Set 860

Our Set 860 assistive listening device delivers sound to users with changing hearing needs.

Crystal clear, enhanced sound

The Set 860 not only enables you to set the volume to your taste without bothering anyone, it also allows you to tailor the audio signal itself to your personal needs. 

As we get older, it becomes more difficult for our ears to pick up sounds and voices. But when we turn up the TV volume, we often disturb others – our partners, our neighbors. The Sennheiser Set 860 solves this dilemma. It not only enables you to set the volume to your taste without bothering anyone, it also allows you to tailor the audio signal itself to your personal needs. Thus, you may even find you can turn the volume down a bit and still enjoy your TV sound in new clarity and crispness.

Your + in TV sound experience

With the Sennheiser Set 860 you have your TV sound directly at your ear with no distraction coming in the way. 

Even more important: You are able to adjust your TV sound just the way you need it. You can choose between three different preset hearing profiles at the mere push of a button, optimizing speech or music to fit your hearing needs. You can shift the left/right volume balance to improve sound for a “weaker” ear. You can even switch from stereo to mono to get the full audio content in each ear. A unique treat is the Speech Intelligibility function, which reduces TV background noise while enhancing speech. You will see how much more fun it is watching TV when you can follow dialog effortlessly.

Your + in effortless listening

The Sennheiser Set 860 keeps things light and ensures a stable connection to the docking station within the range of up to 70 m (200 ft).


Its lightweight under-the-chin headset applies no pressure to the head, adjusts automatically as you put it on, and does not interfere with glasses or your hairstyle. Advanced wireless technology ensures a stable connection to the docking station within the range of up to 70 m (200 ft). So, you can go into the kitchen to get a drink while still listening to your TV program. No need to worry about the battery, either. It has a playing time of up to 18 hours from a single charge and thus will accompany you even through the longest TV sessions. The battery recharges automatically when you put the headset on the docking station.

Your + in comfort

sennheiser Set 860 wireless TV listening system

From the unboxing to the actual listening session, with the Sennheiser Set 860 you always know exactly what to do.


Setup is extremely fast and straightforward. Buttons are few, large and clearly marked. You will be able to handle the controls without even looking. Battery and connection status are indicated by easy to read LEDs. The Set 860 even switches on and off automatically, to prevent the battery running flat unintentionally.


Your+ in independence

With a wireless TV headphone system, you benefit from the following advantages:\nYou can watch TV while your partner can e.g. read or sleep undisturbed in the same room.\nYou can enjoy crystal-clear sound without being completely acoustically isolated from your environment.\nThe stethoset receiver does not encircle your ears like normal headphones. The ear pads don't fully cover your ear canals and allow ambient sound to pass so you are not acoustically isolated from your environment.\nYour hearing sensitivity starts to change but you can enjoy and hear TV sound clearly without having to increase the volume.\nYou can better understand and enjoy the dialogs in movies or sportscasts, without annoying background noise such as background music or stadium noise.\n

What are the advantages of wireless TV headphone systems?

With a stethoset receiver, you benefit from the following advantages:\nWireless audio transmission\nBetter sound quality without annoying background noise such as traffic or children playing\nStethoset receivers do not ""squash"" your hair and your hairstyle is preserved\nStethoset receivers are ideal for wearers of glasses. The eyeglasses-compatible design allows you to wear your glasses comfortably, without painful pressure marks\nLarge operating buttons facilitate daily use\n

What are the advantages of the Set stethoset receivers?

Always maintain a distance of at least 10 cm/3.94" between the headphone cap and cardiac pacemakers or implanted defibrillators (ICDs) since the product generates permanent magnetic fields. At a distance of 10 cm//3.94", the magnetic field strength is < 0,1 mT so that any interference should be excluded.

Can I use a stethoset receiver when I have a cardiac pacemakers or implanted defibrillator (ICD)?

The wireless headphone system is supplied complete with a power supply unit with plug adapters for Europe, the UK, the USA and Australia.

Which country adapters are supplied with the wireless headphone system?

You can connect the TR 860 transmitter either to a digital or an analog audio source (e.g. a TV). The connections for audio devices are usually labeled "AUDIO OUT" or "DIGITAL OUT". We recommend using the digital connection.

How do I best connect the transmitter to my audio device?

The optical digital cable and the stereo audio cable with 3.5 mm jack plugs are supplied with the Set 860. Additional accessories and adapters (e.g. SCART or RCA adapters) are available from your Sennheiser partner.

If you connect an audio source to both inputs (digital and analog), only the analog audio source will be reproduced?

The supplied cables have color-coded connectors to simplify installation. If you connect the color-coded connectors to the matching colored connection sockets, then your installation is correct and the device is ready for operation.

Why do the supplied cables have color-coded connectors?

The wireless headphone system supports “PCM” or “stereo” audio signals. Surround sound formats are not supported. If an audio device/TV is connected to the digital optical input of the transmitter, set the audio format of the connected device to “PCM” or “stereo” by using the sound menu of the device.

Which input formats are supported by the digital optical audio input?

The wireless headphone system uses automatic frequency management to ensure the best possible radio transmission for the Set 860 and optimum co-existence with other wireless devices within its vicinity.

I have several wireless devices at home (e.g. WiFi router, cordless telephone). Will they interfere with my wireless headphone system?

Yes, you can use several wireless headphone systems in parallel (minimum distance between two systems: 0.5 m). What matters is that the headphones/receiver and the transmitter are paired with each other and connected.

Can I use several wireless headphone systems in close proximity?

You can simultaneously use up to 4 paired RR 800 stethoset receivers, or HDR 165, HDR 175 and HDR 185 headphones with the TR 860 transmitter. Other Sennheiser wireless headphones (e.g. RS 11x series, RS 12x series, RS 160, RS 170, RS 180, RS 220) are not compatible with the TR 860 transmitter and cannot be used. Please note that the HDR 165, HDR 175 and HDR 185 headphones can only be used for audio reproduction. Additional functions are not available and the headphones cannot be charged using the TR 860 transmitter.

Can I use other Sennheiser wireless headphones (e.g. RS 165, RS 175, RS 185, RS 11x series, RS 12x series, RS 160, RS 170, RS 180, RS 220) together with the transmitter?

Among the lithium-ion battery family, lithium-ion polymer rechargeable batteries currently offer the best performance. Compared to older rechargeable battery types, lithium-ion polymer rechargeable batteries are lighter and have a higher energy density. Charging of lithium-ion polymer rechargeable batteries is simpler and more efficient.\nThe service life of lithium-ion polymer rechargeable batteries is first and foremost determined by the number of charge cycles. A charge cycle is commonly understood as the full discharge of a charged rechargeable battery with subsequent full recharge. Our lithium-ion polymer rechargeable batteries are designed to be cycled (discharged and recharged) at least 800 times before their capacity decreases significantly.\nThe lithium-ion polymer rechargeable battery is automatically charged when you place your device into the transmitter's docking station. The built-in lithium-ion polymer rechargeable battery must not be replaced or removed because it has a longer operating time and service life. If the operating time of the rechargeable battery decreases drastically, have the rechargeable battery replaced by your Sennheiser service partner.\nIf you have purchased an optional MCA 800 charging adapter, you can also charge the stethoset receiver using the charging adapter to extend its operating time. You can also use your device during charging.
