Thanks for letting me know. Bizarrely not working on my old Android 10 either, might be a Samsung thing. Starts and shuts down. I'll try on my son's phone later.FWIW the EarStudio v1.9.0 apk works just fine on my Pixel 6 Pro running Android 12.

Radsone EarStudio ES100
- Thread starter m4rkw
- Start date
I got the es100 connected to the app at last woohoo!
I noticed that the app would stay open with the Bluetooth off, as soon as I started Bluetooth it would close again after a short while.
So I started changing a few settings, when I changed output from disable to headphone amp it asked me to press the power button and now it's fine..
Thanks for your help.

Would love to know anyone pair this with 7hz timeless? What's the eq setting you guys have? I feel like wide mode with classic default is just better than narrow

I really got the earphones for studio monitors when I'm drumming as I was having to turn up my kz10's too loud to hear the track well enough to play along with but I've ended up attached to them most of the time now!
I'm using LDAC connection and having got used to the Dolby Atmos from the phone, I haven't really felt the need to tinker with the eq much, apart for fun. I've left mine on wide now, your right I think there is a tiny difference.
Short delay sharp roll off and x2 over sample.

Nice! What's the different of short delay sharp roll? Any improvement if set on that? I use 2.5mm balance 1x, output with Aptx codec along with foobar

Does the ES100 have "CAR Mode" and Line Out via 3.5?

yes it does. It says so on their website. I believe you just set the output to 0dB and Power Mode to 'Auto'Does the ES100 have "CAR Mode" and Line Out via 3.5?

No, mic and remote on the headphone cable won't work (I just verified it). The 3.5mm jack on the ES100 is TRS and audio-out only. If a TRRS plug is inserted, the 4th mic connector will be on common/ground (i.e. unused). This is standard operation for consumer electronics.
I want to connect my ES100 to my Philips X2HR open-back headphones. So I bought a 3.5mm TRS to TRRS cable (this one https://www.amazon.sg/gp/product/B00L6C8T22/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&th=1) but it doesn't work. i.e. no audio is transmitted when connected to the ES100 and the X2HR.
I tried to play audio from my DAC/AMP (Loxjie A30) using the same cable to connect the A30 headphone output to my X2HR and it doesn't work there either.
Have I got a defective cable? Or is the issue that I accidentally bought a TRS to TRRS cable? What am I doing wrong / what am I not understanding?
(Regular 3.5mm cables are working fine so the ES100 nor the headphones are the problem).

I believe you need TRS>TRS. The TRRS designates balanced signal, and the X2 is not a balanced headphone.I want to connect my ES100 to my Philips X2HR open-back headphones.

Would a TRRS>TRRS cable also work, or not?I believe you need TRS>TRS. The TRRS designates balanced signal, and the X2 is not a balanced headphone.
That's what I ordered next

No. TRRS CABLE will NOT work. It is ONLY for balanced headphones and the X2 is NOT balanced. You must only use a TRS cable. Others will not work.Would a TRRS>TRRS cable also work, or not?

So from what I've come to understand, if a 3.5mm cable is TRRS, the second R will be unused. This is because in TRRS 3.5mm, that extra R is usually for mic, not for balanced, since 3.5mm is never balanced anyway. Or am I wrong here?No. TRRS CABLE will NOT work.

TRRS to TRRS may work if it's a straight-through connector cable. The TRRS to TRS patch cable you got is for a specific video application and may have internal cross connections.So from what I've come to understand, if a 3.5mm cable is TRRS, the second R will be unused.

Well the 3.5mm TRRS > TRRS cable arrived today and unfortunately it doesn't work. When connected to the ES100 and my X2HR, I get sound but very low quality, no bass at all. Perhaps that second 'R' isn't behaving as you said (i.e. common/ground/unused). Wonder what it is.
Either way I've got a 3.5mm TRS>TRS now (https://www.cathayphoto.com.sg/phot...-sc2-right-angle-3-5mm-trs-coiled-patch-cable) which is working fine.

Problem with TRRS connectors in a TRS jack is that the spec is not that exact… sometimes they just don’t fit electrically. TRS cables is the way to go.Well the 3.5mm TRRS > TRRS cable arrived today and unfortunately it doesn't work.
