Choosing the correct hearing aid depends on the use determine what you're going to give them. These applications can be listening to music on your player or phone, listen to high-quality recordings in HiFi players, use auditioning critical studies, monitoring use for sound engineers, monitoring for DJs, personal monitoring on stage, and even mastering in recording studios.
You also have the option to choose between intraural design headphones (which are inserted into the ear) or circumaural (covering ears).
The different designs offer different levels of isolation from external noise.
Once you have defined these features will be easier to choose the right hearing aids. "SHURE" for example, offers the full range of headphones for all applications.
