Description:

EarStudio supports Qualcomm's aptX HD codec, which allows you to stream 24bit hi-res music wireless. EarStudio automatically enhances 16bit music into 24bit sound. We use CSR 8675 Qualcomm Chip and 2x DACs of AK4375a.


Noise free, jitter free.

EarStudio ES100 reproduces sound over Bluetooth through Radsone's patented DCT technology which reduces subtle digital noise and cleans the jitter from Bluetooth streaming.

Dual DACs with analog volume control

EarStudio has optimized circuit architecture, proprietary DualDrive technology, using 2 independent Hi-Fi DACs and Amplifiers. Unlike other dual DAC audio systems, the fully differential audio signal path directly goes to the output jack, with NO switch components in the way, delivering pure signal without any loss or distortion, and with enough power. Moreover, 2 selectable operating modes support 2x current or 2x voltage, as needed by depending on the type of connected headphones. Then, we took a further step for details by adopting an analog volume control. Digital volume adjustment has the downside because it scales down PCM audio sample before the D/A conversion, resulting in harsh sound and the loss in sound detail, SNR, as well as THD. EarStudio offers analog volume control to keep the optimal audio performance even at low volume level using Programmable Gain Amplifier (PGA) which is the best way to control the volume.

Full Balanced and single ended output

EarStudio offers two outputs: A single-ended/double current 3.5mm jack and full-balanced/double voltage 2.5mm Jack.

Note: For headphones with the high impedance over 200600-ohm, ES100 may not be able to deliver enough sound pressure level, especially with 3.5mm unbalanced output. Please note the maximum output power level of ES100 for your high impedance head units.
