Its battery-powered operation offers true mobility, making it an excellent choice for performers who prefer a wired, self-contained monitoring system.

Detailed Quad-Driver Monitoring

The SPM-435 Transparent In-Ear Monitors feature a quad-driver system with two dynamic and two balanced armature drivers, delivering a full, balanced frequency response with rich lows, defined mids, and crisp highs. The transparent housing offers a modern, professional look while allowing a glimpse of the precision-engineered internal components.

Their sound-isolating design provides superior ambient noise rejection, ensuring you hear only your mix with maximum clarity. Multiple ear tip options are included for a secure, comfortable fit — ideal for extended use on stage or in the studio.

Flexible, Portable, And Stage-Ready

With its 3.5mm headphone output, the SIA-ST connects directly to the SPM-435 earphones or other professional-grade IEMs. It runs efficiently on a 9V battery (not included), removing the need for mains power and keeping your setup simple and clutter-free.

The SPM-435 Transparent earphones include a detachable 1.2m cable with a 3.5mm mini-jack connector, making them compatible with a wide range of mixers, interfaces, and portable devices. A protective EVA case and a selection of ear tips ensure that everything is ready for travel and performance.
