FiR Audio Krypton 5
The pinnacle of 5-driver portable sound. The Krypton 5 is a technical performer with outstanding quality and clarity. Handling each note, instrument and layer with delicacy and care. Snappy impactful bass forms the backbone to the Krypton 5’s textured presentation. Making for a crystal-clear, enjoyable audiophile IEM.
The Krypton 5 features machined aluminum shells, sapphire crystal glass faceplates, is outfitted with 4 balanced armature drivers, a 10mm dynamic driver for lows, fed into FiR Audio’s Kinetic Bass port.
Along with the rest of the Frontier Series, the Krypton 5 comes in Universal-Fit and Custom-Fit models.
Conventional In-Ear Monitors (IEMs) can often lack depth and feel because they only provide you with half the sound. When you listen to music in a natural open-ear environment, you hear sound in two ways: air conduction and bone conduction. Air conduction is sound that 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 is when you can hear with both, air conduction and bone conduction.
A bass you not only hear, but can also feel.
Kinetic Bass technology features a 10mm dynamic driver that is open and ported in an optimized manner directly facing the outside of the IEM shell. This allows low frequency sound to be transmitted directly to the ear cartilage and surrounding area. These low frequencies are converted to kinetic energy and reach the inner ear via bone conduction. This results in a more immersive sound with a bass you can feel with increased dimension and an off-the-charts low frequency extension.
Traditional in-ear monitors use a miniature speaker called a driver with a sound tube that carries the sound to the canal stem. The tube introduces unwanted resonances and results in a closed-in, stuffy sound.
The Open Acoustics System consists of three major parts: Open Drivers, Sound Reactor, and Sound Reflector.
