Every Style of Music

Through the relentless efforts of audio engineers and audiophiles, Rose Technics has achieved a harmonious balance with premium drivers, completely breaking the convention of assessing sound solely based on price, and bringing an affordable audio experience to the next level. The Star City 5 PRO is all you need for both pop vocals and orchestral instrumental music.

1DD + 2 BA

Star City 5 PRO features a 10mm Japanese LCP composite diaphragm dynamic driver unit with N52 magnetic circuit. The combination reduces partition vibration and lowers distortions, delivering deeper bass and a wider soundstage performance. Coupled with customized Danish balanced armature drivers, Star City 5 PRO brings a wider frequency response range and superior resolution performance.

Tuning and Engineering

Tuned by a former Sony engineer, Star City 5 PRO features a physical-electronic hybrid crossover acoustic system. And with a next generation 3D-SLA printed resin chamber with CNC stainless steel rear cavity, these earphones effectively reduce overall distortion rates, ensuring smoother integration among driver units. The whole package brings a cohesive sound without a sense of disjointedness.

Stable and Comfy

An ergonomic design ensures a stable & comfortable wearing experience. The full-chain pressure circulation system utilizes five customized dampers to optimize pressure levels, reducing ear pressure and achieving superior bass texture while minimizing possible distortion. This makes Star City 5 PRO a lifesaver for those sensitive to ear pressure or looking to minimize listening fatigue during longer sessions.

Audiophile Grade Cable

Star City 5 PRO comes equipped with dual-strand 6N OCC monocrystalline copper upgrade cable. Featuring additional wire cores and superior shielding layers, these IEMs deliver a purer sound foundation, higher sound density, and enhanced resolution. MMCX connectors provide versatility for the earphones.
