Given my research over the past couple of weeks, I find myself drawn to the (perceived based on what I've read anyways) sound sig of the 1964Ears V3. I'm also attracted to its price & customisation options.
So far as universal IEM's go, over the past two years or so I've used (extensively) VSonic R02Pro2's, Brainwavz M3 & Brainwavz B2 (Also CX300's when I've been inbetween better IEM's or they've been broken/returned, but don't tell anyone. That's my secret shame
). I've liked all 3 of these with their very different sound sigs & 'quirks'. I've probably most enjoyed the B2's I've been using for the past 9 mths or so because they've been so different to what I've used previously; detailed (relatively speaking, obviously), nice soundstage, punches above its weight value-wise (so other people who have heard IEM's further up the foodchain tell me). Not lashings of bass, but what is there is quite detailed, 'agile' & not muddy or boomy.
I've settled on my Cowon X9 as a source at least for the time being (tho will be looking to upgrade later this year) having previously used a Creative Zen Vision M & then several smartphones.
I'm obviously open to any suggestions other than the V3's, but as I said I'm attracted to the sound sig. Tho I've very much enjoyed the B2's & their sig, I like the idea of the V3's having that slight emphasis on bass, but with much emphasis on the mids, with highs rolled off a little with a somewhat 'natural' sound rather than a really neutral/analytical sound.
Anyhow, thanks again for all the time & effort you've put into this thread, and for all the help you've given people like me along the way
