Spigen SGP GLAS.t Nano Slim Screen Protector (£30)
The Galaxy S5 may be newly ruggedised, with water and dust resistance carried over from the Galaxy S4 Active – but bumps and scrapes are still a daily risk.
While the phone's replaceable back means that you don't have to worry too much about that side of things, the screen is a likely candidate for scratches. This tempered glass screen protector is just 0.23mm thick, and packs the same oleophobic coating used on smartphone screens to prevent smudges. And even if you do smash it, an anti-shatter film will prevent it breaking into dangerous fragments.

Jawbone Era (£65)
Bluetooth headsets may have fallen out of favour, but they're still very useful gadgets. And in recent years, they've become much more refined than the clunky Borg-like appendages of old. The Jawbone Era is a case in point; it's small, stylish and packed with tech, including noise and wind cancelling, an accelerometer and tap to answer function.

Samsung Body Scale (£80)
Samsung's pushing its S Health system heavily with the Galaxy S5, using its battery of sensors to track your fitness. If you want to take things a step further, this Bluetooth-equipped body scale will send your weight measurements straight to the S Health app, saving you the bother of typing them in.
Ultimate Ears UE Boom (£170)
Bluetooth speakers are ten a penny – so why drop £170 on one? Well, for one thing this brightly coloured tube of tunes pumps out "weighty and involving sound" (according to our chums at What Hi-Fi) in a 360-degree radius. And you can link two UE Booms together for stereo sound, using the handy Android app. Plus it's water resistant – just like your Galaxy S5.
Samsung MHL 2.0 HDTV adapter (£25)
This handy gadget lets you plug your phone into an HDMI-equipped TV – which, since the Galaxy S5 outputs 1080p HD, means that games and videos will look just as good on the big screen as they do on the small one. Perfect if you want to watch Netflix or iPlayer on a hotel room telly.
