SIMGOT EW300 STD In-Ear Monitors

The Simgot EW300 STD are tribrid in-ear monitors designed to deliver detailed and balanced sound reproduction through an architecture combining a 10mm dynamic driver with a ceramic composite diaphragm and dual acoustic chamber, a 6mm annular planar driver, and a ceramic piezoelectric (PZT) driver dedicated to high frequencies. This combination provides deep bass, accurate mids, and treble rich in micro-detail. The EW300 feature a 28Ω impedance (±15% at 1kHz) and a sensitivity of 121dB/Vrms at 1kHz (using the silver-plated steel nozzle with the red silicone ring), ensuring easy drivability with most digital audio players, portable DAC/headphone amplifiers, and compatible smartphones. Their frequency response extends from 8Hz to 40kHz, with an effective frequency range of 20Hz to 20kHz. They use detachable 0.78mm 2-pin connectors paired with a high-purity silver-plated OFC copper cable terminated with a 3.5mm stereo jack (STD version). Included accessories comprise two sets of acoustic nozzles, three pairs of silicone ear tips (S/M/L), four acoustic tuning foams, six silicone rings, a carrying case, and a user manual.
