Nah, I got the $50 earbuds (the black plastic ones) not the $150. The XB IEMs are $150 though.
I am still not sure if the OP meant IEM or conventional earbuds so I am just going on earbuds.
I haven't used the 980's but the TFTA earbuds have better bass than the MX470 IME.
Oh wow! I thought you have the older brothers :P My bad
I'm looking forward to some reviews then/comparisons :D!
