Cons:None so far. The outlet I was trying to plug into was an upgraded outlet that I installed a few years back. Has 4. Attach the pad with the indicator on the outside of the headphone (line it up with the L and R printed on the outside of the ear cup) and theyll snap right in. This gets ripped out here and there and then when that happens, you have to take the headset off to attach it again. Its a poor concept, and very poorly executed. I will update this review in the future regarding its durability and thats the only thing Im concerned about. Im Gegensatz zu Konkurrenz kein Registrierungszwang, reibungsloses Firmware-Update und tolle Konfigurationsoptionen für die Funktionstasten. what im left to conclude is that all of the ear tips included with this product are poorly designed. Am airing it out now.
