Built around a 120mm woofer and dual mid‑high drivers, the EPICBOOM delivers room‑filling, 360-degree sound with punchy bass and confident high‑volume clarity. Reviewers including What Hi‑Fi? and ecoustics praise its party-scale performance; versatile PartyUp pairing, USB‑C charging and a 17‑hour battery make it a reliable outdoor companion.

Cons
- Mids can sound slightly artificial and less tonally rich than some rivals, reducing musical nuance for critical listening.
- Battery life (17 hours) is decent but outpaced by a few competing models that offer longer run times.

Bass
88/100
Reviewers note a 'decent degree of sonic punch' and broad low-end impact from the 120mm woofer; performs strongly for a portable speaker and suits party/hip-hop material.
Mid
80/100
Mids are serviceable but can sound slightly 'artificial' or less rich compared with rivals (What Hi‑Fi cites reduced tonality versus the Sonos Move 2), so vocals and timbre lack some body.
Treble
81/100
Treble is reasonably extended and holds up at loud levels, though Outdoor Mode can make it a bit harsher/industrial-sounding per the review; minimal obvious distortion at high volumes.
Soundstage Imaging
86/100
360-degree driver arrangement and reviewer comments about a 'broad, expansive sound' give this speaker unusually wide coverage and a confident omnidirectional presentation.
Dynamics
83/100
Shows robust macro dynamics and clean output at high volumes ('considerable lungs' and little obvious distortion), though it's not the most rhythmically sprightly speaker versus some competitors.
Show Less
Build Quality
90/100
Described as 'burly', well-made and likeable; IP67 rating and solid construction give a premium, robust feel for portable use.
Features Connectivity
80/100
Passive baseline applied.
Value for Money
80/100
At ~$329 the Epicboom is seen as earning its high-end price tag with strong features and performance, though battery life is only 'okay' and some rivals offer greater tonal refinement.
