OVERALL OPINION

I use it for 6 months.
I am not a professional.
He serves on scne in a jazz directory.
I used all kinds of micro, bottom-end inaudible to most of rpandus shure (pg 58, sm58, beta 58 ...) Sennheiser (E845, 945), peavey (pvm22).
While that of J'apprcie particulirement prodipe made for his voice trs trs clean and clear without deformation or the timbre or color. Compared to the Shure and Sennheiser was well above me parat.
Ct strength, it would be another few months to say more, but he trusts.
Report qualitprix excellent.
I do not regret my choice
