Electro-Voice HM 2 - Cardioid Condenser Headset Microphone with TA4F Connector

Electro-Voice HM 2 - Cardioid Condenser Headset Microphone with TA4F Connector

The Electro-Voice HM 2 is an electret condenser headworn microphone with a cardioid polar pattern , designed to deliver clear, controlled vocals while keeping your hands free. The lightweight (25g) headband sits behind the head and remains stable even during movement, while the flexible boom allows precise capsule positioning for optimal intelligibility and gain-before-feedback. The capsule features a 30Hz-18kHz response and proximity effect similar to a handheld vocal microphone , facilitating a natural transition between the two types of miking.

Includes a black windscreen and an integrated 1.2 m cable terminated in TA4F , compatible with all Electro-Voice bodypacks . For wired applications, a TA4F→XLR adapter such as the TXA can be used. Its 4 mV/Pa sensitivity , 120 dB max SPL , and 1 to 10 V DC power supply are suitable for professional portable wireless systems used in stages, classrooms, gymnasiums, and places of worship.

Main features

• Transducer : Cardioid electret condenser for greater off-axis rejection and improved gain before feedback.
• Lightweight and stable : headband behind the head, weight only 25g and adjustable flexible boom.
• Natural voice response : 30 Hz–18 kHz with proximity effect similar to a handheld vocal microphone.
• Wireless Ready : 1.2m fixed cable with TA4F , compatible with EV/Telex beltpacks.
• Technical performance : sensitivity 4 mV/Pa (680 Ω load), max. SPL 120 dB , power supply 1–10 V DC, typical current 500 µA at 9 V.
• Anti-glare finish : non-reflective black; windscreen included .

Product benefits

• Comfort and freedom of movement without compromising microphone placement thanks to the rear headband and flexible boom.
• Greater clarity in noisy environments thanks to its cardioid directivity and constant proximity to the mouth.
• Immediate integration with EV systems (TA4F), with the option of wired use via adapter.
• Discreet appearance on camera and stage with matte black finish and low-visibility windscreen.

Use cases

• Presenters, teachers and lecturers who require hands-free operation.
• Vocalists, dancers, fitness instructors, and highly mobile musical theater professionals.
• Places of worship and corporate events where intelligibility is a priority.

Frequently Asked Questions

• Is it a dynamic microphone? No. The HM 2 is an electret condenser microphone and requires biasing (1–10 V DC) from the bodypack or a suitable adapter.
• What wireless systems does it work with? All Electro-Voice beltpacks with TA4F (e.g., R200, RE-2/RE-1, RE3), and many Telex systems that share the same pinout.
• Can I connect it directly to an XLR? Not directly; for wired use, use a TA4F-to-XLR adapter that provides the correct power.
