Although every product of Mi is great but this your phones I am really telling you are the best of all of them as they are very good bluetooth earphone in a very low budget. I think it is the best available bluetooth earphone in this budget of 1499 rupees. The earphones perfectly fit.when I bought them I thought there why equality is not good and they are not durable but they are completely prove me wrong. Tthey good for workout as well as for jogging.the earphone are highly durable and not required too much maintenance. The company provides this earphone in two colours blue and white. Moreover it comes with IP 5x splash proof. So you not have to worry about your sweat during workout. I am not recommend you to wear it during swimming and while taking bath. The battery of this earphone as long lasting all the company claim for 8 hour battery life but I get 5 hour of non stop playing music which is more than enough. And it only takes two to three hours to get charged fully. The sound quality as well as the vocals of the earphone is very good the base is not too much loud and not too much low it is perfectly fine and well tuned. if you have any question regarding to this earphone you can comment down below I personally use this earphone so I can better clear your doubts.
