Means for proper quality / price ratio (the poor sony at a fair price)

After purchasing 4 "Creative EP-630 in-ear earphones" (15 to 25 euros depending on the moment), the first three were of excellent sound quality, I turned to these "Sony MDR-EX10LPB" since comments seemed to put them first.

I stopped the "Creative EP-630" because their quality drastically chutée. They became "low end" without the price will follow. It has been observed by many people, they are no more than the pale copy of themselves.
When these headphones have fallen further down (4 in 5 years, always the same problem of the right earpiece which loosely) had to change.
I turned to these "Sony MDR-EX10LPB". At 12 euros I was not expecting much, and that's what I got.
For spoken only sound: the sound was good to 12. The bass is too present and cover the midrange and treble, giving a slightly twangy sound without much clarity. But nothing alarming for listening that I have. (Walk or sleep)

The "Creative EP-630" first generation were much better (but they no longer exist). When their "copy" current, it is equivalent, but more expensive.
So in the end: who does not expect to have "Shure" to 12 euro, buying is very correct.
