Chosen Solution
I have a UE MegaBoom 3, and a JBL Charge 4. My iPhone uses R&B as the equaliser. The Charge 4 takes every song I throw at it like a champ. The bass is fine, and slightly reduces if it’s too loud. The UE MegaBoom 3 however is making a ‘thunk’ sound for its bass when the volume is above 50%. I’ve used smaller BT Speakers, like the Dell ad211, and when the bass is roughly 70%, it makes the same weird ‘thunk’ sound with the bass.. and it sounds terrible. However this is a very old speaker.. 10 years or so. Could anyone else test for me to see if they can reproduce the issue? If this cannot be reproduced, have I got a bad UE Megaboom 3 speaker? iPhone EQ = R&B Song: Flawless - The Ones. Alternatively, use this song. https://www.youtube.com/watch?v=8b-FEaGJ… I’d ask on the Ultimate Ears reddit, however they only have one moderator or something, and it’s closed to invitation only and there hasn’t been a post for literally 30 days. The slash is basically dead.
Ultimate Ears reddit site is open to anyone with a Google account, you’ll need to make an account to post anything there (no different than here on iFixit), here Google is the owner of reddit site. I doubt anyone here will be able to help you. Maybe buying another unit (which you’ll return afterwards) is the best way to test yours out in a side by side comparison. I have two Boom2 units which I use in a stereo pair that offer acceptable bass. maybe you’re expecting to much from this speaker.
