Intime Shu Mai Limited Edition In‑Ear Monitor Earphones (Hong Kong Exclusive)

The Intime Shu Mai is a Hong Kong–exclusive limited edition in‑ear earphone inspired by one of the city’s most iconic local snacks. Combining a brass sound tube, 10 mm titanium‑coated dynamic driver, proprietary VST2 ceramic tweeter, and 3rd‑generation HDSS acoustic technology, Shu Mai delivers a warm, full‑bodied, emotionally engaging sound that brings vocals and atmosphere vividly to life. Limited to just 168 pairs worldwide, it is a collectible choice for audiophiles and Hong Kong fans alike.

Warm, Full‑Bodied Tuning Inspired by “Shu Mai”

Shu Mai is tuned to sound as rich and satisfying as its namesake: thick, warm, and substantial, yet still detailed and controlled. The brass nozzle, shared with Intime’s MIYABI, gives the overall sound a smooth, slightly warm tonal balance, with especially rich mid‑bass ambience and natural instrumental overtones. Vocals carry strong emotional expression, while the mid‑low frequencies wrap you in a live‑like, immersive presentation that feels like being at the performance.

Advanced Driver System

• 10 mm titanium‑coated bass driver: Titanium’s high rigidity provides fast response and excellent control. Even in a lush, immersive low‑frequency environment, the driver maintains high resolution and detail, offering tight, impactful bass with good texture and speed.
• 3rd‑generation VST2 piezoelectric ceramic tweeter: Multi‑layer ceramic elements greatly increase sensitivity over traditional single‑layer ceramic tweeters, making the unit easier to drive while expanding ultra‑high‑frequency performance above 15 kHz. This improves extension, air, and micro‑detail, while fine‑tuned resonance control ensures smooth, natural treble without harshness.

3rd‑Generation HDSS® Technology – High Definition, Natural Sound

Shu Mai adopts 3rd‑generation HDSS® (High Definition Sound Standard) technology, originally developed by TBI Audio Systems in the USA. At its core is the ETL (Embedded Transmission Line) acoustic module mounted behind the driver, which stabilizes internal air pressure and reduces acoustic interference inside the housing. This allows the earphone to reproduce clean, low‑distortion sound that remains faithful to the original recording, with a wider, more relaxed soundstage and improved phase accuracy.

By controlling internal pressure generated by the bass driver, the 3rd‑generation HDSS module enhances layering, separation, and clarity. The same HDSS module is used in Intime’s flagship “Show,” giving Shu Mai exceptional performance and value within the lineup.

Premium Brass & Resin Housing + NOBUNAGA Cable

The housing combines brass and high‑quality resin for both acoustic performance and aesthetics. Brass contributes to a warm, smooth timbre and richer harmonic decay, while resin helps with weight balance and comfort. The Hong Kong limited edition also comes with a specially selected NOBUNAGA Ibuki 4‑core tinned OFC cable, terminating in a 3.5 mm single‑ended plug.

• Improved separation and instrument placement
• Enhanced soundstage width and layering
• Better signal integrity and musical richness
