Women in general don't seem very interested in technology (excepting cell phones). My girlfriend would far prefer jewelry, shoes, purses and makeup. Half of her opinion of earphones depends upon what they look like. For me that's all well and good; I accept that the sexes think differently (far beyond socialization). In the past women entering into male dominated hobbies have often resulted in negative changes to the hobby overall (i.e. Twilight being considered a horror book/film).
totally respect their own hobbies, and at the same time, i am kinda glad that they dont know too much than just how it looks, otherwise they would know how much i am paying for each iem/cm/headphone/cable and get even one way or another
