Not bad 604

Very good sound. The best outfit I've found for 2 years, and sports helmets, I bought. The arch gene a little with the glasses and we must test the various bits provided to find the listening comfort. However, the helmet stays in place even with perspiration and that's an important point when we over time.
Super light. Perhaps one of the hoop stiffness chouilla less would be welcome but good.
The clip to hold the remote control is also useful.
Frankly good acquisition at a reasonable price.
UPDATE 28 October 2014: headband made for a "small" head, otherwise it twists and headphones do not take up. Trying lécarter slightly, the arch has broken, so quite fragile. Too bad, the product deserves a little more flexibility.
