Since this headset has been sufficiently evaluated only a summary: Very good balanced fuller and spatial sound, no noise sounds as often unfortunately with other manufacturers, there is no signal abort when you have just in the next room or the door times, ease of use and setup, and pleasant "wearing ". At least for me no disturbances occur in phone or Wi-Fi network. Although the home network PCs, printers, tablet and Smartphon and Horizon TV-Box and wireless phone are integrated. There are up to four pairs of headphones on the transmitter coupled (not available from any other problem). Very positive pluses: The extremely low power consumption in standby, the smart dissolved Application procedure at the base and Sennheiser packs all necessary analogue plug or adapter in (RCA jack). Clearly highly recommended, although other comparison sets often are slightly cheaper. In this division Sennheiser is obviously not without reason "tone stating" here or sound-tampering. Fast delivery and low price on Amazon.
