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.
Review: EXCELLENT, worth the price (I think?) - 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.

## 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.

### ⭐⭐⭐⭐⭐ Incredible little DAC!
*by S***Y on November 26, 2025*

This little DAC is incredible! The Bluetooth is reliable and has great range, along with the ability to control almost any settings you can think of. The battery lasts as long as I could reasonably want and its wonderful to be able to simply unplug it from my computer to switch from USB mode to BT mode. The custom EQ is obviously a huge selling point of the device, and it doesn't disappoint. While audiophiles will argue to the ends of the earth about how various BT modes might sound, nobody could reasonably pretend that any of that makes half as much of an impact as a good eq! The audio quality is incredible, and the ease of use is even better. Near instant device switching, a fantastic app, easy to use EQ, and a convenient form facto really make this the one adapter to ruel them all.
