Query: Some of the sounds are not very realistic

We have a baby sound spa that has a great ocean wave sound and we were hoping that this Conair device would have a similar quality sound and could play it continuously. Well, the quality of the sounds is not very high. The wave, rain and few other sounds are very muffled and difficult to make out. We're sending it back, very dissapointing.
