The strength, resilience, and bio-harmony of titanium, combined with the legendary sound of U12t, create the ultimate icon of timeless style and performance.\u003c\/p\u003e\n\u003ch3\u003eTi-6Al-4V (Tc4) Titanium\u003c\/h3\u003e\n\u003cp\u003eTi-6Al-4V (Grade 5) is the most widely used alpha beta titanium alloy, comprising ~90% Ti, 6% Aluminum, and 4% Vanadium. It offers an exceptional strength to-weight ratio, high corrosion resistance, and good bio-compatibility. Key applications include aerospace structural components, medical implants, high performance racing parts, and now, audiophile grade earphones.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0065\/4432\/6771\/files\/CABLE_Shiny.jpg?v=1774466362\" alt=\"\"\u003e\u003c\/p\u003e\n\u003ch3\u003eShielded Cable\u003c\/h3\u003e\n\u003cp\u003eThis dedicated cable, specially crafted for TWELVE Ti, completes the look for a head to toe titanium aesthetic. The four-core cross-braided cable is made from silver-plated, single-crystal copper (UP-OCC), offering outstanding noise shielding and transparent signal transmission. With a low impedance of just 0.29Ω, it maximizes electrical efficiency.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e0.78mm Non-Recessed 2-Pin\u003c\/li\u003e\n\u003cli\u003e24 AWG 4-Core Litz Cable\u003c\/li\u003e\n\u003cli\u003e99 Strands Per Core\u003c\/li\u003e\n\u003cli\u003eSilver-Plated UP-OCC Copper\u003c\/li\u003e\n\u003cli\u003e0.29 Ohms Total Impedance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003etia®\u003c\/h3\u003e\n\u003cp\u003eTubeless In-Ear Audio (tia) is a patented IEM design methodology that aims to reduce unwanted resonance and distortion for a transparent and lifelike sound signature. The tia system is comprised of three major elements: open balanced armature tia drivers, the tia single-bore design, and tia acoustic chambers. U12t features two major elements of the tia system: the tia driver and the tia single-bore design.\u003c\/p\u003e\n\u003ch3\u003eapex®\u003c\/h3\u003e\n\u003cp\u003eAir Pressure Exchange (Apex) is a patented vent that releases air pressure in a sealed ear canal all while retaining standard IEM levels of isolation; enabling musicians and music enthusiasts to listen more comfortably for longer. This venting alleviates listener fatigue and allows for a much more realistic soundstage. Apex comes in three module variations for U12t: mX, m15 and m20.\u003c\/p\u003e\n\u003ch3\u003eLID®\u003c\/h3\u003e\n\u003cp\u003eLinear Impedance Design (LID) is a patented circuit that corrects the non-linear electrical resistance of the multiple driver-sets comprising this 12 driver IEM. Varying source amplifier output impedance in devices like smartphones, body packs, DAC\/amps, and DAPs typically results in varying frequency response across them, depending on the increase in resistance. Restoring proper interaction with the source and preserving the desired sound signature enables a consistent reliable sound.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0065\/4432\/6771\/files\/Ti-Held.jpg?v=1774466362\" alt=\"\"\u003e\u003c\/p\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDriver Configuration:\u003c\/strong\u003e 1 tia High Driver, 1 High-Mid Driver, 6 Mid Drivers, 4 Low Drivers\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrequency Response:\u003c\/strong\u003e 10Hz – 20kHz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSensitivity:\u003c\/strong\u003e 108dB @1kHz @1mW\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eImpedance:\u003c\/strong\u003e 12.6Ω @1kHz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCrossover:\u003c\/strong\u003e Integrated 4-way passive crossover\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApex Isolation:\u003c\/strong\u003e -10dB to -20dB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e0.78mm 2-Pin Cables:\u003c\/strong\u003e 24 AWG 4-Core Litz Cable, 99 Strands Per Core, Silver-Plated UP-OCC Copper, 0.29 Ohms Total Impedance\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Tc4 Titanium shell, faceplate, and apex m20 module\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTechnology:\u003c\/strong\u003e apex, tia, LID\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eIncluded\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eUniversal In-Ear Monitors\u003c\/li\u003e\n\u003cli\u003eCarry Case\u003c\/li\u003e\n\u003cli\u003eTrueFidelity Foam Ear Tips (S, M, L)\u003c\/li\u003e\n\u003cli\u003eSpinFit Silicone Ear Tips (S, M, L)\u003c\/li\u003e\n\u003cli\u003eSilicone Ear Tips (S, M, L)\u003c\/li\u003e\n\u003cli\u003e3.5mm Shielded Cable\u003c\/li\u003e\n\u003cli\u003e4.4mm Balanced Shielded Cable\u003c\/li\u003e\n\u003cli\u003eShirt Clip\u003c\/li\u003e\n\u003cli\u003eCleaning Tool\u003c\/li\u003e\n\u003cli\u003eCleaning Cloth\u003c\/li\u003e\n\u003cli\u003eRound Sticker\u003c\/li\u003e\n\u003cli\u003eApex Modules (m20, m15, m12, mX)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"64 Audio","offers":[{"title":"Default Title","offer_id":50690616721641,"sku":"TWELVE Ti","price":2499.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0065\/4432\/6771\/files\/Twelve-Ti_Gallery-1_74da1dc6-3ed8-4bde-ade0-b42256022ad2.jpg?v=1774466328","url":"https:\/\/audio46.com\/products\/64-audio-twelve-ti-limited-edition-universal-in-ear-monitor","provider":"Audio46 Headphone Store","version":"1.0","type":"link"}
