A noise is noticeable and can interfere when the signal source (PC, tuners, etc.) is too weak. If you as far down governs the noise of the amplifier of the earphone is not the volume on my headphones and the volume then levels off the unit also interferes with no noise and energy is saved because of the small headphone amplifier does not have to do much work with low input levels.
The range of the wireless earphone has proved ausgzeichnet. In the living room dr reception is always no problem, even through walls. But even outside of the reception is very good if you placed the transmitter on the window and then marched to the wireless headphones outdoors. So I can turn on the music in the living room and completely go around the whole 10 family house and without the tears off the connection to the end of de garden. Is only behind the big trees there mpfang like a badly tuned radio ;-) As the radio has a few problems but ds is fine.
The automatic shut-off after 2 minutes is also a great thing, which saves energy when the music turned out. Even while watching TV I can this wireless headphones good services, I can at least Tonmäßig noticed anything next time I'm short "on village" or in the Küch needs. For the price a great deal.
