Shure MX153 Earset Headworn Microphone — Professional Speech Clarity

The Shure MX153 Earset Headworn Microphone is a subminiature professional earset built for speech clarity in live presentation, worship, broadcast, and conferencing. An ultra-lightweight single-ear frame pairs with an omnidirectional condenser capsule for a discreet mic. The tan finish blends naturally with a wide range of skin tones.

What Sets the MX153 Apart

What separates the MX153 from entry-level earsets is Shure's CommShield RF rejection and a Kevlar-reinforced cable for daily professional use. CommShield guards the capsule against interference from cellular RF devices and digital bodypack transmitters. The capsule also delivers enhanced plosive protection with no proximity effect.

Capsule & Polar Pattern

A subminiature electret condenser capsule sits at the heart of the MX153, tuned for speech reproduction. The omnidirectional polar pattern picks up sound evenly from all directions, so voice level stays consistent as the speaker turns their head.

• Microphone Type: Subminiature electret condenser — purpose-built for clear speech
• Polar Pattern: omnidirectional — voice level stays consistent as the speaker turns their head
• Frequency Response: 20 Hz – 20 kHz

Performance & Signal Specs

Electrical performance is calibrated for Shure wireless bodypack gain structure, preserving vocal nuance without overloading the transmitter. The 107 dB SPL ceiling handles loud talkers, while the 34 dB noise floor keeps silent passages clean.

• Maximum SPL: 107 dB SPL (1 kHz, 1% THD) — headroom for animated speakers
• Sensitivity: -41 dBV/Pa — matched to Shure bodypack preamp gain structure
• Dynamic Range: 73 dB — clean signal from whisper to raised voice
• Equivalent Noise Level: 34 dB SPL (A-weighted)

Connectivity, Cable & Build

Connectivity runs through a locking TA4F (TQG) 4-pin mini-XLR connector for direct plug-in to Shure wireless bodypack transmitters. A 1.2 m Kevlar-reinforced cable routes to the bodypack, and the 19.76 g frame stays stable.

• Connector: TA4F / TQG 4-pin mini-XLR (female) — direct plug-in to Shure bodypacks
• Cable Length: 1.2 m — flexible routing to belt-mounted transmitters
• Weight: 19.76 g — ultra-light for multi-hour wear
• Operating Voltage: 1–5 V

Who Is the MX153 For

The MX153 is the right choice for presenters, worship leaders, broadcasters, fitness instructors, and educators who need a discreet, hands-free microphone for consistent speech clarity in live environments. Worship services benefit from the omnidirectional pickup during sermons, while corporate A/V teams rely on CommShield rejection in RF-dense venues.
