Plugged in a soundbar mounted across room from TV. Poor sound and mic quality and overall product is not at all as described in description The inside measurements are 22&1/2 inch Wide and 10 & 1/4 inch deep the inside height is 6& 1/4 inch on the front and 4 &1/8 inch sides and back. Doesnt need an outlet. Saved by the back strap though. Feels more nylon than Sherling. Ging Retoure. It isnt that complicated so I bought some bolts at Home Depot and figured the assembly out from the picture. I have six bikes that I use same computer on. For mastering, this can lead to too dull a result, especially in vocal clarity.
