I received them today. Some pics and out of the package impressions...
First, they are the older version. Nice accessories. Better quality construction than this price level for both the phones and accessories.
I like their small size and short bulb stem; you can wear them straight out or over the ear equally well. Very little microphonics when worn over the ear. They can provide nice isolation depending on how deeply inserted.
The out of box sound is bassy with some bloat, nice forward mids and some pretty smooth treble. I know I have the old version but I expected worse. EQ-ing the bass down a bit fixes them up nice. Either burn-in will kill the bloat or opening up the back port will help. I am going to burn them in first before I try to mod them. Stands to reason the larger port should tighten it up letting air flow better.
Anyway, with the bass reduced the overall sound is smooth and musical with some nice weight. I hear a nice level of detail so far and some nice seperation. The soundstage is a good size in both height and width. Decent speed and can handle fast, complex drums quite well which is a good sign for me and my music tastes.
I have played with some different tips. I like my red ebay EX71 style and also the E2c soft flex better than the stock tips. Better sound with these. May have something to do with the stock tips small size. I would say the medium is smaller than any other style mediums. Now checking the large size, I see the large is about the size of other companies mediums. I will go back and try the large. They are shallow tips for sure. The large is 7mm long which is 2,3, or more mm shorter than the other large tips. Ah yes, now thinking the large stocks might sound the best. The shorter tips seem to help the soundstage.
There is some nice driver flex to be heard. Even more with the longer tips. I feel the need to be more careful with them. The lifetime warranty is a good thing. They are in Vancouver, Washington for those in the US this is a good thing.
Just out of the box impressions but they seem to be a really sweet deal for $30 or less. If the new version goes up to $49 I would still recommend them. Not an absolute steal at that price but a better package than most of the $50 canalphones out there.
PK2/UE3 comparisons coming after getting more familiar with them and some more burn-in. I'll also probably have decided on opening up the port and see how that turned out.
