Now that finally I have all elements together to actually use the device for its main intended purpose (most of the time it will be used as a music player) I had to discover that the base-level of noise is unacceptable high. It is impossible to listen to music with low volume, e.g. in a silent environment, as simply the base noise is filling your head. This of course depends on the sensitiviy of your headphones, but is already audible on my Koss Porta Pro (60 Ohms) and unacceptable on my CX-300 (16 Ohms). On my old Tornado (and even my Amadeus) it was just audible with the CX-300, but not with the Porta Pro.
I am much disappointed and only a very slight hope remains to increase the volume on one hand (the max volume is rather low compared to my Tornado) and decrease the sensitivity of the headphone on the other (serial resistor).
Sigh...
Seems to develop to a never ending story with this device :-( and I suspect that there will not be a happy end.
[Edit 20090108]:
I have not found any option in the registry for increasing the sound volume when the headset is connected. The sometimes reported action to set the valule in HKCU\ControlPanel\Volume to Volume=0xffffff is nothing but the place for the System Volume that is adjusted with the volume keys anyway. Even snapshotting the registry with and without headset connected and comparing these has not revealed an option.
As the noise level cannot be changed - and the volume not increased, I fear that was my short love story with this little gadget :-(
It still fits for anyone that has a lower sensitivity headset and does not require higher volume sound level there.

The crappy Battery levels on the BenQ E72
Did you notice that some report a bad battery life for this device? I did as well and there are several reasons possible for that - the most important one imho is the crappy battery level indication on the device (at least on mine - the BT-Fusion branded Version):
If you watch the Battery-Level in Windows, it reaches 100% already with a battery voltage of only 39xx mV - far less than a fully charged battery. Always watch for the green LED to indicate a full charge - this comes at 42xx mV as it should be.
This problem applies as well for the dis-charge: Any battery voltage above 3906 mV is reported as 100%. So you think the battery lasts forever - just to give you a bad surprise below that voltage. The Tornado is way below 80% here...
I still hope that this is due to a crappy battery.dll which may be a special version for the BT-Fusion device. In its intended use, it will eat more power than a normal device as it will scan for WIFI to connect a VOIP call via Internet if possible.
If you want to contribute your observations for a non BT-Fusion device - you can get the Voltage and Charge Percentage from the registry anytime at: HKLM\System\State\ or simply use the well known CeleTask option "Power Status".
If you know of a working(!) Batterymonitor that logs data to a file please tell me. My current idea is to create a MortScript that polls the registry and writes data to a file - yet no time to do that actually.
Edit 20090104:
In the meantime I have seen that the charge-level may not only depend on the batteryvoltage alone - see especially this link. When scanning the extracted files from the ROM dump, I have also found a huge bunch of possible registry entries in the battery.dll module. I will not try to debug their influence, so my only hope is that some other ROM contains a better charge-level calculation.
