Samsung HW-QS90Hchat_bubble_outlineFrom real comments

Dialogue clarity and an immersive sound stage impress at least one user. One reviewer calls the HW-QS90H a spot-on movie soundbar, praising crystal clear, loud dialogue and vocals along with an immersive overall sound stage that avoids the hollow, thin, bleeding sound they associate with other brands like Sony and Bose. Another commenter confirms that using an HDMI cable rather than optical or wireless connections is key to hearing the soundbar's best performance, suggesting the audio quality is connection-dependent and rewards a wired HDMI setup for movie watching.

Bass output and the Q-Symphony feature disappoint another user. Not every commenter is impressed with the low end: one user describes the bass as horrible and says the Q-Symphony feature sounds cheap when paired with their Samsung TV. They compare it unfavorably to two Apple HomePods, which they felt delivered twice the bass output. This suggests the QS90H's bass performance may fall short of expectations for buyers hoping for powerful low-end output, especially without a physical subwoofer in some setups.

Wireless connectivity and setup prove frustrating, with regional hardware differences. Connectivity proved frustrating for at least one user, who reported that the soundbar would not connect via Bluetooth or WiFi, forcing them to rely on HDMI instead, and found the setup process awful overall. Another commenter also recommends HDMI for best sound, implying wireless connections may be less reliable. Additionally, UK buyers should note the QS90H ships as an all-in-one unit with a newer remote and no separate subwoofer included.
