My Widex Clear Passion 440 were top on the range at time, Bluetooth enabled. I have found these aids to be pretty reliable and quite versatile. Easy to use, put them in in the morning, remove last thing at night. Quite heavy on batteries (they are tiny!) about 2 -3 days each amounting to approx 60 batties over 3 months. Most of the time I don’t even use the remote control unit other than when attending social events or when driving as it is offers hands free operation. It was expensive at the time costing a net £4000 for the pair with a 25% reduction. I now insure annually @ £160 and I would suggest this is necessary as from time to time repairs have been needed. They are very discreet and few people are aware I am using them. I only use its ‘music’ settings on rare occasions (concerts possibly) – not sure if I notice any real difference with capability.
In the case of social events it is of great assistance with its directional pick up facility. The Bluetooth facility using an HTC smart phone is less reliable as the software quite frequently fails leading to silent calls where neither party can hear the other.
Prior to using hearing aids I know that my poor hearing impaired my work quite often and social occasions were misery as trying to pick out individual voices in a group of people was difficult and tiring.
For the future I would like to see better software, possibly getting rid of the controller altogether in favour of a smartphone app that would be even more discreet and probably improve the reliability with the phone connection. I would be interested to hear other peoples experiences.
