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.
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.

### ⭐⭐⭐⭐⭐ 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.
