I  *once*  owned  some  good  in-ear headphones. Of course, they broke
 after some years. I never found headphones like that again. They  were
 some cheap ones, I don't even know the manufacturer.

 Today,  I  bought  a pair of Sennheiser MX 271. Boy, that's what I was
 looking for.

   1.  Only 10 euro.

   2.  Reasonable sound quality. They aren't studio headphones but they
       sound good. No "tinny" crap.

   3.  Comfortable  to  wear.  It's  a "special design" for small ears.
       Well, I guess they're just some millimetres smaller than regular
       in-ear headphones.

   4.  A  black  cable.  Why the hell are there so many headphones with
       *white* cables?

   5.  A long cable.

   6.  An angled plug.

 I guess I'll buy some more tomorrow. Just in case.
