All systems go

THE LATEST gizmo from Thai manufacturer Nicon Thai Sales and Service, the Sherman S20 is a new Bluetooth speaker in a compact and portable size boasting five LED colours that flash in time with the beat.
The S20 has a footprint of only 12x20x12 cm and weighs just kilogram. A carrying handle makes it easy to tote around.
It has output power of 2x5 watts and the speaker system has a frequency response of 50Hz to 20kHz.
It comes with a 4,000 mAh rechargeable battery that can play music for three to four hours and in case of emergency, the portable speaker can recharge your smartphone, using its USB port.

The S20 supports Bluetooth 2.1 for streaming music from a smartphone or tablet computer. It comes with a play/pause button and volume control buttons for music on your phone or tablet. Moreover, the S20 has a built-in microphone so you can use it a speaker phone system.
It can also play music files stored on a USB drive or a micro SD card, using the same control buttons.
The S20 uses a voice interface to interact with you. For example, it will tell you that it is ready for Bluetooth connection when you press and hold the power button for about five seconds.
I tested it by streaming music from my Huawei Mate 8 smartphone and enjoyed the music quality of the speaker. The S20 has good music clarity. Although the bass was not powerful and deep, there was still enough of it to allow you to enjoy the songs.
I mostly played rock and found the music quality okay though not brilliant. For example, I enjoyed the lead solo on “Still Got the Blues” by Gary Moore.
The S20 also played MP3 files on a USB drive without problems or glitches and with good music quality.
Sherman S20 retails for Bt1,990 and is on sale at Tesco Lotus, Big C, Macro, Power Buy, Home Pro and Power Mall.
