FiR Audio Krypton 5 IEM

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.
