Product Information

Optical–Bluetooth–USB Digital-to-Analog Converter

The multiple award-winning AudioQuest DragonFlys just got a sibling -- the AudioQuest Beetle joins the Digital Critter family of small, highly affordable, and surprisingly potent devices that make even expensive headphones or whole systems sound a lot better.

By accepting not only USB audio, but also Toslink cable and Bluetooth wireless, the Beetle improves the sound of every way you enjoy music, movies, and video. Using the Beetle instead of the low-quality built in Digital-to-Analog-Converters (DACs) supplied with powered speakers, TVs, computers, phones, multiroom devices, etc., actually does what the old cliché says – the Beetle will bring your system to life.


  • MQA playback over USB enabled with forthcoming firmware update
  • 24/96 asynchronous-transfer USB means no external driver required
  • Operating firmware updatable with free AQ device manager app
  • Minimum-phase digital filter for natural, relaxed sound
  • Superior linear (Analog, Not Digital) power supply
  • Standard pairing procedure when using Bluetooth

 Toslink Optical Input

The Beetle’s Toslink optical input allows you to connect to the many devices whose analog outputs are not blessed by a Beetle-quality DAC, and to those, like many of today’s TVs, that don’t have an analog output at all. Televisions, media servers, and gaming consoles are just a few of many possible applications.

When there is a choice of digital outputs, the RF noise isolation provided by optical will often give a Toslink connection a tremendous advantage over a metal connection. However, please remember that Toslink cable quality varies just as widely as from the poorest to the very best USB, Coax, Ethernet, etc.

Bluetooth Receiver Using Asynchronous-Transfer

For Beetle, AudioQuest created the first asynchronous-transfer Bluetooth (Stream-length BT) receiver. When Beetle’s Bluetooth is used with smartphones, tablets, and other Bluetooth enabled devices, you will be amazed at how much better Bluetooth can be.

No, the bit rate still maxes out at 320K – but a properly received and rebuilt 320K audio stream can be astonishingly enjoyable and articulate. "Audiophile Bluetooth" is no longer an oxymoron.

Please note that Beetle only receives Bluetooth signals and does not transmit.

 Asynchronous-Transfer USB

The Beetle could have one of those “DragonFly Inside” type labels since the Beetle uses the same Streamlength Asynchronous USB software and many of the same parts as AudioQuest’s remarkable DragonFly USB DACs.

The Beetle’s Micro-B input accepts USB digital audio from mobile devices, computers, network attached servers, etc., providing clearer, cleaner, more immersive sound to headphones, powered speakers, or audio components.

I have the sound bar 500 with the module 500 base. My friend had five analogy speakers. Can I tie those in to tv along with sound bar for souround sounds?
A shopper on Nov 24, 2020
  Thanks for your inquiry. Other than the optional Bose wireless surround speakers, the Sound Bar 500 has no provision to connect additional wired speakers.
