One reader will win a Sonos One speaker, which allows users to search, play and switch songs – as well as request information like weather reports – with their voice.

American brand Sonos launched the speaker last year to be compatible with Amazon's virtual assistant Alexa, but plans to link the system up with additional voice services, including Airplay 2, Google Assistant and Apple's Siri-enabled devices.

Currently, users trigger the device by saying "Hi Alexa", followed by a command. For example, they can ask it to play a particular song, which can be streamed from over 80 services, such as Spotify, Apple, or Amazon.

The system can also be controlled directly through the Sonos app.

Designed to fit "just about anywhere" in the home, the speaker comes in either black or white. It is described as medium-sized, measuring 6.4 inches (16.2 centimetres) high and weighing four pounds (1.8 kilograms).

Mesh-like plastic resin wraps around the speaker, forming rounded corners, while the top and bottom are flat to form a sturdy construction. The speakers are also moisture resistant, so that they can be placed in bathrooms and outdoor patios.

A limited-edition set of colourful versions of the speaker, created in collaboration with Danish homeware brand Hay, is set to launch in September 2018.

Sonos opened its first brick-and-mortar store in New York's SoHo in 2016, which is currently home with an installation by artist and illustrator Ralph Steadman.

The space will play host to a panel discussion on Steadman's work on Saturday 19 May 2018, as part of the NYCxDesign festival taking place citywide from 11 to 23 May 2018.

One reader will receive a Sonos One in their choice of black or white. The speaker is available to buy for $199 (£146) from Sonos online.

Competition closes 8 June 2018. One winner will be selected at random and notified by email, and their name will be published at the top of this page.
