TIP #1:
If your G2 stock earbuds fit your ear canals really well, see if they fit on your other earphones!
I tried these G2 ear buds on my ie-80 in-ears and i can honestly say they give the best seal i have had in 7 months since getting these earphones!
The G2 buds have an abnormally large hole diameter which allows alot more high/mid range through than my previous sets. Stoked!

TIP #2:
Clean your in-ear headphones regularly, scotch tape works great!
Pull off the earbuds and carefully dab (do not rub) each the earphone housing speaker grills repeatedly with sticky part of the scotch tape to remove any wax/dirt buildup.
Repeat this once every 1 - 2 weeks to ensure longer life/good sound of your earphones.
If possible store your in-ears in a clean container/sealed carry pouch so they do not collect dust/lint/dirt from your pockets.

Great to hear!

On a note of personal note, i had viper4android installed on my LG G2 but with these modifications,
i ended up uninstalling it as i was primarily using it for volume boost purposes as opposed to signal shaping/eq-ing.
I also found that viper4android would work randomly with some files but not others.
IMO Volume boosting should work consistently at all times, across the board.

From the purist/consistency train of thought this volume mod will give you consistent volume boosting and more power to your headphones (fuller sound) without altering/degrading the already superb audio signal, or adding digital noise.

That being said, viper4android is a great app for shaping the sound signature, which is what it is primarily designed for.
For me, "the closer to the original source, the better"

Soliciting for "thanks" is kind of lame especially considering I saw this mod first in the link you provided in the OP

This is an external Speaker and Headphone Volume level modification.
It is what I feel "should have been" the stock "happy medium" audio levels for the LG G2.

The DAC audio quality coming from the LG G2 is excellent.
This modification brings the listening sweet spot down to 50% volume level instead of the 80-90% volume range at stock.
Stock levels did not push test headphones as well.

Benefits:
- Removes the need for 3rd party audio VOLUME BOOST apps
- Does not alter DAC raw audio signal quality
- Provides optimized signal drive for higher ohm headphones
- Improved audio fullness
- Improved low end at optimal listening levels

This MOD works with:
All LG G2 Carriers

This Mod Affects:
- External Speaker Volume (boosted to optimal levels)
- Headphones Volume for all audio Bit-rates (boosted to optimal levels)

Requirements:
- Phone must be Rooted: http://forum.xda-developers.com/show....php?t=2448887
- Root Browser (or similar File Explorer with system access)
- Modded "snd_soc_msm_Taiko" file (see instructions for link)

Test Media Players:
- LG G2 Stock Audio Player (much lower digital noise on track pause compared to Neutron)
- Neutron Media Player

Test headphones:
- Sennheiser ie-80 (16 ohms)
- Audio Technica (38 ohms)
- Beyerdynamic DT-770 (80 ohms)

Test Audio Sources:
- Multiple Music Styles (808 hiphop, trance, reggae, jazz, etc) in multiple bit-rates from 320kbps mp3 to 24-bit/192KHz Flac.

Parallel Testing with:
- Stock IPhone 4s

Instructions:

On your phone:
1. Use Root Browser (or similar File Explorer) to navigate to: /system/etc/snd_soc_msm
2. Locate the file called: "snd_soc_msm_Taiko"
3. Copy this file to your storage as a backup in case you decide to revert back to stock.
4. Download the "snd_soc_msm_Taiko" file to your phone: http://www44.zippyshare.com/v/67179492/file.html
5. Once complete, paste the downloaded "snd_soc_msm_Taiko" file into: /system/etc/snd_soc_msm
Choose yes to overwrite the existing file.

6. Restart your phone, and test external speaker and headphones with starting with volume at 0%
7. If this improved your G2 audio, say thanks, and enjoy your music!
