A pair of headphones with a replaceable cable has many benefits, and one of them is if the connecting cable has a problem, it doesn’t mean that you have to buy a new one. If the connecting cable gets pulled or damaged, you can replace it and keep using your good-old headphones or IEMs. This way, your headphones will be protected and will last longer. With the advancements in cable manufacturing, you now get a variety of replacement cables with various termination options, lengths and quality.

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 Nio is the latest universal In-Ear Monitor from the brand and aims to present an effortlessly smooth sound signature together with the highly technical sound. Nio features a 9 mm dynamic driver for lows, an array of six balanced armatures for mids, a high-mid BA and a single tia high driver. Now, with the introduction of Nio, 64 Audio has taken advantage of the hybrid array and further pushed the envelope of innovation in sound and design. Nio combines proprietary drivers, LID technology and a new electronic crossover network to deliver an exceptional listening experience.

The 64 Audio Nio features exclusive technologies that challenge traditional in-ear monitor designs to give you the best listening experience. The Nio 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. Nio features the tia driver and the tia single-bore design. 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 Nio consists of a 9mm dynamic driver and 8 balanced armature drivers that work in harmony with each other. With a sound signature characterised by extended lows and a rich 3-dimensional soundstage, Nio’s smooth treble and natural warmth 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, Nio’s TIA technology reduces unwanted resonance and distortion by allowing the 9mm Dynamic Driver and TIA High Driver 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 Nio to achieve a frequency response of 10Hz - 20,000kHz and a sensitivity of 105 dB/mW. The impedance of the Nio 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. 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 Nio makes use of exclusive technologies to push the performance tenfolds. One such technology embedded in the Nio is the LID (Linear Impedance Design) circuit. LID, or Linear Impedance Design, enables a consistent, reliable sound regardless of the source. This proprietary circuit corrects the non-linear impedances of the drivers, restoring proper interaction with the source device and preserving the desired sound signature. Varying source amplifier output impedance in devices like smartphones, body packs, DAC/amps, and DAPs typically results in varying frequency responses across them, depending on the increase in resistance. Restoring proper interaction with the source and preserving the desired sound signature enables a reliable sound. Whether you're a musician plugging into gear at different gigs or studios or an audiophile listening from low-impedance sources, LID ensures your IEMs present the desired sound signature.
