Query: Only option for the iPod Shuffle

After a long search this is the only product I found that would work wih the iPod Shuffle. It is very simple to use, but the sound quality isn't all that great. The volume is low and there is interference with all 3 station options for transmission. I would buy this only if you owned an iPod Shuffle because it's your only option.
