SOUND is always personal and subjective. Different people have different favor and auditory sense. Some prefer high, some enjoy mid or bass. Moreover, the output sound also differs from different audio files. We always try to provide as rich as possible sound for you. Lack of Bass ? Please try to adjust the ear tips, or change to smaller ear tips and push them a little deeper inside your ears to see if you could get better effect. Volume Not Loud Enough ? Please adjust it through your device. There is no volume control button on the earbuds as for the small size and compact design. The manufacturer always make standard volume section to bring you beautiful sound as well as protect your hearing. No Cover for the Case ?
