Customer feedback highlights the sound options, dimmable night light, compact size, and alarm functions as positives. Sound quality is mixed, with some customers appreciating the white noise and others wanting greater volume. For buyers using the H04 as a bedside sleep aid, that difference may matter more than the listed 5W speaker output, which does not establish how loud it will sound in a particular room.
