Know before you buy
The EST112 uses three different driver types to cover the full frequency range: a 13.5mm dynamic driver for deep, impactful bass, a Knowles balanced armature for clear mids, and two Sonion electrostatic drivers for smooth, extended treble. This combination ensures that no single driver is pushed beyond its comfort zone, resulting in a balanced and highly detailed sound.
The included cable features a swappable termination end, allowing you to easily switch between 3.5mm single-ended, 2.5mm balanced, and 4.4mm balanced plugs. You simply pull the plug off the cable and snap on the one that matches your source device, eliminating the need for bulky adapters.
Yes, the shells are crafted from a lightweight aluminum alloy, which keeps the weight manageable despite the complex internal driver array. The ergonomic shape is designed to sit securely in the ear, making them suitable for extended periods of use without causing fatigue.
With an impedance of 10Ω and a sensitivity of 110dB, these monitors are quite efficient and can be driven easily by most smartphones or standard dongle DACs. While a dedicated amplifier can help extract the absolute best performance, it is not strictly necessary to achieve a high-quality sound.
The EST112 offers a relaxing yet resolving sound profile. It avoids being overly aggressive or sharp, instead providing a rich, textured low end and a refined, airy treble that makes it well-suited for long-term listening across various genres.
Yes, the EST112 uses a standard detachable cable connection. If you ever need to replace the cable or prefer to use a custom aftermarket one, you can easily swap it out without needing any special tools.
