I understand your complaint, however most people that wish the speaker didn't automatically turn off aren't going to even consider buying a mini Bluetooth speaker in the first place. It's an pretty drastically different market. Heck, most people still don't even want Bluetooth, as there are so many limitations vs having a simple wire. Not only that, but clearly this Bluetooth speaker (and most others) are not meant for staying in one place and being plugged into the wall. You'll have to look elsewhere for that, and you'll find much better sound quality for a cheaper price as well... even if the speakers are old. Science tells us that it is inevitable you can get better sound in a larger speaker than a tiny one, assuming the other variables are the same. Unfortunately, more and more manufactures are making this tiny crap. Hope I can relate to you with this.
Anker - don't get me wrong, I won't pass up a Bluetooth speaker, preferably a larger one, though.
