I am very curious on the SQ on these cans, I think A2DP (Advanced Audio Distribution Profile) uses GAVDP (General Audio/Video Distribution Profile), which could use several lossy codecs like SBC (subband codec), MPEG-1,2 Audio, MPEG-2, 4 AAC, and ATRAC (the evil Sony MiniDisc codec). So my lossless tracks will get compressed when streamed over A2DP, but these IEMs are probably not good enough for me to notice the difference… I will have to try these babies out, and if they work well enough I’ll use them as my running cans… 🙂

I’m sure there are already a bunch of threads on HeadFi about these but I am too lazy to go look…
