New Head-Fier
Been listening to these pretty heavily today, they sound great wireless but they really shine even more when listening in USB mode. Aboslutely incredible!
1. How does the Dali IO-6 behave with power OFF but driven by an external amp? What kind of signal path loss are we expecting to have versus the same but with power ON?
It's a bit brighter. Seems more "clear" at first, but I'm finding the treble a touch fatiguing in direct mode with the power off. Powered on, the treble drops slightly and they sound a bit smoother.
Here also a review of the IO6 and comparison of the frequency response to focal clear.
Pretty identical curve, but the IO6 have a bit more bass.
And the vocal clear are called one of the best sounding headphones.

Mind you .. Even though the frequency curves seem similar, don't forget that the Focal are open back, the DALI are closed back ... As such the focal have a wider much more open soundstage ... I would be careful comparing them too much .. However, for a closed back pair of wireless headphones the DALI do indeed sound amazing
- My pair seems to have a pretty loud hiss, like other people already mentioned
- While music is actually playing at not too low levels the hiss can't be heard. But a lot of times it's quite present while listening to classical music in lower volume parts of the music. This seems unacceptable compared to way lower priced headphones I listened to recently.
- With ANC off: slight static hiss and electric sounding crackling sometimes
- With ANC on: slightly more static hiss but no crackling (the additional hiss is probably the ANC, which seems to be totally fine)
- With transparency on: same hiss as with ANC off and no crackling, but additional somehow "wobbling" noise
- In passive mode: all fine and none of the above occur
- The hiss is more present on the left ear cup. And the crackling with ANC off is only on the left ear cup. Maybe due to my left ear being bigger and there for nearer to the driver?
- As I couldn't read any of the hiss problems in the early posts in this thread, this may be related to a later production batch or a firmware update on later units? (after beginning/mid November)
- Does it matter in which mode I do the burn in (active/passive/ANC on/ANC off/...)?
- To address the hissing problem someone stated to burn-in the headphones (let's hope that this works)
- I am doing this at the moment whenever not listening to them with some noise generating youtube downloaded file, which was stated in this thread somewhere.
- Bluetooth connection randomly lost
- Last night I tried to burn-in via Bluetooth (forgot the ANC state used ;/). There was no music playing on the headphones when i woke up and the Bluetooth LED was off. The headphones were on though and the power LED was green. My phone (Oneplus 3 (Bluetooth 4.2 with aptX HD)) still showed the Dali's as connected and active and the music player (Musicolet) was still playing music.
- High pitched tone occurs sometimes
- Happened twice now and lasted for like a second. It seems to be related to the usage of the controls.
- Since there is no app, is there any necessity/possibility to update the firmware ?
My guess is that you either have a faulty kit or very good reference cansFrom my own experience with them (a week, 50h burn in) :
The hiss doesn't disappear with burn in. It's annoying but these headphones are supposed to be used outdoor so it's barely noticeable, if you wanted something to listen at home at quiet volume in a quiet environment i wouldn't have chosen these.
Firmware updates through the USB port should be possible but i have no idea if Dali planned any updates, i doubt so.
Otherwise i don't think they are as good as most reviews state, they sound kinda veiled, and the bass emphasis may be way reduced compared to Sony or Bose wireless headphones but still too prominent for my taste. The soundstage is not too narrow but not as wide as some may say, i know plenty of closed cans with a more expansive soundstage. They can sound boxy at times. The treble is smooth and rolled off and they lack some clarity for me. Some highlighted the great instruments separation but i also don't agree, they sound congested on rich layered tracks. I've also read that they sound more "audiophile" than the competitors but honestly they are just consumer headphones that sound less boomy and a bit more even than the big names, nothing to get crazy about.
Using them through USB sounds slightly better to my ears than using them with an external Dac. I used them with a Topping D50s DAC and SMSL SP200 amp (THX) and they sounded better (and way louder) using the built in DAC (surprisingly). Maybe the jack input sucks... (and how comes you get hiss and static noise with wireless off ? )
I'm still hesitating on keeping them, i wouldn't if they were around 200$ but at almost 400 they are way too expensive for the performance. I'm a bit disappointed, especially while i have some Dali speakers that i absolutely love !
Edit : hiss is vastly reduced to almost no hiss through USB connection but still a few faint static noises in the right cup, where the electronics is. They are probably poorly isolated.

Any chance you can name anything at -+200 which is comparable? I would be interested a lotI'm still hesitating on keeping them, i wouldn't if they were around 200$ but at almost 400 they are way too expensive for the performance.

I checked quite a few headphones yet, and those are the ones which I like the most by far.
I'm between the Dali iO-6 and the Beoplay H9i - used, the H9i is going for almost $120 less than an iO-6 where I am (Ireland)
Does anyone with both headphones (or who has tried both) have an opinion if the difference in sound quality is really that big between the two?
I'm looking for headphones with decent ANC - I have the h8i and ANC performance on that is perfect for me, don't need much more. However I also want to get the best sound quality possible with that ANC, so e.g. Sony XM3 or Bose are out. I tried the Momentum M3 and it was too fake-bassy for my liking. The Dali ANC seems to be getting very mixed reviews which is concerning.
