Meanwhile, in the news, there is another "Momentum" wireless technology that has just come out

But seriously, I should be getting mine tomorrow. I was a little disappointed when I learned that my beloved Galaxy Note 3 doesn't have Apt-X. So, at this point neither my laptop, my ipod touch, nor my phone have it. I also ordered the Fiio X5, and it will be arriving tomorrow, but it doesn't have bluetooth at all. I am not sure why Sammy took Apt-X out of the phone. So far as I have read, it seems as though it had it in the beginning, and was advertised on the back of the box IDK.....
After further looking, I see that the Galaxy Note 10.1 2014 DOES have it, so I can at least hear the difference of with, and without.
I bought mine from Sennheiser direct, and am getting the black. I really wanted to try the ivory, but I couldn't wait till mid Feb to get mine........ I am hoping they sound as good, or better than the original Momentums. I loved those, but think that the highs need more (just a shade too warm for me). Hope these are tuned/tweaked just a hair in that direction.
