General Description
The RS 160 combines the best wireless audio quality with a truly versatile compact transmitter for listening at home, on-the-go or at the office.
This wireless headphone system consists of a pair of wireless headphones (HDR 160) and a compact transmitter (TX 160) which runs on AC or battery power to best accommodate your application. The transmitter's compact size makes it a natural selection for automotive installs or in dentist/doctor's offices. The RS 160 utilizes KLEER's uncompressed digital wireless audio transmission (it sounds wired!), offering a range of up to 60 feet, audiophile-grade sound and reception to four optional pairs of Sennheiser KLEER headphones. Never fuss with tuning again thanks to automatic, interference-free pairing between the headphone and transmitter.
The headphones' leatherette earpads and headband cushions provide outstanding comfort while their closed, around-the-ear design prevents sound leakage.
This headphone has it all.
Features
- KLEER uncompressed audio transmission for interference free reception
- Audiophile-level transducer systems with powerful neodymium magnets for clear and detailed audio reproduction
- Compact, portable transmitter - also runs on battery power
- Multi-receiver mode- Up to 4 Sennheiser KLEER headphones listening to the same source
- Digital volume control with mute function
- Leatherette earpads and headband cushions for outstanding comfort
- No complex set-up required – Just plug into the analog audio outputs on your audio source!
- KLEER technology will not interfere with wireless networks or other 2.4 gHz devices
- 2 year warranty
- *note* while the sound quality of these headphones is fantastic for any type of music, they were not designed for use while recording/tracking and monitoring or musical instrument practice (performer wears the headphones while playing).

Glossary
| Audio input |
| Specifies the type of plug mounted for an audio input. |
| Cable length |
| The cable length is usually measured between the anti-kink sleeves of the cable (cable length without connectors). |
| Charging time |
| The time required to recharge a Sennheiser accupack. After recharging, automatic chargers will automatically switch to trickle charging. |
| Ear coupling |
| A distinction is made between headphones which are worn on the external ear (supra-aural) and those which surround the ear (circumaural). Open headphones have foam ear pads that rest on the ears or ring pads that surround the ears. Closed headphones, on the other hand, nearly always have circumaural ear pads. |
| Frequency response (headphones) |
| The frequency response of a pair of headphones is given within limits defined by the manufacturer. |
| Impedance |
| Impedance expresses the AC resistance of a microphone or a set of headphones. It is dependent on frequency and is given at 1 kHz as the so-called nominal impedance. Impedance is measured in ohms. In recent years, an industrial standard has developed, setting the impedance of headphones at 50 or 600 ohms. Sennheiser headphones are manufactured according to this standard, thus practically ruling out connection problems. With microphones, the input impedance of the following microphone amplifier should have at least three times the value of the nominal impedance, in order to prevent it from unnecessarily attenuating the microphone signal. |
| Modulation |
| The process in which one wave is varied by some parameter of another wave, for example, an RF carrier frequency that is modulated by an audio signal. Types of modulation include amplitude modulation, frequency modulation, pulse code modulation and pulse width modulation. |
| Operating time |
| States how long a unit can be continuously used with one set of batteries / rechargeable accupack. |
| Range |
| See RF wireless headphones, transmission loss. |
| Sound pressure level (SPL) |
| Due to the impractical numerical values, the sound pressure is usually given as the logarithmic value of the sound pressure level according to the equation: dB SPL = 20 x log (po / 0.00002 Pa). The abbreviation SPL (sound pressure level) is added in order to make a clear distinction from other uses of dB. The reference sound pressure, which is at the same time the threshold of hearing, is then 0 dB SPL. The threshold of pain is 140 dB SPL. A difference in the sound pressure level of 1 dB is just about perceptible, while a doubling of the sound pressure corresponds to 6 dB and a doubling of the volume corresponds to a rise of 10 dB.

| Total harmonic distortion (THD) |
| Total harmonic distortion is a measure of non-linear harmonic distortion and is given in %. Non-linear harmonic distortions are signals which were not present in the original before the signal was converted by the headphones. These unwanted signals are caused by the diaphragm, whose movements do not precisely move in time with the electric signals that cause it to move. Unfortunately, this is a feature of all electroacoustic transducers. Although it cannot be completely eliminated, suitable steps can be taken to minimise it. However, the user is not interested in why this distortion takes place but in how great the level of distortion must be for it to become perceptible. According to the findings of several research projects, a total harmonic distortion of 1% in the frequency range of 100 to 2000 Hz is imperceptible. Below 100 Hz, the perceptibility threshold lies at 10%. |
| Transducer principle |
| Two transducer principles have become established for the conversion of electric energy into mechanical energy: electrodynamic and electrostatic transducers, whereby the latter is only to be found in audiophile systems, due to their relatively high manufacturing costs. Electrodynamic transducers basically consist of a ring-shaped permanent magnet and an oscillation coil, which is fixed to the receiver diaphragm. When an audio-frequency alternating current is passed through the oscillation coil, it is caused to vibrate in accordance with the audio-frequency alternating current, thus causing the diaphragm to vibrate in the same way. |
