THE QUICK TAKE
Is it right for you?
Go 4 is a good fit for podcasts and casual music close by. It is easy to move between rooms or tuck into a bag, and physical buttons spare you a phone unlock for every volume change.
Choose a larger speaker for deep bass or music across a gathering. RTINGS found the small size limits bass and maximum output. The newer Go 5 is also worth comparing if the price gap is small.

02 / AMAZON REVIEWS
The buyers’ view.
Owners of the black Go 4 appreciate its small, portable shape. One reports quick Bluetooth pairing and useful app EQ, but finds bass limited; another enjoys its thunder playback for rain sounds while noticing occasional muffled audio.
Battery management drew mixed experiences: one owner likes checking charge in the app, while another struggled to judge the remaining charge and sometimes had playback stop unexpectedly.

What the sources say.
The speaker reproduced voice clearly enough for podcasts, but its size limited bass and loudness. The app EQ does not remove those physical limits.
The regular runtime claim differs from Playtime Boost, which adjusts the sound. The USB-C connection is for charging on this generation.
