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.

Headset was Great!!

Crutchfield Customer Review (What's this?)

This Sennheiser RR 840 headset works great!! Allows my wife to listen to her shows on TV with sound muted so it doesn't bother me at all. Crutchfield got it to us in only a few days!!

Pros: Efficient, quiet, light and with good ear caps!

Cons: None.

Great hearing

Crutchfield Customer Review (What's this?)

These are outstanding for hearing the tv. You can adjust the volumn. I just wish I didn't have this hanging in front of me. You won't find a finer product on the market. Pricey but priceless to hear what the people are saying on the tv. You can move from room to room with no interference. Now my husband gets caught using it when I put it down or if a family member comes over to talk and he can't hear the tv. on goes my ears. But you must get the 840 as the other one did not work for me. You will love them.

Impressive TV headphone system

Written By Harry, Marine City, MI on Thursday, April 04, 2013

Crutchfield Customer Review (What's this?)

Got tired of constantly repairing our TV Ears headphones. I purchased this RR 840 extra headphone as a backup for our one-year-old 840 TV Headphone and Transmitter set. The Sennheiser simply blows TV Ears out of the water for construction and performance. The sound reproduction is hi-fi quality that makes musical programs on TV a joy to watch. The Sennheiser operates flawlessly even if you wander from room to room. No static or sound drop.

Pros: Multiple tone settings delivers superior sound for voice or music programs from your TV. BIG volume control makes for easy adjustment. Automatically shuts off after 30 seconds of non-use to save battery life.

Cons: A bit pricey, but it pays back with absolute satisfaction.

Super help for hearing impaired

Crutchfield Customer Review (What's this?)

My wife has used other brands of tv listening devices. This is the best ever. We
have two systems on two TVs plus an extra headset. She uses the headsets set
to a comfortable volume for her while I set my volume on the Bose home theater
system. She can roam the house and still hear the TV. One other brand was
picking up noise from the screen that I could not get rid of. We are very happy with
this product.

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.
