Our take on the Sennheiser RS 135-9 by Crutchfield's Jeff Miller
Watch TV or listen to music on your own time
Plug the transmitter into a 3.5mm minijack audio output on your TV or a headphone output on your stereo system.
As the parent of a three-year-old, I have to pick and choose when I watch my favorite special effects-filled TV shows. It's not like I can turn on Game of Thrones in the middle of playtime. The Sennheiser RS 135-9 wireless headphone systems lets you watch TV with exciting, detailed sound, even when others are asleep. (The wireless transmitter connects to your TV's headphone jack or analog audio output.)
The on-ear headset has an open-back design for spacious sound from movies, shows, and music. Some sound does escape. But they're certainly more sleep-friendly than blasting the volume on your TV or stereo system
Huge wireless range and rechargeable headset batteries
You plug in the included transmitter the same way you would connect a set of wired ‘phones. It connects to your TV's stereo RCA or 3.5mm minijack audio output, and you also get a 1/4" adapter to accommodate a full-size headphone jack on a stereo system. The radio frequency (RF) transmitter has a maximum range of 330 feet and can send its signal through walls and ceilings. The headphones are powered by included "AAA" rechargeable batteries. With the batteries inserted, just hang the headphones atop the transmitter and charging will automatically begin. You'll get up to 20 hours of use with a full charge.
Soft padding and earcup dials for easy control
When you're binge-watching TV or listening to music for long stretches, comfort is key. The RS 135-9's lightweight headset features soft cloth earcups that rest on your ears. Extra padding lines the top of the headband. The volume control is built for leisure, too — it's located on the right earcup, along with a tuning dial to keep the wireless signal strong, so you don't have to get up to make adjustments.

Sennheiser RS 135-9 Reviews
Average Customer Review(s):
Thanks for submitting your review
Overview: The Sennheiser RS 135 RF Wireless headphone system consists of a pair of wireless headphones (HDR 135) and a radio frequency (RF) transmitter (TR 135). The system is designed to enhance the sound of your TV or home audio source, and to give you the freedom to walk around your home with the headphones on.
Wireless Headphones: The HDR 135's wireless headphones feature an open, supra-aural (on-ear) design. The soft-padded ear cups and headband provide hours of listening comfort. The headphones have the power control left ear cup, and volume and tuning controls on the right ear cup. Two charging contacts are located on the inside of the headband. With the batteries installed, the HDR 135 headphones weigh 7.9 ounces.
TR 135 Transmitter: The transmitter connects to your television's or audio system's audio output via the attached RCA cable (82" length). The audio is transmitted on the 900 MHz band (926.15 to 927.55 MHz) with FM stereo modulation. The extended transmission range is approximately 328 feet (100 meters) with reception through walls and ceilings. The transmitter is powered by a 9-volt DC power supply/AC adapter. The transmitter features a convenient charging stand for the headphones that extends above the top of the transmitter. Two keyhole slots are provided on the back to allow you to wall-mount the transmitter, if desired.
Audio Connections: The transmitter has an attached audio cable with stereo RCA plugs. Two adapters are included: a female stereo RCA-to-male 3.5mm (1/8") plug, and a female 3.5mm-to-1/4" (6.3mm) plug.
Rechargeable Batteries: The headphones are powered by two (included) "AAA" rechargeable NiMH batteries (1.2V, 600mAh). The batteries fully charge in approximately 18 hours when placed on the charging stand. Typical battery life is approximately 22 hours of use. Standard, non-rechargeable "AAA" batteries should not be used in the headphones.
Additional Headsets: The optional Sennheiser HDR 120 wireless headphones, sold separately, can be used as a second set of headphones for the RS 135-9 system. They operate on the same frequency band with FM stereo modulation. Multiple pairs of headphones can be used simultaneously with the RS 135-9 wireless system.

Mobility. If there is a way to get better fit of the ear muffs (they fall off sometimes when I bend to do housework), this tool would be perfect! [ JOANETTE Nov 28, 2016 ]
Used for smaller TV in separate room from main TV that has a Yamaha receiver that can output audio to Bose Bluetooth earphones. Now in smaller room TV that does not have earphone jack can use a wireless earphone set with similar results when needed and no need for a separate receiver with earphone jack which would be overkill for my needs. [ Don Nov 25, 2016 ]
BUDDY SAID THESE WOULD DO THE TRICK!!!!!! [ N Oct 05, 2016 ]

Need a headphone [ Bernd Apr 29, 2016 ]
The wireless head set or one like it was seen in another house and looked like a well put together product. We seen it at another web site, but they were out of the product, so we seen your web site with the RS 135-9 and you had it on hand, so we bought it from you. Thank you! [ Bradley A. Mar 29, 2016 ]

2 questions already asked
I don't think so, I have mine connected to a Home Theatre set, and have to turn down the sound from the Amplifier/Receiver to use my head phones. Also, the head band on mine does not "fit" tight enough; and if you move your head a little too quick, they fall off! [ Dennis Oct 30, 2017 ]
Yes, volume directly from the television is independent of the headphones. The headphone wearer can adjust to suit his or her preferences, and the other people in the room can adjust the volume of the television -- one does not affect the other. [ J Christopher Oct 30, 2017 ]
I purchased these as a gift. They plug into the aux. Not sure if that would shut off the sound on all TVs. If you had more headsets/reievers they should function. An aux adapter would allow a wired. Headset to be connected. Hope that answers your quuestion. [ Kenneth Oct 30, 2017 ]
YES IT SURE IS. [ CLAY Oct 29, 2017 ]
Absolutely. Most modern TVs have audio outputs (RCA type) that do not cut out the TV's speakers. The headphones have their own volume control. [ Dr. James Oct 29, 2017 ]
Yes just control the TV volume as normal. [ CHARLES R Oct 29, 2017 ]
Yes other viewers can still hear the t.v. while you use your headphones or you can mute the t.v. and just hear it through the headphones [ MIKE Oct 29, 2017 ]
Over-the-ear phones completely cover your ears so as to seal out external noise and also to prevent sound leakage from inside. On the other hand, on-the-ear phones are smaller and rest on your ears. [ Rosmadi Jan 06, 2017 ] Works for Sennheiser
