It’s important to note that while not every accessory on this list may be necessary for every job, having a diverse arsenal of wiring tools can help you be better prepared for any situation. As the saying goes, “if you don’t have it, you’re gonna wish you did.” So let’s dive into the world of essential wiring tools and equip ourselves for success in the audio industry.


Straps play a crucial role in securing both microphones and transmitters onto the talent during film, television, or live event productions. They are designed to provide a comfortable and discreet method of attaching these essential audio devices to the body, allowing for optimal sound recording without compromising the talent’s performance or movement. By ensuring that the microphone or transmitter remains in the correct position throughout the scene, straps help maintain consistent audio quality and reduce the need for retakes due to audio issues.

When selecting straps for use in a production, it is important to consider factors such as comfort, durability, and adjustability. A well-designed strap should be made from soft, breathable materials that prevent irritation or discomfort during long periods of wear. Additionally, the strap should provide a secure grip on the body, reducing the risk of slippage or movement during action-packed scenes. Straps should also be easy to adjust and accommodate various body shapes and sizes, ensuring a customized fit for each talent. By prioritizing these features, production teams can effectively secure microphones and transmitters to their talent, enabling them to focus on their performance while delivering high-quality audio recordings.

URSA Chest Straps

URSA Chest Straps are an essential accessory for anyone in the entertainment industry who needs to rig microphones onto sweaty or hairy chests. These straps are designed to reduce noise from hairy chests and allow you to rig on hot, sweaty bodies. The unique gripper strips on the strap keep it from slipping, ensuring that your microphone stays securely in place.

The mic pouch that comes with the URSA Chest Strap is designed to fit all microphone sizes and mounts. The ultra-thin fabric of the pouch is invisible even under tight T-shirts, making it a discreet and versatile accessory. The unique “Cable Keeper” feature of the URSA Chest Strap stops the mic from pulling out of the pouch, ensuring that your recordings are of the highest quality. The one-size-fits-all strap is adjustable and can be used on a variety of body types, making it a versatile and essential accessory for any sound engineer or filmmaker. Whether you are recording dialogue for a film or a live performance, URSA Chest Straps are a reliable and effective solution for rigging microphones onto the chest.


The URSA Back Strap is a new solution for securely rigging microphone or IEM packs to the center of the back, between the shoulder blades. The adjustable gripper straps allow for a comfortable and secure fit, while the transmitter can be rigged with the aerial facing up or down. The back strap comes in medium and large sizes, fitting chest sizes 36-40 inches and 41-45 inches, respectively. It is available in both black and beige, and fits all transmitter/receiver sizes.

URSA Head Straps

The URSA Head Strap is a versatile accessory designed for motion capture artists and puppeteers. This strap allows you to rig one or more microphones, headphones, and markers to the center of the forehead, making it the perfect tool for capturing live vocals during motion capture performances.

Whether you are working on a film set or a live performance, the URSA Head Strap is a reliable and effective solution for rigging microphones, headphones, and markers to the forehead.


Transmitter straps, which are larger than those used for lavaliers, feature a built-in pouch that securely houses the transmitter pack. This design ensures that the pack remains snugly in place without moving, even during dynamic scenes or performances. High-quality transmitter straps prioritize comfort, allowing the talent to fully concentrate on their performance rather than being distracted by the presence of the transmitter on their body.


Placing a transmitter pack on a talent’s ankle is a popular choice for several reasons. Firstly, it is conveniently out of the way, ensuring that the pack does not interfere with the talent’s movement or clothing. Secondly, its location makes it easily accessible for technicians who may need to replace batteries or make adjustments during a production.

Using tools like the Lav-Bullet, Rode Mic Drop, or Lav-Rod can greatly facilitate the process of positioning the transmitter pack and routing the connector side of the lavalier microphone down the pants. These tools help sound technicians efficiently and discreetly secure the transmitter packs and lavalier microphones, allowing the talent to focus on their performance without being distracted by the audio equipment.

With the transmitter pack secured on the ankle, both the talent and the production team can experience a smoother and more efficient workflow, ultimately contributing to a higher-quality final production.

Pouches serve an essential function in keeping transmitters safe and secure during production. Rather than placing a transmitter directly into someone’s pocket, where it could potentially be scratched, damaged, or cause discomfort, using a pouch offers a more professional and protective solution. Pouches are specifically designed to house transmitters, ensuring that they are well-guarded and stable during filming.

Some pouches come equipped with clips, which further enhance their versatility and ease of use. These clips enable the pouches to be discreetly hidden under clothing, maintaining the visual integrity of the talent’s wardrobe while still providing quick access for adjustments or battery replacements. By using pouches with clips, production teams can ensure that their audio equipment is not only secure but also inconspicuous, allowing for a more seamless and professional production process.

In some instances, securing a transmitter pack to the talent can be straightforward by utilizing the belt that is already part of the talent’s wardrobe. This approach is convenient and allows for seamless integration with the talent’s outfit. However, there may be situations where using the talent’s belt is not feasible or accessible.

In such cases, standalone belts with built-in slits can be employed to hold the transmitter pouch securely. These belts are specifically designed to accommodate transmitter packs, ensuring that they remain firmly in place throughout the production. The slits in the belt make it easy to slide the transmitter pouch into position and provide a discreet, comfortable solution for the talent. By using these specialized belts, production teams can maintain a high level of audio quality while keeping the talent comfortable and focused on their performance.
