Overview: The Sennheiser Flex 5000 Digital Wireless TV
headphones enhance your TV watching experience by providing clear, intelligible
audio of your favorite programs. The Flex 5000 includes transmitter/charger (TR
5000), a clip-on wireless receiver (RR Flex), in-ear headphones, and digital and analog connecting cables.
RR Flex: The RR Flex clip-on wireless receiver has a 3.5mm
audio output for connecting the supplied MX 475 in-ear headphones, or your own
favorite headphones for listening to your audio source. The connected headphones
must have a minimum impedance of 16Ω. With a range of up to
100 feet, the receiver allows you to move around freely while you watch
TV. It has a built-in Lithium-Polymer rechargeable battery (3.7V, 350mAh)
with a typical operating time of up to 12 hours. The RR Flex features an on-board volume control and Speech
TR 5000: The TR 5000 transmitter fully charges
the RR Flex in approximately 3 hours. A 30-minute partial charge gives you 2
hours of operating time. You can connect an audio source,
such as your TV or home stereo, using the supplied optical digital (Toslink) or
analog cables (3.5mm). The included AC adapter has four interchangeable power
plug adapters (North America, Europe, Great Britain, and Australia), allowing
you to use the Flex 5000 system most anywhere in the world. The TR 5000 lets you
check the charging status of a docked receiver, as well as the remaining charge
of a paired receiver when it is turned on.
Settings: The Flex 5000 offers several settings for tailoring
your listening experience to your individual tastes or needs:
- Hearing Profiles: The hearing profiles change the sound
of the audio signal to improve speech intelligibility by using compression,
and boosting/attenuating certain frequencies. Using the keypad on the
transmitter, you can choose from the following profiles:
- Hearing Profile 1: Low frequency tones are slightly
boosted to provide a warm sound. High frequency sounds are reduced to
make them less piercing.
- Hearing Profile 2: High frequencies are strongly
boosted to give you a crystal-clear sound.
- Hearing Profile 3: Low frequencies are lowered to
prevent them from overpowering the high frequencies.
- Speech Intelligibility Function: The Speech
Intelligibility function automatically detects and reduces unwanted
background noise to make speech easier to understand. The Speech
Intelligibility button is located on the headset. A status LED on the
transmitter will glow blue when the function is activated. Speech
Intelligibility can be used in combination of any of the three Hearing
- Balance: You can adjust the left/right balance of the
headset using the L and R buttons on the transmitter.
Pairing Multiple Receivers: Up to four
receivers can be simultaneously paired to the transmitter. When more than one
receiver is paired, you can not adjust the balance, nor will the remaining
charge status and hearing profile be displayed on the transmitter.
