My correspondent hears me very poorly or not at all when I use a hands-free kit

When you use a hands-free kit, you must first verify its compatibility with your device. 🔗

While Macbooks and recent laptops 💻 provide three connections (2 for sound output and 1 for microphone input), older laptops have two different connections, splitting input (microphone 🎤) and output (sound 🔉).

If your laptop has an integrated microphone, this will be the main one, meaning you'll have to stay close to it. If not, you'll have to connect a microphone via jack 🔌, a USB microphone or a USB headset.
