Property me both manuals downloaded and thoroughly studied.
Even when studying a favorite crystallized narrowly out: the Sony RF4000K due to the simpler handling / operation -dazu later.
The question was, however: he would be able to hold a candle in the practical test at the sound of the Sennheiser?
In Stupid market I can then show me in detail both headphones and tested. No surprise for me was that the Sennheiser has a really great sound.
I was surprised, however, that the Sony this inferior in nothing, in my opinion. I could not detect any differences in sound. I felt at both the middle of the concert hall! And both without disturbing noise, not even during the breaks -echt super!
So had to practice test, which makes the headset race: both headphones sit very comfortably, the ears are well enclosed. Unlike the Sennheiser (there can be volume, mute, 3D surround sound, bass and balance control to adjust directly on the headphones), the Sony has except the volume control any individual settings on the handset. Thus advantage of Sennheiser; but unfortunately, this advantage is somewhat clouded by the way this adjustment is made, namely through very difficult-to-use push buttons. Man pushes inevitably often the wrong button; Seniors should here have an almost insurmountable problem.
When Sony you can only adjust the volume through an easy-to-use thumb wheel.
Clear plus for Sony: it automatically switches on or off, as soon as one picks up the phone and puts on -great function!
Shortcoming, however: at the transmitter unit of Sony, only 1 headphones are connected, the Sennheiser there are even four!
Overall rating:
Positives:
- Super sound and noise-free thanks to digital technology
- Very good fit of the headphones
- Both batteries and AAA batteries can be used
- Automatic on / off the on / off placement of the listener (battery saving!)
-. Headphone turns out even when more than 10 minutes no audio signal arrives
- Elegant charging station (headphones not depends when charging around in the area)
- Transmitting unit turns off automatically when battery is charged (ie headphones can remain tucked away when not in use always there!)
- Volume control easy and simple by thumbwheel (no buttons)
- Automatically detects the optimum frequency when headphones from the transmitter unit is taken out, the previous annoying fumble deleted!
- Use of standard dry cell batteries, the charging function is not activated, ie the receiver can also be placed with batteries in the charger without the handset will be damaged!
- Reasonable price
Negatives:
- Only max. 1 headset can be connected to the transmitter unit
- No detailed adjustment of balance, mute and surround right on the headphones
Makes 4 stars with tendency to 5 stars and a strong buy recommendation for the Sony MDR-RF4000K, for I have now decided.
Full 5 star would have given it if more than 1 headset could be connected to the transmitter unit and if he had more settings (balance, mute, etc.).
Case anyone is interested: a detailed rating from me for Sennheiser RS 170 can be found there.
