The welded seams overlap almost an inch for extra strength. * Mic sound quality (to your receiving party) - excellent. It?s more flowy. The D9 unit comes already charged, so its plug and play. If you install this product into the studs it might be OK. Well made, no scratches, polished nicely and it was extremely easy to install. EVER! I could EQ the AT-8035 but I am going to keep the 416 and use it. Not only that but she loves them! Aber das optisch sehr schöne Riemenband ist von einer sehr schlechten Qualität.
