The Chinese company Sivga has been making headphones since 2016, and the SV023 model is another indicator of the company’s level. The headphones feature custom 50mm LCP (Liquid Crystal Polymer) composite polymer drivers with a beryllium-coated center body. The handcrafted walnut cups feature perforated memory foam ear cups for breathability.
The whole structure, including the headband made of genuine leather and stainless steel, weighs 318 g. The Sivga SV023 parameters command respect: the reproducible frequency range extends from 20 Hz to 40 kHz, this is with a sensitivity of 105 dB and a nominal impedance of 300 Ohms.
The novelty is completed with a two-meter balanced cable made of copper 6N OCC with a 4.4 mm connector. The kit also includes adapters from a balanced 4.4 mm jack to an unbalanced 3.5 mm jack, as well as from 3.5 mm to 6.35 mm. This comes with a genuine leather bag and a hemp fiber pouch.
For US buyers Sivga SV023 headphones cost $500.
