This one does have absolutely horrible sound, as if it's treble only, no bass or mids, nothing. The remote has a single power button however and looks like this, even though this isn't an RCA branded remote, this set definitely had a remote that looked nearly identical to this, and said RCA:

In fact the remote number on a universal app on my Android phone IS controlling the TV too.
