Have they improved much over the past few yeasr.

They can recognise your favourite restaurant
Modern digital hearing aids are self-learning. That means they get to know your preferred settings for places you go to and adjust automatically.

They know when youre having a one-to-one conversation
Our hearing aids dont just turn up the volume, they identify the sounds you want to hear and filter out the ones you dont. So even in a noisy room, you can hear the person youre talking to clearly above the background chatter.

They can help you watch TV
Special technology can send the sound from your TV or stereo direct to your hearing aids. So you can easily hear your favourite programmes or listen to music without disturbing others.

So clever, they can answer your phone for you
With a discreet remote control in your pocket or handbag, you can answer your mobile phone at the click of a button. Youll enjoy clear conversations as you listen to the call through your hearing aids.

They even listen to each other
At Specsavers we give you two hearing aids for the price of one, programmed to work together. So when the settings in one hearing aid change, the other responds to give you perfectly balanced, all-round hearing.

Is all if this true or is it marketing hype?
