I Can’t Imagine Living Without This App!

It was always frustrating to hear some low level voices when I was listening to Podcasts on my Macbook Pro and walked away to do other things. And, as might be expected, music sounded tinny, but I didnt want to invest in computer speakers since my laptop is my 2nd floor computer and there isn’t a lot of room where I use it. This app has resolved both volume level for Podcasts and improved the quality of music when I want to listen to Apple Music while I work. I agree with the other reviewer who says it should be included or recommended with the purchase of every Mac. Most of us have quality speakers and/or headphones for serious music appreciation/listening. But the choice of putting on headphones or purchasing redundant and pricey speakers for multiple areas of our workspace or homes where use our laptops is neither possible nor practical. Boom 2 fills that vast void between low volume/ tinny sound; and Audiophile quality. Not only does the spoken word sound richer, clearer, with amplified volume, but Boom 2 also adds enough quality to music to make it enjoyable. Being able to adjust the EQ for each, makes a huge difference. Thank You!

Amazing! BUT...

I’ve had this app for years now. Just now writing a review that’ll get lost in the hundreds but want to show my appreciation.

This will totally change how audio sounds on your Mac. It’s especially apparent with headphones. If you’ve got weak headphones, this app will make them sound like a $200 pair. Your laptop’s internal speakers are still limited of course, but you’ll at least be able to make out the bass now!

That said, if you do any sort of audio editing or mixing, especially music, DO NOT route your DAW/audio editor output through Boom. I do amateur production and always forget I’ve got the default settings and Boom going. Doing so will sound great, but when you play the audio anywhere else without Boom, it’ll likely sound bad as you don’t have Boom’s equalization which is what you mixed to. Same reason you’re unlikely to make a quality mix on non-studio headphones or monitors. Pretty obvious for most amateur producers but for you Fruity Loopers, it’s worth mentioning. :D

The best option for audio minded people

I work in professional audio and find myself often bouncing around between my work studio monitors, home studio monitors, living room speakers, and various pairs of headphones. This app has been amazing to use to not only have more control over my listening experience, but to better match each of these listening environments with presets. Yes you should be using SMAART or Sonarworks if you're serious about tuning your listening room or speakers, but if you're looking for something much simpler to give you some basic control, this is the app to get. The only thing I'd like to see in future iterations of this program is the ability to use an RTA mic through an interface to properly analyze and equalize your listening space, along with maybe some guides for people who would be afraid to venture into something that advanced.
