Motorola has some phones with headphones jack (and microSD) that I think are even thinner, at least it feels that way compared to my Xperia. They're significantly cheaper too.
I will say I increasingly reach for my Sennheiser earbuds over the wired headphones/earphones for convenience. But the audio quality of Bluetooth is just awful compared with wired audio.
