Question: Is this compatible with a Samsung Galaxy S 4?
Document: The description of this item stated that it is compatible with the iphone 4, but it is only compatible if you buy a cord.
It was not compatible with my Apple IPod, the connection was not the same, would of had to buy an adapter........
Works great ! Nice for my bathroom. Compatible with iPhone 5 and the iPhone 5s. Not bad price either. Buy it
While this item seemed ideal for my office, it basically is compatible w/ every iPod and iPhone except for the iPod I own. Wish I would have known that. Very, very disappointing.
I was very excited to buy this newer version of my Sony AM/FM Dual Alarm Clock with iPod functionality and remote control. However, this is not compatible with older iPods/iPhones.
A video review and the reviews here on Amazon were mostly positive. There were mixed reviews about the dock being compatible with cases so I decided to order it. I have a Speck FabShell Burton case for my iPhone 5 and it will not work with this dock so I will be returning this product.My case:  [...]
This is the main reason for giving this item 4 stars.Otherwise, this item works well and overall, I'm content with it...for now.
Okay, let's get this out of the way... When you first plug in your phone, it displays a message on your phone, explaining there is an app in the App Store that you can download to enhance your experience and add some functionality. This message is NOT a nag/incompatibility message. It never returns after you acknowledge it. This radio is iPhone 5/Lightning compatible, full-stop.
I have had the same clock radio since the early 80's. Not even kidding. I am 31 and I think my clock radio is too. It's still going by the way, but I figured it was time to update with something compatible w/my new iPhone 5. GREAT DECISION! I agonized over which to get and looked on ebay, on other sites.
I don't have this radio speaker dock. This is just a tip with the lightning connectors. If you are having problems with a thick case, as long as it is a case that only covers the back and leave the bottom where the lightning jack and speakers is exposed like this one:eForCity Snap  Compatible iPhone Purpleyou would be fine. Just have the phone face the back of the dock rather than the front. Remember that the lightning connector works in either direction.
Answer: No. Its for an iPhone 5. Read the product description.
