I always had AKG K 324 P, great price (between 20 and 25 €), great sound (shaking bass really), then they disappeared from the market and I lost the last pair I had.
Same price range, also great bass - Creative EP 630. The following EP 660 are even better but so cheaply crafted, they break very easy.
I´m now having LG Quadbeat 2 which came with my mobile and they are surprisingly good for stock headphones, so I´m keeping them. Price about 15 €, more likely less.
In ears are always a bit of hit and miss. You can have cheap ones, made in china "no names", that you have never heard about before but actually sound awesome.
Then buying something like TDK or JBL that sounds shit. So many of them on the market it´s a pain in the ass.
