those string a very good in terms of projection , precision and details.
They are great for soloists but unfortunately they loose their sound after a very short time , maybe few days to few weeks.
they are still good choice for an important event , and audition , a concert or a masterclass and their break in time is very short. i don't recommend if you are low in budget as they are not a good economic choice.
i give 5 stars as they still bring a great sound and quality.
