Review: Ideal value for price, great features, but better sound quality is possible - This is such a good, balanced product in terms of features and price. But if you want better sound you can find it if you pay more. - it has good sound quality - it has great bluetooth connectivity, I can use it in different rooms, different floors, outside my bt source - LDAC significantly better sound quality than other bluetooth codecs, if you connect to mac or iPhone, use wire, because other codecs are hurting sound quality - I have it connected to 3 devices at the same time! 2 by bluetooth and one by USB and it picks the one that playes quite well. - I switched it eventually to be connected to mac by USB, same mac by Bluetooth and am Android phone, because mac does not support LDAC it hurts sound, but sometimes I just disconnect usb and go somewhere, so it switches from usb source to bluetooth in matter of seconds Connectivity of it is so much better than any other bluetooth device I have. Bose 700 does not connect half the time and take a minute to connect if it does, Topping G5 take a bit. This connects in a second, click, connected. The way how buttons are setup takes a bit of getting used to, app is good for nerds and equalization if you want to push your headphone somewhere else, but don't to make a reference headphones a consumer (V frequency response) curve headphones usually can't do that and it would only increase distortion and loose control. Battery life is better than Topping G5 which is 5 times the size and weight.
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.

## 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.

### ⭐⭐⭐⭐⭐ Unrivalled in the space of ultraportable Bluetooth DAC amps
*by Q***6 on 1 November 2025*

I used the QUDELIX 5K for a few months, sold it to switch to similar Bluetooth devices only to buy it again. 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.
