## 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. Power consumption can be reduced by up to 65 percent compared to our previous technology for both voice calls and music streaming, and devices are optimized to support longer audio playback in virtually all operating modes. 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. Small & Lightweight The smallest form factor 52.8(H) x 26.7(W) x 15.6(D) mm (including Clip) Weight: 25g USB-C-to-C, C-to-A Cable included

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: Excellent Portable DAC/Amp if You Want Control and Options - This is my first DAC/amp. I bought it mostly based on the hype and positive reviews, and because I wanted something portable with a lot of flexibility. Overall this is an excellent DAC/amp for the price with a really strong feature set. Bluetooth supports most of the important codecs, and the balanced 2.5mm output is a big plus for something this small. In 2025 I do kind of wish it used 4.4mm instead, but it’s not a deal breaker. Sound quality is clean and has more than enough power for the headphones and IEMs I’ve tried. It also has battery passthrough and lets you set safe charging limits, which is a nice touch if you care about battery longevity. The app is one of the best parts. There are a ton of options, it’s actively updated, and it feels like the developers actually care about supporting the product. Build quality seems fine for daily use, but it’s basically a chunk of plastic with a clip, nothing fancy. The buttons take some getting used to, and there’s a lot I still haven’t messed with yet. This probably isn’t the device for someone who just wants super simple plug-and-play. But if you want flexibility and control in a small portable DAC/amp, it’s hard to beat for the price.

## 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.

**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.

### ⭐⭐⭐⭐⭐ EXCELLENT, worth the price (I think?)
*by M***S on December 26, 2025*

The Qudelix 5K truly is an awesome product. Don't know if it's exactly worth the price but it certainly is excellent. I've been using it paired with Truthear Hexa IEMs and with an iPhone/Mac/Windows PC over Bluetooth and USB (for each device). It's a great product effectively delivering a GREAT sound quality. I can't hear any difference with my IEMs used directly with the cable. It's awesome for this. With such IEMs, power will never be a problem as you'll completely annihilate your ears before you reach half the full volume of this thing. The volume automatically syncs with your device's so that it always delivers the best audio quality no matter the volume set on the source device (you don't have to worry about absolute volume on Bluetooth). The app is incredibly full of options. There's settings for EVERYTHING. I never had any lag when changing the settings, they're well saved, it's responding lightning fast, you can set an EQ with up to 20 bands... I can't say much about durability yet, but it's very small. I could fit two of these products inside a single hand. The clip is really good so I can attach it to my jeans, vest, or anything really. It's light enough that if it ever falls, the cable of the IEMs will retain it from falling. Oh and also, you can connect (simultaneously) up to 2 devices over Bluetooth as well as an additional device over USB (all 3 at the same time). It switches very intelligently and quickly over these 3 devices. The integrated microphone isn't very good, but I'm pretty sure no one will buy this product for that. If needed, you can plug in an external mic to use with it. It works flawlessly and is also available to set up within the app. If you're wondering whether you should buy this product, just buy it. It's EXCELLENT.
