I’ve wondered about this, too. I don’t hear anything at night, including alarms. Have relied on husband and dog to wake me if necessary. But I felt very insecure recently when husband was traveling, and we are currently dogless.
No one has mentioned feedback. That would be an issue for my Oticon Intents pressed against a pillow. And of course the charging issue for rechargeables.
