Good quality 715

The audio quality is good enough for that price, even though it is certainly not that of more expensive models. The sound insulation is good, although the wire is 1.50m and looks solid (it has not broken in three months while I fold it in every way, the bottom of a backpack, several times per day). The weight remains correct. It is large enough to cover the ears.
Personally I use it every day in the Paris metro and it is perfect!
