There are four obvious technical errors in the following paragraphs from the Von Schweikert technical description of the MasterBuilt Ultra Speaker Wire. Grammatical errors don’t count. Get all four right and win a prize."

It reads like someone from the Department of Transportation tried to make a joke. Electrons making screeching noises when jumping curbs or colliding with other vehicles. Some of them carrying heavier loads, some lighter, which makes braking performance different.

I wonder how far would this go, how much would it cost, if someone approached the company and asked for upgraded cables in a Walkman. Let’s say, whatever little wire is there to be upgraded. Maybe, while they are at that, even ask them to design a better headphone jack. What number would it be for that custom project? $10 000? $117 000?
