I purchased what was described as an in-ear hearing 'aid'. When I received it and tried it, it transpired to be a hearing amplifier NOT a hearing aid. This meant it did not reduce background noise eg music and focus in on speech. Instead everything was amplified! I e mailed the company to request to return and receive a refund. Initial response was to give me instructions on the correct use. a couple more emails later I was advised that I was not entitled to refund only exchange. I actually had to contact consumer rights and trading standards who gave me an officially worded letter template. After sending this to them they agreed to refund me. Beware as amplifiers can actually damage your hearing further. Interesting the review I left on their website is not shown.
