Build Quality & Design- Rugged material at top & overall plastic build. It is very light weight & compact in size. It can be easily put in pocket. Overall design is good & build quality is durable.
Battery- It comes with Micro USB cable in the box. For charging need to use 5v 0.5watt charger. It takes 2.5 hr to full charge. In single charge it can play music upto 5hrs. So Battery is decent.
Sound Output- It comes with Dual EQ mode. In normal mode sound output is well balanced not so much loud. I didn't listen any distortion even on Full Volume.
Deep Bass mode produce extra bass but I didn't like it so much because vocals & instruments sound distorted at full volume because of extra bass.
Something more you need to know-
◆Bluetooth Connectivity is good.
◆Mic works good during calls. Call pick & disconnect fuction available by short press of power button.
◆Music can be Play/Pause only.
◆Rubberised material at bottom for better grip.
Overall it is a good & cheapest portable Bluetooth Speaker from the House of Harman. For one or two peron in room you can use it for music & watching movies.
I am satisfied at this price.
Thanks for reading.
