Personally, I have been using the Boult Z40 Pro Bluetooth headset for a few months. The company claims a 100-hour battery life, but it actually delivers decent battery life. You can get 120 minutes of playback on a 10-minute charge. The scratchproof rubber grip case is very useful and likely to be used. The only thing I found bad was the difficulty in claiming the warranty. Since Boult does not have many service centers, I had to courier the product pack to Delhi. It took about 20 days to get it couriered, serviced and returned. It was a waste of time and money.
