I actually used this for the thomann own brand wireless in ear monitors.
The main box goes right into the padded slot and fits nice and snug. The bag does have a slot for a wireless mic, but this is where i place the body pack and again fits nice and snug with plenty of padding.
Moving to the back of the bag, theres plenty of space at the box for the power adaptor, which is great leaving it plugged in.
And the best part is the zip on the top of the bag, which un zipps right where the rear ariel sits. You unzip it and then place the ariel upwards! what a great design, they really have thought it through!
Great lightweight wireless bag, with alot of padding
