Hearing aids have undergone a transformation in recent years and with the introduction of digital technology large, old-style hearing aids have been replaced by models that are simpler, smaller and smarter.

Generally hearing aids have a built-in microphone that picks up sound. This sound is processed electronically and the resulting 'sounds' are passed to a receiver where the 'signals' are converted back into clearer sounds that you can hear.

With smart technology, hearing aids also have the ability to be paired with digital devices so you can stream sound directly to your hearing aids from a mobile phone, ipad or TV when using DEX accessories - making you in control of what you want to hear.
