I always have an issue with things not being loud enough and this helps out very very much. Does exactly what i need it to do. And thats most important.

Fonctionne exactement comme je voulais

Simply the best!

I love this add-on! Before I found this, sound was way too low on many websites, especially Netflix and AppleTV.
