How do I charge Sony wireless headphones

Sony MDR-RF895RK

Headphones with base station

Headphones that do not work with the Bluetooth radio protocol were the norm up until a few years ago, but are now the exception. And so these types of wireless headphones always consist of two “parts”: The actual headphones, which manage completely without cables and receive their signal via radio from a base station. This broadcasting station, in turn, should be set up as close as possible to the sound source and connects to the signal source via an (audio) cable. Normally, the connection is made with a television set or a classic stereo system.

Installation

In principle, commissioning the Sony MDR-RF895RK is self-explanatory: unpack, connect the transmitter to the television using the mini jack cable provided, switch it on and after a short synchronization the headphones are ready for use. After opening the box, however, I wondered for a while where the two rechargeable batteries should be placed. Unfortunately there was no instruction manual in the box and it wasn't that obvious. Research on the Internet showed that the left earphone can be "opened" and the slots for the batteries are located there. The operating instructions were available online.

For at home only

Sony specifies the range of the headphones as 100 meters. This certainly only works in the open field if there are no disruptive walls or other environmental influences that reduce the range. But compared to Bluetooth headphones, which usually shouldn't be further than five to ten meters away from the sound source, the range is considerably greater. At home I could still receive music from the upper floor of the house in the basement without losing the connection. Due to the base station, which is connected to the sound source via an analog cable, it is clear that these headphones are a living room device and not suitable for mobile use. There are two AAA rechargeable batteries in the headphones, which can be easily charged using the handle on the receiver. The charging time is very long at up to 23 hours, but the playback time is also very long at around 20 hours. The volume and the voice mode are set on the headphones, the receiving channel on the receiver.

Comfort

Unfortunately, the MDR-RF895RK did not sit very comfortably with me, at the latest after 15 minutes I felt the need to take it down again. The upholstery, which appeared soft at first glance, was no longer able to withstand the pressure on the ears. That is a shame, because the target group is above all typical living room listeners who want to listen to their classic standard players wirelessly, presumably over a longer period of time. So the head size is decisive here, so we recommend doing a wearing test beforehand.

sound

For a 100 euro headphone, the MDR-RF895RK sound okay, even if, above all, I lack some brilliance. On the other hand, the bass and mids are well represented. Unfortunately, I noticed some unpleasant compression effects, so that there was an unusual "automatic readjustment" of the volume when there were dramatic jumps in dynamics in a piece of music. I suspect that this is due to the radio technology used. The maximum achievable volume is very high and also helps those users who are hard of hearing or who suffer from comparable hearing impairments. For this target group there is also the "Voice" mode, in which the sound image is optimized for voice reproduction.
