I'm torn between my Media Player or my Headphones as the best recent gadget purchase.

.....
I have a Dune Smart D1 and it really does get a load of use. After ripping all my DVD's and Blu's, I'm watching so many more films now I have instant access to it all, from the "Video Wall"
Headphones... I picked up a set of Sennheiser PXC 310 BT a couple of months back. These baby's have bluetooth, APT-X codec and Noise Isolation. The sound quality blew me away. £200 well spent as I use them about 6 hours a day
