If you have older HA than Lumity, especially from before 2020 probably it’s worth to test Infinio without Sphere because of:
- better processing power - more accurate sound reproduction, more power efficient
- more reliable Bluetooth (Auracast-ready)
- better protection from moisture (reportedly as in Audeo Lumity Life).
- if you are with SSD (single sided deafness) - Infinio 90 without Sphere would give you maximum performance from CROS Infinio (Sphere doesn’t support it).
