Description

The THOR Hammer SE-11 is a professional headset microphone built around a Danish omnidirectional condenser capsule - the same type of capsule technology used in high-end broadcast and performance microphones. It has been carefully tuned to reproduce both male and female voices with clarity and warmth, making it a practical choice for speaking and singing applications alike. At just 8 grams without the cable connector, it is light enough that most wearers forget they have it on.

This listing is for an open box unit that has been used for demonstration purposes and is fully functional. GearTechs has sold nearly 2,500 of the SE-9 and SE-11 over the past few years, and these open box units come from returns and demo stock - not damaged or repaired units. The manufacturer's warranty remains intact. If you have been considering the SE-11 and want to save money on a mic that performs like new, this is a straightforward opportunity to do that.

The SE-11 version features a longer 115mm (approximately 4.5 inch) boom compared to the shorter SE-9, which makes it easier to position the capsule closer to the mouth without the mic feeling cramped against the face. This is especially useful for speakers who move a lot on stage. The boom is flexible and can be shaped to fit a variety of face shapes and ear positions. The single-ear design keeps the microphone low-profile and comfortable for extended wear, and a dual-ear wrap-around adapter is included for added stability during high-movement performances.

The cable is detachable and easy to replace, which is a meaningful practical advantage in production environments where cables take abuse over time.

Compatibility Guidance

THOR offers the Hammer SE-11 in multiple connector options including 3.5mm (for Sennheiser), XLR3 (for AKG and Audix), Hirose 4-pin (for Audio-Technica), and MIPRO. If you need one of those versions, contact GearTechs to check availability. The open box stock is limited and may not include all connector types.

The cable on the SE-11 is detachable and replaceable, so in theory a different connector cable could be used.

Setup Tips

  • Shape the boom before wearing: The flexible boom on the SE-11 can be gently bent and repositioned to suit different face shapes. Position the capsule near the corner of the mouth for the best balance of clarity . Avoid placing it directly in front of the mouth where plosive sounds (p and b consonants) can cause issues.
  • Use the dual-ear adapter for high-movement applications: The included wrap-around dual-ear adapter adds significant stability for singers, performers, or anyone who moves actively during their presentation. It takes about 30 seconds to attach and can prevent the mic from shifting during a service or performance.
  • Handle the detachable cable with care: The cable connection point is where most headset mics fail over time. When disconnecting the cable from the mic body, pull from the connector - not from the cable itself. Store the mic in its case when not in use to avoid stress on the connection point.
  • Open box does not mean compromised: These units were used for demonstration, not returned due to defects. They have been checked for functionality and carry the manufacturer's warranty. Inspect the unit when it arrives and contact GearTechs promptly if anything looks off - we stand behind what we sell.
