Top complaints
Samsung HW-Q990H
- Pricey, wide, and a modest subwoofer
Wirecutter calls it pricey and says the 48.5-inch bar may not fit between a TV's legs. Its compact sub measured 5.6 dB (mid-bass) and 4.2 dB (low-bass) less than the Vizio Elevate's and isn't likely to shake your couch. A 2-star Amazon reviewer found the sub basically useless.
- Annoying display and app-dependent controls
Wirecutter says the front display scrolls only four characters at a time, so you end up using the SmartThings app, which takes more time than grabbing a remote.
Source: Wirecutter (NYT) - Little gain over the cheaper HW-Q990F
RTINGS found much of the performance unchanged from the HW-Q990F. It says the new Sound Elevation feature lifts dialogue at the cost of horizontal clarity, and it picks the discounted Q990F as the better value. A few early Amazon reviewers were disappointed with the sound and soundstage.
TCL S55H
- Dropouts and subwoofer failures
Low-star Walmart reviews describe an HDMI connection that drops regularly (Oct 2026), a sub that's hard to connect to the bar, a subwoofer that stopped working after re-pairing and resets, and a bar that developed a doubled, reverb-like sound after a few months.
Source: Walmart reviews (lowest rated) - Limited volume and envelopment
Wirecutter says it can't match the volume and envelopment of pricier soundbars. RTINGS says it plays only stereo, with some compression at max volume. A few Walmart owners say it isn't loud and they can't hear the bass.
- Confusing tone controls, few connections
Wirecutter had to stand up to read the bass and treble indicator on top of the bar. There are no HDMI inputs and no Wi-Fi, and the app's AI Sonic room tuning made little audible difference.
