What i think i am seeing in the picture is two different converters. is one a straight through gender changer & the other a null modem configuration?

Both of them are standard null modem adapters

Will these pass sound so that I may plug in my Bose speakers?

not sure your application, this is an RS232 signal swap adapter. Here is pinout: pin-1 goes to pin-4, pin-2 to pin-3, pin-5 to pin-5, pin-7 to pin-8, and pins-6&9 are not connected.

Hi, are both of these the exact same? If not what is the difference?

I ordered a 2 pack for work and they are the same.
