  1. Really great for treble of classical. 5 Star Review

    Posted by on 2nd Apr 2018

    price not as low as most of people want, but it worth it. It is grogerous on piano and violin sonata, great for symphony also. need better bass tho.
    Still, If you are into symphony, sonata, or female voice which are mostly treble sound, it wont disappoint you. overall it is also clearer than t10i which i used before.
