The 7Hz G1 is a wired gaming IEM from 7Hz's G series with a 10mm dual-magnetic, dual-cavity dynamic driver and DLC diaphragm, rated 18Ω and 107dB/V, on a detachable 0.78mm 2-pin cable. It suits gamers and everyday listeners who want a budget set in black 3.5mm or white USB-C form, with an optional mic.
Who the 7Hz G1 is for
Game chat and calls: The mic versions add a silicone microphone on the cable, which 7Hz pitches for gaming and everyday calls.
USB-C devices: The white version ends in a USB-C plug with the mic on the cable, for devices with a USB-C port instead of a headphone jack.
Long gaming sessions: 7Hz designed the G1 shell for extended wear and says it is comfortable enough to wear while sleeping.
Harman-style tuning: 7Hz says the G1's frequency response closely follows the Harman target curve, with THD under 0.5% at 1kHz.
Skip it if: you want a 4.4mm balanced cable or a black USB-C version; the G1 comes as black 3.5mm (with or without mic) or white USB-C with mic.
