# How can I fix issues such as noise, echo, and poor voice quality?

The first basic requirement for good voice quality is a **broadband internet connection**. What is important here is the speed: A single phone call over the internet requires about **100 kbit/s** (in each case for upload and download). Too little bandwidth can lead to dropouts.

* **example**: Even with a standard DSL connection with 16,000 Mbit/s download and 1 Mbit/s upload, up to 10 parallel calls are possible.

Your internet connection is fast enough and yet it still lags? Here is a list of possible problems and solutions:

* **A cable is better than Wi-Fi:** It sounds like a rule of thumb, but it is true in most cases. If the router and computer are connected to the internet via network cable, you get more out of your bandwidth.
* **The right headset:** There are many good Bluetooth headsets. Nevertheless, headsets connected by cable are usually faster.
* **Strong interference noises on the line:** If your voice is accompanied by strong interference noises, check your microphone settings under **Start -> System Settings -> Audio Settings.**
* **Audio input and output:** Maybe your audio settings are not quite correct. For example, you hear the phone call through the computer speakers even though you have a headset connected. In general, you can select the appropriate audio input and output for your respective device in the system settings of your operating system and also adjust the input level - that is, how sensitively your microphone should respond.
* **You hear yourself and double?** This is usually due to your conversation partner(s). They hear you so loudly - perhaps through computer speakers - that your own voice comes back to you through the other person's microphone.
* **It still echoes?** You have already checked all technical settings and your conversation partner still perceives you as echoing? The first option would be to lower the input level of your microphone (in the system settings of your operating system). Another solution may sound a bit banal, but perhaps you are making the call in an unsuitable room. If there is generally a lot of echo in your room, then unfortunately even the best technology will have a hard time compensating for this problem.
* **Echo on your conversation partner's side?** Of course, your conversation partner(s) could have the same problems described in the previous point. But perhaps they are also using speakerphone. The microphone on the phone is then often very sensitive so that the person can put the phone aside and still be heard. However, this also means that you will hear more of the room, including echo, more loudly.
