All in all, Id give them a 8. I am using a "self made" pink noise track. This is also my first bluetooth headset so I cannot say how it performs compared to other products. phone was exactly as advertised. i have helmet cams, so havent used it for that either. Horrible instructions and the software for the mac doesnt work at all for the firmware upgrade. I expect this level of quality and service from a sub $100 bar but at $220? Llegaron mucho antes de lo previsto hasta Nayarit ?? El material es comodo y no se me nota con ropa oscura. A couple of years ago I ordered solid black, gold and silver Havaianas and they all were true to size.
