Best back-to-school gadgets under AU$100

Google has upgraded its video streamer with (you guessed it) 4K and HDR compatibility. It's great if you prefer to control your video from your phone or tablet.

If you want to give a "cheap but good" wireless travel speaker that's also waterproof, the JBL Clip 2 is the one to get. The fully waterproof speaker floats for a short period before sinking.

The Plantronics BackBeat Fit may not be perfect, but it's one of the best wireless sports headphones available. Light, compact and easy to chuck into a bag when you're not using them.

If you need to type on the go, the Logitech K380 is the best multidevice wireless keyboard we've seen to date. Toggle between three separate devices at the flip of a switch.

It's a little long in the tooth, but if you want to pick up an e-reader for under AU$100, the 6-inch Kobo Glo is the one for you.

We liked the Logitech X100 wireless Bluetooth speaker -- which can play any audio from a smartphone, tablet and many computers -- when it was priced closer to AU$100. But now you can find it for under AU$50.

Now that the Grind is selling for less than AU$100 online, it's easy to recommend this on-ear headphone that surprised us with its refined sound.

The Fuji Instax Mini 8 brings back the fun of old-school instant Polaroid-style photography. The film prints are reasonably priced, too -- which is good, because kids raised on digital love snapping pics.

You'll probably cap out at 1TB of storage in this price range, but for speed and build quality go for the Seagate to keep your files backed up wherever you go.
