Have had an 83i roberts radio for years. Have used it every summer outside in the gazebo when having barbecues. What a great entertainment system. Not only have I had just about every radio station known to man at my disposal, I could also play every one of my CD's that are stored on my hard drive and connected to my modem . BUT then I bought an S1 speaker and a R100 and they are fantastic. An even better sound and the ability to connect/sync the 2 together. Well good for connecting the gazebo to the barbecue area. So good in fact that I have just bought anotherS1. I am very, very pleased with the sound quality for such a small footprint and it seems so is every body else. Thoroughly recommended.

Ticks all the boxes, great sound quality & volume

I wanted a multiroom system compatible with the UNDOK app where the speakers were small but powerful. The Roberts S1 ticks all the boxes. Using them lives up to all expectations. Great connectivity options. No DAB but with internet radio and bluetooth you don't need it. I'd like a few more for the rest of the house!

Small Box with a Big Punch

I was torn between Sonos, Bose and Roberts solo speaker. I own Bose headphones and love them, a friend has a Sonos system and he loves that but I checked out all of these at John Lewis and the Roberts edged it for me on style, sound and ease of use. Simply plug it in, download the UNLOK app and away you go, I even connected it using an ethernet cable to my router and grabbed all DAB stations, it was so simple! I love this speaker and I would highly recommend it to anyone who love music and an easy setup.
