Know before you buy
The Nio combines a 9mm dynamic driver for deep, impactful bass with eight balanced armature drivers to handle mids and highs. This hybrid setup allows the headphones to deliver a rich, full-bodied sound that balances punchy low-end performance with the clarity and detail of high-end balanced armatures.
The Apex modules allow you to tune the sound signature and isolation levels by venting internal air pressure. By swapping between the mX, m15, and m20 modules, you can adjust the bass response and the level of external noise isolation to better suit your environment or personal preference.
Yes, thanks to the Linear Impedance Design (LID). This technology ensures that the Nio maintains a consistent frequency response regardless of the output impedance of your source device, preventing the sound signature from shifting when you move from a phone to a dedicated high-end amplifier.
The patented tia (Tubeless In-Ear Audio) system removes the need for sound tubes and dampers typically found in balanced armature designs. By eliminating these physical barriers, the system reduces resonance and distortion, resulting in a more transparent, lifelike, and open soundstage.
The Nio is designed for comfort, featuring an ergonomic shell machined from solid aluminum and the Apex vent system. The vent relieves air pressure in the ear canal, which significantly reduces listener fatigue during extended sessions compared to traditional sealed in-ear monitors.
No, each pair of Nio monitors is unique. Because the faceplates are crafted from natural abalone, the patterns and color variations will differ from unit to unit, ensuring that your specific pair has a one-of-a-kind aesthetic.
