Is it possible to add battery and make wireless device for music use?
Is it possible to add battery here – to make wireless airport for music listening by Apple's Airplay (Wi-fi)?
Bluetooth is awful for music with no quality at all until we get someday 5.0
I noticed that Apple's airport express is getting hot during operation, maybe this problem can be managed with getting rid of converting power supply (battery direct needed voltage).
Is this a good question?
