Is a dedicated shower speaker better than a regular portable Bluetooth speaker?

Across the reviewers and Reddit threads we read, the consensus is no. Small portables like the JBL Clip 5, JBL Flip 5, and Sony SRS-XB100 carry the same or better IP ratings than most suction-cup 'shower speakers,' sound dramatically better, and double as travel and outdoor speakers. The dedicated category is dominated by cheap units with weak sound and short lifespans.
