Our Verdict

7HZ Timeless

TRUTHEAR x Crinacle ZERO

The 7HZ Timeless and the TRUTHEAR x Crinacle ZERO are both IEMs designed for audiophiles. Depending on your preferences, you might opt for one over the other. The 7HZ feature a single planar driver that delivers extremely accurate bass and mids with a veiled treble response. By contrast, the TRUTHEAR feature a dual-driver design with an over-emphasized bass and prominent treble. The TRUTHEAR are the slightly more comfortable of the two, though, so they're a better choice for longer listening sessions.
