Slapping one together out of spare parts is not at all the same as mass producing one in a factory.

And whatever you could slap together for 30 bucks would, as I said, in previous comment, suck and break very easily, not to mention that you wouldn’t be able to bring it anywhere close to the ocean for fear of everything corroding extremely quickly.

Probably because it would weigh 40 pounds and cost $1700. It would probably also suck, and break very easily.

And having any of that shit anywhere close to saltwater? Hell no. The electronics should be corroded within a week.

Edit: while we definitely have the technology to do this, we just don’t have the capability to mass produce them at a reasonable price or of any reasonable quality. Current technology and materials also come with a lot of really crappy limitations. Maybe something like this might get developed if a lot of people suddenly show interest in it, but aside from that happening, it could be a while.

Developing a product like this could take hundreds of millions of dollars and 10 years to get something like in the picture above.

I had one of those. It was a great sound card.
