A WiiM Pro/Pro Plus or miniDSP 2x4HD would work.

With Line input and hardware DSP? Doesn't exist.
Bummer. I was hoping in our times of abundance that it will be easy to find one.
Makes me wonder.
So in short, there is no way to equalize a headphone amp-Output at least there is no super compact device solution. Check.
Ok thank you for your input!
Hmmm. I think I might have found one.
Could you please verify it is what I think?
A friend just suggested it

Is this kind of language even allowed here?
No. Why would you need an analog input on a portable wireless headphone adapter?
Why would it not be allowed? I can also say bee hive if you want. I do t understand where the issue is tbh
"No. Why would you need an analog input on a portable wireless headphone adapter?“
What is a "portable wireless headphone adapter“? I literally don`t know what you mean.
I need a headphone amplifier with Dsp Eq ability and line in. I never said it has to be wireless. Quite the opposite, it has to be wired
or else it wont work on a headphone line out signal unless i add a bluetooth transmitter which becomes a bit elaborate of a solution.
To your „No“ i just posted exactly this device unless i am missing something which can always happen.
It seems to be having a Line in and integrated Dsp
I want to Equalize the Headphone Output of a Digitakt 2 or any device that only has a Line Headphone output and does not support wireless connection protocols
If you stumble across any similar device and feel like sharing it would be appreciated

Especially with no support from the company anymore. But based on the specs it looks nice.

This is a kind of strawman argument; I was not talking about them. I was talking about the red variety, just as a side note. I do not want to derail this thread any further, so I think it's time to settle. And I did not mean to get personal, it's just the language that I'm uncomfortable with. So I apologize for the discomfort I may have caused here to you and others. Cheers!
I think the battery in my Q5K (purchased September 2022) is starting to show it's age, so i've begun preparations to attempt replacement.
1. Obtain Torx T5 Security screwdriver (AKA T5H). Purchased this kit from Amazon UK: https://www.amazon.co.uk/dp/B0D4426PY8 It's a lovely little kit and the T5H bit did it's job...
2. Find suitable replacement battery. According to the interwebs, the battery in the Q5K is no longer manufactured. I found a post on a Korean forum that suggests that a 3.7v LiPo 602035 is a suitable replacement. https://m.ppomppu.co.kr/new/bbs_view.php?id=mini&no=58772
Picture from KR forum...
3.7V LiPo 602035 batteries are available on ebay UK for £8.49, so I have ordered one. https://www.ebay.co.uk/itm/375695071234
(nb number relates to batter dimensions of 6.0mm x 20.0mm x 35.0mm which is the same as the original battery)
I have a couple of concerns about the replacement...
1. Original battery is marked as Li-ion, not LiPo. However, Qudelix refer to the battery as LiPo in all their documentation?
2. Orginal battery voltage is 3.8v, LiPo replacement is 3.7v.
Does anyone have any comments on this? I'm relying on an English translation of the Korean forum for info

Yes, and I think I already have given them here and/or on the Qudelix forum.
Li-Po is a subtype of Li-Ion. This is clearly a Li-Po, packaged in a flat soft pouch instead of hard cylindrical casing. This is not an issue.
The charger in the Qudelix will try to charge the battery to 4.35 V when the maximum voltage for 3.7 V cells is 4.2 V. This can very likely lead to overcharge and failure of the battery (even a structural one).
A workaround is to limit the charge to 80% in the settings (in practice it stops charging around 76-78% with the 3.8 V cell), but that way you will be losing a great deal of battery life.
The 682134 3.8 V battery cell is still being made (the 5K is still using it), but I believe it's a custom order for Qudelix, since it's unavailable for sale.
I still in search of a suitable 3.8 V battery replacement.
Hmmm, the 602035 LiPo is a few mm longer than the OEM battery...
The 602035 will fit, but I will have to trim the case a little (cut the back off the rectangular part that fits around the headphone sockets) or play about with the battery (which doesn't feel like a good idea). I think I will wring a bit more life out of the OEM battery before attempting this.

Rather than trim the case why don’t you attempt to trim the battery?,I’m sure you can remove a few mm quite safely
As a Battery management system engineer, I would say: Never do that!Rather than trim the case why don’t you attempt to trim the battery?,I’m sure you can remove a few mm quite safely
Thanks! I have considered removing the kapton tape and seeing if there is enough play in the protection board to shorten the battery by a couple of mm, but I think trimming the case is preferable.Rather than trim the case why don’t you attempt to trim the battery?,I’m sure you can remove a few mm quite safely
Hi all, my first post in this esteemed forum.

I'll probably just order new Qudelix, but if one has unused Marshall on a side, it might be good to know.
It seems that Qudelix is not the sole user, note the battery section in Marshall Minor IV teardown:

Would you like a splash of humour with your “obvious” post ?
