Mine will power off if there's no connection to the phone

Apparently the electrostatic drivers are very power hungry and were not tuned properly. I was very upset hearing the Roland initially but it's one of my favorites now after proper equalization.

Here is my Neutron filter for the Roland. It's based on normalizing the output to match my se846 using minidsp ears for the measurements: ../Music" bind="9" lock="0" preamp="-5"> <band type="PEAKEQ" gain="-2" freq="300" Q="2" /> <band type="HIGHSHELF" gain="3" freq="5500"...

I agree completely. For a company claiming high end audio, this is a total failure.

I'm using a Fearless Roland. It has no background hiss with any of my Dacs including ibasso dc02, Apple and dragonfly red or Cobalt. What is the output impedance? Could that be the problem?

A brief feedback on the new firmware for the Bluetooth dongle: Install process was fine on a Win 10 PC. Unfortunately, the background hiss/noise is no different (and awful). It does not matter what codec you use and I'm now concerned it's a hardware/design issue. I'm going back to wired and...

Exo Series Custom Bluetooth Cable (Copper (Type 6 Litz)) It has the new bluetooth module. The hiss is present with aptx or LDAC. Very annoying - went back to wired until they come up with a fix

I have the new plussound BT dongle with the Roland. It won't change the sound except it introduces a fair amount of background hiss. I'm hoping they fix that soon. On the other hand, just add some equalizer boost to the high end and you will like it much better. The special tweeters must be...

You can try the Shure BT2 aptx hd adapter. I did a ldac vs aptx hd comparison and they seem equivalent. The Shure unit is top notch but you would need mmcx connectors. https://forum.xda-developers.com/showpost.php?p=78863458&postcount=293

It has a microphone. I have no issues with dropouts (pixel 3xl using aptx hd). Great device!

Thanks. Did you test the RHA as well?

I am aware of some of the criticism of the Ears testing rig. But, the Shure se846 tracing I get is very similar to that of Goldenears published data. I've also tested the Oriolus, akg n5005, and that 4k spike isn't there. I like the Rha quite a bit, but personally cut that area back about 5 db...

I just got through testing them compared to the ME BT apt x and wired Test chain is a Pixel 2XL to the EARS: FR: Since the SE846 is so picky with source impedance, the Shure dongle must be quite low The red is wired (dragonfly red) Distortion/noise: The Shure with se846: VS ME BT (plain...

Long term break in effect? This is a frequency response graph using the EARS platform (Pixel 2XL, apple USBC DAC now/Google DAC initially) of when I first received them and yesterday. The bass response is enhanced after time, but it could of course been positional/seal change as well. For...

One more comment, my SPL measurements show about 115 dB/ V sensitivity which is higher than the official spec's read. You should do fine driving this with most DAC dongles and smartphones.
