Earbuds with mic

Buy offer Details

Dear Sir/Madam,
This is JamiePell from UK.
Im looking for products with the following specifications :
A small, inner ear ear device, which looks similar to the picture attached (Hearing aid). Meaning it looks exactly like a hearing aid. However, instead of amplifying sound I would like the device to echo the words in what the user is saying, at a slight time delay (microphone needed). The time delay can be discussed later regarding the actual time and the option for being able to adjust the affect. I am only looking for prototypes at the moment, but I will increase economies of scale when I find the right supplier. I would like it to be good quality and be equipped with either spare batteries OR rechargeable (Rechargeable would be better - can discuss later).
When I find a reliable supplier, I will also look to expand the product base so that I can have an around the ear option as well.
If interested, please get in contact so we can discuss budgeting ,economies of scale, shipping requirements, delivery time and more.
Thanks.
