Should measure well and the build and styling look nice.

Not sure if I need 16W. Too high for headphones and too low for speakers. How the product support ends up remains to be seen. The RME support is top notch along with Firmware updates and YT video help. An interesting product for sure, however.

Save your money and go with a different brand. Grado drivers are all the same and if you actually look at the measurements for the various Grado cans yoi can verify the sound is basically the same too. I went from the SR60 on up to the RS1 and never liked any. Uncomfortable and antiquated at...

Switch to optical in from your source to isolate any ground issues. USB has really bad grounding issues.

How many times can we reinvent the same headphone. Almost as bad as Grado. Can you please address the lack of bass for the last 20+ years in all of your headphones?

Did I miss the "in-parallel" capacitor in your diagram? Most of the time a parallel capacity to a resistor changes the phase angle of the current and voltage across that component. This helps the current lead or lag the voltage.

The descending bass response and the variable and peaky treble make this headphone too bright for my taste. Bummer for sure.

What’s your budget for a new headphone?

I suggest first listening to the DT770 on a phone/tablet/PC and determine if the same tracks you listen to via record sound the same with the headphones. It is quite possible that you are hearing more accurately what records sound like. You should also try listening to your headphones through...

Try the RME ADI-2 FS. Excellent headphone amp, DAC, and has outputs that may be used for a preamp. The RME website and response to questions is also excellent. Another HUGE advantage of this unit is not only is it tiny, but it comes with an awesome parametric EQ. You can customize many EQ save...

Glad you figured it out.

No need to "upgrade" the DAC. Most decent DAC's these days that measure well sound so similar that you would be hard pressed to hear any difference. Most of the differences in sound come from the reconstruction filter. I would save your money and keep the Modius. I use mine at work all the time...

Something like this would work really well. https://www.etsy.com/listing/736284943/quad-4-headphone-stand-multiple?ga_order=most_relevant&ga_search_type=all&ga_view_type=gallery&ga_search_query=multiple+headphone+stand&ref=sr_gallery-1-1&frs=1&etp=1&organic_search_click=1

Waiting on reliable measurements and the distortion and frequency response should be considered before purchase.

Need a DAC too? Going to use a balanced cable? Amp only: THX AAA 789 Amp and DAC: RME ADI-2 FS

Are you clenching your teeth together during these 6+ hours sessions? Are you a teeth grinder by night? My suspicion is the headphones themselves are NOT the direct cause of the issue, but you may have TMJ issues from stress and clenching your teeth at night. Get a good night guard and see if...

DSD levels cannot be adjusted unless you convert it first to PCM. There is some discussion about this issue here: https://www.audiosciencereview.com/forum/index.php?threads/volume-control-when-playing-native-dsd-files.11438/

You won't hear any major differences so it would be a sidegrade at best. The DAC on the FX is very meh with tons of distortion compared to the O2 ODAC, but unless you hear it going with something else for now is probably not your best option. My suggestion is to first spend money on...

Try swapping the left/right wiring from one earpiece to the other. Does it follow the cable wiring or earpiece?

Any luck?

If there aren’t obvious signs of damage my next guess is a driver issue. Perhaps revert the driver if possible and try again.

Check your windows sound settings and be sure to do the following: Sound Settings -> Device Properties -> Additional Device Properties ->Advanced Tab Make sure bitrate and bit depth are 16 bit and 48000hz ( DVD quality ). Turn off Allow Application to exclusive control Turn off Give Exclusive...

When you mention your budget what currency is that in, USD?

RME ADI-2 DAC FS https://www.rme-usa.com/adi-2-dac.html The RME is excellent for tuning your sound as you have easily accessible balance and EQ controls. Plenty of power and current for planars while keeping things well in check for dynamic driver headphones. Benchmark HPA4...
