I’ve never worn any other HA’s than my Quattro’s so I wouldn’t want to influence your choice too much and think if you have the opportunity to make comparisons, your own feelings and findings are your best guide.
I’m very happy with my Quattro’s but if you’ve read my posts widely, you’ll find that there are some things that I’ve been unhappy with. The sound quality streaming through the PhoneClip+, the Multi Mic, and the TV Streamer 2 is really superb, IMHO, especially wearing occlusive earmolds that trap the bass and lead to a deeper sound there. By comparison, I sometimes don’t think the quality of sound heard through the external mics is quite as good-still very good almost all the time but not as “knock-your-socks-off” as the streaming sound for me. Other folks have not liked the streaming sound as much, says it lacks bass, etc., but perhaps some of these differences are a, “Do you like Beats audio?!” type of preference difference. Perhaps my perceived difference with external mics relative to streaming is just the way HA’s work relative to background noise or that my external mics are half-clogged all the time due to me being psoriatic, etc.
The other perceived difference is the delay in changing sound environments. If one goes from a loud, noisy environment to a soft environment with soft speech, there can be as much as a 5-second delay before the Quattro’s change sound settings. Transitions between more similar environments are more rapid, down to a second or less. I gather from reading Marvel posts that few Marvel users detect a transition period. When I think about it, perhaps it is good to have a delay to average out what sort of environment you’re really in. If every second that there were a change in noise level or speech being present or absent and the environment constantly yo-yoed back and forth, that could get annoying fast. Works the same way going the other way, too. If I turn on a stovetop fan or a bathroom fan, it takes about 5 seconds in a quiet environment suddenly made noisy for full noise suppression to decide to kick in.
I do especially like the Quattro’s for the Smart 3D app and the quality of the accessories. And the fact that, although the accessories are expensive, they are nowhere near the cost of Phonak’s Roger devices, especially if you get them through Costco. I do wish the Multi Mic in the omnidirectional mode had better noise suppression and/or like the Roger Select, I wish that one had more control over the direction of microphone pickup when the device is lying flat on a table. The TV Streamer 2 has made a night-and-day difference in understanding TV dialog, especially in movies.
I think ReSound could still stand to improve the quality of its BT connectivity and have a real battery health indicator for the long-term state of the Li-ion batteries. If I had it to do over, I might opt for the disposable battery version of the Quattro’s since I don’t think the Li-ion ones will last as long as they might if I wear them outside for long periods in Texas summer heat of 100 to 110 deg F. But other than summer heat, I’m very happy with the Li-ion rechargeables. It may be true of all HA OEM’s but the “system” basically requires you to rely on your HCP for HA support information. I wish ReSound and all other HA OEM’s had a stronger, direct-to-the-company support system in terms of getting technical questions answered, providing feature suggestions, etc… But then even with a Samsung smartphone, I find it hard to give feedback to Samsung or get expert technical advice on my smartphone.
I also got the Quattro’s looking forward to ASHA connectivity but with LE Audio coming along (BT 5.2), etc., and liking very expensive high-end smartphones, I decided it wasn’t worth upgrading my Galaxy Note 8 just to get ASHA connectivity right now and was disappointed that Google didn’t get it out in an earlier version of Android. And I have wistfully thought I might enjoy my HA’s even more if I were an iPhone user but for starters I don’t like Apple’s inability to configure one’s phone screens with apps and widgets arranged in a very customized user interface.
The other thing that I enjoy with the Quattro’s but you won’t with a Costco version of ReSound is the DIY accessibility if I want to use it. I’m happy with default settings (autofit), having switched my profile to Experienced User-Nonlinear and to the NAL-NL2 fitting algorithm after my own experimentation. The quality and design of Smart Fit software impresses me and although I’d probably rely on my audi for any advanced settings changes, the opportunity, thanks to help obtained here, to learn about the settings and again, thanks to suggestions made here, to take a number of Audiology Online ReSound courses help me understand hearing and my HA’s better.
So, yes, I love my Quattro’s, I think the money was well-spent but I can see there’s still room for improvement, faster processors, more heat-resistant, longer-lived batteries, etc. And I’m not sure the Preza is 100% the Quattro’s without just a few features. Some of the HCP providers who frequent the forum or maybe the folks at Costco would be better qualified to address that question. Sorry if I have missed posts on the forum that have already settled that consideration.
