The TRUTHEAR x Crinacle ZERO:BLUE2 is a dual-dynamic-driver IEM that pairs a 10mm bass driver with a 7.8mm mid/treble driver, rated at 5.8Ω and 119.5dB/Vrms, with a detachable 0.78mm 2-pin cable and an optional mic cable. It suits listeners who want one pair for music, calls and gaming, with kits that add the KEYX USB-C DAC.
Who the TRUTHEAR ZERO:BLUE2 is for
Everyday music: TRUTHEAR says the upgraded 10mm bass driver gives deeper, punchier bass than the original ZERO, while the 7.8mm driver handles the mids and highs.
Calls and gaming: The With Mic version adds an OFC cable with an in-line mic alongside the standard coaxial cable, so one pair covers music, calls and game chat.
Fit and tuning tinkerers: Three pairs of ear tips, four pairs of foam tips and a 5Ω impedance adapter come in the box.
Phones without a jack: The With KEYX DAC kits add TRUTHEAR's CS43131 USB-C to 3.5mm dongle for phones, tablets and laptops.
Skip it if: you want a 4.4mm balanced cable; every ZERO:BLUE2 version ships with 3.5mm cables only.
Versions: Standard includes a 2-strand silver-plated copper coaxial cable; With Mic adds a 2-strand OFC cable with in-line mic
Kit options: IEMs Only, or With KEYX DAC (adds the TRUTHEAR KEYX CS43131 USB-C to 3.5mm DAC/amp)
In the box: ZERO:BLUE2 IEMs, cable(s) per version, 3 pairs ear tips (S/M/L), 4 pairs foam tips (3 M, 1 S), 5Ω impedance adapter, manual, anime card
