ddHiFi ST35 Medical-Grade Silicone Eartips

ddHiFi ST35 (D-Tips) — Medical-Grade Silicone for Unbiased Acoustic Purity

The ddHiFi ST35 (also known as D-Tips) is an audiophile-grade replacement eartip engineered to deliver long-lasting wearing comfort and an uncolored acoustic seal. Unlike conventional aftermarket tips that can bloat low frequencies or artificially sharpen treble, the ST35 focuses on pure transparency—preserving the authentic tuning of your in-ear monitors while maximizing skin tolerance.

• Hypoallergenic Medical-Grade Silicone: Molded from premium, eco-friendly medical-grade silicone, the ST35 features a skin-friendly surface finish that resists ear canal fatigue, itching, and irritation during multi-hour listening sessions.

• Dual-Color Secondary Molding: Engineered with a specialized dual-color structure, blending a natural grass-green outer umbrella with an orange inner core. The firmer inner stem securely grips IEM sound nozzles without slipping, while the soft outer umbrella flexes naturally to the contours of your ear canal.

• Unbiased, Transparent Sound Signature: The internal sound bore is calibrated to maintain an honest frequency response. By optimizing acoustic reflection without altering the manufacturer’s original tuning, it delivers clean air, defined instrument separation, and coherent layering across all genres.

• Universal IEM Nozzle Compatibility: Featuring a 3.5mm inner nozzle diameter, the ST35 fits standard IEM sound stems ranging between 3.8mm and 5.5mm, making it an ideal upgrade for dynamic driver, balanced armature, and hybrid earphones.
