The GSP500 sound wide, wider than a closed back set by a lot. I had a longer one for my front door. They stretched easily over the ear piece and then bounced back into shape. Highly recommended, if you dont need wireless and dont want to pony up for elaborate "noise-cancelling" gear. Does fairly well at this. 0 plug-in adapter, which a lot of the competition did not include. This works great for hauling the speaker around, I?m not worried about it getting jumbled around the trunk of my vehicle where it usually sits until I need it. Con la tabella dei numeri è facilissimo ordinare la scarpa giusta! Note that these REQUIRE phantom power (most mixers offer that; but verify that yours does--this mic wont work without phantom power). Die Handyhalterung für das Fahrrad sieht qualitativ hochwertig aus.
