IPhone, headphones and EQ with Apple Music. Is Qudelix-5K the only choice?

FrantzM said:
Is there a way to EQ my headphones with the player being an iPhone, in my case a iPhone 13 Pro.
Would the Qudelix connect to the iPhone (stupid) Lightning Port, and the headphones connected to the Qudelix via Cable or BT?

You can do iPhone->Lightning->Qudelix->Analog->Headphones
or iPhone->Bluetooth->Qudelix->Analog->Headphones
in both cases, you can use the 5K's onboard DSP.

the Qudelix cannot send Bluetooth audio to a set of Bluetooth headphones. It is purely a receiver

P.S. Ordered the Qudelix 5 K, yesterday via Amazon US, I'll get it in a month or so...

Ordered it for the second time since the first package got lost

So… let’s hope, but about your question: the Qudelix has 2 headphone’s jacks and it will connect to the iPhone via Bluetooth.

I’ve read of many problems with the cable connection on iOS, and I’m not sure the EQ will work. Did you try it?

I have not tried it, but am well aware what a pain the Lightning port is for connecting USB accessories. You specifically need an "OTG" cable for this to work.
I've had great success with this one so far: https://www.amazon.com/Oxygen-free-Adaptor-Amplifier-qudelix-Shanling/dp/B09KLXYQDH

And yes, you can use the EQ via USB.

What he said! USB cable must be “OTG” compatible. This one works too and comes in different lengths:

I’m hoping my voyage might help to give another insight into this issue. I have the iPhone 15 pro max, so after many years I can buy more mainstream usb c connectors. I like cables, but not when I’m travelling, so how best to get the sound into my ears, and with some EQ to help refine IEMs and/or headphones.

My setup now after a lot of messing about is iPhone > Bluetooth output > Qudelix 5k > cable to IEMs/hesdphones.

5k is amazing in what it does via the app, especially the Auto EQ function which I love. It’s not the best bit of kit, and I really dislike the buttons.

I really don’t want to go dongle DAC for a number of reasons: cable tied to the phone with a small block of DAC ballast in the mix. It is hard to find a portable DAC with EQ functionality too. Forget using the 5k as a possible DAC transmitter as it is only a Bluetooth receiver, as are most DACs that I’ve looked at.

If you intend to answer calls on your iPhone with whatever setup you go for, that creates more problems if you are wired up or do not have an in line mic.

You can buy a plug in Bluetooth transmitter for iPhone that will take your signal and send via aptx codec (as well as aac). You can then use your 5k as a receiver and mic. That gets into a whole other argument on whether you really can hear the difference between Bluetooth codecs. I’ve done lots of tests and much to my displeasure I can’t often pick out the best quality in blind tests. I’m just not happy settling for aac as I know there is better out there, and therefore I am a Bluetooth snob. Maybe idiot.

YMMV greatly when it comes to what you will or won’t compromise on. After LOTS of research you must have an OS that isn’t iOS to make EQ work systemwide. It may be that with the arrival of side loading apps if you are in the EU, you will have access now to wavelet and potentially the system wide EQ you crave. I’m in the UK so thanks to stupid Brexit I’m excluded from side loading.

I’m now looking at buying another DAP (Hiby R6 iii) as apart from calls this will do everything I need: streaming, EQ and even video. I can still use the 5k as a receiver into IEMs and as there are 2 sources of input I can take calls with my iPhone as and when I need to. It’s not a perfect solution, and certainly not a cheap one, but it will remove a lot of (unnecessary) anxiety from having a FOMO.
 
True, but I meant when it’s not directly connected to the phone. In terms of Bluetooth I meant it’s a receiver only as opposed to a transmitter also.

I have used as a usb DAC, and for me it’s not a very nice thing to dangle (or dongle) from a phone.

Hey Royalshadow,

Any particular reason you went with Qudelix 5k over Airpod Pro 2s? I currently have APP2s and I do enjoy them but as I dig more into the IEM world, I see a lot of people recommend Qudelix 5ks for portability.

Is it just the auto EQ pretty much?

Not necessarily true. Sennheiser, Sony, JBL etc all have apps that allow you to EQ their Bluetooth headphones to varying degrees. I mostly use their apps to dial down the bass on their consumer tuned headphones.

How does the Q5K compare to the BTR5? Which would you recommend? Pros and Cons of each?
 
Is there reliable information that this device can be used via USB with an iPhone (or iPad) with an equalizer ?? The only person who bought it uses this device via Bluetooth. The description of the device says that the DSP only works via Bluetooth. There is no information on the forums of the official website (Qudelix) either. To be more precise, there is a lot of information there, but it is not structured enough and they are not telling us something.

You can use the Qudelix's DSP with audio sent from an iPhone via USB.

the recent dongles from Fiio such as KA15, KA17 has the integrated PEQ feature :D
