no idea...i din find any result from the pos laju tracker..also hoping to get it 2day...sigh...cannot go out..

I receive mine already, but sorry to say I am not really satisfied with it, I was expecting for it to be better however,

the headset HPM-82 (3.5mm headsset) from sony ericsson sounds better, more bass, solid noise, the sound has more BODY!

For this, it seems that there is some noise in the background and treble is high, lack of bass no matter how deep i push into my ear. I've tested it in several phone, mp3 player, and pc. Now what I need is to burn in and see if there is improvement or not.

I thought quality is that good where getting so many good comments from buyers, and seems like some buyer first time use noise isolation headset (no offence) and don know how to describe it.

Just my opinion though. no hard feelings
