantic bass. All 3 ranges sound so smooth and perfect and you are able to listen to everything in the best possible way.
Soundstage and imagining are very well in the room. Even better can it be but never feel like limited at any point in time if you have not come over from 64 Audio Fourte.
Its all-rounder IEM makes you feel relaxed with its fun sound and separation, joyful full bass, great imaging, and soundstage. Strongly recommend it if you are looking for something to end this High-end IEM game journey. It's an END GAME with this IEM.
It's impossible to get this kind of sounding IEM in the market but dont know why the Company came up with a limited Edition plan. This really works for most of the Aduiphiles' taste. Grab it when it's available :)
Thanks to Pritam and the Audio store team for bringing the Fir Audio to India and the technology for us to taste.

Just bought it and started using it with my IFI Zen Stack - feels awesome.
This was a natural pick for me, since I wanted to have a completely balanced setup for my HiFiMan Sundara.
Nothing much to add, if you want an optimal balanced setup without spending too much, then look no further.
Thanks AudioStore for being blazing fast with your delivery. I got it withing 48 hours of placing my order! Kudos.

For my HiFiMan Sundara, this is a nice quality 4.4 mm balanced cable. I am buying this for the second time, since the first one got destroyed by my kids.
If you are looking for a good quality 4.4 mm balanced cable, look no further.
Audio

This product is reached my expectation good purchase good audio signal transmission no noise at all.....thank you the audio store👍
Yes

I have used lots of TWS even high end of Samsung and Oppo worth 10K. But IEM sound signature is great! This is my second IEM. I had KZ-ZEX. It has dual driver with electrostatic. Compare with that MoonDrop Chu 2 is better clear and smooth sound signature even with single driver. I am using with Audiocular DAC cost 750. Just go with MoonDrop Chu 2 if you are music lover. Thanks.
Great packaging and quick delivery
Loved the theme of the store and the support of the customer service for every problem I faced. I would be interested in buying new things from the audio store in future.
Good Quality and got a clear case for the player.
Thank you 😊

The quality is great, I felt that the base got a bit reduced and mids and treble enhanced using the same. They look premium. The only downside is that they are slightly bulky as the cable is 16 core and sometimes you can feel it behind the ears. Overall a great cable to upgrade your entry level iems to support balanced output

After going through many websites, I came to know about this particular dac, which is purely oriented on audio amplification with dedicated chip unlike other dacs available under 2k, so ordered and received in two days, to my surprise it has significantly enhanced the audio experience on oneplus 13R, with wired earphones (redmi hi-res of 500 INR), usb type a to c adaptor really came into handy and detected as HiFi audio in my dell laptop, cherry on the cake was the pouch, I didn't expect a pouch, very happy with the purchase...

Visited thier store cum experience center it was very great place for sound lovers . Especially like their display of products in thier demo room.The Owner /Staff were cooperative and also suggested me several IEM's before i select one.

I was looking for IEM Tangzu but they were loud and bass was little low as per my ears.Owner or Associate at store suggested me Audicular i liked the sound as well as bass effect its great product.
The Sennheiser IE 200 delivers impressive value for the price. Comfort-wise, they’re lightweight and fit snugly thanks to the ergonomic design and included foam/silicone tips—great for long listening sessions. Build quality is solid despite the plastic housing, and the detachable braided cable adds durability. As for the sound signature, it’s balanced and clean—tight bass, clear mids, and smooth treble without harshness. Bonus points for the dual-tuning feature that lets you slightly tweak the sound. A fantastic entry-level choice for anyone looking to step into the audiophile world.
There sound is pretty good
