Our take on the Sennheiser RR 840

Add an extra pair of these RR 840 headsets to your Sennheiser SET 840 TV wireless TV listening system and share the fun. These lightweight receiver/headphones use flexible earbuds that rest just inside your ears for hours of comfortable listening. A single charge of the receiver's battery provides up to nine hours of use.

Product Highlights:

  • add-on headphones designed exclusively for use with Sennheiser's SET 840 TV and SET 840 S wireless TV listening systems (sold separately).
  • RF wireless receiving range: up to 100 feet
  • built-in volume and balance controls allow individual settings for each headset
  • automatic turn on/off conserves battery power
  • frequency response: 50-16,000 Hz
  • rechargeable battery (included) provides up to 9 hours of operation
  • includes 2 pairs of replacement ear inserts
  • weight: 2.4 oz.
  • warranty: 2 years

What's in the Box:

  • Wireless headphones
  • 2 Pair of Silicon ear-inserts (black/white)
  • 1 Pair of foam ear-inserts
  • Instruction Manual

Does not fit easily with hearing aids which is understandable, but ear pieces could possibly be more adaptable to hearing aid type "ears", perhaps a cover-over design. Love the Crutchfield units as a wonderful aid.

Product Research


Overview: The Sennheiser RR 840 wireless headphone is specifically designed for use with Sennheiser's Set 840-TV and Set 840-S wireless TV listening systems (sold separately).

RF Wireless Range: The Sennheiser RR 840 wireless headphone provides a wireless mobility range of up to 100 feet from your Sennheiser TV listening system. It can transmit through walls, so you don't have to be in the same room as your TV or audio system.

Stethoscope Design: The Sennheiser RR 840 wireless headphone features a stethoscope design.

Comfortable Fit: The lightweight RF wireless headphone is comfortable to wear because of the flexible earpads that fit inside the ear.

Ergonomic Controls: There is a large, ergonomic volume control on the stethoscope-style headphone to adjust volume level. There is also a balance control on the headset to adjust the balance so that you hear equally well with both ears.

Integrated Rechargeable Battery: The RF wireless headphone features an integrated lithium-polymer battery to ensure a long operating time of up to 9 hours. The headphone charges when it is rested on the Sennheiser TV listening system's transmitter/charging station (up to 3 hours).

Note: It can be placed in the transmitter's charging compartment facing in either direction.

Auto Power: The RF wireless headphone automatically turns-on when you place it in your ears and automatically turns-off when you take it out (after 30 seconds).

Note: If you are not within the range of the Sennheiser TV listening system's transmitter (sold separately), the headphones automatically switch off after 3 minutes.

Crutchfield asked  
Why did you buy this?

We have the Set 840 and would like to use a second headset. [ Steven  Jan 24, 2018 ]
I baught it 4 years ago and lately, I can ear only on one side, the silicone tip fall of and a full charge last only an hour about. It seems to be difficult to order just the tips. Is et reparable? Constant Archambault [ Constant  Nov 23, 2017 ]
The first set worked so well, I bought another so my wife and I could watch late night action adventure movies without disturbing the kids' sleep. [ Charles  Mar 11, 2017 ]

1 question already asked

This particular system does cut out the TV sound (this is what we wanted). But Sennheiser has another system which does not; their customer service reps are very helpful in answering and advising. BTW, I am very happy with the sound quality, far superior to a previous highly advertised brand. [ Jona  Jan 16, 2014 ]
The person not wearing a loop can listen from the regular speaker. But the good news is that the you can "mute" the TV speakers while someone else is listening through the loop which is great when, for example, someone wants to listen to a sport's prgoram that you do not! This is a great system. Even if you are not hard of hearing, having a second loop is great because you can walk around the house and listen to the TV program from other rooms. [ GEORGINA  Jan 07, 2014 ]
A lot of your question depends on your TV's audio outputs and menu options. I plugged my RR840 into the Audio Out RCA jacks of the TV, and my wife can hear the audio through the normal TV speakers. However, I think that if it is plugged into a TV headphone jack, it might mute the speakers. Warning: The RR840 is a great concept and I really liked the lack of isolation, but the headphone is so flimsily made, that I've had to replace two in a short period. I finally gave up and went to a Sony RF unit with over-the-ear headset. Much more isolation, but they should last a bit longer than a few weeks over the warranty period. [ Carey  Jan 06, 2014 ]
One further point: There is a volume control on each RR840 headset. Thus, when using two sets of headphones with one transmitter, each wearer can set the volume to different levels. You first set the TV volume at a comfortable level before plugging in the transmitter. Them, put on the headphones and set the volume on the headphones wherever you want it. [ BARTON  Jan 06, 2014 ]
Plugging in the RR840 does cut off the speakers. There are two ways to handle this issue. First, you can buy a second headphone from Crutchfield for about half the cost of the total RR840 transmitter and receiving headset. Both sets of headphones can receive from the same transmitter. The second headset is listed as a spare part.. The second way is for your husband to investigate hearing aids that Bluetooth into your TV. these are available from a number of suppliers, Widex is one. Your husband should probably have hearing aids anyway. I am such a husband, but I prefer hearing aids without the Bluetooth feature so I use the RR840 along with my wife who is not hard of hearing. [ BARTON  Jan 06, 2014 ]
The unit has RCA connections (red/White) that connect to your TV in the back. If you use these connections the sound will still come through the TV speakers as well as the headphones. Some TV's also have a small plug in "mini-jack" for a connection..typically if you plug anything into this jack it will disconnect the TV speakers. So the answer to your question is if your TV is more modern and has RCA jacks in the back you can use these Sennheiser headphones and still hear the sound from the TV speakers as well...simulataneously.
