1. It's awesome.i am saving giving this app the fifth star for some minor tweaks to the audio engine... while it does maximize the sound quite nicely, i still find myself choosing to run neutralizer whenever i don't need a volume boost... this app is close in quality of equalization, but comes up just shy, mainly due to the muddy sounding low end, which is the end of the audio frequency range that i am often most interested in maximizing its fullness and clarity... anyway, with some clearing up of the sub and bass ranges of sound, i will happily give you all five stars...It's alright and does a decent job.
2. The good staff is that when it works, it transforms the headphones in a super power house, you feel all tue instruments and there are few handy adjustments to tailor the sound to your liking.6* for the sound when the app works properly, the way it recalibrates the sound is incredible.
3. The main problem for me is (tested with Huawei mate 20 lite so far) the fact, that after calibrating headphones (FiiO F5) it works fine for a few days, then it just wont produce the same sound.
4. A button to reset/ clear cache or whatever is needed to make it work, would be greatPlayed around with the paid version for a while trying all aspects of the app, thought the sound was pretty good at first.
5. This app listens to your headphones range and makes a sound correction, after that you're free to edit the EQ and add bass, etc.
6. BEWARE: The On/Off button it's a lie, when it's off your headphones sound way worse than usual, it's misleading and dishonest.
7. Being a musician, sound quality is something I'm very picky about when it comes to my headphones.
8. More customizable settings than the average person could possibly take advantage of, auto optimization of any set of headphones, an online library of user-uploaded presettings, auto-detect genre feature that will change the eq to whatever is most appropriate for the current track... Just try it.
9. It doesn't always start automaricly, it is not responsive when i make adjustments and when i use the amplifier volume there is an unpleasant screech sound.
10. It gives you a good blend and full range of sound for everyone's preference.
11. It's very easy for some of these apps to make even the highest of quality earbuds sound very mid-range biased.
