So far, I was very pleased with how solidly everything attaches. The main units grip on our helmets without any problems and are well maintained in place using the standard installation process. The speakers fit perfectly and the boom mikes are surprisingly easy to position and are totally secure as well. There is no problem in using it in music. I haven't tried it with the phone or com yet. The sound is pretty loud. This seems to be a high quality product with great features at a very reasonable price.
This is by far one of the best purchases I have made, and the speakers are louder than I expected. I would, and have, highly recommend these for any rider.
Pelo preço é um excelente produto. Funciona muito bem, sem problemas de emparelhamento com o telemovel, a bateria tem uma boa autonomia e a qualidade dos materiais também é muito boa. Já apanhou com chuva e continuou a funcionar sem problemas. Recomendo.
