Query: Poor quality - avoid

You get what you pay for. This product works great - but only for a few weeks or months. I am on my fourth unit this year. Acutally, I'm not using the fourth unit as I decided to cut my losses and buy another brand. It works great in the beginning - light weight, comfortable, good sound. But after a few weeks or months, the other side will hear echoing and loads of static. I confirmed this by having someone use it to call my phone. This happened to all 3 units that I RMA'd, so it's no coincidence. The only saving grace is that Cardo is very good about replacements under warranty.
