excessive noise and low volume

1. Noise
The headphones rushes on both broadcast channels, regardless of the output device. Charged batteries and turning up the volume on the television bring here anything.

2. The volume
I find it quite well when manufacturers produce their audio devices so that you will be deaf not immediately in use. Philips has it then but clearly exaggerated here, the volume just reach low volume, for my grandpa (for the headphones were determined) unusable.

3. The battery / batteries
Only Philips-sleeved batteries used actually, because the contact is not the end, but on the ground. Not particularly tragic because matching batteries are included, still annoying. Anyone who wants to use other batteries need a short ran with the knife.
