The Qudelix 5K Plus is a compact Bluetooth DAC and headphone amplifier that combines wireless playback, USB audio, and flexible sound customization in a single device. It is based on the Qualcomm QCC5181 Bluetooth chipset and supports Qualcomm Snapdragon Sound V2. Conversion is handled by two ES9219 SABRE Hi-Fi DACs, clocked by a high-precision MEMS audio clock.


Bluetooth and Codecs

The 5K Plus operates with Bluetooth 6.2 in the 2.4 GHz frequency band (Class 2, 2.5 mW / 4 dBm, up to 10 m). Thanks to the highly sensitive 3D LDS (Laser Direct Structuring) antenna, the Bluetooth connection extends beyond 10 m.

Supported codecs include aptX Lossless, aptX Adaptive, aptX HD, aptX Low Latency, aptX, LDAC, AAC, and SBC, allowing the device to adapt to smartphones and media players from various manufacturers.


DAC and Headphone Outputs

Two ES9219 SABRE Hi-Fi DACs handle the digital-to-analog conversion. Two outputs are available: a balanced 4.4 mm output with a maximum of 4.0 V RMS or 240 mW per channel, and an unbalanced 3.5 mm output with a maximum of 2.0 V RMS or 150 mW per channel.


USB DAC

As a high-resolution USB DAC, the 5K Plus processes signals up to 96 kHz / 24-bit (USB Audio Class 1.0). No separate driver installation is required on Windows, macOS, or Linux. Android devices can be connected via a USB-C to USB-C cable or an OTG cable. The USB-C port serves both for charging and data transfer.


Equalizer

The 5K Plus offers a 30-band GEQ/PEQ with double precision. Additionally, a 20-band GEQ/PEQ is available, allowing the left and right channels to be adjusted independently of each other. This allows the sound to be precisely tailored to your headphones, listening habits, and preferences.


Phone Calls

For calls, the 5K Plus is equipped with a highly sensitive MEMS microphone and Qualcomm cVc noise cancellation.


Operation and Display

The device features five multifunction buttons (Power, VOL+, VOL-, NEXT, PREV), a 0.96-inch OLED display (white, 128 × 64 pixels), and three-color LEDs on both sides.

To turn on the device, briefly press the Power button. The battery indicator initially appears on the display and disappears after 2 seconds. If you briefly press the Power button a second time while this indicator is visible, the 5K Plus starts up. Alternatively, you can turn on the device by holding down the Power button for more than 3 seconds. To turn off the device, hold down the Power button for longer than 1 second.

Pressing the VOL- and PREV buttons simultaneously activates or deactivates the key lock. Use the VOL+ and NEXT buttons to switch between the main screen and the settings menu. All functions can also be conveniently controlled via the app.


App and Firmware

The device comes with the Qudelix app for iOS and Android. For Windows and macOS, there is the Qudelix Chrome app. It is recommended to install the app before first use. Firmware updates can be installed wirelessly.


Housing

The housing is made of black plastic with a scratch-resistant UV coating.
