If you want to play some tunes from your phone in your bedroom or kitchen but don't fancy standing around with headphones in, you should get yourself a Bluetooth speaker. The Sony SRS-BTV25 is just such a speaker, offering an impressive sound level from such a small, lightweight body.
It won't replace your dedicated lounge hi-fi, but it's a fine choice for some background music in a more modest room. It's available now for £100 from Amazon.
Design and build quality
Eschewing the usual black square look of many speakers, the BTV25's spherical design is reminiscent of a spaceship from a bad B-movie. It won't appeal to those of you after classic, minimalist design, but will appeal if you like alien motherships noisily invading your home.
With a diameter of 145mm, it's particularly small for a speaker and with a weight of only 500g, it's very light too. Its size means it's easy to find a spot in your living room among those stacks of old magazines and coffee mugs you haven't washed up yet. It also makes it very easy to move to a different room if you fancy some tunes on in the kitchen while you're cooking up something tasty.
Although the plastic is very lightweight, it doesn't feel cheap. We gave it a good few knocks and bumps and were left pretty confident it can survive the odd tumble to the ground. But we don't suggest you throw it around too much, even though it is ball-shaped.
On the top you'll find three buttons: a bass-boost function, one to pair your Bluetooth device and one to select the auxiliary input, as well as volume and power buttons. Around the back you'll find the power socket and a 3.5mm auxiliary input for connecting any devices using the headphone jack rather than Bluetooth. There's a USB socket on the speaker as well, which is only there to provide charging power to a device, not as a connection.
