Description
5-driver portable sound just reached a higher standard with the FiR Audio Krypton 5. This cutting-edge in-ear monitor features high-quality acoustic technology that handles each note, instrument and vocals with delicacy and care. With impactful bass and crystal-clear sound, enjoy audiophile-grade audio today.
For Outstanding Performances
Experience outstanding clarity with the FiR Audio Krypton 5. This IEM features high-end technical expertise that offers a textured presentation with incredible instrument separation. The machined aluminium shell with a sapphire glass faceplate encompasses 4 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 Krypton 5 comes in Universal-Fit and Custom-Fit models too.
Feel the Bass
The FiR Audio Krypton 5 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 Krypton 5 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 Krypton 5 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.

This iem is very versatile in some songs/music it may sounds as very bassy but in other it sounds very balanced and thick sounding.
Sub bass is so great and surrounding when listening to Interstellar - mountains theme, the sub bass is just so big and surrounding, All GOT music sounds great with very good depth and details.
For female vocals its not very forward but not very recessed either but sound very detailed and male vocals sounds great and really very detailed and seperated from rest of the music.
Imaging is fantastic with good depth it feels 3d and very well seperation.
Fitting is fantastic i used for hours and never felt any pain and with variation i start feeling pain after an hour never felt any discomfort or pain with kr5 only issue is the part where the wire connects to iem that is the only issue with fitting.
Overall great sounding iem, thick sounding but with good details and really great imaging.
Thankyou The Audio Store for great support.

We appreciate your feedback and are always here to provide great support for our customers. Enjoy your music!
Excellent layering delivered with kinetic bass on a wide sound stage. 👌.
Thank you for your review! We're glad to hear you're enjoying the FiR Audio Krypton 5 IEMs. We're excited to see what you think of our bass and sound stage when you use them for a longer period of time.
I wanted to write this review after spending some valuable time with the KR5. I've spent the last eight months researching this product, and here's what I think about it:
I couldn't believe my ears when I heard this product for the first time (after 100 hours of burn-in). The reaction is utterly silent and speechless. The impact, clarity, and—most importantly—the sensation of hearing the bass in your mind as well as in your ears cannot be adequately described using my vernacular. This is a sensation that can only be felt, not explained. I've heard a number of IEMs, but after hearing this, I don't believe I'll be able to appreciate the bass on any of them.
My collection includes practically all models from 64 Audio, Sennheiser, Campfire Audio, Moondrop, Final Audio, and the majority of the top-rated Chi-Fi IEMs. I doubt I'll ever appreciate the bass on any of them anymore.
At first, it may feel like there is too much bass, but the more time you spend on this product, the more you realise that this jewel shines in all aspect of hi-fidelity music.
Oh my goodness, I was shocked to experience a soundscape that rivalled many good quality open-back headphones. There are ver few IEMs that can trade blows with KR5. The soundstage is displayed in 3D rather than with a broad left-right separation. The same is true for layering and retrieving details.
Finally, I'd want to thank Pritam for recommending this product to me. My advice to my peers is that if he advises anything, buy it without hesitation; you won't be sorry, because he doesn't generally recommend a lot of items. As is customary, the package and shipping are both on time and flawless.
Thanks for the review! We're glad that you like FiR Audio Kr5.

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.

Sounds exactly like the Salnotes Zero with a bit more bass. Has that same Harman curve with upper midrange bump and reduced lower mids making male vocals sound thin. Good resolution/detail and treble is perfectly done. Fit is good and I like that these are very light.

I have own onix aplha as a dac and this is definitely a upgrade in that regards
