Qudelix-5K Bluetooth USB DAC Amp with LDAC, Aptx Adaptive, Aptx HD, AAC (Dual ES9219 3.5mm Unbalanced & 2.5mm Balanced Output)
Qualcomm QCC5124 Bluetooth Dual ES9219C SABRE HiFi DAC 3.5mm Unbalanced 2.0V RMS 2.5mm Balanced 4.0V RMS aptX Adaptive, LDAC, AAC, aptX-HD The experts at Qudelix wanted the device to work as a universal DAC/AMP for both high-sensitivity IEMs as well as high-impedance open-back headphones. Qudelix wanted it simple, small, yet but powerful. In addition to the sound quality and the maximum output power, they also needed to consider the battery time as well, concerning the nature of the device. Qudelix’s engineers tried many DACs and Amplifier ICs and found ESS9219C is the best option for their goal. Besides the sound quality, the primary advantage of ESS9219C is that the built-in amplifier delivers the maximum output voltage up to 2V RMS. Furthermore, it supports the 1V RMS option at the same sound quality to save power consumption. For high-sensitivity IEMs, the amplifier noise figure is the most important. The high-sensitivity IEM is so sensitive that it translates every electrical noise or thermal drift into audible acoustic sound, usually white noise. On the other hand, the high-impedance headphones require a higher power amplifier. Those headphones usually have low sensitivity, and they are free from the white noise affected by the amplifier noise characteristics. Instead, they need higher power from the amplifier output to deliver enough loudness and headroom.

I tested this out on my PC38x and my Samsung S10 Plus and the app provides a ton of detail.The app separates phone volume and the Unit and it pushes headset much higher than the phone amp and the sound is noticeably clearer as well. Price is better than Amazon so I'd say to grab one or two from Drop if you're willing to wait for shipping.This thing is surprisingly tiny![image]Only downside so far is that the physical buttons aren't responsive. Sometimes it gets my command to up the volume and sometimes it doesn't.

Believe the hype - the Qudelix 5K is such an advancement over other pocket DAC amps that it’s ridiculous.The star is the app, which allows for nerdy levels of sound customisation. You can use parametric EQ or a ten-band graphic equaliser. You can choose from hundreds of preloaded PEQ presets that cover just about every headphone and earphone in existence. That lets you get the sound tailored to your preferences, no matter how much of an audio nerd you are.Power-wise, the 240mW on balanced (2.5mm) output is good enough to drive 300ohm-100dB headphones, like the HD650 adequately, with some headroom left to spare. On the single-ended 3.5mm output, you need to crank both device and Q5K volume up to near maximum for the same kind of results. On more sensitive, ...

On more sensitive, low-impedance devices, like the Blon BL-03, for instance, you need to dial the volume way back. I listen with about 25dB of headroom for those (on balanced output).The app has too many functions to list, but they’re all laid out intuitively, and reward experimentation. Plus, Qudelix updates the app and firmware regularly and takes user suggestions on board for new features. The option to have the device charge only up to 80% (thus extending the life span of the battery) is an example of the latter.Other good features include:-- The ability to have the device power on or off depending on what it’s connected to.-- The ability to draw power from USB selectively - you can disable charging when it’s connected to a phone, for instance, so it does not drain the phone’s battery.-- Super-fine-grained volume control.-- EQ settings are saved to the amp, so you don't lose them when switching devices.Battery life is decent - but not stellar if you're going to be using it in balanced mode all the time.The button placement and design on the Q5K is perhaps the only flaw on an absurdly well-crafted, well thought-out product that punches well above its category.

The buttons don't feel substantial and there is some creaking to the plastic body. But that's the only niggle I have with it.All of this to say that if you're an audio enthusiast or just someone who uses wired headphones, the qudelix 5k is a game changer and an absolute worthwhile investment.

I love this little device! Its mighty powerful, super clean and crisp, great imagin/soundstage and very dynamic too. The Bluetooth is a beast the range is quiet remarkable, clean with no hickups. I use the Qudelix 5k mostly wired as a dac amp, sounds alot better wired than wireless naturally. But i must say im very impressed with Ldac. Definitely getting closer to wired than the other codecs. Battery life is great it varries quiet abit dippending on the modes you use i.e Lfac performance mode balanced will drink alot more battery than other codecs or wired... Wired with charging off ect, it doesn't drop in battery (i do find this odd- ive literally never had to charge it). The app is what makes this dac amp the big winner vs fiio btr5, its simply put so feature ... MoreI love this little device!

The app is what makes this dac amp the big winner vs fiio btr5, its simply put so feature reach intuative the eq and filters are phenomenal and stay on the device regardless of what source im using, its literally the main reason i got it over the Fiio, that and the minimalistic design, no glass smaller ect... The only thing i dont like is the buttons, while usable and doesn't cause me any issues besides trying to remember which one is the blue(on) button bassed on the clip orientation and that they feel cheap... On a metalic body that looks and feels more premium. All in all great buy, im super happy and highly recommend it.
This is a Brilliant and tiny bit of kit that will slip into a shirt pocket and change your listening.It has one of The most complete and competent app that I have used, so much so that a screen on the unit itself is redundant (BTR7 take note!). You can fine tune it to whatever iem's/headphones that you want via build in presets from Squiglink, and you can import to and from that site!It is plenty powerful for most headphones and handles iem's with ease. Pretty much whatever you want to do on the go it will handle with aplomb, it is That good.
A product that totally exceeded my expectations. Served its purpose perfectly between being connected to a PC during the day for audio duties (including processing audio from my headset mic) and then via Bluetooth to a mobile device for music listening and also then connecting to a PS5 for gaming.Seems to drive all my headphones/headsets well and has a great set of features easily controlled by a genuinely useful mobile or Chrome app.Superb!
The dac/amp is really clean, about as clean as the competition atleast and can easily drive my HD58x even using stock unbalanced cable. The device lacks support for MQA and can decode only upto 24bit 96Hz, though i don't think i will be able to hear the difference in higher sampling rates. Bluetooth connection is solid and the companion app is near perfect, the devs listen to feedback and have improved the software since launch. Switching between bluetooth devices is seamless, PEQ implementation is next level and the app can download and apply EQs for the model you select directly from AutoEQ repository. The EQs even work in wired/LDAC mode. The only gripes I have are that the buttons are very exposed and are easily pressed by mistake and that the the device doesn't ...

I powers up my Shure 201, ATH MX30 and T2s easily. Good battery backup and simple button operation. Only thing is that the buttons are very soft that it can activate accidentally. Also the shirt clip is too soft that it does not hold properly so I DO NOT TRUST those clips. Metal body is good and durable. I did not like the fact that when you are in the call via bluetooth and touch the device it produces great noise that irritates us. This is not meant for the bluetooth calling but they could have made it perfect otherwise dropped the feature. Overall it is ok for the price (11k INR) I hope it lasts little longer only time can tell that.
Hi everyone, This was my second purchase from CK and I'm happy with the price and product as well.This was my first ever dac that too wireless 😁One there is not heating issue and the battery lasts more than 12 hours on 3.5 jack. And 9+ hours on 2.5 jack. I use with full volume on mobile and 25 steps on 5k. Also Ldac is always on.The sound output is really really impressive for a wireless dac. I say this comparing it to my Abigail Dac. This 5k has neutral tuning with slight boost in bass.The Bluetooth range is super good gives me great signal all around my house.Now the highlight of this dac is the PEQ come on i thought it was a gimmic. But after using it does make difference.Lastly the App is really convenient to use with regular firmware updates.I have ...
