Another possible interesting one-up that MFi HA’s might have over the Lumity with only BT 4.2 is the following:
The Apple Watch Series 8 is a BT 5.3 device and you can get it with LTE cellular connectivity. So, I’ve been wondering when Apple pulls the covers off BT LE Audio whether an Apple Watch 8 GPS+Cellular could be paired directly to a BT 5.3 HA via the LC3 codec, etc. That might allow both handsfree phone calls and streaming from the watch instead of the iPhone.
I have an Apple Watch Series 6 and it only does classic BT so I have to use the Phone Clip+ if I want to pair with my ReSound Quattros. So classic BT isn’t very nice on watch battery life and I think with that arrangement any phone calls still depends on being near my iPhone since my Series 6 is not a cellular device.
Right now, if I want to listen to a podcast while out walking, I have to carry my iPhone with me and especially in the winter wearing heavy clothing and gloves, I’m always worried about dropping the phone on asphalt paving. There are many other dusty, dirty, or wet situations where I don’t want to be carrying my phone with me but it’s easy to wear a pair of sound muffs over my HA’s to protect them from the environment. I have the Ultra model of the Series 8 so my watch is pretty impervious to the elements, too.
Perhaps if a Series 8 Apple Watch could act as a BT LE Audio host, Apple would have made some announcement in releasing the new models. But then they’ve been mum overall on BT LE Audio - maybe the technology is so new in its availability that it’s utility is meaningless to most people right now.
Still, it’s a tantalizing thought that at some point in the future, a Series 8 cellular watch might stand in for an iPhone used with MFi HA’s. The Ultra has a battery 2x bigger than the regular Series 8 watch so one should get double the run time with whatever you connect it to (Apple rates the Ultra as having a 36-hour battery runtime).
Edit_Update: BTW, even without being paired directly to my HA’s, the Ultra is a great cellular device. I switched to Spectrum Mobile as it’s a lot cheaper than AT&T or Verizon to have a plan that supports a cellular Apple Watch. Spectrum Mobile is an MVNO (Mobile Virtual Network Operator). You can only subscribe if you’re a Spectrum Internet cable customer. They’re counting on you doing most of your usage via Wi-Fi at home or connected to Spectrum Wi-Fi hotspots. But when you’re away from home and not near a hotspot, you get to be on Verizon’s 5G cellular network (the Ultra watch is only an LTE cellular device). So, all of the previous is just to give context. With the Apple Watch 6, the watch speaker is small and not very loud. On the Ultra, there are three beam-forming microphones, and the speaker(s) is/are a lot bigger and louder. Whether using cellular or Wi-Fi calling, the wife comes through loud and clear just listening to the watch held near my HA’s (Dick Tracy style) with the speaker volume turned up. The wife says in return that my voice comes across crystal-clear. I don’t think the regular Series 8 watch has the enhanced microphone or speaker system. But while enjoying the easy-to-understand phone calls with the Ultra watch, I got to thinking how much better it would be if it could serve as a handsfree device for a future set of HA’s. Maybe that possibility is still at least a year or two down the road?
Further note: Spectrum (a Charter subsidiary) is relatively screwed up in that an unlocked BYOD Apple cellular watch requires special technical support to be activated on their network as opposed to a device from them already locked to their network. It took me a week to get my BYOD watch activated. The Internet is full of complaints about this. But I’m on a $14/Gb plan + $10/mo for watch = $24/mo. $38 if I consume > 1 Gb & <= 2.0 Gb/mo, no taxes or surcharges. So, far 2 weeks going, I’ve used 0.00 Gb outside my house even having cellular data on when I go for long walks (I don’t get many e-mails or texts with pictures, etc). Being an old geezer, my principal reason for a cellular watch is to be able to call 911 even if my phone isn’t anywhere near me, wherever I am and whatever I’m doing. And it’s nice to have a watch as an HA user where I can hear clearly and be heard clearly, supposedly even if the wind is blowing, because of the beam-forming mics.
