Sony MDRRF811RK wireless headphones black Product no.: 9000-0021-2907 Warranty period: This product comes with a 3-year warranty.


These headphones have a wireless range of up to 100 metres, which is plenty for use at home. 40-mm drivers ensure a clear and detailed sound reproduction. With a frequency response of 20 to 20,000 Hz, the mid and high frequencies will come through best, which makes them ideal for Classical music in particular. On a fully-charged battery, you can listen to up to 13 consecutive hours of your favourite music. The battery takes about 16 hours to charge once depleted. These headphones have a closed construction, which means they effectively counter ambient noise as much as possible. The headband adjusts itself to the shape of your head, and a wireless receiver is easily connected to the desired source by means of a stereo mini jack connector. An on/off button is located on the left ear pad, as is the adapter to recharge the battery. A green or red LED light indicates the battery status. On the right ear pad, there is a volume control and a button to switch between the two wireless channels.
