There are very few reviews on HT for power aids probably for two reasons. Power aids are not sold in mass volume since most folks with a hearing loss don’t have a severe/profound loss. The other reason could be poor HA aid performance in the power or (UP) group, though overall performance can vary greatly from one brand to another. Anyway with my challenging hearing loss I went with the ENZO Q 9 - 17 channel. I initially went with hard acrylic custom mold with vent, which is what I’ve worn for for many, many years. Unfortunately during initial aid testing my Audi claimed the vent was preventing the Enzo Q from reaching its true potential. Or shall we say not allowing my Audi to adjust the aid up to full sound/power levels. I’ve used power aids in the past with vented molds and have never had any feed back problems what so ever. But in the case of the Enzo Q - my Audi gave me the impression the aid will only function properly when paired with a silicone ear mold with no vent. To which I replied “well if that’s the case why wouldn’t Resound mention the “no vent restriction” in HA literature”?
So after another ten day wait I got replacement silicone molds, keeping my fingers crossed I wouldn’t feel or sense any signs of occlusion when I tried new molds. When inserted the molds were very snug, while the aid itself was on the large size - which didn’t bother me a bit. 675 battery aids are going to be large to begin with but power is my friend. We did some basic tests and it appears I was in the upper limits of the aid range. General communication back and forth in Audi office seemed fine but even with clear mask and distance factor you’re not going to get the ideal environment to test aids as in the past.
From there things seem to go down hill very quickly. The next day while wearing two new aids I noticed around mid-day might right ear aching. Come evening right ear was very uncomfortable more so when removing ear mold. One of the Resound negatives pointed out by Dr. Cliff was ill fitting ear molds - and I certainly can verify that’s true. The left side mold was basically OK but still really snug. In any case my Audi said to wait until I see her in two weeks to make new mold, so I kept testing aids off and on. On day two I noticed when I walked outside the right aid started softly buzzing on and off. It also happened in car when I was driving but was quiet in home for some reason. When I turned volume level down a notch or two the buzzing sound got softer but was still there. I also made sure tubing was properly attached, which is a little different with the Enzo’s. In the old days when I had plastic tubing the tube was alway pre glued or cemented to the ear mold. With the Enzo Q the tube is removable, so its easy to pull apart when removing from your ear. If that happens you just push tube back on aid body insert. In any case I basically had some level of aid distortion which along with ill fitting mold - made a nice two punch combo.
I had no signs of occlusion effect (with no vent) until my wife and drove over a very long and high bridge on day three. At the height of the bridge my right ear drum popped but of course ear pressure/air had no where to escape to. Then two hours later when I returned home home, I took new aids out only to feel my right ear drum start to constantly pop on and off for the next several minutes. Eventually the issue went away.
Enzo - performance. The aids do have power and lets just say I heard as well or slightly better (outside) with the Enzo Q 9 versus my old Widex power aids. Inside though I noticed my TV volume setting was about the same with new aids and I was hearing my wife about the same level as when I wore my older Widex aids. Resound probably had a touch more power but I really can’t say my speech discretion was any better. Sounds in general sounded norma/natural inside and outside again very comparable with my old aids. I was not able to properly test the Resound aids in background noise but I also think my Audi might not of set up “noise programs” in proper settings. Reprogramming for background noise aways takes several Audi visits, in an attempt to get thing just right. If an aid ever really works right in background noise.
The Enzo Q have a extremely difficult battery door to open, if you want to turn off your aids while they are still on your ears. My Audi either couldn’t or didn’t try to program a “mute” feature on my aid control. So with a sore ear it was not fun having to turns aids on and off by removing and then re-enserting. There were also 9 individual sounding dings in each ear when HA is activated. So with two aids - that’s 18 ding, ding, ding, every time you turn aids on. Yes it will wake you up.
I did find the streaming to be very good with my iPhone and I’d say that was one of the aids strong points. Obviously it takes time to get comfortable to a new aids but due to ill fitting molds along with right aid distortion my Audi (and I to some extent) thought the Resounds would not work out. You might add the ear pressure issue which could kick in when taking an elevator up a very high building, driving in mountains, plane flights, etc. At those times I could always take aid out - but I most likely do need a small pressure vent to relieve built up ear pressure.
I should also mention that a previous audiologist rated the Enzo Q over the Oticon Xceed as did my current Audi - so I will not be testing the Oticon aid.
