DAC Capabilities

For your information, Qudelix 5K relies on ESS ES9218P Digital-to-Analog Converter to change the audio format of incoming signals. The DAC is famous for its high performance as well as its ability to generate high-quality audio. Noteworthily, it’s capable of enhancing computer-based audio when used as a USB DAC. Unsurprisingly, Qudelix 5K is held in high esteem by audiophiles around the globe.  

About BTR5, it comes alongside dual AK4377A DAC chips which make it a powerful conversion platform. Since the dual setup improves dynamic range as well as separation of audio elements, all elements will come out more clearly.

Output Power

Qudelix 5K offers 47mW at 30 ohms for unbalanced power and 157 mW at 32 ohms for balanced output. The amount of power means there is excellent control over the sound which results in optimal audio and volume. BTR5 is superior to Qublix 5K in terms of power though as it can deliver 80 mW for unbalanced output and 240 mW for balanced output at 32 ohms. The gap in power permits BTR5 to support more devices and produce clearer dynamic sounds than Qudelix 5K.

Battery Life

The battery life of Qudelix 5K lasts between 10 and 12 hours so it’s convenient to use. If you go on long trips every now and then, you won’t regret investing in  Qudelix 5K.

Automated Battery Care

Qudelix 5K contains programs that manage its battery in use and outside of use for the best longevity. It’s going to draw power directly from USB when in USB DAC mode so it won’t draw power from the battery when charging. That leads to long battery life as well as a high level of flexibility. 



The user interface of BTR5 is easy to use and simple to manipulate: it consists of 3 buttons and a mic for hands-free calls. Aside from that, the small button that lies between the volume and power buttons is multifunctional.

Finally, BTR5 features memorized volumes with 60 options and 32 options for USB and Bluetooth respectively so nailing the volume is a walk in the park. 

FiiO Music App

Noteworthily, if you opt for BTR5, you may use the FiiO music app to access more options such as filters, channel balance and a 10-band equalizer. While the MQA decoding feature reduces the filters from 6 to 2, it doesn’t significantly affect the experience as a whole. The app comes in handy when you want to use BTR5 while doing something else, especially if you are driving.

Screen Display

BTR5 incorporates a 0.49-inch OLED screen that shows you all the key information: battery life, pairing status, call status, volume, and Bluetooth codecs. In use, the screen of BTR5  will help you change between modes like car and charging at a moment’s notice. 


All in all, Qudelix 5K and BTR5 have unique characteristics that permit them to excel in distinct situations.
