If you look at those Avantree transmitter, they only take analog input. That means your source (a DAP, PC, smartphone or even a TV) has to do the D-to-A conversion first, send the analog signal to Avantree, go through another A-to-D, send to the receiving end (a BT headphone or something like the Creative E5), go through another D-to-A. Now the problem is, the signal has to pass through 2 DAC and 1 ADC, so SQ will definitely be degraded for sure. Even worst is that we have no idea how good the DAC / ADC used in Avantree.
Anyway, if you have a BT headphone, you don't need the E5 / X7 unless the DAC and amp section inside the BT headphone is significantly less quality than E5 / X7.
Qualcomm bought CSR (more correctly, is "in the process of buying"). Since CSR owns aptX, Qualcomm owns aptX as well.
And what exactly does this e5 or x7?
What if i use a dongle? The digital signal stays digital all the time from the pc till the headphones right? Should this be better?
Because i didn't notice any difference between the sound i got with Sennheiser dongle or Avantree adapter...
