Know before you buy
The 18 balanced armature drivers allow for a highly specialized frequency distribution, with dedicated drivers for lows, mids, and highs. This configuration ensures exceptional clarity and separation, allowing you to hear subtle details in a mix that standard earphones might miss.
Linear Impedance Design (LID) ensures that the A18s maintain a consistent sound signature regardless of the output source. Whether you are plugging into a high-end studio console or a portable interface, the frequency response remains stable and accurate.
These modules control the amount of passive noise isolation and bass response. The m20 module provides up to -20dB of isolation for maximum noise reduction, while the m15 module offers -15dB of isolation, which typically results in a slightly more open soundstage and reduced pressure.
Yes, the A18s are designed for comfort during extended use. The Apex venting system relieves air pressure in the ear canal, which significantly reduces listener fatigue compared to traditional sealed in-ear monitors.
The tubeless in-ear audio (tia) design removes the need for sound-altering acoustic tubes and dampers. By allowing the drivers to fire directly into the ear canal, it produces a more transparent, lifelike, and open sound profile.
With an impedance of 8Ω and a sensitivity of 106 dB/mW, the A18s are relatively easy to drive. While they will work with most standard headphone jacks, using a high-quality dedicated amplifier or interface will ensure you get the cleanest signal and best performance.
