Question 1

Can I use the Sennheiser RS 255 with my regular Bluetooth phone or tablet?

Accepted Answer

Yes, absolutely! While the included transmitter is the key to its low-latency TV performance, the headphones themselves are standard Bluetooth 5.4. You can pair them directly with your smartphone, tablet, or laptop to listen to music or take calls just like any other Bluetooth headphone.

Question 2

How does the Auracast™ broadcast feature work with non-Sennheiser headphones?

Accepted Answer

Auracast™ is a new Bluetooth standard, not a Sennheiser proprietary technology. This means the RS 255 transmitter can broadcast to any other Auracast™-enabled headphones or earbuds from any brand, as long as they support the feature. It's designed for open compatibility.

Question 3

Is the battery in the Sennheiser RS 255 replaceable?

Accepted Answer

Yes, one of the great long-term value features of the RS 255 is that the rechargeable battery is user-replaceable. This means that years down the line, you can swap in a new battery instead of having to replace the entire headphone set.

Question 4

Will these headphones work with my TV if it doesn't have an optical audio output?

Accepted Answer

Yes. The transmitter includes both an optical (TOSLINK) input and a standard 3.5mm analog audio input. As long as your TV has either an optical port or a headphone jack, you'll be able to connect it. The 3.5mm option ensures it works with almost any TV, even older models.

Question 5

Does the Sennheiser RS 255 have Active Noise Cancellation (ANC)?

Accepted Answer

No, the RS 255 does not feature Active Noise Cancellation. However, its over-ear, closed-back design provides excellent passive noise isolation. The cushioned ear cups do a very good job of sealing out a reasonable amount of ambient noise, like the hum of a fan or air conditioner, allowing you to focus on what you're watching.

Question 6

What is the difference between the Sennheiser RS 255 and the RS 275?

Accepted Answer

The Sennheiser RS 255 and RS 275 use identical headphones (HDR 275) and the same BTA1 transmitter. The only difference is that the RS 275 bundle includes a headphone stand and is sold through Sennheiser's website and authorized dealers, while the RS 255 is a retail-exclusive (Amazon, in-store retailers) sold at $279.95, which is $20 less than the RS 275's $299.95.

Question 7

Does the Sennheiser RS 255 work with any TV?

Accepted Answer

Yes. The included BTA1 transmitter connects via HDMI ARC, optical/TOS-Link, or 3.5mm analog, which covers virtually all modern and older televisions. If your TV has any of these audio outputs, the RS 255 will work with it.

Question 8

Can multiple people listen to the RS 255 at the same time?

Accepted Answer

Absolutely. Thanks to Auracast technology, an unlimited number of Auracast-compatible headphones or earbuds can connect to the BTA1 transmitter simultaneously. Each listener gets their own independent volume and sound settings.

Question 9

Is the Sennheiser RS 255 good for seniors or people with hearing difficulties?

Accepted Answer

The RS 255 is an excellent choice. The Speech Clarity feature selectively amplifies human voices to make dialogue more intelligible, the controls are large and easy to use by touch, volume reaches up to 106 dB, and the Smart Control Plus app includes hearing profile customization. It's genuinely one of the best TV headphone options for those who struggle with dialogue clarity.

Question 10

How long does the RS 255 battery actually last, and can it be replaced?

Accepted Answer

Sennheiser rates the HDR 275 battery at up to 50 hours per charge — an industry-leading figure for wireless TV headphones. The battery is also user-replaceable, with Sennheiser estimating an average battery lifespan of up to 12 years. When the battery eventually degrades, you can replace it without buying a whole new headphone.
