This is a difficult question to answer as it depends on personal preference. If you are using the microphone for live performances, then it is probably best to keep the cables as short as possible and wrap them around your arm like an extension cord. However, if you are using the microphone only for recorded audio, then it may be better to wrap the cables over your hand instead of around your arm. The main reason why wrapping the cables around your arm can cause interference is because the metal wires will rub against each other, which will decrease their signal quality.
