The functions of this BT-118 has been highly integrated: hands-free answering phones, enquiry line, TF card player AUX input, nightlights indication, touch control which makes it more practical fashion. I just love the design this speaker has. I t is so cool and the colors really make it pop. This is a quality speaker, as the music plays the lights flash to the beat. It sounds really clear and is loud. This is a speaker you can take anywhere and use it without a power outlet. Because this Bluetooth speakers uses rechargeable batteries. It has a smooth body, nice and round, and light weight. You can charger this anywhere just plug the USB cable into any port and let it charge. The larger speakers, especially those intended for home theater or PC need a dedicated power supply to run, even though you can connect to your devices wireless. Size is everything. When it comes to traveling and location. Beyond an auxiliary input, you can connect your smartphone or tablet with a wire, or you can Bluetooth by transmitting your music, books to your speaker. This speaker is well worth the price. I would say you can give this as a gift but I am keeping this for myself. I got a great discount for this speaker.
