Streamers allow you to wirelessly link hearing devices to other tech products, for example smartphones, tablets, or the TV. This means you can use your streamer to listen to music, or even apps such as Google maps and hear its directions straight into your hearing devices. And with most streamers you can make mobile phone calls. Many come with a wireless clip-on microphone, effectively turning the streamer into something that works a bit like a radio aid.
Streamers are often worn around the neck or clipped to clothing. They usually only work with hearing devices of the same manufacturer. For example, an Oticon streamer works with Oticon hearing devices, and Cochlear streaming accessories work with Cochlear cochlear implants.
