If you've been sweltering inside like us then it's time to head outside to a shady spot and relax with some decent tunes. Here are 5 of our favourite Bluetooth speakers which perfectly pair up with a smartphone for some music 'al fresco.'

TDK Trek Flex (around £70)

Boasting a resistancy to water, dust and knocks and bumps, these speakers have been designed in a cylinder shape and offer 360 degree sound and an impressive bass. There's a button on the side so you can change your tracks on the speakers themselves and they can be positioned horizontally or vertically to fit in with the space available and type of terrain.

 

UE Mini Boom (approx £55)

Weighing 300 grams and with a width of only 11cms, they may be mini in stature but they certainly don't lack power with a max sound output of 86 decibels which is clear and crisp. Featuring rechargeable batteries which can power around 10 hours of music playback, they are compatible with smartphones and any Bluetooth enabled device.

 

Bose Soundlink Colour (£120)

Bose_Soundlink_ColourThe big name doesn't necessarily mean a big price tag. Superb value speakers from sound specialists Bose and available in a choice of some fantastic colour options. They are fairly light at 500 grams and will last around 8 hours between charges. With beautiful sound quality and great clarity, they can also be used with devices which don't feature Bluetooth as there's a 3.5mm jack on the back.

 

Sony Ultra Portable Wireless Speaker (around £42)
