Who wins on what

Ranked by what users actually praise

Overall Impression

Bass and loudness are the standout traits, particularly when powered. Multiple users describe the speaker as extremely bass-heavy and loud, with one noting a 'hugeeee difference' plugged in versus on battery, and another saying it 'booms some serious bass' throughout a house. Some found the bass overwhelming or headache-inducing even after EQ adjustments, while others felt it wasn't as boomy as older Onyx models, showing sound tuning varies by unit or generation.

Battery life and power reliability draw frequent complaints. Several commenters report short runtimes, such as only 2-4 hours at moderate volume or 30 minutes when unplugged before failure. Others describe units that stop turning on entirely after about a year, or that must stay plugged in for full volume, calling this frustrating and a dealbreaker for portable use compared to what they expected from the price point.

Bluetooth pairing and stereo linking are inconsistent for many owners. Users describe Bluetooth as extremely difficult to connect, sometimes working and sometimes not despite repeated button presses. Owners of two units for stereo pairing say the pair never automatically resumes stereo mode after reconnecting, forcing manual resyncing each time, and one notes the companion app doesn't even recognize the speakers, adding extra friction to a feature that should be simple.
