The G1 from 7Hz are low-cost in-ear headphones featuring a Ø10mm driver with a DLC (Diamond-like carbon) membrane. Its dual magnetic circuit, coupled with its dual acoustic cavity, enables the brand to offer a sound experience that is as close as possible to Harman's curve, offering a transparent sound experience with a natural timbre.
The 7Hz G1 earphones feature a dynamic driver with a DLC (Diamond-like carbon) membrane. The rigidity of this type of carbon gives excellent transient response and high-frequency extension. Furthermore, this driver is equipped with a double acoustic cavity for improved filtering of standing waves and finer control of frequency response. Finally, the driver is equipped with a dual N52 magnetic circuit, improving the sensitivity of the earphones.


The G1 comes with a 3.5mm jack to 0.78mm 2-pin OFC copper cable, ensuring optimum signal transmission so you can enjoy the full performance of the earphones. Furthermore, the cable includes a microphone, so you can make phone calls without taking your earphones out of your ears.
