My Buds sound great. I first had the Buds+ and just upgraded to the Buds FE. Have you went into the Good Lock Sound Assistant to modify the settings? The Adapt sound trick helped mine get louder. Once in there scroll down to the bottom and choose Sound quality and effects. Then choose Adapt sound and choose Add personal sound profile. When doing the hearing test answer No to all the Can you hear it frequencies. This will boost all them making the sound louder. I hope this helps you.
