As part of the decision making process for deciding on a Bluetooth headset to use with my Motorola V710 phone, I read the user reviews from here and various other web sites. Although there were a few less then stellar reviews, in general people seemed pleased with the Scala-500. So I wend to Cardo's web site to look at the specs and features to ensure that this headset meet my needs. Seemed like a nice light, comfortable headset with decent features for a good price. Much to my delight the Scala-500 was at my door step two days later. This is where the disappointment begins to set in. Upon opening the package, I found my Scala-500 with its speaker hanging off of the main unit, tethered by one of the two wires. Not only had the speaker popped off, but one of the speaker wires had broken away from the soldered joint. Giving Cardo the benefit of doubt concerning the quality of their headsets, I called the company it was purchased from, received a RMA # to return the headset, and purchased a replacement Scala-500. Two days later, when I received the second headset and opened the package I was disgusted. This Scala-500 was in the same condition as the first, minus the solder joint issue. The speaker was popped off and tethered only by the speaker wires. So did I get the only two defective Cardo headsets? I doubt it!!! This headset design if flawed. If you own one already, then expect the speaker to fall off and be out $40. And if you're considering buying one then know that you will be buying another headset in the near future.
