Hi everyone, newbie here. I work for a small company who is concentrating on designing&making hardshell backpacks. This year our designer came up with an idea of making a backpack with bluetooth speakers (built-in rechargeable battery), we are all fancy with its sleek look and nice sound quality. Here is the thing, our boss decided to produce around 200 of this backpack and planned to launch it several months later. Personally, I’m not sure about if it could get an expected market feedback. Could you tell me your opinion? Like, do you like it at the first glance? What other functions do you guys need when using such a hardshell backpack?
