The sound of my phone's has been improved with gentle songs, but most songs are too distorted, because of the bass, which happens to be the rule in Pop etc. Thus, I have to give a different buyer subsequently law.
A direct comparison with a Speed Trap Link Bluetooth adapter shows that distortions are uniquely generated by MOCREO Clipper.
There are also serious doubts about the battery power.
But why then 2 stars - because the device may be suitable for simple conversation transmission and thus for other clients could be interesting.
For me, the adapter is not to be used.
I am very disappointed.
Addendum 14.05.2015:
A new test with a Bluetooth transmitter TaoTronic gave a really unobtrusive reception without distortion. One can speculate whether the modulation of Taotronic station is less, but still it remains somewhat problematic when the recipient first needs to check for compatibility with standard per se transmission paths.
