AI Verdict
This compact 2.0-channel soundbar is a cheap, dead-simple fix for muffled TV dialogue in small bedrooms, but bass-heads should look elsewhere.
With only 40 watts of power and no external subwoofer, this won't deliver a home theater experience. It excels purely as a low-profile dialogue booster for small spaces where you cannot fit extra gear.
If you want actual bass for movies, step up to a 2.1 channel system that includes a dedicated wireless subwoofer.

Chance this product isn't for you
Pros
- Voice Enhance mode pushes dialogue forward, making quiet movie whispers legible.
- At 25.2 inches wide and 2.6 inches tall, it slides under almost any TV without blocking the screen.
- HDMI ARC support means your existing TV remote controls the volume and power.
- Built-in NFC allows instant Bluetooth pairing with your phone just by tapping it.
- Night Mode cuts low frequencies so you won't wake up people in the next room.
Cons
- The LED status lights sit on the top panel, making them impossible to see from the couch.
- No dedicated subwoofer means action movie explosions and heavy bass tracks sound flat.
- Lacks Wi-Fi, Apple AirPlay, and smart assistant support entirely.
- The fabric grill covering the speakers acts as a magnet for dust and pet hair.
Dimension Scores
Dialogue is crisp thanks to the dedicated front-firing tweeters, but the overall soundstage is narrow.
The built-in woofer struggles with sub-bass frequencies, and 40W max output won't fill a large room.
Includes HDMI ARC, Optical, and NFC Bluetooth, but lacks Wi-Fi and a 3.5mm jack.
At 4.6 pounds and 25 inches wide, it is easy to move, though the fabric grill feels cheap.
Best For
- Small bedroom or dorm setups where a separate subwoofer box won't fit.
- Older relatives who just want to hear the news without dealing with a complicated receiver.
- Secondary TVs used mostly for YouTube, podcasts, or sitcoms.
Not Recommended For
- Large living rooms that need room-filling cinematic sound.
- Gamers or action movie fans who want chest-thumping bass.
Watch Out For
- The status LEDs sit on top of the bar and use confusing color codes instead of a text display, so you constantly guess what mode you selected.
- There is no 3.5mm aux input, so you cannot plug in older analog audio devices.
- Bluetooth connection occasionally drops if you don't use HDMI ARC for your main TV connection.
- It lacks support for the Samsung SmartThings app, meaning you rely entirely on the physical remote for EQ tweaks.

What Buyers Say
Buyers grab this specifically to fix terrible built-in TV speakers, and it handles that job perfectly. The biggest recurring complaint is the bizarre placement of the LED indicator lights on the top panel, which forces you to stand up to see what input you selected. Reviewers constantly praise the Voice Enhance mode for late-night Netflix binges. Anyone expecting cinematic rumble is quickly disappointed by the 40W output and lack of a real subwoofer.
“Finally I can hear what people are saying on Netflix without turning it up to 50, but I hate that I have to memorize what the blinking colored lights on top mean.”
Common Praise
- Voice Enhance mode makes mumbled dialogue crystal clear.
- Fits perfectly between the legs of most 43-inch to 55-inch TVs.
- HDMI ARC setup takes less than two minutes.
- NFC tap-to-pair makes playing Spotify from a phone effortless.
Common Complaints
- Top-mounted LED lights are invisible from the couch.
- Fabric covering collects dust and is hard to clean.
- Bass is virtually non-existent for action sequences.
- No visual display to show the actual volume number.
Ownership Tips
- The fabric mesh requires regular vacuuming or lint-rolling to keep it looking clean.
- Bluetooth occasionally requires a manual power cycle to reconnect to the TV.
- Night mode is a lifesaver for apartment living, as it aggressively kills the low-end frequencies.
Frequently Asked Questions
Does it come with an HDMI cable?
No, Samsung only includes the power cable and remote in the box. You need to buy your own HDMI or optical cable.
Can I control the volume with my Roku or Apple TV remote?
Yes. Connect the soundbar to your TV's HDMI ARC port, and your streaming remote will control the volume via CEC.
Can I add wireless rear speakers to this later?
No. The HW-B400F is a standalone 2.0 system and does not support Samsung's wireless rear speaker kits.
Does it have a headphone jack?
There is no 3.5mm input or output on this model. It only accepts HDMI ARC, Optical, USB, and Bluetooth.
How do I know if it's on or what input is selected?
Small LED lights on the top right edge change color based on the input. They are very hard to see from a normal seating position.
Buying Guide
When buying a budget soundbar, you are essentially just buying larger, forward-facing versions of your TV's speakers. Without a separate subwoofer box, you will not get the deep rumble you feel in a movie theater. Your main goal here is dialogue clarity and volume. Always use the HDMI ARC connection if your TV has it, as this lets you use your normal TV remote for volume instead of juggling two remotes.
2.0 Channels
This means there is a left and right speaker, but no dedicated center channel for voices and no separate subwoofer for bass. It is a basic stereo setup.
HDMI ARC
Audio Return Channel lets your TV send sound down the HDMI cable to the bar, and lets your TV remote control the soundbar's volume.
40W Output Power
This is the maximum volume the bar can push. 40 watts is plenty for a bedroom, but will sound weak in an open-concept living room.
Alternatives
If you want actual bass for movies, search for a 2.1 channel soundbar with a wireless subwoofer. If you want immersive surround sound, look for Dolby Atmos soundbars with upward-firing speakers.
