7Hz x Crinacle Zero: 2

Name: 7Hz x Crinacle Zero: 2
Brand: 7Hz

Budget$25

Co-tuned with Crinacle for strict tonal accuracy: tight sub-bass, clean mids, and low distortion for budget IEM testing.

Key specs

Reference$300–350

The long-standing open-back reference for listening tests: even mids, low distortion, and comfort that survives long ABX sessions.

Best value$90–120

A studio staple since 1991: closed-back isolation and a detailed top end that makes channel and noise checks obvious.

Budget$30–45

A budget stand-in for far pricier open-back references — good enough to hear channel balance and distortion differences in blind tests.
