All settings can be made with the hearing amplifier comfortably in your ear.
There are nine different levels of voice amplification and each level can access any 1 of 3 environmental modes.  Each mode has a different audio frequency response to accommodate the varying degrees of ambient noise situations you may find yourself exposed to.  This in essence gives you 27 different voice amplification programs to choose from.  This is why having the ability to access all 27 programs without removing the hearing amplifier from your ear is so vital.<br /><br />Choosing the correct dome is extremely important, this is what prevents whistling, gives you a comfortable fit and holds the hearing amplifier securely in your ear.  Additionally, a fully charged battery lasts from early in the morning to late in the evening, an accommodating feature.
