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.
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.

### ⭐⭐⭐⭐⭐ Qudelix 5k: A must have for any IEM user
*by H***. on July 12, 2022*

I was looking for a portable DAC/amp for my IEMs, and I found the Qudelix 5k in stock at Amazon. It is a killer Bluetooth DAC/amp, and I cannot recommend it enough. Build Quality and design: The build itself is decent, but the buttons feel cheap. Also, the button placement took me a while to memorize. On one side is the volume up/down button, and on the other side is the power, play/pause, and track skip/rewind button. The latter button has a bump so you can feel it by hand, but it took me a long while to feel the buttons and use the 5k without looking. Power and sound quality: The 5k is rated at 80mw single ended, and 240mw balanced (at 32 ohms.) Yeah, it doesn’t seem like a ton of power, but the 5k can easily power all my headphones and IEMs, ranging from Focal Elear, Moondrop Blessing 2, Moondrop S8, and even the Hifiman Sundara (though out of the 2.5mm balanced output.) As for sound quality, I can’t tell the difference between the Qudelix 5k and my JDS Labs Atom+ stack. App: This is the main reason to buy the Qudelix 5k. It has an app for Android and iOS, as well as a Chrome extension for PC and Mac users. The app has tons of functionality. The eq section of the app is its main selling point. You get a 10-band parametric eq along with all of the AutoEq presets by Jaakkopasanen. It includes all presets from Oratory1990, Crinacle, and others. This is perfect for iOS users who want the AutoEq function. For example, I bought the OG Moondrop Blessing 2, and I wanted to try the Dusk eq profile. I can easily do this via the Qudelix app on my iPhone. Another feature of the app I really like, and one I don’t see people mentioning, is the battery section. It shows you at what rate the battery life is decreasing/increasing, and it also lets you set the battery limit to 80% to prolong battery health. Also, when the Qudelix 5k is plugged in to PC/Mac, it bypasses the battery when in use. Conclusion: I highly recommend buying the Qudelix 5k for portable use. My main gripe is the odd button placement, and that’s it. The app functionality is amazing, the battery life is very good, and it has enough power for all my IEMs.
