I just tried z5 at the local sony store last week. The bass is quite impressive (much better than my ex1000); however, treble and mid range are quite a let down for an iem at this price range. In comparison to xba h3, z5's sound is more balanced and z5's bass is better controlled.   I will...

  I also heard of similar cases from several ACS owners in my region. In the end, the owners sent their T1s back to ACS to get them fixed. ACS team stated that the problems were from defected T1's driver.     In my case, this is my second cable which I bought in June 2013 and only used it...

Yes, I have already tried that; however, it partially solved the problem. I still occasionally can't hear any sound coming from the left monitor.

Just got my ACS T2 back last week. The total cost is around 333 USD. It took me approx. 100 days to get my T2 back.   According to Jaben, there was a miscommunication between their staffs, and that's is the reason why it took around 3 weeks for them to send me back my T2.     However, my...

Just got this little beast from my dear friend who just came back from Japan.  

  I checked with ACS a few days ago. Their reply is that ACS has repaired my T2 and  sent it back to Jaben on 29th November. This is quite surprised since Jaben guy told me (the day before I contact ACS) that he did not have any update regarding my ACS status. As for the cost, Jaben has told...

Now, 86 days have passed. I still have not heard anything regarding my ACS T2 Status.

I just demoed F886 from one of headphone stores in my country. The sound quality is clearly better than my walkman Z in 2 areas, namely; soundstage and instrument separation. Now, I can't wait to try ZX1. I wish I could buy ZX1 from Japan this year but I can't due to my financial reasons. Σ(´д｀;)

Well, if we use the announced F886's price as a reference, Thai's ZX1 should be approx. 15-20% higher than Japan's. However, the previous Sony Thailand pricing shows that most of their products are approx 30-40% higher.

I also have an unpleasant memory with ACS build reliability and speed of service. I ordered my ACS T2 from Jaben in the beg. of Feb 2013, and recieved it 2 months later. I was very happy with the sound quality; however in June the cable somehow was malfunctioning. I asked for a replacement...

According to the best available information, one of the countries, which will release ZX1 in Feb 2014, would be Thailand.
