I heard some music coming from my brother's 3DS, and it sounded somewhat tinny (like it was too loud). I played the same music on both mine and his 3DS (it was the music from X and Y from the mushroom town) and noticed a distinct difference; mine sounded smoother (if that's the correct term). I went to adjust the settings, thinking that it may have been set to Mono, but it was set on Surround. I tested the speakers by placing my finger over one while I listened to another, and the left speaker sounds normal, while the right one sounds fainter.
It's not really a big issue, but is there anything I can do to fix this myself (aside from taking it apart, which I'm definately not doing)? Is there any harm from leaving it like this?
Thanks in advance!
