guess what, unless your mouthpieces are made out of solid gold, in reality there probably each only worth about $10 scrap metal value.
These company’s have huge overheads, small scale production and have to make a profit.

If you can mass produce a product and got a huge market like sweets, then you can sell them cheap. If theres only a tiny specialist market that you are selling to like sax mouthpieces which is basically a metal pipe at the end of the day, to make a profit you have to sell it at as high a price you can get.

However, if you’ve got millions of cheap workers, you can undercut everyone.

cost of machinery to make product + cost of work force + cost of advertising + cost of materials + cost of premises ….

at the end of the day, it’s only a metal pipe, with a tiny market, so there’s no real reason a cheap mouthpiece cant outdo a more expensive one.

Some people will argue you sound the same on any mouthpiece, providing its not a dud.
