Customer Reviews
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.

Machined Aluminum Shells|Sapphire Glass Faceplate

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.

ATOM Venting
With the ATOM venting system, your ear drums can stay in their natural relaxed position and you can listen to music longer and safer without your ears getting tired. The soundstage is wider and feels more natural like an open-ear listening experience but with all the benefits of in-ear monitors. The ATOM technology comes in 4 different options which provide different levels of isolation and bass. The Frontier Series Universal-Fit models comes with the super ergonomic and easily swappable ATOM XS modules and the Custom-Fit models come with your choice of internal ATOM or the ATOM X modules which are also interchangeable.

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 drivers use no sound tubes and radiate sound directly into the Sound Reactor which allows the sound to freely flow to the ear canal. This results in a much larger soundstage and a more pure and natural listening experience.The sound reactor is a chamber which shapes the sound that comes directly from the open drivers. The sound reactor uses natural acoustics to shape the sound instead of dampers and filters which are found in most traditional IEMs. Our open high driver is located in the canal stem and features a sound reflector that directs the high frequencies into the ear canal. The results are remarkably smooth and airy highs with great extension.
