There’s quite some Hama branded products in the German (real-world) stores. They do the cheap or price/value option. Mostly accessories and consumer electronics for phones, computer, photography.

I don’t know if that concept translates to online stores, though. In real-world stores they provide the cheap option. Of course their stuff is 99% Chinese-made but there’s some brand recognition with Hama so you’ll know you’ll get some cheap, but somewhat working headphones. And with online-stores there’s a plethora of options and everything is cheap. And you can see reviews and a score, sort by price… So I guess you could just buy arbitrary things with a good cost/performance ratio, maybe better than Hama does, just that somebody else imports it from China. So I don’t think slapping their label on products helps there. Their products just don’t stand out, especially if people don’t have any brand recognition in the first place.

(And what other people said, here. Consumers don’t really care for brands on their cables, supplies and phone cases. And if they do care, they’re part of a different market segment. They’ll pick something better, not a Hama product.)
