The Simgot ET142 are Hi-Fi hybrid in-ear monitors combining a 12.5mm planar magnetic driver with a multilayer ceramic piezoelectric driver to deliver detailed, fast and extended sound reproduction across the entire frequency range. Featuring an impedance of 14Ω ±15%, a sensitivity of 118dB/Vrms (@1kHz) and a frequency response extending from 8Hz to 40kHz, they are easy to drive with digital audio players, DAC/headphone amplifiers and smartphones. They come supplied with a premium detachable 732-strand Litz cable made from OFC copper and silver-plated OFC copper, equipped with 0.78mm 2-pin CIEM connectors and an interchangeable plug system featuring both 3.5mm single-ended and 4.4mm balanced terminations, ensuring broad compatibility with most audio sources.
The ET142 features a large 12.5mm planar magnetic driver, renowned for its lightweight and precisely controlled diaphragm. This technology delivers outstanding transient response, low distortion and exceptionally accurate micro-detail reproduction, with controlled bass, natural mids and extended highs.


To further enhance high-frequency reproduction, the planar driver is paired with a multilayer ceramic piezoelectric driver. This hybrid configuration extends the frequency response up to 40kHz while adding greater airiness, finesse and detail to the treble without compromising the overall tonal balance.
The Simgot ET142 comes with a 732-strand audiophile-grade Litz cable made from OFC copper and silver-plated OFC copper to ensure excellent conductivity and optimal signal transmission. Thanks to its detachable 0.78mm 2-pin connectors and interchangeable 3.5mm and 4.4mm plugs, it easily adapts to both single-ended and balanced audio sources.
