The Telex studio one headphones, are the only headphones that I know of that have treble bass & volume controls built into the cups they were slide controls.

Maybe bass and treble settings OR the volume control IC has gone bad. Basically, all analog signals processed by DAC fed from DSP will enter this IC for bass and treble control. If it is bad, no bass and treble control can get. You should bear in mind that the setting of bass and treble is good before checking the volume control IC.

Hi
3 possible solutions:-
• Adjust the Windows volume control - select the speaker icon from the Settings Charm or click the arrow on taskbar to show the hidden icons in Windows desktop mode, then click the speaker icon. Ensure that the volume is turned up and the sound is not muted. Adjust the volume, bass, or treble controls to eliminate distortion.
• Reinstall the audio driver.
• Disconnect any headphones from the headphone connector - sound from the speakers is automatically disabled when headphones are connected to the computer's side-panel headphone connector.

I also give a link below to a page from which you can download the full manual for future reference.

I would guess it is Volume control OR Bass & Treble OR Balance. Does it have a Microphone? Volume for the Mic?

Hey there, the problem with your sony is not a hardware problem, the headphones are completely fine, its the amount of bass you are putting into the headphones, there are two solutions to this, if you're using a mobile device (Apple, android etc...), go to your app store and download an equaliser e.g poweramp, with this, you can adjust the sound going through to your headphones using the built in equalizer (usually 5-10 bands, research this if you have no knowledge of equalisers), you can use this to turn down the bass frequencies in the sound, or the only other thinkable options are if you are already have an equaliser in use, turn it down, because putting all of the bars to the top makes the sound horrible, research on some suggestions for equaliser presets (another word for equalizer settings), or just turn the volume down.

the reason this happens is because bass naturally overpowers treble, and if it is too loud, the treble and mids will be significantly quieter, headphones are a menace for this, so all you have to do is tweak the sound a little (using an equaliser) to find that perfect balance between the different elements of sound.:-) :-)

Hope this helped mate :-) :-)

The realtek chip should come with the HD audio manager in the control panel if the drivers were installed correctly.
You'll want to check and make sure the equalization (under the sound effects tab) is set to none, or possibly to treble (I had to use the treble setting on mine if using a sound system with a subwoofer).
Another trick to raise the frequency of the audio is to raise the "Karaoke setting which will pitch shift all frequencies upward.

Use Z-enhancer to select custom (you may have to hold it down for 2 secs)
A-M button then selects or bass treble settings.
volume up/down changes the setting

Press in on the volume control repeatedly to step through the menu of audio functions. The
first option is Volume, followed by subwoofer (only if the subwoofer feature is currently
activated), Bass, Treble, Balance, Fader and back to Volume. When adjusting audio functions,
the unit will automatically exit audio control mode after five seconds of inactivity
