We do running changes on our headphones, so some of the early issues with the headband - which only included a minor amount - were from the first production. We have fixed the headband issue a while back.

Hi, sorry for my late reply. Yes, this issue is also covered by the warranty, as we have seen this with some models.

I will forward your request to our Product Manager. :)

We are aware that some models may have an issue with the ON/OFF button. If you have received one of these pairs, you can contact your local DALI dealer and make use of your warranty to swap them for a replacement.

When ANC is activated and no audio signal is received, the DALI IO-6 will automatically power off after 8 hours.

Yes, this could also cause some leakage, but it is not given. Different heads and ears might experience it differently. Personally I tug in the top of my ears into the cups, while the earpads rest on my earlopes. This doesn't affect the bass performance for me. And I don't consider myself to...

I will say though that we have had positive feedback from users wearing glasses, so it really depends on the shape of your ears, your head and the arms of your glasses. The leakage in the graph is a forced leakage, so you might experience it differently. You can test it with a known bass track...

We've decided to share a measurement of the bass performance of the IO's, which illustrates how large an impact a leakage at the earpads can have on the low frequencies. A leakage can be caused by thick hair, by wrongly mounted earpads or by wearing glasses, which this test simulates. There's...

No, it IS taken out of the signal path, when turned off. :)

If I press my fingers at the headband, I can feel them too, but not when I'm wearing them. But I will note this and pass it on, so we can test it some more.

You can add an external amp, if you want. But you can't bypass the internal amp. You will then just add an amp to the chain of the signal path. But it is not necessarily a good thing. But you always have the option to turn the IOs off and run them passively through mini-Jack.

If it is a design issue, feedback is appreciated. But I'm not sure which plastic pieces that you refer to. The only contact between the headphones and my head are the soft earpads and likewise soft headband. I'm trying to recreate the issue, but I'm not sure if I quite understand, which pieces...

Here's a few comments on the "missing" or "thin" bass and ANC not working properly. In most cases, it's due to leakage of the seal between the earpads and the head or the earpads and earcup. 1) Wearing glasses causes a leakage 2) If you have "big hair" it can cause a leakage 3) If the earpads...

Have you guys reported this? Does any of you happen to have a photo of the issue? You can report it directly to our technical support through our website: https://www.dali-speakers.com/info/contact/technical-support/. I haven't heard about this issue before, but I will bring it up on our weekly...

I'm afraid that the IOs only officially support Windows og Mac via USB (not including tablets nor phones). But that said, you will experience that you might get it to work with some specific mobile devices.. A hack could be using a dongle (lightning cable --> USB A) in combination with a...
