AKG C 555 L Headset Condenser Microphone

AKG C555 L — Head-Worn Condenser Microphone for Stage and Presentation

This professional head-worn condenser microphone is built for hands-free operation in live performance, corporate presentation, and fitness instruction. The headset rests on a behind-the-neck headband and positions a cardioid capsule at the corner of the mouth for consistent, close-miked vocal capture. A pre-polarized condenser transducer delivers a frequency response of 80 Hz to 20 kHz covering the full range of the speaking and singing voice, while the cardioid polar pattern rejects ambient stage noise.

What Sets this Model Apart

A moisture shield sits in front of the capsule to keep sweat and humidity away from the diaphragm during energetic performances, while a flexible shock mount isolates the transducer from body and cable noise so movement on stage does not translate into thumps in the PA. The boom arm mounts on either the left or right side of the headband, letting the wearer position the capsule on their preferred side.

Cardioid Capsule — Vocal Clarity With Stage Noise Rejection

By rejecting sound from the rear and sides, the cardioid pattern minimizes bleed from stage monitors, instruments, and audience noise, allowing the front-of-house engineer to run the vocal channel at lower gain with less feedback risk.

• Polar Pattern: Cardioid — focused front pickup that rejects ambient and monitor noise
• Frequency Range: 80 Hz - 20 kHz — full coverage of speech and singing fundamentals
• Equivalent noise level is 30 dBA, providing quiet self-noise for clean vocal capture.

Mini XLR Output — Compatible With Wireless and Phantom Power

This headset terminates in a 3-pin mini XLR female connector with a 1.5 m cable, making it a drop-in fit for AKG WMS Series body-pack transmitters, the B29 L battery power supply, and the MPA VL adapter for external phantom powering. The same microphone moves between wired and wireless rigs.

• Connector: Mini XLR, 3-pin female — standard for AKG bodypack transmitters
• Cable Length: 1.5 m — enough slack to route to a belt-pack
• Operating Voltage: 9 V (2 V - 10 V) — runs from bodypack battery or phantom adapter
• Sensitivity: 25 mV/Pa — hot output level that keeps preamp gain low

Lightweight Headband — Built for Long Sets and Active Performers

At only 26 g on the head, this headset is light enough to wear through multi-hour conferences, theater runs, and fitness classes without fatigue. The flexible boom arm holds its position once set so the capsule stays at a consistent distance from the mouth.

• Net Weight: 26 g — light enough for all-day wear without pressure points
• Max SPL: 120 dB (1% THD) — handles loud vocalists without distortion
• Finish: Matte black — visually discreet on camera and under stage lighting

Who Should Choose the AKG C555 L

This model is the right choice for presenters, fitness instructors, theater performers, and worship leaders who need a hands-free microphone that stays out of the way while delivering clear, consistent vocal reproduction. Lead vocalists in choreographed movement also benefit from the secure headband and the cardioid pattern's resistance to stage monitor bleed. The included W444 windscreen reduces plosives, and the moisture shield makes the headset reliable for high-energy aerobics, dance, and outdoor events.
