64 Audio is a US company from Vancouver, Washington, focused on designing and manufacturing high-quality custom and universal in-ears. With future-oriented innovations such as tia, apex, and LID, the premium in-ear monitors included in the range of 64 Audio outperform their traditional counterparts. The 64 Audio Fourte is the latest universal In-Ear Monitor from the brand and showcases the pinnacle of in-ear monitor technology. Fourte takes full advantage of the technology from 64 audio in designing world-class in-ear monitors. Fourte boasts the most accurate sound and a wide soundstage of any in-ear monitor, making it the perfect choice for audiophiles seeking detailed, lifelike audio, and three-dimensional sound. Fourte features 1 dynamic driver for lows, a TIA balanced armature for mids, a balanced armature driver for the high-mids and a TIA Balanced armature for the highs. The Fourte is engineered for audiophiles seeking a clean, laid back, 3D sound in any genre.



The 64 Audio Fourte features exclusive technologies that challenge traditional in-ear monitor designs to give you the best listening experience. The Fourte features a driver array which offers a three-dimensional high-resolution sound thanks to the proprietary TIA technology and the accompanying TIA single-bore design. Tubeless In-Ear Audio (TIA) is a patented IEM design methodology aiming to reduce unwanted resonance and distortion for a transparent and lifelike sound. The TIA system has three elements including an open TIA balanced armature drivers, TIA single-bore design, and TIA acoustic chambers. Fourte utilises the complete Tia system; its three drivers radiate freely into the Tia bore with no obstructions to the drivers. The TIA driver is an open balanced armature speaker designed for realistic resolution and transparency. By modifying a balanced armature, the diaphragm becomes completely unobstructed, reducing resonance in the IEM and allowing sound to travel more naturally to the ear. The TIA Single Bore has a considerable advancement in eliminating unwanted tube resonance. The large bore serves as a sound-shaping chamber and aids the TIA high driver in delivering a linear and coherent frequency response. The short sound path provides remarkable high-frequency extension and smoothness. The bore also allows for easier maintenance.



The team at 64 Audio have pushed the boundaries of how a hybrid driver array manages to achieve a full and engaging audio reproduction. 64 Audio embeds proprietary TIA technology BA drivers and a dynamic driver that are elevated in their functioning and eliminate the issues faced with traditional hybrid configuration. The driver configuration for the Fourte consists of 1 dynamic driver and 3 precision balanced armature drivers that work in harmony with each other. With a sound signature characterised by extended lows and a rich 3-dimensional soundstage, Fourte's accurate sound and a wide soundstage will provide hours of enjoyable listening for all genres of music. Rather than constricting the sound of the drivers by fitting a tube onto them, Fourte’S TIA technology reduces unwanted resonance and distortion by allowing the drivers to radiate freely into the single large TIA bore with no obstructions to the front of the drivers. These drivers are managed with an integrated 4-way passive crossover and allow the Fourte to achieve a frequency response of 5Hz - 22,000kHz and a sensitivity of 114 dB/mW. The impedance of the Fourte is also nominal and can pair with a variety of devices.



64 Audio integrates proprietary modular Apex technology for a fatigue-free sound experience and adjustable ambience isolation. Air 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. Apex is integrated into Fourte down to where the shell is milled, offering similar pressure release and isolation to the m20 module. This venting alleviates listener fatigue and allows for a much more realistic soundstage. When you seal a miniature speaker in an ear canal, the air inside becomes trapped. Apex relieves this air pressure, allowing the eardrum to move naturally, so you can comfortably listen longer. Apex technology also extends the soundstage by allowing air to move freely and provides a more natural listening experience. It also preserves bass frequencies and helps the listener distinguish individual instruments. Apex also lowers decibel levels while presenting the clarity of the sounds around you, so artists on stage can connect with their audience while protecting their hearing.



64 Audio are well known amongst the audiophile community and even musicians for offering highly considerate and detailed in-ears. Every aspect of the build is carefully thought through and serves a purpose at large. Just like the internal architecture that is expertly engineered, the exterior of the 64 Audio Fourte is painstakingly designed with the best materials and techniques. Fourte showcases a highly artistic design which adds some visual excitement. Fourte exudes a modern design which is highly practical with durable construction. Each ergonomic shell is machined out of a solid piece of aluminium and finished with a striking copper patina faceplate. The Fourté comes with much-needed accessories to get you started right out of the box. You get a 64 Audio premium leather case to store your Fourte when not in use. You also get a variety of TrueFidelity foam and silicone earpieces, each in sizes S, M and L, and a 48” detachable premium cable with a 3.5 mm mini-jack connector.
