The LETSHUOER DZ4 is a wired IEM with three 6mm titanium-dome dynamic drivers and a 6mm passive radiator per side, a four-way acoustic tube layout and a semi-open 3D-printed resin shell, on a 0.78mm 2-pin cable with a 3.5mm plug. It suits listeners who want an all-dynamic multi-driver IEM for everyday use with a phone dongle or DAP.
Who the LETSHUOER DZ4 is for
Bass lovers: LETSHUOER says the 6mm passive radiator extends the low end further, while the three dynamic drivers handle treble and fast transients.
Multi-driver fans: Four acoustic tubes and a two-way crossover give each of the four units its own role, per LETSHUOER.
Long listening sessions: The semi-open faceplate lets air vent from the shell, which LETSHUOER says keeps long-term wear comfortable.
Cable upgraders: The stock cable detaches at standard 0.78mm 2-pin sockets, so a balanced cable can be added later.
Skip it if: you need a balanced plug out of the box; the stock cable ends in a 3.5mm single-ended plug only.
