The are not an earphone I would walk around with as they can easily drop out as there is no friction holding them in, just the weight. I think the only thing I would change in a way, though I wouldn't as I have found a way around it, would be for the finish to be brushed instead of polished as I think they would be a little more secure. Having said that. My little trick that works wonders is to wipe the inside of my ear with denatured alcohol, not only does it prevent ear wax build up but it gets rid of any greasiness and I find then the PF"s stay solidly put.
It sounds like a lot of effort but I always clean my ears before putting in my IEM's so it is no different.
I can sit in my chair with my head back and they stay put but I have yet to have success laying in bed with them, they fall out each time.
For me what you get with these is an amazing sense of the musical performance, the best soundstage I have heard with a headphone.. Any headphone including the Stax SR009. It is funny as when I first got them I thought they had no soundstage or bass to speak off but once accustomed to the way they deliver music I feel they want for nothing, great, fast, detailed bass, mids to die for and such a sweet and delicate treble. You would think they would only be good for real instruments (which by the way they are truly memorable with ) but they do electronic really well as well.
I think the way I feel about them is that they are a grown up headphone, they do not seek to impress with bells and whistles, their only desire is for one to be immersed full into the music, forget it is HiFi and just engage with the performer on a one to one basis.
Oh yes, and as for transparency, I have heard things with these deep in the acoustic that I have only heard with Wilson speakers and a Nagra amp/cd set up, not saying they are in that league if you know what I mean but they are able to convey similar detail retrieval and emotion.
One last thing, for me they are the most comfortable earphones/ IEM's/ Headphones I have ever worn, zero fatigue and unlike ones with silicone tips your ears don't get itchy after a while or hot.
