10 Smartphone Gadgets you may not believe exist.

Tiny gadget that turns any object into a speaker, and he found it hugely fun and surprisingly capable.

The best thermal camera you can get for a phone, mostly useful for trades like plumbing but fun for exploring too.

A flexible, sticky phone stand that seems odd at first but he found genuinely clever and very versatile.

A tall ring light and tripod kit with Bluetooth remote that gives fairly professional selfie results after some assembly.

Unusual headphones with a very different design, magnetic case, no buttons and a hybrid in-ear and over-ear fit with powerful bass.

A cheap-looking case that redirects the flash as a notification light; he found it interesting but wouldn't recommend buying it.

An expensive water-resistant suitcase whose interior acts as the sound chamber for a built-in Bluetooth speaker.

A cheap, cheerful and surprisingly bright disco light that does the job if you want a small rave.

A foldable camera that switches between 180 degree VR and 360 degree capture, with good stabilisation.

A single-colour smart lamp controllable by app or by twisting the top, with scale features he calls useless but cool.

An affordable rig for mounting mics and lights and holding the phone steadier.

A better version of a PopSocket that turns into a ring for use as a stand, car vent mount or grip.

A slightly pricey but high quality, washable silicone phone stand with three angles.

Touch-controlled square light panels that are bright, vibrant and highly customisable.

A colourful ring that protects phone cameras on flat surfaces and in pockets.
