Abhishek Singh🥤 Get the Ear (a). Unless you really want wireless charging and want to take advantage of the Advanced EQ. The Ear (a) have better battery life, overall better sound quality, especially out of the box.
I am an Ear (2) owner myself, they work perfectly fine and thus I don’t need new ear buds. However if I would be in the market for some new ones, I’d go with the Ear (a).
