Muahhh ... they do have their place at high elevation and single digit humidity at 100 degree F outdoors where you need to have a lawn sprinkler blow in your face to keep the reed moist. Unfortunately some of that stuff is non-potableFor me plasticovers are all stuffy and dull.
I've wasted money on a couple of boxes and every single Reed was hopeless.
So at least they are consistent.
There's a bunch of guys who swear or swore (RIP) by them. I don't need to list all the top tier pros using them. We all know who they are.Are those the black plastic coated reeds.
If so the break in is easy. Break ever reed in half and buy something that doesnt sound terrible.
Even the cheap chineese cae reeds sound better and they are junk.
A guy came to my shop play testing every oiece I had. They all sounded horrible...if I made pieces that siunded so bad I would have been out of business 15 years ago. He had one good cane reed in his case. He put it on when i asked an he sounded fantastic.
There are a few pretty good synth reeds...those are not.
Its like making love in a raincoat.
