Ultimate Ears BOOM 3chat_bubble_outlineFrom real comments

Built like a tank, but not indestructible. Multiple users describe extreme durability, including surviving a forklift run-over, being abandoned outdoors covered in dirt, and even surviving a hurricane while still functioning. One user ran it over with a forklift and it still worked. Another praised its toughness after two years of heavy daily skateboarding use. However, some users report their units failing entirely after drops or water incidents, showing durability isn't universal.

Loud sound but bass falls short of the Megaboom. Users say the BOOM 3 fills big spaces well and delivers low distortion audio, with one describing custom EQ settings producing thundering bass. However, several commenters note the stock bass is merely adequate, with one choosing the Megaboom instead due to lacking bass in-store. Sound quality issues also appear at high volume, with reports of noise and distortion past certain volume thresholds.

Waterproofing and charging reliability are inconsistent. While some users happily use the speaker in the shower with no issues, others report Bluetooth cutting out when partially submerged or complete failure after pool drops. Charging complaints are frequent, including units that won't charge, missing power adapters with no specs provided, and requests for USB-C in future models. Several users also report full battery drain issues or dead units requiring multiple replacements.
