Summary: I bought my 5703F (is that really the best name they could come up with?) about three years ago, and have used it almost entirely for the FM radio. The tuner is acceptable; since it uses the earbud wires as the antenna the reception can be improved (or not) by moving the wires around. Reception is good enough for my purposes, receiving strong local stations just fine. It should not be confused with a proper, sensitive, FM tuner. Sound is great, though.
