Got mine from the same - german - store.
Could anyone test their Einsear T2 if they all have the same problem? Just plug them into your smartphone, start music, cover the mic and record for a few seconds to see, if they mic is also picking up output sound. Would be helpful to know, if every Einsear T2 has the same problem..
Tried this with my pair of T2. Yep, I confirm, the mic records what's playing. The volume is much lower than the original signal, but still it's there.
Got similar results with Urbanfun. Almost inaudible volume with Xiaomi Hybrids Pro HD though.
