## Description

Product description What is Bluetooth DAC/AMP? Bluetooth DAC/AMP receives the digital audio over the Bluetooth link and performs Decoding, D/A Conversion, and Amplification with its hardware. Many use USB DAC for upgrading PC or Laptop Sound Quality. For smartphones, Bluetooth DAC can be the best option to upgrade Sound Quality. Although Bluetooth Audio Codecs are all lossy codecs, SONY LDAC, aptX-HD, and AAC provide good enough perceptual audio performance, enabling the built-in DAC/AMP reproduce the best Sound Quality. *The Qudelix-5K is a Bluetooth receiver designed to work with wired headphones or earphones. It does not function with Bluetooth headphones, since it is not a Bluetooth transmitter. Qualcomm QCC5124 - The new Qualcomm Low Power Bluetooth SoC QCC5100 series is designed for advanced Bluetooth application. The breakthrough SoC series is engineered to reduce power consumption by up to 65 percent for both voice calls and music streaming, compared to previous CSR8675 solution. It is designed to reduce power consumption dramatically and offers enhanced processing capabilities. Qudelix-5K is the world 1st Bluetooth DAC/AMP designed with QCC512x chipset. QCC512x's ultra-low power consumption and the most powerful DSP capability enable Qudelix-5K to maintain high bitrate Bluetooth streaming more secure and for a longer time. Embedded Pro-Grade Equalizer - 5K is the only Bluetooth DAC/AMP, which provides a pro-grade 64-bit double-precision parametric equalizer for every input source. It processes every incoming source audio from everywhere: Youtube, Apple Music, Spotify, iOS, Android, PC, Bluetooth(all Codecs), and USB. It provides accurate and precise filtering performance, keeping original sound quality and resolution. Qudelix is an audio system engineering company. We deliver a portable and affordable high-end audio solution for everyone. Based on our R & D team's highly extensive background and experience, we design and implement the cost-effective high-end audio system. System-on-Chip (SoC) is one of the most important keys to the best digital audio system. We always keep up with the latest semiconductor technology and build the application with optimized software and hardware. We are an Official Partner of Sony's LDAC, and provide our LDAC solution to the other set makers. QCC5124 Quad-Core Processors QCC5124 architecture is engineered for high performance with low power consumption.

ES9219 x 2 The ES9219 SABRE HiFi SoC delivers audiophile-grade sound quality and output power, allowing the ES9219 to drive the most demanding headsets and provide a real line-level output to match professional audio equipment. The heart of the ES9219 ESS's award-winning SABRE DAC technology, with a HyperStream II modulator. This is the same architecture that is used in the world's finest audiophile equipment. High-quality Bluetooth codecs 5K supports the latest high-quality audio codecs, including aptX Adaptive, SONY LDAC, and AAC. Android 8.0 or higher supports LDAC by default. *iOS works with Bluetooth AAC 260kbps. 2.5mm BALANCED 4VRMS Balanced: Always Better Within any given audio system, the Balanced provides higher output power, better linearity, and lower noise than the Unbalanced. To the 2.5mm output, 5K works with Dual ES9219 DAC/AMP. *You will need to replace the existing 3.5mm UNBAL cable with 2.5mm BAL cable. 3.5mm UNBALANCED 2VRMS To the 3.5mm output, 5K works with Single ES9219 DAC/AMP. The ES9219 SABRE HiFi SoC delivers audiophile-grade sound quality and 2VRMS output power, allowing the ES9219 to drive the most demanding headsets and provide a real line-level output to match professional audio equipment. Automatic Battery Care 5K manages the battery for maximum life cycle, not for the time. Furthermore, 5K draws its system power directly from USB when working as a USB DAC. In other words, 5K does NOT draw any power from the battery when charging. It helps keep the battery life longer, and it ensures the same battery charging time even while streaming audio. 10-Band Pro-Grade Equalizer The embedded pro-grade equalizer is a vital benefit of 5K DAC/AMP over other similar products. It processes every incoming source audio from everywhere: Youtube, Apple Music, Spotify, iOS, Android, PC, Bluetooth(all Codecs), and USB. For more degree of freedom, 5K DAC/AMP supports parametric EQ in addition to graphical EQ. The embedded DSP cores perform double-precision 64-bit EQ processing, providing accurate and precise frequency response. 2-Way Associative Absolute Volume 5K always delivers the optimal Sound Quality, whatever source or device volume levels are. Any source volume level or device volume level will eventually control the 5K built-in Hybrid Volume System, keeping the source audio's original bit-resolution. No need to keep the smartphone volume or PC USB volume at the maximum anymore for the optimal Sound Quality. Adjust volume whatever comfortable way you like it. iOS/Android App 5K Mobile App enables the user to access every detail; Battery history, charger status, volume, DAC operating profile, DAC LPF filter, Equalizer, USB DAC sample rate, microphone gain, Bluetooth codecs. *5K is the only Bluetooth device that displays real-time LDAC bitrate. Silicon MEMS Oscillator The built-in MEMS audio clock helps ES9219 D/A Conversion perform its best. Silicon is inherently more reliable than quartz. MEMS OSC also provides 3000 times better Vibration Robustness than quartz OSC. 3-D LDS Antenna 5K delivers the optimal RF performance with high Sensitivity 3-dimensional LDS(Laser Direct Structuring) Antenna. The antenna is printed on the bottom case around the Red LED button.

Review: Great PEQ OVERALL AMAZING - I really enjoy the Qudelix 5K both on the go and at home when plugged in. I use it with my Punch Audio Martilo IEMs on a Tripowin 2.5mm balanced cable, and my Hifiman Ananda Stealth V3 using a Meze Audio 2.5mm to 3.5 mono silver-plated copper cable. Both pairings work beautifully in wireless mode at 2 VRMS. I don’t really take the Anandas outside, but around the house the Qudelix makes them surprisingly versatile and easy to use without being tied to a desk setup. The Martilos are my travel set — great for store runs and general out-and-about use. Wired mode is where things really step up. Listening to lossless audio through USB with both headphones sounds wonderful. Some people say you can’t really hear the difference between lossless and Bluetooth, but in my experience you can — especially in clarity and separation. Bluetooth still sounds very good, but wired lossless has that extra clean edge. When it comes to PEQ, this is where the Qudelix 5K really shines. The parametric EQ system is one of the best features. You can build your own custom PEQ profiles or load presets from well-known audiophile sources. It makes it easy to fine-tune both the Martilos and the Anandas exactly how you want them. Battery life has been excellent in my use. With the IEMs I get over 10 hours consistently. With the Anandas it’s shorter — usually around 5–8 hours — but I solve that by using a low-charge battery pack (important — low charge mode). With that setup I can stretch runtime to around 14 hours with the Anandas and close to 24 hours with the Martilos. For anyone who needs something portable but still powerful and flexible, the Qudelix 5K delivers. The fact that all of this comes in such a small device makes it absolutely worth it.
Review: The legend, the best, the only Bluetooth DAC for IEM - Qudelix-5k has been a legend for years on internet. I had always been wondering if there is a better option after so many years with so many new products. After conducting research extensively for several months, I finally decided this is it. Once it's delivered to my hand, I have been in love with it every day. Now I fully get why it's a legend. For my exact requirement, Quedelix-5k is one and only. I love music, but I cannot drop my work. Meetings are spread out from morning to evening, sometimes I am in office, sometimes I am driving. High quality mic is non-negotiable for me. I have to switch from music to meeting without too much hassle, like fiddling with wire or anything. For a portable DAC using IEM, there is no better choice. My voice is loud and clear, no voice latency that people can tell, I truly enjoy attending meetings using this DAC with my favorite IEM. Besides mic, the most unique feature of Qudelix-5k is its high quality software on Apple iOS. I need parametric EQ on iOS, and the EQ settings must be stored on device. No other device has software as awesome as this, others aren't even close. I can easily load the precalculated settings from AutoEQ, I can overlap it with my own, I can even enable cross-feed to adjust the sound stage. Given that I have HD 6xx and S12, but with good EQ even $20 IEM can be super impressive, the sound quality with low latency is undeniably awesome! Listen to me -- the Qudelix-5k software on iOS is truly outstanding. There is no alternative as far as I can see. I love how compact the device is. I clip it on my shirt and don't feel anything. I love how versatile it is to connect with phone and PC. Additionally, I can use it like a wired USB-C DAC, is there anything else more convenient than this? Lastly, at this price on desertcart, there is absolutely no way to find a better Bluetooth DAC with good software, high power, great mic, and exceptional sound quality. Actually, even the second hand DAC would be more expensive than this. This is the best deal on the market. If you have an IEM and wonder which DAC to pick, look no further, this is the right one.

## Questions & Answers

**Q: Does computer supply power thru usb when it works as dac or it work on battery power?**
A: Yes, 5K USB DAC gets the power source directly from USB VBUS.
It won't drain any battery power when working as a USB DAC. (Unlike BTR5...)
As you are concerned and asked us, it's crucial for all aspects.
Please refer the below page for more information.

**Q: Can i get full benefit of apple music lossless tracks on iphone 12?**
A: Yes, as long as you use this as a wired connection and with headphones that can reasonably play 16bit/44.1hz quality. Things to keep in mind: 1) The headphone is as good as the DAC, and vice versa. 2) Bluetooth is never really "lossless," but you can get approximates that are likely to fool your ears and thus be the same thing. Using the Qudelix as a bluetooth DAC will not give you "lossless" music output, but it will be very, very good. If you want true "lossless," you have to be wired. 3) On Apple devices, be sure to enable lossless output in Settings for iPad/iOS, or Music preferences AND in the MIDI launcher on Mac. Happy listening!

**Q: How can I pair this divice to a wireless earphones?**
A: It is not made FOR bluetooth earphones—IT IS A BLUETOOTH device itself!  Just plug in wired earphones & they ARE NOW Wireless Earphones when Quedlix 5 is paired with an audio source!

**Q: Is it possible to connect this to a pc via usb, then have the dac stream music to a bt headphone?**
A: Only if the BT headphone can be connected with a cable to the headphones.  Some BT headphones have a jack for a wired connection.

### ⭐⭐⭐⭐⭐ The Qudelix 5k: In a league of its own
*by J***S on July 5, 2025*

The 5k is a one-of-kind, highly configurable, reliable, portable bluetooth dac, which you can fully manage via software, on mobile nonetheless, via its app. The app, as well as the dac itself, really, are just perfect. Fully-featered, contioniously updated, and from an obviously passionate team. What truly distinguishes the 5k from competitors, and seems seldom mentioned, is that this thing just f***ing works, always, just how you want it to, on pc AND mobile. If nothing else, know this. You will not be dissatissfied with the audio listening experience it provides. For Android, especially, it really is the best, dac available, full-stop. There are plenty of competiting products with better specs, but hardware isnt everything. Optimization is essential. Crysis made that clear for video games, and the 5k makes it evident for audio. Such an exquiste, universabaly-reliabile and steadfastly- cohesive listening experience, no matter the enviromment, is offered by none other dac. No matter what operating system, software, or hardware you use it with, it does not dissapoint. Additionally, its support is unrivaled. Built by truly passionate developers. Look at the app's update and dac's firmware update changelogs, really. Now look at those from similar products. Insane. No other competitors offer such frequent, high-quality improvements to the users experience at no extra charge. Just one purchase guarantees users will get years of dependable, optimal use out of their device. Thanks to the frequent, high-quality, and most importantly free, improvements, and fixes to all users experience over time provided by the qudelix team. *Highlights* -Equalizer Settings are stored on device, no need to ever even touch them again after the first time. You get the same sound signature always. No swapping devices and suddenly it changes. -Syncs audio volume PERFECTLY no matter what. Regardless, If you change it via hardware buttons or software bars, on PC or Mobile. ------------ *Important Note for PC users* *Desktop operating systems dont have native support for and need third-party software to unlock full ad2p bluetooth protocol compatbility/functionality. You Can't use ldac on Windows without it. (lookup: "AlternativeAD2P Driver")* *On a side note, using it, you can also force SBC audio/ connection settings, and I was able to get the 5k to maintain an overclocked SBC output bitrate of over ~1.1Mb/s. Sounded better than LDAC. Insane. That software really is a game changer for windows bluetooth listening.
