It’s rare to see a person who has a chance to try both, beside @glucas and yourself here (@banshee), I’m not aware of anyone else, so both your opinions are definitely valued!
I think it boils down to your preference in dealing with speech in noise. The Phonak Sphere I90 will probably give you kind of a bubble where you’ll hear speech inside that bubble really well because other sounds outside of that bubble are eliminated or at least suppressed considerably. But that’s only in a very noisy place. When it’s not noisy enough, the Phonak probably won’t switch to the bubble unless it’s a last resort, so it’s not like you’re stuck with it all the times anyway.
The question is whether you like to be inside the bubble all the times when it’s really noisy or not. If you do, then you have the ideal setup there. And if you don’t want to be in the bubble anymore, you can probably opt out of it via some manual program override. So it’s not like you’re going to be stuck in it.
The Oticon Intent, on the other hand, for sure won’t give you that bubble. And you’ll probably hear a lot more going on with it. Although some people might find it overwhelming, some people might like it this way. They might prefer the awareness of all sounds around them, and they just want help from the hearing aids to get them to understand the speech they want to focus on better, even if they have to work on the listening a little bit harder. They might want to be able to shift focus in a split of a second from one source of speech or sound to another source of speech or sound that may be outside the vicinity of that imaginary bubble. With the Phonak, yeah, they can get in and out of the Sphere mode, but it’s not going to be instant. And you might get tired of having to get in and out of it too often.
So I’d say it really depends on not just the preference, but also the situation as well. If you’re sitting at a table having a conversation with folks at the table itself almost exclusively, then it’s nice to have that bubble to be in because you’re not mobile. But if you’re standing around with a bunch of people and want to be able to hear somebody from across the room calling out to you, or maybe shift your attention around between different conversations going on around you, maybe focus on somebody playing a piano nearby, or listen to something going on on TV for a newsbreak or something, then the bubble wouldn’t work as well as an open soundscape.
I’m wearing the Real 1 right now, so I can’t even pretend to know how the Intent is different or better than the Real, let alone be qualified to say much about the Phone Sphere, except for what I read from users’ experience here on this forum. But I think it boils down to your taste and preference and also even down to the kinds of situations that you find yourself in most often. If you frequent noisy places often and find yourself having a very hard time dealing with table conversations, then it seems like the Phonak Sphere I90 is probably the no-brainer choice for you. But if you’re very active and like having an awareness of your surrounding, and don’t find yourself having to hold conversations in noisy places very often, then perhaps you might like the Oticon Intent better. You just can’t go wrong with either. It’s more like which one you find is more suitable for yourself and your lifestyle.
