Fir Audio

The Radon 6 is FIR Audio’s fifth-anniversary celebratory earphone model, limited to 300 production units world-wide. Radon 6 sums up the best of Fir's recent work to Twister6. It made Headfonia's Recommended Buys list. Headfonics say it "works wonderfully well with almost everything, especially if you want an open midrange with excellent levels of detail". It's highly recommended by Ear Fidelity who tell you to "buy the Radon 6 while you still can"! Indeed, FiR Audio applied everything they learnt from the Frontier Series and mindfully retuned their popular six-driver platform to arrive at a leaner, lighter, and more detail-oriented sound signature. Rn6 features all of their proprietary technologies such as Kinetic Bass, ATOM Venting, Open Acoustics, and Rigid Technologies – truly a celebration of who they've become. [See Product Desc.

The tri-brid system consists of tubeless balanced armature Open Drivers, an ultra-high electrostatic tweeter, and a dynamic driver with the revolutionary Kinetic Bass technology – all working in perfect harmony. Fir Audio's Kinetic Bass technology features a 10mm dynamic driver that is open and ported in an optimised manner directly facing the outside of the IEM shell, allowing Radon 6 to transmit 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. Higher up, Radon 6's open drivers use no sound tubes and radiate sound directly into a 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. Radon 6's sound reactor is a chamber which shapes the sound that comes directly from the open drivers. Fir's sound reactor uses natural acoustics to shape the sound instead of dampers and filters which are found in most traditional IEMs.  And Fir's 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, without harshness, from this flagship. View Fir Audio's other releases here, or our other earphones here.

FIR Audio introduce Electron 12 (e12), a groundbreaking earphone that challenges expectations through the innovative SwapX technology. Twister6 found these single dynamic drivers a positive surprise! Seamlessly switch faceplate designs to achieve a personalised aesthetic, and experience a refined design housing a robust 12mm electro-dynamic driver equipped with Tactile Bass Technology for an immersive audio journey. Meticulously crafted for precision and durability, the e12's proprietary Tactile Bass Technology maximises the solid shell, creating a textured low end. [See Product Desc. For More] The intricately coupled 12mm dynamic driver within the IEM chassis serves as a secondary transducer for lower frequencies, providing a deeper and more resonant bass that elevates your listening experience. Taking it a step further, FIR Audio's exclusive Tactile Bass Technology utilises the entire solid shell, allowing the bass to reverberate for a tactile and textured feel in the low end. Unlike conventional IEMs that create air pressure in a sealed ear canal, FIR Audio's innovative venting system maintains your ear drums in their natural, relaxed position. Bid farewell to listener fatigue and embrace extended, comfortable listening sessions. The modular shell design, with the primary faceplate securely attached by screws, optimises efficiency and guarantees long-term serviceability.  FIR's pioneering SwapX technology not only facilitates effortless faceplate design changes for a personalised look but also features a modular shell design. The faceplate assembly, securely fastened with screws, enhances efficiency and serviceability, ensuring your investment withstands the test of time. Additionally, the e12 boasts the exclusive ATOM Venting system for an expanded soundstage and an exquisite 8-braid, pure silver oxygen-free cable with copper shielding. This delivers both style and sophistication, enhancing your audio journey. Check out FIR Audio's other releases here, or view our other IEMs here.
