Just got them today in the mail.
Initial impressions, pre burn-in, out-of-the-box, with default tips:
1) Same old bad to open, good looking packaging that makes me feel like they don't want me to get into their earphones like other makers
* The cord is quite microphonic as others have stated and even still a tad microphonic if worn around-the-ear. 2nd/3rd most microphonic cord I've heard behind the microphonic king, the Sennheiser CX300 and the iM716.
* Laid-back sound signature, however not as laid back as the Jays s-Jays. The s-Jays are about 6 rows back, the ADDIEM 4 1/2 rows back, the NE-7M about 3 1/2 rows back, the Denon C751 about 1 1/2 rows back. I prefer my sound signature not as forward as the NE-7M but not as laid back as the ADDIEM so I still haven't found the perfect earphone in this aspect
* Focused on the mids but surprisingly good tight bass, particularly considering it's pre burn-in. At least it was much tighter than the s-Jays at the same stage of burn-in, which suffered from uncontrolled bass pre burn-in (tightens up with it).
* Clarity is the best of any sub $100 IEM i've heard (And I've heard lots, see my sig). Sure, the Head-Direct RE-2 could be argued against this, but I feel the RE-2 is significantly more coloured sounding than the ADDIEM.
* ADDIEM + well recorded music (e.g. old Rush, Porcupine Tree) = makes the earphone really shine. Detail in the mids = the best out of any sub $100 earphone.
The ADDIEM isn't super detailed however it is no slouch either on this aspect.
Soundstage and instrument separation: I'm mixed about this. However, thing is with good sub $100 earphones, all have their unique soundstages. the ADDIEM's soundstage is still 'in-your-head' (the NE-7M is the only earphone that has a feeling of 'outside-the-head' soundstage under US$100 I've heard). What unique about the ADDIEM is that the 'behind the head' aspect of the soundstage is more evident than other IEM's. It's not as wide as the RE2 but in terms of overall 'rounded' '3D' soundstage, the ADDIEM is best in this aspect under US$100.
Instrument separation is interesting as I find this is a weak aspect of the ADDIEM. it just doesn't do instrument separation well. Apart from the drums, which are recessed at times, the rest of the instruments are to either side about 20-30 degrees from one another.
Otherwise, yet, the ADDIEM are worth the price of admission.
Let's see what happens with a bit of burn-in over the next few days.
