Introduction

TWISTURA makes its debut in the audio market with the D-Major, a single-driver Hi-Fi IEM. Key features such as a detachable tuning nozzle system and a comprehensive accessory package position it as a fresh and compelling contender in the entry-level segment.

Design & Build Quality

The D-Major features a solid zinc-alloy shell with an electroplated glossy finish, showcasing a rounded-square design reminiscent of a polished fingernail. The faceplate incorporates an opaque circular resin insert, while three vent holes on the side of the shell manage air pressure from the dynamic driver. Despite its distinctive shape and substantial build, these wired earphones offer excellent wear comfort during extended listening sessions and provide effective passive noise isolation when paired with suitable ear tips.

The included cable—though somewhat slender—employs Litz-structured OFC silver-plated copper wiring with thermoplastic insulation, terminating in a gold-plated 3.5mm straight plug. It remains flexible, durable, and resistant to tangling.

Technical Specifications

At its core, the D-Major houses a 10mm dual-chambered, dual-magnet dynamic driver with a beryllium-coated polyurethane composite diaphragm. This configuration strikes a careful balance between rigidity and flexibility, enabling optimal performance across the entire frequency spectrum.

Accessories & Package Contents

TWISTURA D-Major comes with a comprehensive set of accessories, including:

• TWISTURA D-Major IEMs
• Stock cable
• PU leather storage pouch
  
• Six pairs of ear tips (S/M/L) 
• Blue-ringed tuning nozzles
• Red-ringed tuning nozzles
• TWISTURA Type-C DSP headphone amp dongle
• Documentation (user manual and QC card)

DSP Dongle Performance

The bundled DSP dongle, which features a 3.5mm single-ended jack, likely utilizes the Conexant CX31193 chipset. It delivers a balanced-neutral tuning that complements the D-Major's sonic character. While the wired earphones perform adequately from standard smartphone outputs, pairing them with the included dongle—or a higher-quality source—enhances dynamics, clarity, and tonal richness.

Sound Performance

The detachable nozzle system offers three distinct sound signatures:

• Red Ring Nozzles:
  U-shaped tuning with an enhanced low-end emphasis and slightly recessed upper mids/treble, providing a smooth and balanced presentation.
  
• Black Ring Nozzles:
  Mild U-shaped profile with elevated upper mids and treble sparkle, maintaining a moderate bass presence.
  
• Blue Ring Nozzles:
  A brighter U-shaped signature with noticeable emphasis on upper mids and treble, resulting in a neutral-bright tonal balance.

Technical Performance

The D-Major demonstrates an impressive soundstage, presenting notable width, height, and depth. Its stereo imaging constructs a layered, concave soundscape with precise instrument placement. The driver exhibits excellent coherency and transient speed, preserving clarity even in complex musical passages. Micro-dynamic resolution is particularly commendable for this price point, retrieving fine details and subtle nuances with confidence—setting these in-ear earbuds apart from many competitors.

Conclusion

The TWISTURA D-Major represents an outstanding value proposition, combining a versatile tuning system, solid construction, and a comprehensive accessory package—including the considered inclusion of a DSP dongle. It successfully caters to budget-conscious audiophiles seeking a flexible, well-built gateway to high-quality portable audio. This Hi-Fi IEM firmly establishes TWISTURA as a brand to watch in the competitive entry-level market.
