I just received mine from Amazon UK, sold by a vendor called total digital stores.
Ordered on Tuesday afternoon and got them here in the Netherlands on Saturday (today) at 2pm.
What comes in the mail. The headset up close
The tips they come with (photo is of the largest pair)
Build quality is acceptable to me, the jack and housing are pretty rugged, and the cable doesn't give me cause for much concern (other than comfort, which I'll come to in a moment).
Wearing these, I don't feel like the housings will come loose as I made sure mine are seated quite deeply, (not as deeply as the HF3s with triple flanges of course). I used the default tips on both sides.
The good news is that mic controls work flawlessly with my Samsung Galaxy S3 (save for the smartkey). I think mic quality is about average. I recorded my voice on the galaxy s3 using skype's call test service and the sony headset sounds clearer than the default microphone on the samsung phone. I still can't quite get used to the height of the mic and controls though.
comfort and microphonics is improved when using the shirt clip as well.
I can't really describe sound well, so take what you read with a pinch of salt.
I own 3 IEMs other IEMs; a pair of Etymotic HF3s which a fellow headfier very kindly shipped over to Netherlands for me when they were on sale in the US (the infamous cowboom.com sale) a month or so back;a pair of Vsonic GR07 mk1s (didn't bring them with me to Europe); and a Nakamichi NEP S800 IEM. I'll make comparisons with the first 2 as the Sony seems to outdo the Nakamichis in every way.
I've only been listening to these for 1 hour, but sound quality is undeniably good to my ears.I can see them complementing my HF3s as these immerse me in the music more. Hearing these makes my HF3's bass sound slightly anemic and less satisfying in comparison. It reaches low with ease (with more quantity) and it does remind me somewhat of my GR07s in terms of sound signature compared to the HF3s. These are definitely a better fit for listening to eurobeat or trance than the HF3s. I got a nice surprise when the bass kicked in as listening to eurobeat got my heart pounding again.
Soundstage is about as wide as the HF3s, but losing to the GR07s slightly. However, these do better than the GR07s in portraying depth. I'm currently listening to The Police on youtube (vinyl recording of "every breath you take" recorded on a USB turntable) and you can feel clearly that the rhythm and bass guitars are much closer to you than the singer, and the drums are somewhere in the back (off centre and more to the left side?). Cymbal crashes are more satisfying on the GR07s and HF3s to me. These sound more fun than my HF3s as well.
Lastly, I needed to turn up my laptop volume from 4 to 8 to listen to these comfortably compared to the HF3s. Strangely enough, I only needed to turn up the volume by 1 click (2 to 3) on the galaxy S3.
In any case, they remind me enough of these top dollar (and widely acclaimed) IEMs that the value proposition is undeniable. I will really call it a diamond in the rough so thanks to Tai for unearthing these gems and helping us give them the attention they deserve.
