HE Bu Lianshi 1DD + 4BA Hybrid IEMs with 3.5mm & 4.4mm Plugs

HE Bu Lianshi 1DD + 4BA Hybrid In-Ear Monitors

The HE Bu Lianshi combines a dynamic driver with four balanced armatures in a hybrid earphone design inspired by Bu Lianshi of the Three Kingdoms era. Aluminum-alloy faceplates, lightweight resin shells and a detachable silver-plated OFC cable bring together a distinctive appearance and a versatile wired listening setup.

Key Features

• Hybrid driver configuration: one dynamic driver and four balanced armatures.
• Aluminum-alloy faceplates paired with resin acoustic cavities.
• Customized crossover network for integration across the frequency range.
• Tuning aimed at balanced bass, natural vocals and smooth treble.
• Detachable four-core braided silver-plated oxygen-free copper cable.
• Interchangeable 3.5mm single-ended and 4.4mm balanced source plugs.
• Approximately 1.2m cable with a transparent PVC jacket.

Inspired by Three Kingdoms Heritage

Bu Lianshi's design draws on the elegance of its historical namesake, pairing understated metal faceplates with resin shells. The combination is intended to balance a refined finish with comfortable everyday wear, whether listening from a portable player on the move or a DAC/amp at home.

Five-Driver Hybrid Acoustic Design

A dynamic driver provides the bass foundation, while four balanced armatures handle midrange and high-frequency reproduction. A customized crossover coordinates the driver groups, with the tuning focused on a coherent presentation across vocals, instruments and lower-frequency accompaniment.

Balanced Tuning for Everyday Listening

The supplied tuning description emphasizes moderate bass with natural decay, a smooth midrange and gently extended treble. Rather than focusing on one frequency band, the Bu Lianshi aims for an even-handed presentation suited to vocals, pop, classical and instrumental music. Perceived balance and comfort vary with ear-tip selection, fit, source and recording.

Aluminum Faceplates and Resin Shells

The aluminum-alloy faceplates provide a robust exterior, while the resin cavities keep the design lightweight. The materials and internal acoustic structure are designed to manage unwanted resonance without sacrificing wearing comfort.

Detachable Cable with Two Source-Plug Options

The included cable supports interchangeable 3.5mm single-ended and 4.4mm balanced plugs, allowing connection to appropriately equipped players and DAC/amps. Select the plug that matches your device's headphone output. A 4.4mm balanced connection requires a compatible balanced source and does not guarantee lower noise on every device.

The detachable earphone connection also allows future cable replacement. The exact earphone-side connector standard is not stated in the supplied specifications; confirm compatibility before purchasing a third-party replacement cable.

Four-Core Silver-Plated OFC Cable

The four-core braided cable uses silver-plated oxygen-free copper conductors inside a transparent PVC jacket. Its flexible construction is designed for comfortable routing and everyday handling. The supplied jacket specification lists an outer diameter of 1.45mm. Cable length is 1.2m ±5%.

Compatibility and Care

Connect the 3.5mm plug to a suitable single-ended headphone output, or use the 4.4mm plug with a compatible balanced output. Phones without a headphone socket require a suitable DAC/adapter. Lower the volume before connecting, and handle detachable connectors by their housings rather than pulling the cable.
