EarStudio ES100-24bit Portable High-Resolution Bluetooth Receiver/USB DAC/Headphone Amp with LDAC, aptX HD, aptX, AAC (3.5mm Unbalanced & 2.5mm Balanced Output)

Model: ES100   |    Mpn: ES100   |    Ean: 4571314562127   |    PartNumber: ES100   |   Asin: B078H4YD2L

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 200~600-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.

Features

  • 24bit Bluetooth receiver designed to deliver studio-quality sound through your ears WIRELESS - using your existing wired headphones, earphones or even speakers.
  • Dimension 1 x 2 x 0.5 inch / Weight 20g / 14 hours of continuous playback / Dedicated app featured with 10 band EQ and Ambient mode / USB audio playback / device firmware update
  • Including 2 independent Hi-fi DACs and Amplifiers (Asahi Kasei AK4375a) - the optimal Dual DACs/AMP design for both single-ended and full-differential outputs
  • Analog volume control allows to keep the optimal audio performance even at low volume level using Programmable Gain Amplifier (PGA) which is known for the best way to control the volume/ Built-in microphone supports answering calls while using earphones without a microphone
  • Max. Output Power (No load): 1.1Vrms (3.2V peak-to-peak) at 3.5mm unbalanced output/ 2.2Vrms (6.4V peak-to-peak) at 2.5mm balanced output [Output Impedance: Approximately 1-ohm]

From the get go, all of us were instant fans of the AudioQuest DragonFly USB DAC, and the way it improved the sound of our computer music. While the original DragonFly defined the market for micro-DACs, its USB power draw made it compatible with computers only. But a lot of us music lovers have wished and craved a more portable version one that could be reliably used and work with Apple and Android smartphones and tablets. Well, we got our wish. The DragonFly Black now delivers that same clear, dynamic sound with Apple or Android mobile devices. Convenience and performance are no longer mutually exclusive. With DragonFly Black, any computer, laptop, tablet, or smartphone can be used as a true high-fidelity music player, allowing music lovers to enjoy beautiful sound wherever they go, whenever they please.

The DragonFly Black is the best ever value AudioQuest DAC. The new price point makes it more affordable than ever and the ideal accompaniment for your smartphone or tablet. Despite the price drop, the sound quality has been improved by fitting a high-spec ESS 9010 DAC (Digital to Analogue Converter).

With lower power consumption than before, the Dragonfly Black is now suitable for use with smartphones and tablets without undue battery use.

Whether you listen to music on your smartphone, tablet, Mac, PC or laptop, the audio quality can easily be improved. Whether you use headphones or have your device connected dir ... ... ... AudioQuest and DragonFly designer Gordon Rankin worked alongside Microchip Technology to develop a new high-performance, full-speed USB microcontroller solution that delivers improved signal-to-noise ratio and significantly lower power consumption. Drawing 77% less current than the previous microcontroller, the new Microchip PIC32MX microcontroller enables true compatibility with Apple iPod/iPhone/iPad and Android smartphones/tablets. At the heart of DragonFly Black is a 32-bit ESS Sabre 9010 DAC that uses a sophisticated minimum-phase digital filter to provide more naturally detailed and dynamic music. This high-performance DAC is typically found in today's higher-end CD and Blu-ray players. DragonFly Black will accept almost any audio you want to play on your computer and make it sound dramatically better, whether your listening pleasure is iTunes or streaming music services such as Pandora, Spotify, Amazon, or Tidal. Despite its tiny size, the Dragonfly will play a wide variety of music files. Twin clocks ensure perfect playback of 44.1 kHz (CD quality), 48 kHz, 88.2 kHz and 96 kHz. As a final neat touch, the dragonfly logo glows various colours to indicate the file frequency: green for CD (44.1 kHz), blue for 48 kHz, amber for 88.2 kHz and magenta for 96 kHz.
