Soundcore's 4th iteration of their liberty line of earbuds specifically designed for noise cancellation. It has pretty good sound & call quality with an advertised 98.5% noise cancellation. It comes in 5 colors (pink, light blue, dark blue, white and black)
Check settings to ensure there aren't any settings labeled "Balance" for people that hear better in one ear than the other. If this is slid more to the left ear or right ear it will cause one to become louder than the other.
Is there anything in the speaker itself?
Take off the rubber ear peice and look at the exposed speaker
