TRUTHEAR ZERO BLUE2
A dual-driver setup with a 10mm driver (N52 magnet) and 7.8mm driver (N55 magnet) in a DLP-3D printed cavity with silicone capping delivers a 9Hz–41kHz response using construction typical of pricier custom earphones. The 294-core copper silver-plated cable and optional mic cable provide tangle-free durability and clear communication for calls and gaming. This makes the ZERO:BLUE2 ideal for budget-conscious listeners and gamers who need a single in-ear for music, monitoring, and voice chat.
