Resound Enzo Q - Disappointed

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.

My Hearing Aid Specialist fitted my Resounds with molds with vents (1.3). I was a little skeptical since I always used a power dome for right ear. I am very satisfied. I have very little if any feedback. I always felt like my right ear was plugged up but now do not. They are hard shell molds. He explained soft molds are like pencil erasers. eventually rubbing the inside of the ear and also wearing out. I cannot imagine the feeling of my ears popping and not being able to relieve the pressure. Hope this helps and hope all is well. Be safe.

@spectrumplay Are you sure the molds you have came from Rssound? The nice thing about a BTE is the molds can be from anywhere. My left mold for my Resound aid, if it ever comes, is from Emtech. Silicone molds will always be pressure fit on the tube according to what I have read. Your molds were glued previously because they weren’t silicone. You can get a little metal tube lock though, you should ask about that.

None of what you wrote sounds like any kind of problem with the aids themselves so I don’t think it’s fair to give them a bad review. With the power you clearly need, any vent will cause feedback because the sound escapes out the vent. This in turn limits the gain since the hearing aid is fighting feedback while trying to provide output.

One nice thing about a cochlear implant is feedback is impossible because there’s no sound, just electricity. Unless you have electroacoustic setup, but I won’t.

Not exactly sure where molds came from. I do know that aids showed up on one date and then molds showed up a different date. If I was a HA manufacturer I’d sure want to produce my own molds, since if someone else makes molds and screws up - the aid manufacturer might just lose a sale.

Agree the mold comfort issue and the ear pressure issue were not aid related. HA distortion can be many things (in my case buzzing on and off) but if it shows up on day two - just think how aid might perform after 3 months, after 6 months, etc.

I bet the “far” majority of HA users with custom ear molds have a pressure vent. Obviously in the case of power hearing aids a mold vent could be a blessing or a problem - but I think all power aid manufactures need to come out and specify what mold type/material can be used and if a vented mold is allowed or not allowed. Why play the guessing game when the aid manufacturers know what works and what doesn’t.

The more reviews we get on power aids the better but basically I’ve read zero (in depth) reviews on the Oticon Xceed and I believe I did the first review on the Enzo Q. That’s with the Xceed being on market fourteen months and the Resound Enzo Q launched back in February. Lack of reviews tells me the (severe) hearing impaired are either not buying these aids or if purchased, users for what ever reason don’t care to share performance results.

This has absolutely nothing to do with the manufacturer and everything to do with the hearing loss configuration of the patient. It’s up to the audiologist to balance the wants of the patient (I’m used to X, give me X) with the needs of their prescription. A BTE hearing aid can fit a variety of losses (not obviously true of a superpower aid but they do still have a range of audiograms they can be used with) so a manufacturer can’t say these can only be used with a full shell deep canal silicone unvented earmold. That wouldn’t make any sense.
