Audio/IEMs
“The 7Hz Salnotes Zero delivers exceptional sound quality for budget IEMs with its 10mm dynamic driver featuring a metal composite diaphragm, achieving very good timbre and low distortion scores. While significant treble spikes and comfort issues during prolonged use are notable tradeoffs, the 0.78mm 2Pin detachable cable and solid frequency response of 10-20000Hz make this a strong entry point for IEM enthusiasts seeking audiophile-grade performance under $30.”
