I bought these IEMs a couple of weeks ago (no Sony Ericsson logo on the rear) and I'm quite satisfied with the sound quality.
To my disbelief, since I think it is an OMTP device, my Samsung Player 4.2 is compatible with all of its keys except for the Smartkey, of course. Nonethelss, I'm a little disappointing with the quality of the recordings through the microphone, because there's too much static which - I found out - can be heavely reduced when I hold the Smartkey. The same applies to Skype and to any other applications where the use of the microphone is involved. On the other hand, I tried the IEMs on my oldish and cheap Huawei Ideos U8150 and, inesplicably to my knowledge, the receiver hears no static during the conversation nor is there during recordigs.
So, my question is: do you think that if I buy an CTIA to OMPT adapter that will be able of reducing the static?
