A few years on, and I tried the Hooke Verse binaural device again. Maybe there's no much point in discussing it now as the company seems to have gone out of business, but maybe there's a few of them floating around on eBay or whatever.
Anyway, I revisited them as I have fairly recently been putting "Comply" memory foam tips on my Sennheiser and Roland binaural mics to very good effect, but didn't use them on the Hooke device because it needs tips with rather small central holes to attach to the actual earbuds. In trying to discover the exact size required, I noticed an old advert for the Hooke Verse which mentioned that foam tips were included in the package, and having eventually found them, they actually work pretty well and keep the Hooke Verse snugly in my ears for extended periods. Then when experimenting with different Android devices I found that my 'daily driver' phone which uses BT to link to two watches (at once, yes, really) exhibited poor connectivity to the Hooke Verse, but another one which had no active BT connections ran fine for half an hour. So my chief problems seem fixed, finally.
So, maybe I'll start to actually use the Hooke Verse at long last - the battery seems ok - for instance, it would make a good system alongside my Insta360 Go 2 video camera which has poor audio built in (and no mic socket). The tiny Go 2 can be worn below a face mask (yes, really, again) and with the Hooke Verse worn in my ears, that would be a pretty minimal wearable video/audio system. Please try to contain your excitement pending the upload of a YouTube video of this in the next few days...
