If those are the ones, I'd still be confident you'd be better off with what you've bought. For the Sennheisers at least. I have a galaxy s3 that I got while my klipsches were still intact, and those came with these I'm pretty sure. I tried them out, then gave them to my little brother (he was thrilled lol). Much better than Apple's garbage earphones to be sure, but...that's not exactly setting much of a high bar, more of about the waist height bar used in the high jump in Nichijou (with the Apple earbuds going Mio and either going under the bar, ramming into it, or shooting parallel to it).
AIso, isn't a flat sound supposed to be good? Or...
I guess moderate flatness may be not so bad for some people but clear lack of bass can be quite dissapointing. Of course a lot of them can give you a headache(like both of my Koss), so I hope to find earphones with a good overall balance, where a little tuning with equalizer can make them suitable for a wide range of music genres. Maybe I'm hoping for too much for earphones under 50$, but with so much different models available the probability finding the right one is quite high.
