Professional Audio Engineering Team Design

We are a professional audio engineering team dedicated to developing premium earphones and accessories for musicians and audiophiles. After launching our anti-earwax Flex silicone ear tips, we created Flow as our second specialized ear tip series, focusing on solving the universal pain point of suppressed treble caused by narrow-bore stock tips. Every design is refined via repeated acoustic testing to remain the true sound signature of your HiFi wired IEMs.

Wide Trumpet Bore Acoustic Design

Flow is built with a standard 4.5mm inner trumpet-shaped channel to minimize airflow resistance and reduce treble attenuation. This wide-bore design eliminates muffled highs from narrow stock tips, delivering an open soundstage and unaltered delicate treble details for vocals, classical and acoustic music. The 4.5mm inner bore fits all standard IEM nozzles for a snug acoustic seal that blocks outside ambient noise effectively.

Premium Skin-Friendly Silicone Material

Flow features hypoallergenic soft elastic silicone that conforms to your ear canal without that “plugged” pressure. The smooth surface is stain-resistant, washable and holds its shape after repeated swaps. This skin-friendly material ensures long-wearing comfort for extended listening sessions, whether you are monitoring tracks in the studio, commuting on your daily train ride, or enjoying a quiet evening at home.

Precise Multi-Size and Universal Nozzle Fit

Flow is available in three fixed outer diameters: S 11mm, M 12mm and L 13mm. The universal 4.5mm inner bore fits all standard IEM nozzles, ensuring broad compatibility across different earphone models. The precise sizing and snug acoustic seal effectively blocks outside ambient noise, allowing you to focus on your music without distraction or the need for constant readjustment during use.

Natural Sound with No Coloration

From commute to studio, Flow stays consistent. Whether you're monitoring tracks in the studio, zoning out on your daily train ride, or enjoying a quiet evening at home, these ear tips deliver reliable performance. The best part: without sonic coloration. Your IEMs sound exactly how their tuners intended — Flow simply lets that sound reach your ears clearly, preserving the original tuning and character of your earphones.
