43% recommend · 19% neutral · 38% don't
Owners praise
  • Paired in stereo mode, two units deliver noticeably better separation and fuller sound than a single speaker
  • Surprisingly punchy, warm bass and full-bodied sound for such a compact, portable size
  • Strong value at typical sale prices ($25-$100), often called a steal for the sound quality delivered
Owners complain about
  • A firmware update added a jarring, loud startup/shutdown chime with no way to disable or lower its volume, repeatedly startling owners and waking people at night
  • Recent firmware updates stripped away features many relied on, including voice battery announcements, cycling Bluetooth sources via the button, and stable stereo pairing/connections
  • Battery drains even while powered off and degrades within 1-2 years, sometimes failing to hold a charge at all
