Has anybody used autoeq on these? https://github.com/jaakkopasanen/AutoEq/tree/master/results/oratory1990/harman_over-ear_2018/Sennheiser%20HD%20660%20S To me hd660s is very neutral and doesn’t need eq but I find autoeq rather nice. Its similar to true-fi, and aims to make a headphone more...

Can’t I use CCK to connect to es100 using usb to my iPhone? I can’t get it to work, it connects to Bluetooth. Edit l: my fault. The usb-cable didn’t transfer data.

I’ve by mistake put the charging cord into the audio-usb interface. I can imagine others have made the same mistake before. Will it damage the mojo? Is it designed for such mistakes?

Did you run hd650 balanced?

You didn’t run it balanced right?

Yep, it even drives the hd650 well. That’s what I’ve heard. But I’ve hd660s personally and it’s so nice to go wireless sometimes.

I’m using dt770 32ohm with my es100, bu I found it too v-shaped. Don’t think balanced would help that much. What did help was true-fi that makes the sound much more balanced.

Yep. You could also use it as a usb-dac if you’re anal about having it lossless. But can you hear the difference between alac and 256kbps aac? Do a blind test. Probably you can’t.

Yes, it is very confusing. I'm listening to 92dB now and it's not load at all..rather the opposite. Usually it's only recommended you listen for anything above 85dB for maximum 30min straight.

@wslee How accurate is Output Level Estimation on EU iPhones? They are capped due to EU law, so I assume that when the app is readin 90db the actual lever is lower?

Is there any sonical difference between 1x and 2x current unbalanced output? I'll be using dt770 32ohm as an office can, and I suspect the 1x current-mode can push them.

Tested this on my mac. In usb mode it's only a USB-DAC with no microphone. Using it as a bluetooth headset connected to my mac, it has both input and output.

Is there any problems with that in usb-dac mode it upsamles to 48kHz? SQ-wise.

Integrated mic somewhere?

Does the mic work deattached? If you want to use it as a headset in public.
