Budding Brilliance

“Natural sound” can be hard to define, but as any audiophile will tell you: you know it when you hear it. Tigerism has sought to capture it in their Helianthus IEMs. Boasting 14.mm planar magnetic drivers, these in-ear monitors deliver a true-to-life listening experience that seeks to reproduce details and nuances as realistically as possible. 

Harnessing planar power

At the core of these IEMs, you'll find a remarkable 14.2mm planar diaphragm, the secret behind their extraordinary sound. Imagine tiny, super-strong magnets and an ultra-thin, finely-tuned layer working together to bring every note to life. It's like having a high-precision musical instrument right in your ears, capturing every detail of your favorite tracks with stunning clarity. 

Acoustic alchemy

Breaking away from conventional dynamic driver designs, these IEMs boast a 15-layer material construction. This sophisticated design fine-tunes every frequency for a mesmerizing listening session. The high frequencies are crisp and precise, the mids resonate with richness, and the lows deliver a depth that's both powerful and articulate.
