The Beauty of Versatile PLENUE

The PLENUE R is an all-round player with versatility that excels in a variety of areas,
featuring super-HD sound, aptX Bluetooth codec support, 2.5 mm balanced output,
17 hours of continuous playback, and LEDs that change depending on the sound source.
Feel the difference in perfectly-reproduced HD with the PLENUE R,
the next evolution in the PLENUE line.

The World's Finest 24bit/192kHz Stereo DAC,

The PLENUE R is equipped with the PCM5242 digital-to-analog converter (DAC), designed for high-end hi-fi audio systems, to deliver superb quality sound. It features Texas Instruments' latest hyper-advanced current-segment architecture and superior DirectPath conversion performance to faithfully reproduce not only 24bit, 192 kHz PCM sources, but high-definition resolution DSD and DXD sources as well.

High-Performance SoundPlus Amplifier for Sound Perfection

One requirement for achieving perfect sound is a high-performance amplifier that is optimally compatible with high-end receivers. Texas Instruments' high-performance SoundPlus amplifier delivers high voltage while maintaining the highest level of linearity—a significant step up in audio technologies from existing versions of amplifiers. The amplifier generates powerful performance capable of driving high-end headphones with high impedance without the need for a separate headphone amplifier. Now, sophisticated and precise sound tuning makes it possible to clearly express any frequency range in combination with a variety of receivers.

High Quality Clear Sound
Balanced Output

Balanced output effectively blocks noise generated when signals are transmitted by adding 'out of phase' signals to unbalanced output signals. Since it transmits two types of signals simultaneously, the PLENUE R strengthens the output signal for clearer and crisper reproduction of original sound. The PLENUE R uses balanced output to reproduce crisp original sounds.

High Quality Bluetooth Audio Codec
Qualcomm® aptX™ audio

The PLENUE R supports aptX, a high-quality audio codec that provides higher compression efficiency and superior sound quality compared to conventional SBC codec Bluetooth transmission. You can now enjoy PLENUE R through any earphones, headphones, or speakers that support Bluetooth, and the application of
JetEffect 7's powerful acoustic field via Bluetooth output means
you can savor rich sound quality with greater variety.

Beyond the Limits of Hearing
Premium Sound DAC Filter

Four digital filters (Normal, Low Latency, High Attenuation, Asymmetric FIR) are provided to enable fine micro-tuning and allow implementation of transient signal responses in the time domain. This empowers listeners to tune sounds previously beyond the limits of hearing even with identical sound sources.

Long Playback Hours
Music Playback 17 hours

Thanks to a low-power circuit design and high-efficiency battery, the PLENUE R delivers 17 hours of continuous MP3 (128 kbps) playback and up to 16 hours of HD FLAC (24bit, 96 kHz) playback.

Unparalleled Acoustic Performance

The PLENUE R's high-definition sound is realized through 123 dB of SNR, 0.001% of THD+N, and -134 dB of crosstalk, essential figures that represent the performance of acoustic equipment.


SNR (Signal to Noise Ratio)

SNR, or signal-to-noise ratio, is a measurement for indicating how much noise is mixed into an audio signal. A high SNR value means a clearer, noise-free original studio sound.


Stereo Crosstalk

Stereo crosstalk indicates the degree of interference between left and right channels caused by electromagnetic induction. A low stereo crosstalk value means less inter-channel interference for a clear separation of left and right channels.


THD+N (Total Harmonic Distortion+Noise)

THD+N is an indicator of signal distortion caused by various factors, including harmonics. A small THD+N value means a reduced occurrence of harmonic distortion on an audio device.


Jitter is a measure of clock signal fluctuation due to temperature or other electrical effects. Lower the Jitter values, less the influence to the clock signal via internal or external environments.

High SNR, Indispensable Element for HD Sound

When we hear the music, acoustic signal picks up unavoidable noises as the signal processes to the output, the process leads to distortion in the original signal. This phenomenon can be expressed as a numerical value of SNR (Signal to Noise Ratio). SNR compares the level of a desired signal to the level of background noise. It is one of key criteria that can be measured to compare acoustic performances between one to another. If there is a difference of 6dB between two devices, there is a difference of 1 quantization bit in digital signal. For example, the device with 113dB has a loss of more than 1 quantization bit in digital signal, which leads to twice the amplitude resolution difference comparing to PLENUE R with 123dB. Therefore, to fully enjoy the HD Sound, a device must have excellent SNR figures. Having a poor SNR or THD means the device performs imperfect reproduction of the 24bit source, so there is no difference between playing 24bit source and 16bit source. COWON processed through intensive research and development period to achieve the best SNR, THD etc. PLENUE R covers from basic specifications to advanced ones offering enhanced enjoyment of listening HD Sound to users.


Tuning the Physical Limits of Space-Time
JetEffect 7 & BBE+

Speakers, headphones, and earphones tend to delay the high-frequency band more than the low-frequency band, even in original sound sources. When facing these phenomena, JetEffect 7 and BBE+ compensate the physical phase to reproduce vivid original sounds like a live performance and provide optimal HD sound via sophisticated methods and controls.

Sound Source LED Indicator Changing its Color According to Sound Source

Normal Sound HD Sound DSD / DXD

Three LED colors shows up depending on sound sources during playback, whether normal, HD, or DSD/DXD. The colorful source-based LEDs enhance your listening pleasure.

Adapted High Precision TCXO
for Reliable HD Sound

Sampling rate can be fluctuated depending on the temperature and environments of device. To minimize the difference in sampling, TCXO (Temperature Compensated Crystal Oscillator) is adapted. Having exceptional Phase Jitter of 1.0ps, PLENUE R can perform flawlessly in any circumstances.
