Query: I have an iPhone. I am stupid for buying this

I accidentally bought this because I thought it said "Compatible" with iPhone/ipod but when I read it now it obviously says it's incompatible with those devices. While it's my fault I bought it why do they even mention that it's not compatible? I mean. My iPhone charging cable doesn't support Sony Walkman but there was no tag on the box that said "Not compatible with Sony Walkman" on it. I think they put that on there because they knew that people would see it more searching the term iPhone or iPod and the giant label on the box that says don't open it if you plan to return it and the iPhone warning on a huge label indicates that I'm not the only dolt to make this mistake.I am giving them 1 star because they are purposely trying to get hits on this product using keywords. Amazon, fix this listing.
