I bought the Jabra Earwave Boom as an upgrade from a cheap-ass generic earpiece. As i hoped, it's a much nicer product. It feels of decent quality, and it fits on/in my ear very well. It also looks quite cool, i think. Sound quality, in both directions, seems to be quite good.However, my #1 complaint is that it is TOO LOUD!! Maybe it's just my phone, but with my Samsung i500 smartphone, even with the volume turned down to the minimum, i kept wincing as my ear would be blasted. Even the 'beep' after the 'Who do you want to call?" voice dial query would be painful.However, i did find a solution. I took a tiny chunk of soft foam taken from some packing materials, and stuffed it into the audio canal through the eargel with a pin. It blocks enough sound that the Earwave Boom is comfortable to use.If it had come with a reasonable volume level out of the box, i would have given it 5 stars.
