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.

Simple fix, works perfectly!

This adapter absolutely does the trick. I wasn't getting any signal at all with my setup, but as soon as I put this null modem adapter in, everything started working instantly. It's a very simple plug-and-play solution that just does the job perfectly. Highly recommend if you're dealing with serial communication signal issues! It even comes as a two-pack. I only need one, so I'm not sure what to do with the other now.
