Is there at least an online article which addresses my questions?
I can't believe how impossible it is for me to find out answers. I feel like a Martian - i.e. nobody else seems to have the same questions I do.
Before shopping for an MP3 player & speakers, I've been trying for the past few weeks to find out the following:
If an MP3 player is connected to powerful speakers or a powerful speaker-dock, does this drain the player's battery quicker than if just connected to earphones?
Are there no MP3 players that run on 9V battery or with power adapter? I.E. wouldn't that last longer than those powered by AAA batteries, yet be easier to replace than a lithium-ion?
Basically, what I'm wanting to know is:
If I mainly want to listen to music at home, there's no sense using up battery (how many times can it be recharged before finally going dead?)
Is it possible for the MP3 player AND the speakers to SIMULTANEOUSLY get their power from a wall outlet via power adapter, yet be connected to each other as well?
I know there's also MP3 CD players - but I believe those just show track numbers and don't have a screen.
