KZ Castor Pro
Featuring a dual 10mm dynamic driver array with independent low and mid-high units and four tuning switches for 16 sound profiles, the KZ Castor Pro offers extensive sound customization. Its dedicated bass driver provides punchy, well-defined lows that don't bleed into the mids, while the ergonomic design and detachable cable add durability. At a budget-friendly price, this IEM suits bass lovers and tuning hobbyists, but a call quality score of just 16/100 makes it unsuitable for phone conversations.
