Blind details

This is a device designed from the ground up for blind hands and ears: a simple interface with large tactilely marked controls, high-quality Acapela text-to-speech where you choose the voice and the speaking speed, and an open folder system you organize your own way. It records from a built-in microphone or a line-in jack, plays back through its own speaker or standard headphones, and its manual is stored on the device itself as a text file you can read back at any time. Optional add-ons extend it further: the Fame color reader identifies colors and light, and the Woodscan barcode reader names grocery products.

Honest caveats: we could not verify a current US retail price in our research — older institutional listings put it near $449 to $475, so confirm the price with a dealer before budgeting. The color reader and barcode reader are separate add-ons, not included, and there is no Amazon star rating to lean on for this specialty device. As of October 2026.
