I'm looking for a speaker, Bluetooth preferred, Aux-connected acceptable, for an Echo Dot.
My intent is to have it boost the audio (both to increase the volume and the sound quality) of the Dot. It's going to remain plugged in all the time so I'd prefer it not be battery-powered. I'm not against battery power but I won't be using it, so a rechargeable battery will be wasted space and expense. Is there anything out there that fits this, or should I resign myself to getting a portable speaker that has batteries?
(FWIW, a Bluetooth stereo adapter wouldn't be practical.)
