Quite good. not the best

PLEASE ADD A REVERB/ECHO SETTING AS A SLIDER PLEASE!

It works as it should.

I needed something like this bad.
I have some bluetooth headset that has horrible treble, this addon seems to reduce it a lot. Hearing crackles in audio off youtube though not sure why

Indeed works with HTML5 audio but unfortunately this doesn't work with music/radio extensions.

Practical and really appreciable, especially when using Youtube as radio player (and coupled with Invidition ;) )

I had to stop using it as it made it impossible to change playspeed in every video player... I preferred to remove the addon instead of fixing it.
Still cool tho.

As an up-and-coming audio engineer and just a guy who cares what comes into his ears, this plugin is my bread and butter. The mono button is especially nice, I listen to some classic rock where LCR panning is sometimes bothering me and this is an easy fix.

I only have 2 problems with it:
- the plugin seem to block some functionalities, for example I can't view gif-s when it's enabled.
- sometimes it's sluggish to respond - this is very random and I have not managed to figure out why.

In the future it would be nice if it could be expanded with a spatialiser and a compressor, as a channel strip basically.

No significant issues with this, and an add-on like this is essential with windows 10 sound inadequacies.

Great functionality and beautiful design. Exactly what I need.

One thing: the lowest two bands (32Hz and 64Hz) work strangely. The 32Hz band seems to change higher-frequency component than 32Hz and the 64Hz band does not change anything.

It's not a bad little audio tool. I like the pre-sets.

I use this to fine-tune music on YouTube (bass specifically). It does that job perfectly, hence the score. However this Add-on breaks a lot of other video related services like twitch.tv and certain file/flash types (.webm) for me. You will have to turn it off manually in the Add-on menu and hard refresh the page to get everything working properly again. @Dev: A quick on/off button when clicking the icon would be great for this reason. Happy holidays.
