  • 136dB
    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.
  • -148dB
    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.
  • 0.0004%
    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.

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 124dB has a loss of more than 2 quantization bit in digital signal, which leads to four times the amplitude resolution difference comparing to PLENUE R2 with 136dB. 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 R2 covers from basic specifications to advanced ones offering enhanced enjoyment of listening HD Sound to users.

Faithful to Original Sound
Support Native DSD up to DSD256 DSD(Direct Stream Digital) is a high quality Super Audio CD format that processes signals at 2.8224MHz per bit. The technology carries the maximum sound information possible to reproduce the delicate and crisp sound of analog. To realize the best possible sound quality, the PLENUE R2 reproduces DSD in Native method supports DSD256(Quad rate DSD), the highest frequency among all DSD formats. High Quality Balanced Out
Maximum Output of 4.0Vrms 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 R2 strengthens the output signal for clearer and crisper reproduction of original sound. The PLENUE R2 uses 2.5mm balanced output to reproduce crisp original sounds.
High Quality Bluetooth Audio Codec
Qualcomm® aptX™ audio The PLENUE R2 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 R2 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.

AI Functionality for a Smarter PLENUE R2 To make your listening experience more comfortable and convenient, PLENUE R2 had to be smarter. High-Performance MasterHIFI Amplifier for
Sound Perfection One requirement for achieving perfect sound is a high-performance amplifier that is optimally compatible with high-end receivers. High-performance MasterHIFI 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.
  • Some songs' volume is too high or low. AI function handles these situations with ease. AI Volume continuously normalizes volume levels of sound files played more than once. You no longer have to adjust the volume of each of your songs.

    * AI Volume normalizes volume levels
     based on Normal Preset.
  • AI shuffle conveniently changes the playback order of songs. It even analyzes and arranges playlist positions according to your preferences.
  • AI JetEffect function, COWON's sound field technology "JetEffect" automatically matches presets that are best suited to each source file. PLENUE R2's AI functions automatically adjust the settings so your favorite tunes are played exactly the way you like them.
Beyond the Limits of Hearing
Premium Sound DAC Filter Five digital filters are provided to enable fine micro-tuning.
This empowers listeners to tune sounds previously beyond the limits of hearing even with identical sound sources.
Extensive Codec Support
from 32bit/384kHz HD Sound to DXD and DSD256 The PLENUE R2 supports a variety of audio formats, from 32bit/384kHz lossless/uncompressed AIFF to lossless/compressed formats such as FLAC, ALAC, and APE, as well as other popular formats including WAV, MP3, WMA, and OGG. Also, the device supports DXD(352.8/384kHz) and Native DSD256(11.2MHz) format to offer wide range of high quality sound formats.
20 Hours of Music Nonstop Playback Thanks to a low-power circuit design and high-efficiency battery, the PLENUE R2 delivers 20 hours of continuous MP3 playback and up to 18.5 hours of HD FLAC playback.
Sound Source LED Indicator
Changing its Color According
to Sound Source 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 R2 can perform flawlessly in any circumstances. Optimal Digital Path for
32bit, 384kHz via Independent CPLD We developed an optimized digital path circuit that supports 32bit, 384kHz sound sources and equipped the PLENUE R2 with an independent CPLD(Complex Programmable Logic Device), which supports fast operations and minimizes noise by optimizing bus and group unit digital signal processing.
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.

World's Renown Professional Sound Control
JetEffect 7 The user presets and 50 reference presets allow adjustment of the 10 band EQ filter and BBE+ with phase correction so each user has precision tone control for live sound reproduction. No matter which environment you listen to music, the kind of receiver you use, or genre of music you prefer, JetEffect 7 delivers the best Hi-Fi sound quality.
The Best Choice for Original Live Sound Reproduction, BBE+ Sound includes a unique high frequency harmonics, and this unique harmonics pattern helps users to distinguish the each instrument. This high frequency harmonics reach our ears earlier than the normal frequency in live sound. Human brain recognizes earlier signal as more important signal, therefore high frequency harmonics is vital component in music. However, like speakers, headphones, and earphones, receivers tend to delay high frequency range rather than low frequency range, resulting in decrease in clarity and reality. Normally, equalizer or tone control is used to increase clarity and reality in sound, however this method cannot remove the delay of high frequency range to reproduce the natural sound. By applying BBE, phase characteristics of lower and middle frequency bands can be delayed comparing to high frequency band, resulting high frequency reaches human ears earlier than any other frequencies to make the same condition as live sound. Also, by gently expressing high and low frequency range, very dense and clear sound can be reproduced.
