These strings are top quality and are very sensitive to vibration, meaning they are loud and responsive. They have a rich complex sweet sound that is also very clear, for someone that is learning the violin it's perfect because there is emphasis on intonation and they are soft to the touch due to their flexible design. These are great for orchestra players and soloists that prefer a full sound that is dignified and mature, they are synthetic core but do not sound overly bright or dull either. If you play happy bright music or more romantic period or modern music I would recommend Dynamo but if you are into more serious pieces than rondo gold is the way to go.
