SpeakerAmp:Booster & Equalizer 4+

I have my MacBook Pro connected to a Harman Kardon, Onyx Sudio 4 and was able to eq my music exactly how I wanted it to sound. On top of that, if I want to add more amplication to the overall I can do that to the point of blowing my speakers so be careful with using the full range of amplification because you can easily blow your speakers.
Also there is a choice to purchase which gives more options that I didn't see necessary because all I wanted was to eq and the amplification was a bonus. The paid version wich I can use for 20 hours before having to purchase, is a bit more complex to change settings but I can see it extremely useful for a musician or producer. I like the simplicity of the free version and what all it can do so much I ordered another Onyx Sudio 4 bluetooth speaker to rock out on my desk! It does the job well with a lot of nice options like controlling individual amplitude gains on all of you audible bluetooth devices (giving more amplitude to bigger speakers and less or not at all to smaller speakers and computer or laptop). Very nice, I recommend highly.

The fact that this amazing, actually functional app is free, is in my opinion, beyond comprehension.

I am a long time Windows user who came to the Mac platform when my daughter gave me an older mid 2012 MacBook Pro which I have come to enjoy very much and use much more than my WIndows machine. However since my hearing is not quite what it used to be I was using my earphones or buds a lot to listen to various things on it. When I found the SpeakerAmp app searching for something that would increase the volume, I had to try it, especially since it state it was system wide. I kept looking for the catch, like a hidden trial or something popping up stating that now I would be charged to continue using it; never happened. I was in communication with the developer and asked about a donation page and was told a review would be sufficient.
I can't say enough about the app other than I am extremely satisfied!
Thank you again, for an amazing app!

I'm so glad that I found this app because it's been so useful adjusting the audio levels of my bluetooh speakers that I connect to my M1 and M2 Macbook Pros. Essentially instead of purchasing a desktop speaker system, I've been using my Sony SRSXB41, Lenovo, and JBL speakers with my laptop. Since apple for some reason doesn't have their own built in equalizer, this app has been awesome in allowing me to adjust the EQ for basically any audio device. Yeah it's really weird how those speaker manufacturers develop the speaker apps for an iphone or ipad only, and not the actual desktop/laptop computers. Well anyway, try this app out and see what you think. I bet you'll be like me an end up purchasing the pro version after the introductory trial is over. Don't wait, try this app now.
