I have been using the MI Bluetooth basic headset for almost 7 months as of now and I must say that the product is really nice and easy to use. I purchased it from mi.com at price of about 799INR with 100INR discount.The package contents-1. Bluetooth headset 2.charging cable 3.ear tips ( S, M, L) 4. User manual.The product comes in two colours Black and white. It is very light weight , weighs 6.5gm only.it has Bluetooth 4.1 with a range of 10 metres and can be connected upto two devices at a time. It gives a talk time of 3 hours and can be charged with a duration of 2 hours. There are three total buttons on the headset , one is for taking and ending the calls and the two other are for the volume up and down.Now let me tell you about the performance of the headset itself , in my usage I didn’t find any kind of trouble with the device and the quality of the speaker and the mic is also very nice.It is compatible with any android , iOS devices and on bar phones also. So no need to worry about that.Thanks
