Sony walkman S544 S545 Series TPU Silicone Pink Case + Screen Protector + Car Charger for Sony walkman + Wristband
I am unsure how the product works since Bestpricecenter sent me wrong item.  In the product discription it stated that it worked on Sony Walkman S545.  Unfourtunatly when item arrived it had a different connection than my walkman.  I sent the item back and was given a refund although I did have to pay to ship it back which was almost as much as item cost!!!
