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 β€” 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 β€” 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 β€” usually around 5–8 hours β€” but I solve that by using a low-charge battery pack (important β€” 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 Qudelix 5k: In a league of its own - 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. ## 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 - 2.5mm Balanced 240mWatt / 3.5mm Unbalanced 80mWatt - *The Qudelix-5K is a Bluetooth receiver designed to work with wired headphones or earphones.

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. https://www.qudelix.com/blogs/5k-dac-amp/usb-dac **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 earphonesβ€”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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great PEQ OVERALL AMAZING *by A***R on February 11, 2026* I really enjoy the Qudelix 5K both on the go and at home when plugged in.

Bluetooth headphones usually won't get loud at all. I can get an experience with this. Great sound quality, lots of options for EQ and other configuration, and plenty of driving power for big headphones. Durable too. I've dropped it several times, and it's so small and light it didn't take any damage. There's a lot of DACs out there but this one is lightweight enough to keep in my pocket. It's really light even in a TPU case. Would buy again. ## 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? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/221094688-qudelix-5k-bluetooth-usb-dac-amp-with-ldac-aptx-adaptive](https://www.desertcart.pt/products/221094688-qudelix-5k-bluetooth-usb-dac-amp-with-ldac-aptx-adaptive) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-04-22*
