Right click the Speaker icon in Windows (next to clock) and enable Windows Sonic as that can boost the audio a little for Headphones and sound a bit better too.

But yea get better wired headphones. Plus them into rear audio port, not front.

If using Motherboard Audio, make sure the official driver is installed, not one from Windows Updates.

Enable Loudness Equalization and Virtual Surround

I'm not an expert or anything but wouldn't this damage your ears?

Other than buying an Amplifier ? No, but any Stereo 2.1 set of speakers have their own amplifier, so you can set PC to RMS 50% volume (no distortion) and run the speakers to 100%. Plug headphones into the speakers' headphone output (make sure they have such at purchase time) if you have to use them.

get the correct chipset/audio/lan etc... drivers for the mobo from the mfg or oem site

Maybe consider reducing the noise of the air conditioner or creating some noise insulation, rather than beating noise with noise. It's not healthy.

or get better speakers/headset or amplifier

Get the room cooled off then turn it to low to keep it cool but much lower noise.

Also when you have a game opened up, ALT+TAB and right click Speaker icon and open Volume Mixer to ensure everything cranked up, as you could have Master on 100% but a game or app volume might be lower then that.

i forget which one, loudness equalization or room correcting... if you listen closely, one of them gives you a 10% boost past 100%

Boost Audio Quality: Increase Maximum Volume in Windows for Optimal Experience


Increasing the maximum volume in Windows can significantly enhance your audio experience, especially when dealing with low-volume media or less sensitive speakers. Here are several methods to help you boost the volume beyond the standard 100% limit, ensuring you get the best possible sound quality.


Using Loudness Equalization

Loudness Equalization is a built-in feature in Windows that helps maintain consistent volume levels across different audio sources:

Right-click on the speaker icon in the taskbar and select Sounds > More sound settings.
Head over to the Playback tab, select the sound device you are using, and click Properties.
Go to the Enhancements tab and check the box next to Loudness Equalization.
Customize other options in the Enhancements tab according to your preferences.
Click Apply and OK to save the changes.

Buy better AC

If the ac is so loud you cannot hear your games with maxed volume, the noise is probably damaging your hearing.

You should try to make the ac quieter somehow or get noise cancelling headphones.

Trying to fight the noise of the ac by adding more volume to the headphones is really not the right way to go.

Play around with the sound enhancements because two of my 12 speakers needs Loudness Equalization or they are so silent - just try to see if any of those toggles work in Sound Control Panel < Headphones < Properties.

move your desk or do you wanna be deaf by the age of 20?!?

What you need is a headphone amplifier, your current drivers can't get any louder
