I got my Infinio Sphere I90s today from Direct Hearing, and they’ve been great so far. I haven’t tested Spheric noise reduction yet, but everything else seems super. Unlike @JordanK, I have not noticed any problem with M receivers, perhaps because my hearing loss is not as severe as his across the frequency spectrum and I have much more headroom over most of that span. I have typical age-related (noise exposure-related?) ski slope high-frequency loss. The sound through my M receivers is great, with no warble or distortion that my non-audiophile ears can detect.
Speech Enhancer works very well for me. My wife’s soft-spoken voice comes in loud and clear. As to how it compares to the Lumitys, I haven’t had my ears cleaned as I did just before my Lumity trial. I’m having trouble pushing the dome-equipped receivers into my ears without caking them with wax. That’s part of the reason I like molds, it’s much easier to avoid that! So, I might not be getting my wife’s voice coming through as clearly as it might for not yet having the molds I plan to get.
@jeffpa complained of hearing a hissing sound from the Spheres in certain circumstances. Today, sitting in my kitchen, I heard a very distinct hissing sound, and my reaction was, Oh, No! It turned out, though, that I was hearing the refrigerant of our refrigerator/freezer percolating through the coils after a lengthy cooling run of the frig compressor. I’ve never heard that with my ReSound Omnias, Quattros, or the Phonak Lumitys I trialed. Might not be as cool as hearing birds chirp far away in trees, but I was very impressed.
I had trouble getting streaming to work until I deleted my ReSound Omnias from my iPhone Hearing Devices settings. Even though the Spheres use classic BT and the Omnias use Apple’s proprietary MFi BT-like LE streaming, MFI devices must have a lock on streaming as long as one is paired with your iPhone. Thanks to anyone for letting me know if there’s a way to have a MFi HA and a Phonak HA both set up to use with an iPhone simultaneously.
The other delight was finding out how well hands-free calling works. And that’s another area where I could use some help. It seems like as long as I’m connected to my iPhone, the Sphere mics take over the mic input to the iPhone. With the Omnias, there was a setting, IIRC, to switch between HA mic input and iPhone mic input. While the Sphere mic input to the phone is good - my wife says it’s clear on a phone call - iPhone microphone input is exceptional. I haven’t found a way to switch between the two inputs and still have the Spheres connected to my iPhone.
If I pair my Spheres with my computer, on my computer, I can select the source of microphone input. The Spheres will provide acceptable voice dictation input for Dragon Naturally Speaking 16 Professional but not the quality of a Logitech Blue Yeti X Professional Condenser mic sitting right on the desk in front of my mouth.
Thanks to @JordanK and everyone else for their Sphere reviews. The excellent reviews prompted me to squander the money for the Spheres, and I’m very glad I did so far.
