The gooseneck mic extensions are extremely sturdy and have actually only been made use of a couple of times.
A chronic trouble with low-cost mic extensions is that the longer the extension the more the weight of the mic makes it sag or droop.
You begin with the mic placed properly and slowly it starts pointing towards the floor !!!
There is absolutely no droop in these. Set your mic and it will stay.
$12 each or $20 for both.
