The Best Sennheiser Wireless Headphones for TV & Tips for Connect to TV

Over the years, we have reviewed a plethora of ‘TV-oriented’ wireless headphones from many makers. We keep coming back to the Sennheiser ‘RS’ line which we think offers some of the best products in this specialized category.

Using wireless headphones for TV has several nice benefits. Along with handy wire-free convenience and improved dialogue / speech intelligibility (more on that below), Sennheiser base transmitter stations can broadcast to two wireless headphones at the same time. So the ability for viewers to set the TV volume to their individual liking via their own headphone is a huge plus for keeping things copacetic around the household.

wireless headphones for TV

Your TV has either ‘ digital‘ or ‘ analog‘ audio output connections – sometimes both. This factor will determine which wireless headphones, cables or accessories you will need for your particular television.

For example, if your TV only has analog RCA-type connections (bottom inset; far left), it makes sense to choose an analog wireless model like the Sennheiser RS 135 since you won’t be making use of upscale digital connection features – meaning you’ll save yourself a ton of dough!

How To Connect Wireless Headphones To Your TV

Wireless TV headphones contain a miniaturized receiver that communicates with the headphone base station.

The base station directly connects to your TV via either an analog cable or digital cable method, depending on your particular television. Some flat screen TVs may only offer digital audio output capability.

Digital connection methods are either via an optical or a coaxial cable (shown top inset, right panel).

Analog connection methods are either via RCA stereo [dual] plugs or from the 3.5 mm headphone jack and/or the ‘mini’ line-out jack (shown top inset, left panel).

Whether connected via either digital or the analog RCA method, the internal TV speakers will remain adjustable via the normal TV volume control, while the headphone listener will use the independent volume control on the headphones.

Although the sound quality won’t be as good as via digital connection methods, you can plug the base station directly into the headphone jack (1/8″ or 3.5 mm mini-plug) on your TV. This plug type will often have a little headphone image above it (see top inset; left panel). This method is always an  analog connection that will turn the TV speakers OFF.

Some older televisions may not have any other audio connection method. In this situation, the headphone plug connection might be the only way to use wireless headphones with that type of TV.

Best Dialogue Intelligibility Using Wireless TV Headphones

An important aspect of high-quality TV and movie watching is speech intelligibility. In other words, how clearly you can hear and understand dialogue between the characters and during narrative voice-overs.

One major benefit of wireless TV headphones is that many of these models are optimized for the best speech intelligibility possible.

For example, the frequency range that determines audible differences between human “S” and “F” vocal sounds occurs between 3,000 kHz and 7,000 kHz. This is often called the ‘vocal presence’ region. Many built-in TV speakers – especially flat panel TVs –  have lousy fidelity in this frequency range. And turning up the volume simply increases distortion modulation and mid-frequency harmonics, further smearing the dialogue.

Top wireless TV headphones are able to provide improved fidelity in these important speech frequencies. They also allow others in the room to listen at a regular volume via the TV speakers if so desired.

Considering Non-Wireless and/or Standard ‘Wired’ Headphones for TV

Of course, you can use any standard ‘wired’ set of headphones if your TV has a built-in headphone jack, although perhaps a headphone extension cord may be needed. On most TVs with a headphone jack, directly connecting headphones automatically turns off the TV speakers and you’ll be able to adjust the headphone volume with the volume control for the TV set itself.
