Audirect Beam 3 S MQA Portable USB DAC | Headphone Amp

Pure 4.4mm balanced headphone amplifier output

Audirect Beam 3S adopts the new generation of ESS Sabre HiFi series chip - ES9281AC PRO and a quartz oscillator. It boasts precise digital-to-analog conversion capabilities, supporting PCM specifications up to 32-bit/768kHz and native DSD512 decoding. It also has the MQA Renderer capability and can unfold the second and third layers of MQA files. The impressive specs of 118 dB signal-to-noise ratio and 0.0003% THD+N total harmonic distortion make it top-tier among its competitors.

Audirect Beam 3S further enhances the left and right channels with two separate OPAs for further amplification, improving the headphone amplifier's driving performance. The device's dimensions are incredibly slim at 53x15x11mm, yet it still provides an excellent 4.4mm balanced headphone amplifier output.

Three adjustable gain levels

The three-level adjustable gain design makes it easier to adapt to different headphones for effective driving, allowing users to set a suitable volume level. Low Gain is suitable for driving high-sensitivity in-ear headphones, while High Gain provides excellent drive capability for over-ear headphones.

Support for Apple and Android Phones and Computers

The Audirect Beam 3S is equipped with a USB-C input interface, compatible with Apple, Android phones, and computers.
