Stagg SPM-435 – 4-Driver Sound-Isolating In-Ear Monitors (Black / Transparent)

The Stagg SPM-435 are 4-driver, sound-isolating in-ear monitors designed for live use, rehearsal and detailed everyday listening.

Each earpiece uses two dynamic drivers for low and low-mid frequencies and two balanced armature drivers for mids and highs. Working across separate frequency ranges, they aim to keep the sound clear and controlled at stage levels, with a more even balance than single-driver earphones.

With a quoted frequency range up to 10 Hz – 40 kHz (varies slightly between listings), 108 dB/mW sensitivity and 30 Ω impedance, the SPM-435 are easy to drive from wired and wireless IEM packs, interfaces and portable devices, while offering enough level for drummers and loud stages. 

The in-ears are supplied with three pairs of memory foam tips and two pairs of silicone tips, helping you achieve a proper seal for isolation and consistent low end. A compact EVA hard case is included for storage between gigs. They’re available in Black and Transparent finishes, so you can choose a discreet or more visible look. 

In short: a practical, affordable set of 4-driver monitors for players moving from standard earbuds into purpose-designed stage in-ears.
