Speaker Booster and Equalizer

This app is great even works on Bluetooth. Boost volume by 60% . Believe me I'm a audiofile and need my music loud . Both headphones and speaker ate louder

Wow, What a different to my phone speaker. Went up only16% make a whole different. I don't usually give 5 stars to any ap.

This is THE APP for more volume. Follow the 40 percent advise!!! This APP stays on until you turn the volume down. Works with or without headphones.

Great app works perfect tried a few others that didnt work then found this app I am amazed be a use my phone volume was horrible till I tried this, haven't tried it with headphones yet but with sound this loud who needs headphonrs

I've got 5 boosters on right now and let me just say ow

Awesome thank you so much please make more with dj equaliser sounds adjustable waiting for it.. Guys it real software not like other fake software.. Hatts off.. Fantabulous

Doesn't make any difference in loudness of sound. Was useless :/

Worked most of the time but sometimes it won't work

Made no difference on you tube videos. Useless.

Finally I hear my music. .make you wanna dance

Now this is cool! Most of these things never work, but this performs perfectly! Well done to the developers

i tried some apps like this but this is the first one what really works i highly recommend it, specially for asus users like me

THE DAMN THING KEEPS CASHING. AINT WORTH A F***** ????????????????????

Tried several others, this app has good amplification and superior sound quality. Well done Zeugmangel!
