I've got moderate to severe SSHL and use an Oticon intent 1 miniRite. For my use it's been very good - long last battery, relatively robust. It also has excellent bluetooth connectivity, so I often use it to stream audiobooks in tedious meetings.

In terms of hearing quality, for me, it's been solid, with the caveat that it took a while to get the fitting right. I think my audiologist was a bit old school, and was sticking to settings he'd known to be good in the past rather than fitting for what the aid is capable of. I've recently had its prescription type updated to the native Oticon one, and it's been a revelation in terms of clarity.

My hearing loss is relatively recent (About four years now) so I will caveat this that I've only used Oticons, so can't really compare to anything else.

Thank you for the new acronym. Sudden sensorineural (“inner ear”) hearing loss (SSHL), commonly known as sudden deafness, is an unexplained, rapid loss of hearing either all at once or over a few days. SSHL happens because there is something wrong with the sensory organs of the inner ear. Sudden deafness frequently affects only one ear. https://www.nidcd.nih.gov/health/sudden-deafness To save some people time if they were wondering.
