BASN Bmaster5 In-Ear Monitors – 1DLC Diaphragm + 4BA, 5-Driver IEMs (Midnight Black)

Premium hybrid IEM design for stage and studio

BASN Bmaster5 combines a 10mm diamond-like carbon (DLC) diaphragm with four balanced-armature drivers, delivering a fast transient bass and detailed highs without harsh sibilance. This hybrid setup is crafted to balance warmth with clarity, offering nuance in vocals and instruments while staying responsive to dynamic performances.

To ensure reliable, durable performance, the Bmaster5 uses Pentaconn connectors that reduce contact resistance and provide a sturdier connection. The elastic connector structure helps extend lifespan and enables smooth plug-in and removal, supporting demanding nights on tour or in the rehearsal room.

Immersive sound with strong isolation

The shell is designed to block external noise so you can focus on the blend of your instruments and voice. It remains compatible with a wide range of digital sources via the standard 3.5 mm stereo plug, making it easy to pair with headphone amps, laptops, or audio interfaces for both live performances and studio work.

• Hybrid driver system combines accurate bass with clear mids and trebles
• Sturdy Pentaconn connection supports stable, repeatable plug-ins
• Effective sound isolation for focused listening in loud environments

Durability, versatility, and easy handling

Two upgrade cables come with the set: a 4-core OFC cable tailored for pure music listening and monitoring, and a mic-cable variant with an inline volume control for daily use with phones. These cables are designed to withstand the rigors of stage life while remaining flexible for on-the-go setups.

• Detachable, durable cables for stage and studio use
• Inline mic cable for convenient control on mobile devices

Comfortable, secure fit for long sessions

Two tip styles—silicone and memory foam—are provided in 12 sizes to help you achieve a comfortable seal. Adjustable ear hooks and multiple tip options let you tailor the fit so the monitors feel like a custom pair for your ears, even during lengthy gigs.

Protective case and thoughtful extras

The aluminum case keeps the Bmaster5 and accessories secure between sessions, and a leather pouch adds portable storage for a quick carry-on setup. A cleaning brush, a 1/4 adapter, and replacement tips are included to support regular care and quick maintenance.
