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.

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.

from 3749 reviewsI carry the following items in my office bag.
1. Fiio BTR7
2. Fiio BTR7‘s type-C to type-C cable
3. Fiio BTR7‘s type-C to lightning cable
4. A 4.4mm (F) to 3.5mm (M) converter
5. Hifiman RE400
6. Type-C to 3.5mm dongle
7. Lightning to 3.5mm dongle
See the attached pictures. Earlier, I used to carry these 7 items in 2 separate cases. With this case coming in at just Rs. 250/-, I have now perfectly fit all these 7 items into one case. It’s made my life easier as i no longer have to carry and pack-unpack two separate cases each time.
I also love the fact that this case fits the Fiio BTR7 like a glove.
For me, this case has the perfect length, breadth, and more importantly width.
The case’s in-hand feel is also very good and it’s zip is super smooth.
200% recommended.
The earphones obviously are great and I just hoped to get original product as I’m ordering for first time in audio store. And the product quality is super and packaging also protects damage, I like it, I would shop at audio store to get any top branded quality product
Exactly what I was looking for my iPhone 13 Mini.
Official Apple dongle works but too thin cabled tangly one.
This one is far better form-factor & music quality wise!
About The Audio Store
==================
I made 2 purchases so far. Order to delivery experiences have been so smooth, fast and efficient.
Keep up the excellent performance guys!
I bought Audio Ehhiku before AP5 and my only question to Pritam/TAS was, is there another set that can match or beat Ehhiku's sonic brilliance. Pritam recommended AP5 as a worthy side grade to Ehhiku. And AP5's lush, relaxed and premium tonality totally justifies this set's claim as one of the best bargain from a price to performance ratio in the 20 k price point. After significant burn-in, AP5 shines like a Diamond in the sky. Thanks Pritam and TAS for recommending this set. Cheers!!
I loved this cable. This was the best one available in the least price. The cable quality is supreme and order arrived on time as well.
This is my first order from the audiostore and my trust went up.
I've always enjoyed the hallmark ESS sound - resolution and instrument separation - and own a number of portable as well as desktop DACs based on various ESS chips. The RAW MDA-1 maintains that tradition but has even better imaging and soundstage IMHO. True, the sound signature of a DAC does not depend on the chip alone; the output stage design also plays a big part - and SMSL's expertise is evident here, just like in their AKM-based offerings like the Sanskrit MKII or more recently - the SU-1. Of the many albums that I used for initial impressions - want to specifically mention one - Dave Brubeck Live With The LSO. I was able to make out even the more recessed instruments and the sound was distinctly holographic - I could pinpoint location of instruments and the soundstage depth was amazing! Extremely happy with the purchase and thanks to TAS for bringing this to India so soon!
I must recommend this DAC to any alternatives out there with 3.5mm Connector.
Reason: This is very underrated DAC , it has USB audio Class 2.0, who are using UAPP ( Usb audio player pro) they will benefit from this and knows how the sound quality differs from 1.0. And only the DAC with 70mW output power this is huge in this price range. What else need more than this ? Just go for it.
Well-made versatile (balanced, single ended termination) IEM cable. In picture it may look stiff due to nylon sheathing, but in reality it is very soft and flexible cable. DUNU craftmanship on this cable is commendable.
Great iems , recommended for gaming and heavy bass music ....
For the price at these iem are you in for a party in your head. Better to use them with a DAC as more power they get the better they sound. Sound quality is👌, better than normal earphones. Great for bass heads. Also thanks to the audio store for such quick order processing , got me iems in 1 day and gift wrap (which i did not ask for or expect) kudos to them 👏!
I've been using this eartips for quite sometime now and I've been using this with the OPPO Enco X2 and I really love the fit and comfort this offers.
Plz send update the software for earbuds & more EQ mode
I am using it to connect my 4.4 mm ended cable of my IEM to my Bluetooth dac. Sound is good.
These tips saved the Final Audio A5000 for me! The overly sharp edges on most female and some male vocals, the harsh-sounding treble, and the not-so-rounded nature of sound coming out of the A5000 vanished the moment I put these tips on. I also used this with FiiO FD5, Dunu Titan S, and Meze Alba to have a nice well-rounded sound. That's what it does - it makes sound well-rounded so that the song or music that you are listening to becomes coherent across the frequency range. Perhaps the most important thing about the well-rounded sound that it provides is that you can enjoy the entire scale in your IEMs, from the lowest to the highest. In the case of the A5000, it sacrificed a bit of soundstage but at the same time provided tight and rumbly bass, natural midtones, as well as refined treble. I am surprised by the capability of these tips! And that affordable price tag is the icing on the cake! After becoming an audiophile almost a decade ago, I finally learned how to roll tips - thanks to the folks at Dunu! I would highly recommend these tips to everyone.
Smooth Sub-bass and yet neutral sounding.
