What are the advantages of wireless TV headphone systems?
With a wireless TV headphone system, you benefit from the following advantages:
- You can watch TV while your partner can e.g. read or sleep undisturbed in the same room.
- You can enjoy crystal-clear sound with your favorite headphones.
- Your hearing sensitivity starts to change but you can enjoy perfect TV sound without having to increase the volume.
- You can better understand and enjoy the dialogs in movies or sportscasts, without annoying background noise such as background music or stadium noise.
- You can use your wired headphones, but also move around freely in the room.
Which headphones can be used with the clip-on receiver?
The clip-on receiver can be used with all headphones with a 3.5 mm jack plug and a minimum impedance of 16 ohms (e.g. Sennheiser HD 569 or HD 4.20s headphones).
Which of the digital wireless headphone systems is best for me?
Which country adapters are supplied with the wireless headphone system?
The wireless headphone system is supplied complete with a power supply unit with plug adapters for Europe, the UK, the USA and Australia.
How do I best connect the transmitter to my audio device?
You can connect the TR 5000 transmitter to your audio device using either a digital (optical) or an analog connection. The connections for audio devices are usually labeled "AUDIO OUT" or "DIGITAL OUT". We recommend using the digital connection.
If you connect an audio source to both inputs (digital and analog), only the analog audio source will be reproduced.
The optical digital cable and the stereo audio cable with 3.5 mm jack plugs are supplied with the Flex 5000. Additional accessories and adapters (e.g. SCART or RCA adapters) are available from your Sennheiser partner.
Which input formats are supported by the digital optical audio input?
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.
I have several wireless devices at home (e.g. WiFi router, cordless telephone). Will they interfere with my wireless headphone system?
The wireless headphone system uses automatic frequency management to ensure the best possible radio transmission for the Flex 5000 and optimum co-existence with other wireless devices within its vicinity.
Can I use several wireless headphone systems in close proximity?
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 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 TR 5000 transmitter?
You can simultaneously use up to 4 paired RR Flex clip-on receivers, RR 5000 or RR 2000 stethoset receivers, or HDR 165, HDR 175 and HDR 185 headphones with the TR 5000 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 5000 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 5000 transmitter.
What are the advantages of lithium-ion polymer rechargeable batteries?
- 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.
The 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.
The lithium-ion polymer rechargeable battery is automatically charged when you place your device into the transmitter's charging compartment. The built-in lithium-ion polymer rechargeable battery must not be replaced or removed because it has a longer operating time and service life. In addition, your device features a charging reminder function.
If the operating time of the rechargeable battery decreasesdrastically, have the rechargeable battery replaced by your Sennheiser service partner.
- If 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.
Why are my TV's internal loudspeakers muted when I connect the wireless headphone system using the analog cable?
This should only be the case if the TR 5000 transmitter is connected to the analog headphone socket of your TV. Some TV models mute the internal loudspeakers as soon as a headphone jack is inserted. Check the menu of your TV to see if and how the internal loudspeakers can be unmuted. Alternatively, you can connect the transmitter using the audio connection "AUDIO OUT" or "DIGITAL OUT" (if available).
Can I use several headphones/receivers with one transmitter?
You can connect (pair) up to 4 receivers to the TR 5000 transmitter and use them simultaneously.
How can I personalize the sound of the wireless headphone system?
The hearing profiles allow you to personalize the sound of the Flex 5000 and to especially improve the speech intelligibility. You can choose between the following hearing profiles:
Hearing profile 1 - Low-frequency tones are slightly boosted to provide a warm, full sound. High-frequency tones are reproduced less piercing and clanking.
Hearing profile 2 - High-frequency tones are strongly boosted to provide a crystal-clear sound, especially for sibilants and high-frequency tones such as twittering of birds.
Hearing profile 3 - Low-frequency tones are attenuated so that they cannot mask high-frequency tones.
If no hearing profile is selected, the sound from the connected audio source is reproduced unchanged.
When speech is mixed with annoying background noise, you can use the speech intelligibility function. The speech intelligibility function automatically detects and reduces annoying background noise. Speech is foregrounded and easier to understand. Press the Speech intelligibility button to activate or deactivate the function. The speech intelligibility function can also be used in addition to one of the hearing profiles 1-3. If you switch to the next hearing profile, the speech intelligibility function is automatically deactivated.
Why is there reverb/echo when using the headphones with my TV?
When using the headphones with your TV and the TV sound is also reproduced through the TV’s internal loudspeakers, this can cause reverb/echo issues. To eliminate the reverb/echo effect, reduce the volume on your TV or check the audio output settings of your TV to see if you can reduce the "latency" or "delay" setting (recommended setting: "0" or "low").
What can I do if the volume is very low?
This should only be the case if the wireless headphone system is connected to an analog headphone socket of your TV/audio device. In this case, make sure that the volume of your TV/audio device or the volume of the headphone socket on your TV/audio device is adjusted to at least a medium level. Deactivate the muting function on the audio source.
Are there special instructions for battery maintenance?
No, the transmitter’s intelligent battery charging technology ensures that the rechargeable batteries are always charged to their optimum capacity and the battery life span is maximized. Make sure to only charge the rechargeable battery within the permissible temperature range of 5 to 40 °C/41 to 104 °F. If you plan to store away the RR Flex receiver for extended periods of time, make sure that the rechargeable battery is about half charged.
How can I protect my settings against accidental changes?
The advanced settings allow you to adjust the TV headphone system to your individual needs and to protect the settings against accidental changes.
What does a flashing battery status display on the transmitter mean when I switch the stethoset receiver off?
A flashing battery status display means that the charging reminder function is activated. When you take the stethoset receiver out of the transmitter's charging compartment and the transmitter switches to standby mode, the Battery LED will flash for 10 minutes to remind you to charge the stethoset receiver. The LED stops flashing when the charging process starts. You can also deactivate the charging reminder function.
