Letshuoer Cadenza 4 Wired IEM

In general, dynamic drivers in your IEMs tend to provide power and fullness, while balanced armature units can deliver detail and focus. The Letshuoer Cadenza 4 is an IEM that brings both flavors to bear—with rock-solid build quality to boot. The 10-millimeter dual-chambered beryllium-coated dynamic driver is the central character here, providing excellent transient response thanks to its impressive rigidity. The three balanced armature drivers alongside are from both Knowles and Sonion to deliver a level of detail that wouldn’t easily be possible with just the dynamic driver. Letshuoer partnered with Heygear Technology for a top-tier earphone chassis as well, which uses both CNC’d aluminum alloy faceplate and a 3D-printed resin shell. The Cadenza 4 also comes with a 392-strand high-purity silver-plated copper crystal cable with L-shaped terminations that are swappable between 2.5-, 3.5-, and 4.4-millimeter plugs to deliver a steadfast connection with supreme compatibility.
