Not every phone that says “Hearing Aid Compatible” works well with telecoil/Ha’s, tis a bit of a lottery as many are poorly made or not compatible to the clients loss, some you can alter the voice tone as well…which helps!
Here in the Highlands of Scotland we have a “Deaf Services” drop in centre, I once worked there, they have loads of environmental aids, smoke alarm systems, flashing doorbells etc’, maybe a dozen or more different “Hearing Aid Compatible” landline and six or so mobile phones for HOH, also some minicoms for Profoundly Deaf to try out, one size does not fit all HOH as everyones loss is different, tis a matter of trying each phone until you find one that is suitable for the client! BTW, this Deaf Service centre has an 98% total satisfaction from client feedback forms, they do a wonderful job and the look of sheer delight on a clients face when the can hear a loved one on the phone, maybe the first time in years, I have actually had many clients cry with joy…
I should know better, but last year I ordered a Geemark Amplideck 250 cordless phone via the internet without trying one out at Deaf Services first, this phone is made for HOH, tis as much use as a chocolate fireguard to me, I can hear ten times better on my VOIP phone at work, which is not hearing aid compatible!!!
Good luck in getting a phone for your mum Theirry! Cheers, Kev.
