A device that can deliver HD audio wirelessly to my speakers?

I have 2 macintosh laptops.
1 iPhone 5.

And need a way to send High Definition Instant audio from 1 of these to one of the other devices.

e.g mac to "mac (which is plugged into speakers)"
e.g mac to "iphone (which is plugged into speakers)"

but just in high definition and instantly.

Let me know how I can do this or what I have to buy.

The audio can be sent through bluetooth or Wi-Fi.

Will an external audio card help solve static noise?

I just bought a brand new Lenovo Thinkpad and I realised that there's static sound or maybe white noise sound when i have my headphones plugged in(ink'ed skull candy with mic) and it is pretty bad. I was wondering is there a way to fix this? The computer has good specs, i will post them down below and the headphone jack is on the right side.

Will buying an external audio card fix this problem? Or is there any other methods i could employ to fix this annoying problem? Maybe even configure something within the Dolby sound settings?
The headphones themselves are not it because they work fine on other comps and iphones.

What do you think?

Can I use an Iphone 4 or 4S with straight talk?

My friend is getting rid of his old iPhone and said he'd sell me it if I wanted it. Its on ATT but I use straight talk unlimited plan. I know you can get SIM cards from Straight talk for GSM phones and was wondering if I can do that with the iPhone 4 or 4s (Not sure which.Id assume it wouldn't make too much of a difference if I could or could though.)

Added (1). Also could someone link me to how to unlock it? IF ITS POSSIBLE
