Testimonials

A great, comfortable & discreet option for talent wearing IEMs that prefer not to clip onto a belt or may want a more secure solution.In addition, almost a must have for filming sports/fitness content. Will hold a transmitter pack in place very reliably no matter the body movement, whilst also being very comfortable for talent.Will even have use when micing up an actor wearing a crop top or similar costume that wouldn't allow for a usual transmitter placement on the waist.

I have purchased and used many Ursa products before, primarily using the pouches to attach packs to clothing. However, I have found that when attaching them to women's bras, they can sometimes be uncomfortable for the wearer. The back strap, on the other hand, securely holds the pack in place, reducing any noticeable bulge through clothing and giving the talent more confidence that the transmitters will stay securely attached.

I’ve been an actor in live theatre for most of my life. I’ve always hated the bulky mic pack belts that give you that weird hump at your waistline. This solves that issue. Fits between the shoulder blades and is very lightweight. I’ll never go back to the old mic pack belts.It’s a bit tricky to remove the entire mic from the pocket in a hurry, but it’s quick and simple to access the element and switch that out. Worth the price.
