I have had them for about 18 months now. They are very successful for speech and make a big difference in conversations and meetings, though the ‘cocktail party’ is still a challenge. The iPhone control is very useful if a bit ‘beta’. The main annoyance is that for me they are useless for listening to classical music. They shift the frequency down about 30 cents, even when the audiologist switches off the frequency shift settings. It sounds poor but tolerable when listening to streaming (iTunes etc) but when listening to or playing live music, there is an audible clash between the sounds heard live and those heard through the HAs. I switch them off for music. My hearing loss is standard old age (80), quite good up to 1 KHz then rolling off rapidly, 60 db down at 3 KHz, so I hear vowels well but not consonants.
They are very good for use with the iPhone for calls, putting the sound right in your head. It is frustrating that they cannot, as far as I can see, be paired directly with a Mac to hear sound from the computer directly. With the plethora of online Zoom, Hangouts, Teams etc meetings at the moment this would be very useful. Does anyone know how this can be done?
