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.

Phenomenal Sub bass with great imaging

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.

Long term review for KR5... a new benchmark

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.
