Description

This is a genuine open box opportunity on one of the most well-regarded affordable headset microphones in the worship and live production world. GearTechs has sold over 2,500 units of the THOR Hammer SE-9 and SE-11 over the past several years, and these open box units come from demo or return stock. Each microphone has been used for demonstration purposes, is fully functional, and includes the manufacturer's warranty. Stock is limited, so if you have been considering the SE-9, this is a smart time to grab one at a savings.

The THOR Hammer SE-9 is a headset microphone built around a Danish omnidirectional condenser capsule. That might sound like marketing language, but it matters in practice. Danish capsule design has a long reputation in professional audio for producing clear, natural voice reproduction without the hyped or pinched sound you sometimes hear from lower-cost alternatives. The SE-9 has been carefully tuned to handle both male and female voices with clarity and warmth, making it a strong performer for speaking, singing, and everything in between.

The SE-9 uses a 90mm boom, which positions the capsule closer to the mouth than the longer SE-11 variant. This makes it a popular choice in stage and theater settings where a shorter, more discreet profile is preferred. The boom is flexible, so it can be adjusted to sit exactly where you need it. 

One of the most practical features of this microphone is its detachable cable. If a cable is damaged, you replace just the cable rather than the entire headset. This is a significant long-term value advantage in high-use environments like churches or schools where gear gets a lot of wear. 

The microphone ships in a protective case and includes the dual-ear adapter. Colors available in open box stock may vary, so contact GearTechs if you have a specific color preference and we will confirm what is currently on hand.

Setup Tips

  • Position the boom correctly: The flexible 90mm boom should gently shaped so the capsule sits at the corner of the mouth, slightly off to the side. Avoid placing it directly in front of the lips, as this can pick up plosives and breath noise. 
  • Use the dual-ear adapter for active speakers: The included wrap-around adapter provides extra stability for singers, actors, or anyone who moves a lot on stage. If you are using the microphone for a speaker who moves moderately, the single-ear hook works well on its own. Snap the adapter on when you need more security.
  • Gain staging matters with omni mics: Because this microphone is omnidirectional, it picks up sound from all directions, not just from directly in front of the capsule. This is generally excellent for natural voice capture, but it does mean that stage monitors and nearby speakers need to be managed carefully to avoid feedback. Work with your sound engineer to set gain appropriately and position monitors to minimize bleed.
  • Take advantage of the detachable cable: If the cable shows wear or damage over time, you do not need to replace the entire headset. Replacement cables for the THOR Hammer are available and are a simple field swap. This is one of the best long-term cost advantages of this system, especially in high-turnover environments like church volunteer teams or school programs.
