I’ve used activevents since around April 2022 with my audeo p90-r HAs. It has a mechanical valve which is electrically operated that opens or closes a vent in your ear piece. When you aren’t streaming or in a very noisy situation, this prevents unwanted sound from coming in. When you aren’t in one of those situation, it opens to allow the natural low frequencies in, preventing occlusion.
It doesn’t come with audeo hearing aids, but it is available. The end of the receiver is quite different. You can use rubbery silicone “universal slim-tips” (which come in a variety of sizes) or titanium custom slimtips. I don’t think there are other tip choices.
(But what do I know? Not much. Mostly ueless information.) Usually patients start with the universal slim-tips until they know they want to use the activevents permanently, then they have the option to get the titanium tips. I love my titanium tips and the activevents.
They (the receivers) don’t last as long as conventional receivers. I think wax gums up the mechanical part. I don’t think the wax traps are effective at all. They (the receivers) are estimated to last 6 months. I get a bit longer in one ear, and not quite as much in the other.
There is an audible click noise when the valve switches position. Some don’t like that sound. I not only am accustomed to it, but it signals to me that there has been a change (typically a call coming in, before I hear any ring) and I don’t mind it at all.
It is only available in the “M” level of receiver power. There is a chart with fitting ranges your audiologist can show you, or you can search here for where it has been posted multiple times.
I hope this helps!
