I have been using samsung level u wireless for 1 year now and its best earphone among my 4 earphones.
Connects easily with the phone.Batterybackup is excellent.
Fits very nicely in the ears. And never fall off easily even during running. Sound quality is excellent.
During calls it didnt showed any problem.
Its comes at rupees 1800-2100. Its expensive but when you use it it will become one of your favourite.
Best for this kinda money.
