Based on your impressions, I'd recommend you try out the Shure SE215 if you do want to have something for active/outdoor listening; they really aren't leagues behind top-tier IEMs the way some would let you believe, but they are a definite step up in overall clarity and cohesiveness from the Bose IEMs, with tighter bass to boot. They have the same fit as the 535s which you seem to like; give them a shot :) You can even get them with a mic/controls for your iPhone for about $150. I love mine; IEMs come and go through my hands, at least 7 or 8 pairs a year, and SE215 is the only one that's stayed, and it's been here from day 1 of my headphone journey. I have a TF10, which most folks here would say is much better than the SE215, but to my ears it is only a bit better, mostly in terms of treble and soundstage. IMO the SE215 has nothing to be ashamed of, especially at its price. If you like the sound of the Bose and want something a bit better, and you liked the SE535's fit, it might be the last one you ever buy :)

Comparing them to $120 Bose IEMs ..... Shure 535, Westone W4 and HiFi RE600 are not 4 times better than Bose IEM .... nor are they 3 or 2 times better.
Westone sounds too weak. Reminds me of Grados SR225 .... lots of treble, little bass, I tried to get used to the sound but ... those are not made for smooth jazz or classic .... seems like they are more for rock, heavy music ...
Shure 535 ... nice, nice fit, nice sound, not $400 nice, at least for me.
HiFiMan RE600 ... some things better than the other two and some other music Shure is better.
Bottom line .... not worth for me to spend 3-4 times as much as my current Bose IEMs cost.
I also compared these to my Open HD598 over ear headphones .... with no surprise those beat all of the IEMs for me. Much, much bigger sound-stage, just enough bass .... no $400 IEMs for me. :-)
One guy on this forum once said that once you upgrade from those cheap $20 headbuds to something like even Iphones $30 IEMs, that's where you'll see the biggest sound difference. Difference between a $100 and $400 IEMs .... not that big compared to the price.
