connected to my headphones, so I could have portable Bluetooth headphones. It is pretty loud, but only for the high treble. If the singer makes an S sound, it's this really uncomfortable loud hissing noise. It's not a audio artifact like crackling or popping, but just this treb that sounds way too high and loud.
 
I tried various earbuds and, and headphones, but they all gave out way too high of a treble.

Is there a way I can fix this? I really want a hardware modification or attachments to permanently reduce the high treble.
I don't want to plug in the headphone amp only to have the high treble boosted even louder. Something needs to drastically reduce the treb.
 
 
i took out completely the 16khz and 8khz bands in windows software equalizer "Hear" and it helps alot...but has too high latency., so not good for gaming. plus a hardware mod would be nicer and compatible with all audio devices

Regarding the photos, I wired to AA batteries to get longer battery life. About 20 hours instead of six hours under AAA batteries! I just keep the thing in my pocket. Plus eneloop rechargeables are awesome

Bluetooth audio adds further data compresion to already compressed audio (if using mp3). Some bluetooth transmitters/recievers can provide higher bandwidths and data transfer rates, I suggest you read up on the various versions of bluetooth and maybe go for one that has a higher bandwidth to try and improve audio quality.
 
The only hardware modification that will improve things is bin that device and unfortunately use.. wires

dang. i wish i could just open the device up and solder something on there.
 
what about using a portable amp (powered by one AAA batt) that is supposedly "bass-heavy"? i am hoping that would equalize things into a bass heavy sound and lessen the sharp treble

An idea.. you could try using an impedance increase adaptor, I think you can get them from UE.. as I got one with my TF10's. In my experience It reduces treble but will also have a hit on overall volume.
 
If you are in the UK and can't source one, I'll send you mine if you pay for the postage... and I can find it !)
