Overview
Samsung designed this slim soundbar to sit under a TV and boost speech, with a woofer built into the bar. It connects by HDMI or Bluetooth, and select Samsung TVs can control it with the TV remote.
Clearer dialogue and a simple setup lift small-screen audio without a complex system. Output power is modest, and a larger room will want a bar with a separate subwoofer.
Who it's for
A viewer who struggles to hear dialogue on built-in TV speakers, with a Samsung TV that can share its remote. The size suits a bedroom shelf. Anyone chasing cinema-level bass should step up to a bar with a wireless sub.
Pros and cons
- Dialogue boost mode
- Compact and light
- HDMI and Bluetooth
- Controls through some Samsung TV remotes
- Modest output power
- No separate subwoofer
- Remote control from TV limited to select models
- Wall mount hardware not listed
Performance notes
Dialogue boost raises speech frequencies so voices stand out from music and effects. A built-in woofer shares a small cabinet with the speakers, which limits how deep the bass goes. Placing the bar at ear height and near the TV gives the clearest result.
