The Echo MiniTech hearing amplifier is an in-ear device designed for use when loop system is in place. It features directional microphone and a replaceable battery for convenience. With the Echo brand's reputation for excellence in hearing assistance, the MiniTech offers a reliable and effective solution for enhancing sound clarity in daily living situations. Brought for husband to use for hospital appointments so have mark as used but was only taken out of box to test when brought then didn't have chance to use it. This model doesn't come with headphones, it's used with hearing aids when loop system is present. Have put batteries in to check it turns on. I have no idea how you set it up as I do not need hearing aids, it was my husbands.
