Its 11.7″ length fits under most screens, making it ideal for bedrooms or small living rooms. It offers optical input alongside Bluetooth and 3.5mm AUX, plus a dedicated sub out for a powered subwoofer to boost bass when desired. Choose this if you need a space-saving bar without sacrificing clarity or mid/high detail.
Who it’s for: TV watchers in tight spaces who want better sound without a bulky soundbar. Why selected: strongest combination of compact design and an optical input at this size. Caution: bass may feel lean without a subwoofer in very large rooms.
Assistrust Sound Bar for Smart TV

It spreads sound across the room to create a more immersive experience and emphasizes balanced playback with clear dialogue.

It supports Bluetooth and HDMI-ARC, delivering simple setup and straightforward control with compatible TVs. Choose this if your priority is crisp vocal clarity and a minimal setup. Caution: optical input is not specified in the listed features; confirm available inputs if optical is required.

Best for mid-sized rooms seeking a larger visual footprint with enhanced dialogue, this 17″ sound bar highlights DSP processing and three sound modes to optimize movies, music, or news. It offers a compact height that fits most TV stands and wall mounting possibilities. The data does not confirm an optical input, so check compatibility if you must have optical connectivity. Choose this for a noticeable upgrade in room-filling sound without a separate speaker system.
Buying Guide: Optical Input Sound Bars
What matters most for optical input sound bars is how you balance input flexibility, room size, and content type. Here are practical considerations to help you decide:
- Input options: If optical input is essential, confirm that the model explicitly lists Optical In in its specifications. Some models rely on HDMI-ARC or Bluetooth for TV audio.
- Room size: Smaller rooms benefit from compact bars with efficient digital signal processing. Larger spaces may need higher power or a subwoofer for full-range sound.
- Dialogue clarity: Look for bars with dedicated dialogue modes or drivers designed to emphasize midrange frequencies where human speech resides.
- Placement and design: Wall-mountable or compact bars reduce obstruction and keep the TV center aligned with the speaker array.
- Subwoofer options: A separate subwoofer can dramatically improve bass for movies and music, especially in open-plan spaces.
- Smart features and controls: Remote compatibility, TV-brand integration, and EQ presets can simplify daily use.
