Raised, shaped buttons with tactile markings make it easy to move to a new book, skip through chapters or review the paragraph you have just read. It has four large, yellow tactile control buttons, an extra large volume control dial, which is great if you have limited dexterity, and offers superb sound quality from the two built-in speakers. Whenever you switch the player off or remove a memory stick, the Sonic will remember the exact place and play from there when that stick is next used. The Sonic also has Bluetooth connectivity, so is ready for pairing with your mobile and tablet devices, too.

The Sonic unit must be turned on before headphones are inserted into the socket to ensure sound is only played through the headphones.
