The Zero utilize a 10mm dynamic driver with a metal composite diaphragm. I did not find driver flex on my pair, but this may depend on the ear tips used and your ear anatomy. The Zero’s squarish shells have some prominent angled edges. The shells are relatively light, though I experience slight discomfort with prolonged usage. Isolation on the Zero is above average and quite decent, considering they are vented. The housings are quite well-built, nothing to complain considering the price! One can choose from a black, white, or blue shell during ordering.įor 20 bucks, the shells are quite well-built, though the silver faceplate may be a fingerprint or scratch magnet if one is not careful.

The Zero feature a plastic chassis with an overlying stainless-steel faceplate. To not add aftermarket confounders, which may affect the sound, I completed the following review with the stock ear tips and cable. The former give more bass with a compressed soundstage, while the latter provide less bass but give a slightly bigger soundstage. Three pairs of ear tips come with a taller and narrower bore, whereas the other three come with a shorter and wider bore. Well, considering the Zero cost less than many restaurant meals, we can’t complain too much about the spread of accessories provided. Packaging The packaging is pretty generic looking, but of course, a package does not maketh an IEM! In the box Cable: 4-core high-purity oxygen-free copper cable.Frequency Response (Hz): 10 Hz – 20 kHz.Drivers : 1 x 10 mm dynamic driver, metal composite diaphragm.7Hz also recently entered the dongle DAC/amp game with the 71 Mobile DAC. Some of their other notable IEMs include the Eternal, i77, i88, and the i99. 7Hz then followed up with the acclaimed Dioko, which are a collaboration with famed reviewer Crinacle. In fact, we have to thank 7Hz for starting the ball rolling for the current craze for IEM planars with the introduction of the Timeless. This ideal is always at the forefront for their tuning the aim of their products is to project one into audio nirvana, as per the company slogan.

The 7Hz name is eponymous to the Theta Wave, a frequency that is linked to meditation and harmony. 7Hz (and their sub-brand Salnotes) was formed in 2018.
