OVERALL OPINION

I have a couple of 2 B3. Nothing wrong for the price.
I possde an audio technica 4050, and well since the acquisition of the B3, it stays in its box!
For the price you risk nothing, if n 'is that to have a good micro trs.
And if c 'silent again, I n buy not 4050!
I should have 10 well-dressed, but a 9 will be fine!
