Photographed: KZ ASX 10 BA Drivers “Big Is Beautiful”
The Knowledge Zenith KZ ASX is a 10 BA earphone in the $100 segment and KZ’s biggest gun so far in the ongoing budget driver war…literally…these earpieces are big oshis, although quite light. It has a frequency range of 10 to 40,000 Hz. At an impedance of 20 Ω and a sensitivity of 106 dB/mW, the KZ ASX is driven easily with any phone. Here some technical photography showing the earphone’s physical features – including a size comparison with the Sennheiser IE 400 PRO. My full review is embedded below – tested at $99-102. Review unit of the KZ ASX supplied by Wooeasy Earphones Store – thank you very much.
