As someone above pointed out, Qudelix is a tiny company. Small upgrades within the current form factor (possibly allowing for button relocation) might be possible. I think their Chrome plugin is close to brilliant though could benefit from some usability improvements around entering custom PEX...

Really, you have to do EQ with almost any headphone if things like emphasized treble or bass are spoiling your listening pleasure. These are the things that are possible to fix. On a Mac you can use the brilliant SoundSource with either fully custom parametric EQ or with AutoEQ. While it...

Macbook Pro (14 inch, 2021) is an awesome source for the Aeon 2 Noire. This is the back-to-the-goodstuff Macbook Pro with a headphone jack, Magsafe charging port, SD card slot, and HDMI port--no more effing dongles required. Well, at first I was using this source with my Qudelix 5K using USB-C...

I have had mine for about 1.5 years. No hardware issues. I have done 4 firmware updates. The first took 2 tries. Maybe that one contained the "improve firmware update" feature. Three others were smooth, fast and worked first time. I would say the hardest thing is switching between sound...

Me, too. A little heavy but otherwise great. Not a believer in exotic materials: manage out resistance and interference; provide mechanical reliability--and your done.

I have 1.12.7 as of 2/25/2022

Clever to put it around the case so you can use the screen. Doh! Nicely done.

Check to see if Oratory 1990 has EQ settings for your IEMs. He actually listens to what the EQ does and tweaks a bit based on his judgment. He also designs the EQ to have simple to apply broad adjustments to suit your own tastes--for example, for overall bass, for sub-bass, for overall treble...

Congrats--Enjoy! I don't use the pads as I want the transients and punch. But, I do use Oratory 1990's EQ (not the AutoEQ generated with his measurements) with the Qudelix 5k PEQ. I lessen his bass boost a bit. This EQ also deals with a couple of peaks and valleys in the treble and cuts the...

I received my Aeon 2 Noires today. My, oh my... Compared to the Drop DCA Aeon Closed X, which are pleasing, the Noires are a dramatically better experience. Without EQ (e.g., EQ is flat) using the Qudelix 5K with balanced cables the sound is much more compelling. Bass is punchy, mids are...

Are you aware of any other battery operated dongle with higher power? The 5K provides 240 mW in balanced mode. The iFi Blu provides 245 mW balanced. Unlikely to be a detectable difference. There are a couple of dongles that get up to around 160 to 180 mW with a single-ended connection, which...

I think the device is worthwhile whether you use Parametric EQ or not. Many comments describe how the positives outweigh the negatives. I'll point out that if you use the 5K with one output device and one set of headphones, once you set it up it is the best personalized dongle. With that you...

There seems to be a lack of precision in defining "warmth" and a bit of disagreement in what it means. More bass and low-midrange than upper mid-range and treble seem to be most consistent across various definitions offered. The challenge seemed to be over whether "warmth" is meant to be a...

I have this question, too: - is it the precision volume knob?

Ah--missed that. No, certainly not in IOS. But, rare in all but the most advanced systems. It makes sense clinically because hearing deficits do vary with frequency.
