Pros: Removable battery. Quite deep bass, reaching well below 40Hz. A fantastic sounding speaker with excellent off-axis dispersion, a big step up from older JBL portables. Beats the Soundcore Boom 2 and Tribit Stormbox Blast on bass depth and clarity. Plays clean at volume, unlike the JBL Boombox 4.

Cons: High priced. Some bass boost. A hole in the mid-upper bass which can’t be EQ’d out. Default EQ presets are weak (Signature is boring, Chill and Vocal are close to unusable) - needs the custom EQ to sound its best. Bigger and heavier than the Xtreme 4.

Setup: Try this Oluv EQ for the most neutral sound
