Sony MDR-RF865RK Headphone Reviews
Virtues
- Build quality, complete lack of background noise, excellent reception, long working time without recharging, sound quality.
disadvantages
- A little quiet, at full volume I want to make a little louder.
Comment
Bought this model a year ago. It still works fine, the battery keeps the stated time. The quality of reception at a height, the crackling appears only when leaving the balcony (through 4 walls). The sound quality for me is excellent, but it is a subjective assessment. You quickly get used to the good, now I do not have enough control buttons. It is very frustrating that in order to switch the track or to pause you need to approach the computer.

- Workmanship at a height!
- Nice, comfortable headphones with good sound quality.
- The thought-over design, convenient switches, volume control.
- For a long time enough battery power.
disadvantages
- Quite heavy and voluminous, but I quickly got used to it, do not crush, you can sit in it for hours.
- If the beep does not arrive for a long time, they begin to automatically scan the air and try to catch something, with some slight noise being heard.
- As tarantyl-73 already wrote, the volume margin is actually less than in wired headphones, but so far I have not had a single situation where I would not have enough of their volume, in most cases half of what it is.
Comment
I am very pleased with the headphones, they simply don’t have any competitors for this price - they bought for 3,150 rubles, and if you search, you can find them even cheaper.
P.S. When I chose, I looked at the Sennheiser RS170, they are really much lighter, but they cost twice as much as the mounts, on which the speakers are very flimsy - it feels like they can fall off during careless movement.

Comment
It took a headset to watch TV. Wiring is enough, so definitely wireless. I chose from Sony (trust in the brand + TV of their production) and Sennheiser (praised in the internet). The budget chose these Sony, because they needed two ears.
Then the most interesting thing began, when the question of how to connect them to the TV was diverged, even at the stage of telephone consultations, both with the store and the online store of Sony itself. Variants of answers:
1. Two headphones will work from one TV, but it depends on what you have transmitting base. ??? Yes, it is bought separately.
2. We do not know.
and a five-ball deaf phone with a Sony store itself. The girl replied that two ears will work, but a bluetooth adapter is needed. Fortunately, he himself guessed that he was not needed because the headphones do not use bluetooth transmission.
In general, the consultant said so at the company store - the transmitting base is bundled, you buy an output splitter from the headphones, and each base / headphone pair has its own channel (there are three channels to choose from). I put 2 channel on one pair, and 3 on the other. Everything works fine. By the way, on channel 1, the ears catch a good av station in parallel with the TV. At least in my apartment. On the 2nd and 3rd channel only each of them catch their base.The sound quality suits me, a slight background hiss stops with a slight movement of the fifth point across the area of the sofa. And by the way, bespectacled: the presence of glasses and ears put on top did not bother me. Totally. So far everyone is happy. We will use, if anything - I will add.

- sound, appearance
disadvantages
- spontaneous shutdown of the base and loss of signal when setting low volume on the source, a short base cord
Comment
The sound is generally good, but for amateurs, by no means for professionals. Both the bass and the middle ones are felt, lagging behind a lot, but you can play an equalizer.
There are glitches with loss of signal, when listening to a low volume on a computer, the base starts to turn off. It is necessary to set the maximum volume on the output device, and lower the volume already on the headphones themselves. If you forget and pull the wire, you can get full pants.
I tried to set 10% volume on my computer, played for 5 minutes, then the power supply diode flashes on the base and the base turns off. It happens that instead of the source catches the neighboring TVs and other radio waves.
Both problems so far solved the above method. Set the maximum volume on the sound source.
The wire is terribly short, you have to place it directly at the source of the sound and outlet.
Charging holds more than a week when working an hour or two a day, but I think it all depends on the distance from the source and on the volume, of course. You can stretch for a month.
They sit comfortably on the head, for a fragile girl it will most likely be hard, for the average man just right, the neck does not get tired for a long time.
You can freely shake your head without fear that they will fly off.
Pleasantly fit ears without pressing down the edges.
Ambient noises are suppressed poorly, you have to drown them with sound. I took to listen to music during the night work while homework is sleeping, so this problem is not significant for me.
For its price and with proper use with the above techniques work out with a bang.
I walk quietly around the apartment, and catches in the bath, located behind the ventilation unit, where wi-fi also loses half of its power, and the headphones work smoothly.
I recommend for home use when listening to music and movies at the amateur level.

- Material
- Lack of wires, but good connection with the base.
- Bad sound, BUT ... (see below)
disadvantages
- One big BUT, it is just the reproduction of some songs using some unknown noise reduction technology (or, as written in one of the reviews, this is the volume limiting system (AVLS))
Comment
In general, I would be satisfied with the purchase, and left the headphones, but this notorious AVLS system simply kills all the advantages of these headphones, so they were handed over to the seller without a drop of regret. The unknown technology really doesn’t turn off in any way, and apparently it’s based on the principle of signal transmission from the base to the headphones. However, this does not manifest itself as often as it may seem, in another review the sound was heard louder, then quieter (depending on the number of instruments being played, if one or two louder plays, the main theme begins - the sound is quenched). - I fully support, but this does not happen in all tracks, with a dynamic scene, so to speak, which I listened to, but only in some, which is especially annoying (by the way, when they returned they asked the seller to bring another headset - the result is the same).
The process of using (a little less than a week in my case) does not cause any complaints, they sit comfortably. The connection with the base is stable, the noise level without an input signal that the headphones catch is negligible, and when listening to something, it is not audible at all. The sound, in my humble taste, is of sufficient depth and width (if I may say so) again, if this volume limit is not activated.Headphones did not catch any extraneous signals at all, except that when switching the base to another channel, there were no problems with turning off the base (but I didn’t have that in my headphones and didn’t play anything for 15 minutes, listened to something, turned off the headphones, doing your work, no radio will appear, and the battery does not suffer in vain), if a signal goes to the base, then problems with connecting headphones did not appear, the sound appears almost instantly.
