I have been using this product for around 5-6months . Till now I haven’t faced any connectivity or any such kind of issues. Its value for money. The battery backup is superb, one of the best right now in the market. Like once charged to 100% it can be easily used for 3-3.5hrs continuesly. Sound quality is also amazing , bass is also quite impressive. The best part of this product is that it doesn’t easily fall off while running , so you can without any fear use this while jogging. Design looks little bulky but the weight is not that much. So overall I would give this product 9 out of 10.
