Buying Guide: What to Look for in Soundbars with Multiple HDMI Inputs

Number of HDMI Inputs

Most soundbars today feature a single HDMI ARC or eARC port. This allows audio to flow from your TV to the bar, but it limits how many source devices you can connect directly. If you need to plug in a game console, a streaming device, and a cable box, you will want a soundbar with at least two HDMI inputs. Alternatively, you can use an HDMI splitter like the avedio links HDMI Splitter 1 in 2 Out to duplicate one signal to multiple displays, or a switcher to toggle between sources. For a deeper dive into smart features, see our best smart soundbars guide.

Audio Performance and Formats

Great sound matters as much as connectivity. Look for soundbars that support Dolby Atmos and DTS:X for immersive, room-filling audio. The TCL S45H 2.0 Sound Bar delivers Dolby Atmos and DTS Virtual:X with AI room calibration. The Bose TV Speaker (2nd Gen) focuses on clear dialogue with proprietary Dialogue Mode. If you want deep bass without a separate subwoofer, the BESTISAN 2.1ch Sound Bar includes a built-in subwoofer. For wireless options, browse our best wireless soundbars.

Connectivity Options Beyond HDMI

Even with limited HDMI inputs, you can still connect many devices via optical, AUX, USB, or Bluetooth. The BESTISAN soundbar offers Bluetooth 5.3, ARC, optical, AUX, and USB. The TCL S45H includes HDMI eARC/ARC, optical, Bluetooth, and AUX. The Bose TV Speaker has HDMI-ARC and Bluetooth. If you need more HDMI ports, the avedio links splitter adds two outputs from one source. For Alexa integration, see our best soundbars with alexa recommendations.

Size and Design

Soundbars come in various widths to fit your TV setup. The TCL S45H measures 31.89 inches wide, ideal for 40-inch and larger TVs. The Bose TV Speaker is compact at just over 2 inches tall, fitting neatly under any screen. The BESTISAN is only 16.5 inches wide, perfect for smaller desks or monitors. Consider the physical space and whether you prefer a low-profile design. For more size comparisons, visit our Soundbars category page.

Final Thoughts

After evaluating these products, our top recommendation for a soundbar with flexible connectivity is the TCL S45H 2.0 Sound Bar for its Dolby Atmos support, AI room calibration, and multiple connection options. If you prioritize crystal-clear dialogue and a premium brand, the Bose TV Speaker (2nd Gen) delivers exceptional vocal clarity and a simple setup. To add extra HDMI inputs to either soundbar, pair them with the avedio links HDMI Splitter. For a budget-friendly all-in-one with built-in subwoofer, the BESTISAN 2.1ch soundbar offers great value. Choose based on your room size, audio preferences, and how many devices you need to connect.

Frequently Asked Questions

How can I connect multiple HDMI devices to a soundbar with only one HDMI input?

Use an HDMI switch or splitter. An HDMI switch lets you toggle between multiple source devices and send one signal to your soundbar. The avedio links splitter duplicates one input to two outputs, ideal for mirroring a single source to a TV and soundbar. For more tips, see our best WiFi soundbars guide for alternative wireless connections.

Do soundbars with multiple HDMI inputs support 4K and HDR?

Yes, many modern soundbars with HDMI 2.0 or 2.1 inputs support 4K@60Hz and HDR pass-through. The TCL S45H and Bose TV Speaker support HDMI ARC and eARC, which can handle 4K signals from your TV. The avedio links splitter supports 4K@30Hz, so it works for most content.

What is the difference between HDMI ARC and HDMI eARC?

HDMI ARC (Audio Return Channel) lets audio travel from your TV to the soundbar through a single HDMI cable. HDMI eARC (enhanced ARC) supports higher bandwidth audio formats like Dolby Atmos TrueHD and DTS:X. The TCL S45H includes eARC for the best audio quality. The Bose TV Speaker uses standard ARC, which is sufficient for compressed Dolby Atmos.

Can I use an optical cable instead of HDMI for multiple inputs?

Yes, optical cables carry compressed 5.1 surround sound but cannot transmit Dolby Atmos or DTS:X. If your soundbar has optical input, you can connect a TV or a device with optical output. However, HDMI is recommended for the best audio quality and to support multiple inputs via a switch. For more information, check our best wireless soundbars for Bluetooth alternatives.
