Im wondering if its the GHz interference thingy, how come when I used my phone from the same location theres no crackling?

certain frequencies are reserved for certain things. cellular seems like it's using a wide variety of frequencies that are less than 2GHz (with the odd one being above 2GHz). bluetooth and WiFi are both specifically using 2.4GHz (which really means something like 2.40-2.48 GHz). I don't have any direct experience with them interfering, it's just what comes up when researching this.

it may also just be coming from your PC directly. I know I've used a lot of computers where you could hear mouse movement and hard drive activity in the sound system, for example.

(one thing I wonder is how bluetooth would pick up interference if it's a digital protocol. I don't know enough about the protocol to know one way or the other, but it could mean that the interference is only present at the analog level, which I guess would be in the earbuds/headphones themselves. but I don't know and have nothing to test.)
