Crystal clear sound 2

I personally use these headphones to go running with a source shuffle Apple.
I am satisfied, they hold firmly in place and do not isolate
too from outside.
The sound is very clear, especially for middle and treble very "detailed".
I expected a little more bass deep, but it is quite acceptable.
These headphones are well worth the more expensive headphones and often less comfortable to wear.
I also appreciate the angled jack connector which limits the length of the source, when connected.
In the end, good buy.
