I've been using these for 2 months now, and I'm really happy with them.
Extremely confortable for side sleeping, they replaced my former T-Jays for the night and naps. I wear them cable down, but sometimes i need to put the cable up / around the ear on the ear I sleep on and I just dont feel them. As confortable as the soundmagic PL50 was, but with bass and a smooth signature !
I use the stock medium tips. Tried a few others, including hybrids, but found the stock tips to be the best. They are a little more rigid and bring the best bass. Isolation is also very good with stock tips (but less with other tips).
The cable makes a little bit of noise when wore cable down, so it's not that nice when moving. But for home use, it's really fine (and a lot better than then rigid re-400 cable).
Comparing the sound to other iem I used (as i can, i'm no audiophile) :
As smooth as re-400, with a little more bass, and a bit more power in the upper mid range (but not to the point of being unbearable like the pl50). May be a little more space/soundstage, i would put them between the re-400 (intimate) and the Philips Fidelio S1 (spacious).
Less bass than the t-jays I loved, it was quite a bit of a shock when I switched from the t-jays : the music had a lot more clarity, air and space, more enjoyable (now, I'm used to that and the surprise is gone).
Would love to read more reviews and technical comments about their sound.
