I have owned and used many of these headphone DAC amps in the past ranging from all the Audioquest Dragonflys, Apogee groove, FiiOs, Hidiz, Ibasso, Hiby, Shanling etc etc and this little guy is the best by quite some margin. This has superb bluetooth range in which this will connect from the other side of my house with little effort a distance of several metres through walls and up stairs etc although I do use it mainly via USB C connection into my PC. The DAC chip used in this is not the most modern or up to date ESS Sabre chip but its not always about having the latest chip inside but how it is implemented and the technology in this little guy is pretty awesome with good engineering and thought processes in manufacture. What sets this device apart from the vast majority of dongles is the amazing software which you can use with it, I downloaded both the control app to my phone AND the superb Chrome extension on my PC to give you an incredible range of options like DAC filters, power range like high or normal to drive an impressive range of headphones. The app also gives you battery life and management etc etc etc there is simply too many functions to mention although I do have to give a very special shout out to the parametric equaliser function which you can search for your headphone in the drop down list and dial it in and save it (the dongle saves all your stored information in its built in flash drive and even if you switch it off it restores all of the settings you dialed in) this EQ function will give you the best possible sound to the Harman curve to basically optimise your headphones of choice or you can simply play with no EQ and completely flat just using the standard settings for sound which is also superb in standard mode. This level of control and flexibility is unheard of even with the FiiO control app you don't get offered half as much. You can just use this dongle as a simple plug and play device without using the app or PC chrome PC extension and it would still be worth the money on sound quality alone. I suppose if I had to nit pick then a 4.4mm balanced socket rather than the slightly dated 2.5mm one would be prefered but I do not used any of my headphones in balanced mode just the unbalanced 3.5mm supplied also, so to me that is not important. 6 stars all the way! Review: Lightweight Customisable Personal Hifi Device - While it is quite old compared to similar devices on the market, for my purposes this has to be one of the best designed personal hifi products available. Some quible about the construction but aside from the slightly loose buttons it is a very sturdy unit and the lightness is a feature not a bug (as much as I enjoy devices milled from solid blocks of aluminium and so on). I've come to appreciate the minimalistic milspec look and feel and the utility clip. I also like well thought out elements like the tiny nub on the Play/pause switch so it is easy to operate in your pocket by touch (the volume button is smooth by comparison). Other aspects I enjoy: - While not class leading the sound quality is very good indeed and the app allows you to tweak the EQ to your hearts desire to get the most from your IEMs and headphones. Sound is detailed and has pretty good separation and soundstage - all elements that can be tweaked via EQ. It's enjoyable enough that I don't find myself hankering after my other DAC amps when I'm listening to it. - Customisable - as with EQ most functional aspects of this device can be customised to your requirements. Both the phone and desktop apps are very comprehensive. You can upload EQ profiles via the Chrome app via the desktop app. - Rock solid and powerful Bluetooth connection - I can leave my phone on charge and move quite some distance from it without the connection breaking up. There's also something reassuring about how the Bluetooth light always blinks to confirm when you send any control instructions from your phone or other connected devices. - Powerful amplifier - you need to take care with volume settings as I've managed to blast my ears a couple of times - I recommend setting the volume up button to increments so you don't accidentally max out the volume while it's in your pocket. - Good battery life that seems to retain charge for many days while not in use. - Lightness and size - while wireless buds are more popular nowadays this tiny device is a great solution for turning your wired IEMs into lightweight and convenient Bluetooth earphones. ## Features - Dual ES9219 HiFi DAC 2.5mm Balanced (4V RMS) 3.5mm Unbalanced (2V RMS) - Qualcomm QCC5124 Bluetooth Chipset HFP / HSP / A2DP / AVRCP LDAC / aptX Adaptive / aptX HD / AAC - Bluetooth and USB DAC 96KHz/24bit with embedded double-precision equalizer - 500mA Li-Po Battery / 6~20 hours streaming - Plastic Body (Black) with anti-scratch UV Coating / Aluminium Clip (Dark Gray) / 52.8(H) x 26.7(W) x 15.6(D) mm (including Clip) / 25g ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B088F7C976 | | Audio Output Mode | Balanced, Unbalanced | | Best Sellers Rank | 20,774 in Electronics & Photo ( See Top 100 in Electronics & Photo ) 82 in Hi-Fi Amplifiers | | Brand | QUDELIX | | Compatible Devices | Phones | | Customer Reviews | 4.6 out of 5 stars 2,290 Reviews | | Interface | USB, Bluetooth | | Interface type | USB, Bluetooth | | Item Type Name | DAC Amp | | Item Weight | 26 Grams | | Manufacturer | Qudelix,Inc. | | Manufacturer Part Number | Qudelix-5K | | Material | Plastic | | Model Number | Qudelix-5K | | Mounting Type | Plug Mount,Clip On | | Mounting type | Plug Mount , Clip On | | Number of Channels | 2 | | Number of channels | 2 | | Product Warranty | 1 year manufacturer | | Smart Home Compatibility | Not Smart Home Compatible | | UPC | 860003628812 | | Unit Count | 1.0 count | ## Product Details - **Brand:** QUDELIX - **Interface type:** USB, Bluetooth - **Material:** Plastic - **Mounting type:** Plug Mount,Clip On - **Number of channels:** 2 ## Images ![5K USB/Bluetooth Amplifier/DAC with LDAC, aptX Adaptive, aptX HD, AAC (Dual ES9219-3.5mm unbalanced output; 2.5mm balanced output) - Image 1](https://m.media-amazon.com/images/I/81t923q63oL.jpg) ## Questions & Answers **Q: I'm thinking of using this or similar to connect my phone to my car system, sometimes by bluetooth, and sometime wired. arrrr - why word limit poo am** A: Works great in my BMW **Q: Does this have a usbc?** A: Yes, it uses USB-C to charge and connect to a computer **Q: Double checking. is there any reason to buy this qudelix off amazon if the fiio btr7 is going for just £8 more?** A: I noticed that as well, and swapped to the BTR 7. The Fiio is a bit better sound quality for me (a little smoother). I prefer the physical size of the BTR7 and the button layout also. The FiiO app has got better and now has PEQ presets, but overall the Qudelix app has more info and better options. I'd say unless you need the tiny size of the 5k, then the FiiO is better if you're paying about the same for each. **Q: Can ldac be eq'd? ive read that this is the only dac/amp that will allowed it but just wanted to make sure. thanks.** A: Yes you can eq and create and save more than one custom eq presets too.Also there is long list of eq presets installed to choose from - based on different headphone brands.Great little device but does make difference and battery is very good too. ## Customer Reviews ### ⭐⭐⭐⭐⭐ If six stars were possible this would have them! *by P***N on 25 January 2024* This tiny little DAC / Dongle is an absolute revelation in the world of DAC dongles!

The 5K is superior, and here is why: • Exceptional proprietary app, with instantaneous response time, undoubtedly the best on the market. Extensive EQ capabilities and customisation, making the devise a miniaturised professional amp. • Elegant and discrete design, with customisable light so you don’t feel festively decorated all year round. • Despite the minute design, the 5K has great control buttons, easy to locate and operate. • Truly integrated clip, which does not add bulk to the slick design. • Discrete battery life, 8hrs. • The crisp and balanced sound of the ES9219C DAC chipset. • Seamless automatic switching from Bluetooth amp to Dongle amp function (many other similar DAC amps require manual switching). • Finally, size and weight. This is the smallest and lightest Bluetooth DAC amp available. Mine is paired with IE200s and, clipped to the original Sennheiser cable, or 2.5 balanced cables by OpenHearth wrapped around the neck, is virtually impossible to feel. Obviously, a personal consideration but, based on my experience, the QUDELIX 5K is unrivalled in the space of ultraportable DAC AMPs. ## Frequently Bought Together - Qudelix-5K Bluetooth USB DAC AMP with LDAC, aptX Adaptive, aptX HD, AAC (Dual ES9219 3.5mm Unbalanced & 2.5mm Balanced Output) - Apple USB-C to 3.5 mm Headphone Jack Adapter - Sennheiser HD 490 PRO Open-Back Professional Headphone --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.om/products/314126971-5k-usb-bluetooth-amplifier-dac-with-ldac-aptx-adaptive-aptx](https://www.desertcart.com.om/products/314126971-5k-usb-bluetooth-amplifier-dac-with-ldac-aptx-adaptive-aptx) --- *Product available on Desertcart Oman* *Store origin: OM* *Last updated: 2026-05-30*
