Positives:
First, it should be mentioned that both the headset with me (average head size) as well as with my friend (relatively small head size) is very well fitted and was comfortable to wear. In addition, the sound quality was also difficult in order. Likewise, the bass and surround function. The removable ear pads are also a nice touch.
Negatives:
Unfortunately went by, at first glance relatively solid headphones along some negative aspects. On the one hand, the buttons on the headphones are very difficult to distinguish from each other. Do they feel, like a big button, which greatly impairs the operation, if you do not settle the headset or switch on the transmitter unit. Secondly, the entire headset is very unstable due to the thin plastic headband and wobbly joints.
The connection between the headset and transmitter station was initially stable. However, when we tried to use two sets of headphones at a transmitting station, there were major problems. On one hand, the switch from a headset per station was complicated to two headphones to a station unnecessary. To accomplish this fairly smoothly, you must first turn off all stations (in the time of course you can not use the headphones) and then by pressing the power button (for several seconds) to connect to headphones and Station, both with each other. This needs to be repeated for the second headset. If that worked, which is apparently not a given, you can switch to the station used on several headphones. One finally provides both systems back to individual use to, it can happen that a headphone between the channel changes to the other broadcasting station, since it is apparently not connected to both stations.
The problem that the headphones have but eventually rendered useless (for me), the wireless connection is lost. When you switch the headphones and sometimes while using the Wi-Fi signal is repeatedly stopped completely. Well one more problem when wireless headphones.
Conclusion:
As noted, we would even keep the headphones probably when those pesky wireless terminations would not have been. So we had nothing but the returning left. The wireless headphone system makes some good, but the serious shortcomings make the product in my opinion not recommended. In general, I would have in this price range (~ 150) more expected.
