Sennheiser RS175 RF Wireless Headphone System $308 Delivered @ Addicted to Audio


Good price for AU stock I reckon. RRP $499 (JB hiFi still sells it at RRP, looked around prices are around $399)
Be careful when searching prices, some places showing good prices are only selling the headphone (with wrong product number), without the charger/signal stand.

These wireless RF Headphones for home listening receive glowing reviews, including audiophiles who are impressed by them.
Reviews & troubleshooting:
They are a bit pricey, so will mostly appeal to those serious about audio.
Radio Frequency Headphones usually have poor audio quality, static & interference, but apparently these headphones have high end sound & great signal, no audio interference.


  • High level sound quality
  • No sound delay
  • Great range performs surprisingly well through walls
  • Ease of Use (Just put them back on the stand every time you turn stop using them & never worry about them running out of battery)
  • Uses AAA rechargable batteries for easy replacements
  • Batteries are located 1 in each earcup to balance the headphone's weight


  • When using, you have to use switch it on. (Not the trigger in the headband like the sony version, which auto turns on by just putting it on your head)
  • Price
  • All buttons on right ear cup / difficult to distinguish (also tricky for left handers)
  • Slightly tight headband tension (better for smaller heads)
  • Button for switching inputs is on the base station. (Better design would have it on the headphones)

    A solution to Wireless control of audio for Apple users would be:
    1. Get a 2nd hand Apple TV 3 (off a friend or currently around $100 on gumtree).
    2. Connect to your TV then Reset the Apple TV to factory default.
    3. Set it up without using iTunes account (connect to wifi, make sure airplay is enabled [custom name airplay it if you want in airplay settings])
    4. Make sure Dolby Digital is set to "Off" (Go to settings>Audio & Video>Dolby Digital)
    5. Make Apple TV sleep (settings>sleep)
    6. Unplug from TV (HDMI)
    7. Connect to Sennheiser using Toslink cable.

    Now you can airplay to the Apple TV (You can name it Sennheiser Airplay) and control everything from your Apple device.


        Also a cheaper and more simpler option would be to buy an old AirPort Express for around $50 if your lucky (altough I wouldnt go older than 2nd gen Model: A1392, and you will have to connect through 3.5mm cable instead of Toslink optical, which may cause interference/static/poorer audio). I do not own an Airport Express so cannot speak on setup.

        This option is more appealing to those who have analog input equipment (Amp/powered speakers etc) as the 2nd gen AirPort is known to have a decent (satisfactory) DAC.
        The 3.5mm line out is known to be decent.


      …and control everything from your Apple device

      Could you please elaborate further on this?


        "Everything" referring to playing & control/pause/skip/rewind/select track (from your desired audio source[music app]) from iPhone storage or streaming service on iPhone audio which is being streamed to the Apple TV through AirPlay.

        This Apple TV 3 or AirPort Express (2nd Gen) method is a cheap option.
        Alternative methods would be replace the Apple TV with another Lossless wireless streaming device such as Yamaha WXAD-10 (RRP $229).

        In the past a kind of Digital Network Player (with built in HDD links below) existed,
        but due to high costs and introducing digital to the HiFi market early they did not sell.

        On these Digital Network Players "Everything" would have been done on the Player, not the smart device like in my example.
        (although some of them offered smart device App's to control the Player itself, streaming services would not have worked on these Players)


          Would an Apple TV2 work?


            @maruko: Apple TV 2nd generation does have AirPlay, but it must be connected to the same WiFi network as the smart-device you are playing from.
            Also after update 6.1 when playing AirPlay from smart-device for the first time, you need to enter a code which shows on the TV.

            I would recommend making sure the software update on the Apple TV is up to date (the last possible update, which is 6.2.1 on Apple TV 2nd gen [for stability and security). And if you are getting it second hand, perform a full factory reset on the device before using.

            Sound quality(supported formats) are the same as with Apple TV 3rd gen which I use.
            HE-AAC (V1), AAC (16 to 320 Kbps), protected AAC (from iTunes Store), MP3 (16 to 320 Kbps), MP3 VBR, Apple Lossless, AIFF, and WAV
            What file types are you wanting to play ? I will let you know that the main benefit of this is to achieve the maximum quality (CD quality - ALAC[Apple lossless], AIFF, WAV.) audio from your smart-device. (You may also notice a 'slight' improvement with MP3/AAC over 320kbps.)
            For everything else (MP3, AAC) the typical bluetooth wireless audio is sufficient.


            @maruko: There is a deal on the Yamaha product I suggested earlier.
            Although this only has analog (3.5mm or RCA) out just like AirPort Express (2nd gen).

            I would still recommend optical toslink connection over analog, as with a analog connection there is the potential for interference/static, which will be especially noticable through headphones.


    I really do like Rs ranges.
    Used to have RS170 and 180 for TV and computer.
    And I have 2 RS185 now.
    Great sound but its not that handy. It is wireless but the station needs power and 3.5mm jack to be hooked up.
    So if you planning to use with several stuff, it is not a good choice.


      Yep I went for the RS160 when they were around and it has the bonus you can put batteries in the puck and take it wherever. However in saying that it has rarely moved. Just the odd occasion has been handy


        Yuck. I had the RS160 and returned it immediately due to the hiss during music silence.

        I believe it was because the info was sent through RF. I don't know if anything has changed on that front.


          Hi thanks for you comments, many customers reviews say RS175 model is better than both RS165 and RS185 in all aspects. If I remember correctly only benefit of RS185 is it adds range.


          If you experience hiss it is likely interference from other 2.4ghz transmissions.
          I suggest attempting to troubleshoot the issue (repeating the pairing process and walking around the house with each process, until you notice no hiss). As far as I know you cannot manually choose the channels on the Sennheiser, so it is auto detecting interference and choosing a channel each time you pair.

          Many reviews on Amazon US for RS175 say no hiss whatsoever. This is how this product stands out.


            @margejsimpson: Forgot to add: RS160 may be similar the Sony RF headphones I own, where the hiss is unavoidable.


              @margejsimpson: I think it was unavoidable. Anyway, I no longer the RS160. At the time I had no wireless devices in the house other than my modem. The modem may have even had wireless turned off, as I ran Ethernet cable to everything. I turned it back on at some point for my then-gf, can't remember when.

      Lol it's one of the few wireless headphone systems that allow multi receiver connections. I have 3 rs170's and can connect all 3 to the one source. That's pretty handy in my book :)


        The limit is 2 headphones per transmitter for RS175.


          Yes that's why I chose the 170's for the 4 channels! But even 2 pairs is pretty good imo.


            @wolfshooter: I like the flexibility in having 2 base stations in 2 locations.
            The way we have it set up is, 2 people can listen to 2 different sources(1 is connected to pc/the other the TV), and at anytime join in so its 2 headphones from one source.
            (Although must say this may be easier with the Sony RF's, as they have physical switches on both headphone and base like this: [1-2-3].
            So you can easily switch channel to whichever base station)


      Hi the RS175 has both 3.5mm and Toslink optical inputs, but the switch is on the base station.. It would be nice if they had it on the headphones.
      Then you could at least plug in 2 devices and switch between them with ease(even have auto detect on inputs). I just went the route of buying 2 base stations for 2 headphones. On the Sony's at least you can switch between 3 channels both on headphone & base (to tune out interference and use 2 headphones with 1 base station/switch between base stations).

      I currently own two 3-4 year old Sony RF headphones, 1 base station hooked up to the computer, another to the TV, both still work to this day with a battery replacement. But the static/interference on the Sony's is a regular thing, unless you are completely still (even just by turning your head sometimes).

      I agree they are great for the computer, great audio compared to earphones/bluetooth, no lag like with bluetooth, and also you can get up to do something/use the bathroom while watching listening.
      No issues like with you have with earphones, being tied down to the pc, or having them ripped out of your ears.

      Regarding "several stuff/devices" use, these days I imagine people just hook up either a Amp and/or AirPlay/Sonos/Chromecast Audio/MusicCast Lossless streaming device. Then do all the controlling from their smart device. So 2 inputs seems reasonable.
