7Hz indicates theta wave frequency reminiscent of meditation and peaceful frequencies. The name reflects the brand’s motto of designing peaceful and musical tuned IEMs that complement different genres together.
After their very successful planer magnetic IEM Timeless, 7Hz launched the Eternal for the tribute to their 10th Anniversary, which innovatively adopts a large size 14.5mm LCD polymer diaphragm for the driver while is complemented with an N52 magnet and unique cavity structure. The craftsmanship of Eternal IEM looks very good with a sapphire optical glass faceplate and CNC aluminium cavity.
7Hz Eternal earphone features a specially designed 14.5mm liquid crystal polymer diaphragm and precise speaker structure design, to achieve ultra-broadband response and dynamic range. It is a high-end in-ear monitor.
Like the previous model, Eternal also features an aluminium CNC cavity, resonating with a sapphire optical glass faceplate. This kind of glass is similar to the material used for high-end watches. The sapphire coating is tempered to withstand longtime wearing and accidental fall off. It is durable and wear-resistant. The Eternal has a lightweight design of only 6g per piece.
