@GregBe For most people, excessive bass in an earbud can only be achieved through heavy EQ. One of our basshead members for example would push around +26 dB, where I believe I'm pushing maybe +20 dB (not actually marked on Opus #1 so those could be .5 dB steps) plus ifi XBass. And even then, I wouldn't call it excessive, just fun.
Your sound signature request should be easy enough, although I've mever heard the example can, but in-line controls can be rare unless we're talking detachable cable. I'd be inclined to suggest Rose Technology Masya as it has respectable bass, lovely vocals, non-murderous treble and a detachable cable (.75mm 2-pin annoyingly enough) but last I checked it's a hair above $100 at I believe 109 or so, and some people have fit issues which might affect work-outs.
My favorite over-ear detachable cable warm sub-100 earbud is the Svara-L, but soon after release it was changed from a 115 to 32 ohm earbud for the sake of phone-friendliness (or at least that was my understanding) so cannot currently comment on the sound sig or quality, but others here did buy it as this iteration came out. Also, given your in-line requirement 115 ohm might be too much for your source. Hopefully someone can chime in on the other version. I've heard some rumors the bass was tamed, but cannot confirm.
If you're not needing the top quality sound available, there are less expensive options like the 1More EO320 which meets your bass & control requirements, has a sturdy construction, a reasonably enjoyable sound with enough bass for most, and hopefully can stay put for a work-out. There are also reports that the new version of the **** PT15 (which originally were my treble-head budget recommendation) were given a bit more bass to fix the somewhat anemic nature from before (I should give this a listen as the quality for the price on the original was actually really quite good) and might also suit you.
If other recommendations come to mind, I'll let you know.
