Never heard the IE6, but the S4 have a lot of bass, but highs are bad, recessed.

Alright they had about 3 hours burn in now with white noise, pink noise and frequency sweeps and I must say they sound amazing the bass is really deep and punchy and tbh in Techno/Hardstyle I don't feel like they lack in the highs. These ear-plugs are just genious! Although I think the wire is a bit thin but alright

. If you listen to trance/dance/hardstyle etc... these are really good for the price tag

. Thanks Head-Fi

Heard them both, I wasn't a fan of the S4s; I found the bass to be a tad boomy, the treble somewhat metallic sounding and the midrange slightly too recessed for my liking. The IE6 has a good bass response, fair mids and acceptable highs. If I had to go for one over the other I'd take the IE6...
 
Saying that the horse has probably bolted as it seems the OP has already gone for the S4's

The IE6s are very Bassy! Not allot of Highs.

I love the S4s for electronic music!  The highs are just fine
