A quick check in. I'm finding them to have a very open & natural sound at the moment. Treble not too sharp. Although I'm far from being a Bass-head, I could do with a little more bass. However, I think I'm going to have to go back to the office to get a bit shaved off the bit that goes right inside the ear. The right one in particular is quite painful, particularly when I completely close my jaw. The left one also, but to a much lesser extent. I hate to think how uncomfortable they would be if they were acrylic! I'm guessing that the Bass would improve if I could get them in further without the discomfort. The cable is very well behaved, not snagging or getting tangled. These are my first ever IEM of any description that I'm in any way happy with, as I've never been able to get universals that fit my ears at all, so I realise that the soundstage etc will be different from what I'm used to ( B&W P7's). So to summarise a this point, I'm very pleased with the sound overall, but once I get the comfort issue solved I'm hoping that the Bass will spring out a tad more. Also, with the discomfort there is no way that I could wear them for more than an hour at a stretch at the moment. I also have a pair of Pro 17 ear plugs on order with ACS, so I'm waiting to see if they have the same fit issue, so when I get them ( & got over my cold) I'll get myself back to their office. So not the 'WOW ,they're AMAZING' that I'd hope for straight out of the box, but I have hope that we'll get there with getting the fit better. I'll let you know how I get on.
