3pcs DIY High Fidelity Deaf Hearing Aids Audio Amplifier Kit Digital Amplifier Board Module
A part of the review has been auto-translated.
small.compact.portable. battery included as well. earphone you should supply. would be nice if circuit schematic is included.
I received the package pretty quick with EU Priority Line method(in about 2 weeks). I assembled all the components and it works. It may not be the most efficient one but it works just fine.
Works fine and price is unbeatable; only the battery is normally more expensive than the whole kit. A little bit more MIC sensitivity would be desired, but operation is quite acceptable.
decent product but condenser mic needs to be sensitive to pic sound from at least 2 metre
works great thanks
Nice
