I've been using these for the better part of the week now, avoiding all my other buds. Why? Great question. I don't know.
After probably 100+ hours of use, I have to say they are a pretty fun IEM. I much prefer them to the Panasonic RP-HJE120 which were my previous sub 10 CAD favorites. I would take them over the JVC HA-FR201s any day of the week as the treble is no nowhere near as uncomfortable, I prefer the mids, and while they cannot produce the deep bass of the 201s, they keep up pretty well. The UE100 I have are the most boring IEMs I've ever listened to, so these are miles better IMO, even if the UE100 are technically stronger. I even set aside my new Sony XB50s...
These really shine at high volume, which is not something I could have said earlier in their lifespan. Despite having significantly recessed mids and highs before, these babies got harsh when blasting it. Now though, they sound pretty darn solid. You could argue this is brain burn in (certainly part of it), but I really do think these things have gone through a midlife crisis and have matured into a decent all around IEM.
I mentioned in another post that some high notes would have a metallic tinge to them. Gone. The bass used to be overpowering. Now that they seem to have developed the ability to produce mids, the bass is perfect. Nice and punchy. Guitars no longer sound like they are playing in another room. I am also constantly surprised by how deep the soundstage is. Listening to some internet radio at work today, a song came on that had a distant voice call out. The first time it happened I took out a bud to see who was speaking to me. That's only ever happen with my FXT90s.
The best part? They are foolproof for getting a good seal. Just jam them in and you are good to go. No driver flex either. I don't know what kind of cheap arse rubber they are using for these tips, but it works wonders. You can shake your head around like some crazy possessed hell spawn, and they stay put, but give them a solid tug and out they slide. No popping of the ears. I love it.
I kind of want 'nick n' to pick them up just to see how he feels after giving them some time to burn in...at the very least they could work as a donor housing (as he suggested earlier) if he could rip em apart safely. Would be interesting to see the size of the driver. I'm guessing somewhere between 8-10 mm.
I was also debating buying another pair just to see if above is all bullpocky and they really haven't changed any. There is one set left at my local Superstore...hmmmm.
