I was looking for inexpensive portable Bluetooth speakers and am so encountered the ARCTIC S111 BT. What has led me to buy were the separate boxes and thus the possible stereo sound. The speakers are nice and compact and safe transport with the included case. Ideal for use on the lake or the cozy barbecue. The condition of the speakers is easy: Switch on the device, activate Bluetooth, pair devices and away you go. Using the buttons on the back of the system, I can easily the media player of my S3 control with features such as play / pause and next / previous. The sound made me quite surprised for this mini-system. There is simply nothing to complain about and thanks to the built-in battery is a long playback time of min. 10 hours is possible. Despite the low price of this product is anything but cheap. The design and the processing and the material of the housing are modern and valuable aspect as the pushbuttons on the back.
