Price: 5,500 BDT

Warranty: 1 Year Replacement Warranty

Product Overview

If the standard STA-Pro is the introduction to Hi-Fi, the EarAcoustic STA-Pro Ultra is the masterclass. Engineered for audiophiles who crave higher resolution and faster transient response, the “Ultra” edition completely overhauls the internal driver materials.

By swapping standard diaphragms for Graphene and Titanium, this IEM delivers a sharper, more textured, and incredibly immersive soundstage. At HiFi Heaven, we are offering this premium configuration for 5,500 Taka—the ultimate choice for critical listeners under 6k.

Why the “Ultra” is Worth the Upgrade

• Advanced Graphene Bass (10mm): The main driver uses a Graphene Diaphragm, a material harder than diamond yet incredibly light.² This results in bass that isn’t just “loud,” but fast, textured, and distortion-free, even at high volumes.

• Titanium-Plated Highs (6mm): The secondary driver features a Titanium-plated diaphragm.³ This adds a layer of sparkle and air to the treble, bringing out micro-details in cymbals and female vocals that standard drivers miss.

• Easier to Drive: With an impedance of just 18Ω (vs 22Ω on the standard), the Ultra is more sensitive (113dB).⁴ It gets louder and sounds fuller directly from your smartphone without needing a heavy amplifier.

• “Year of the Snake” Aesthetics: The faceplate features a unique, intricate design motif (often styled as the “Silver Angel” or Snake series), set in a glossy resin shell that looks like custom jewelry.⁵

Sound Signature (Ultra Edition)

• Bass: Fast, punchy, and deeply layered.⁶ The Graphene driver removes “mud,” keeping the sub-bass distinct from the mid-bass.

• Mids: Transparent and forward. Male and female vocals have excellent weight and emotional resonance.

• Treble: Extended and airy. The Titanium plating ensures highs are crisp and detailed without being harsh or sibilant.⁷

• Resolution: High-definition.⁸ Perfect for complex tracks where instrument separation is key.
