Sound is quite ok, but second star

The micro is very bad, my cheap 10 headset sounds as better. If you switch the headset on (about 4 sec power - slowly blinks red), it beeps deutlisch audible very high on the right side. In pairing mode not (about 6 sec, green light blinks red) strangely. If a Bluetooth connection is then made, the headset begins again on the right side to beep, partly something like tickers, like old 56k modems. Wrote to the Mr Plate, whether this is a defect, or normal, so far no answer .. Maybe someone knows here on this subject a little more precise?
Unlike other comments I could connect it to Windows 7 64bit, but have also tried many drivers, until I remembered that I sekunedn the power button for pairing 2 Änger hold must .. Maybe there at all A2DP drivers hang something geblieen that it works for me and not for others. Have me extra one newer Bluetooth dongle purchased could also be due ..
The sound is very good as long as you can hear something, this beep falls even less. That's why even 2 stars.
From the comfort of her there are worse reactions that feels AEG actually quite good at.
