The Samsung HW-C400 is a compact 2.0-channel budget soundbar with a built-in woofer that Samsung launched in 2023 to replace weak television (TV) speakers, and in 2026 it’s worth buying only at a clearance or refurbished price. It was the cheapest soundbar in Samsung’s lineup, it skips High-Definition Multimedia Interface (HDMI) ports, Wi-Fi, and Dolby Atmos, and it typically sold for around $100 to $130. This Samsung C400 soundbar review explains what the C400 does well, where reviewers and owners say it falls short, what replaced it in 2025, and which budget soundbars on Amazon deserve a look before you buy.
Quick verdict: The Samsung C400 delivers clear dialogue and a tidy, simple setup for a small TV in a bedroom, dorm, or office. It doesn’t move much air, its bass stays modest, and it connects only by optical cable or Bluetooth. Samsung has since replaced it with the 2025 HW-B400F, so buy the C400 only at a clearance or refurbished price. Check the Samsung C400 price on Amazon.
Key takeaways
- What it is: A compact 2.0-channel soundbar with a built-in woofer that Samsung launched in 2023 as the cheapest bar in its lineup.
- Who it’s for: Small TVs in bedrooms, dorms, kitchens, or offices, where clear dialogue matters more than deep bass.
- Price: It typically sold for around $100 to $130, and leftover, open-box, and refurbished units still turn up (fall 2026). Prices change often.
- Main weaknesses: Modest bass, limited volume for larger rooms, and no HDMI Audio Return Channel (ARC), Wi-Fi, or subwoofer support.
- Successor: Samsung replaced it with the 2025 HW-B400F, which keeps the same 2.0-channel, built-in-woofer design.

Is the Samsung C400 still available?
Not new from Samsung. Samsung’s U.S. and Canadian product pages list the HW-C400 as out of stock, and the Canadian page points shoppers to the newer HW-B400F, a 2025 model with the same 2.0-channel, built-in-woofer formula. Samsung lists the B400F at $139.99. You can still find the C400 as leftover stock, open-box, or refurbished units at retailers such as Best Buy, Amazon, and Walmart. Prices change often, so compare the C400’s price against the B400F before you buy.
Design and build
The C400 measures about 25 inches wide, so it suits TVs from roughly 32 to 50 inches without looking lost. A black plastic body and wraparound mesh grille keep it understated, though the fabric collects dust. It weighs only about 2 pounds, and StereoIndex notes that Samsung includes wall-mounting brackets in the box.
Instead of a text display, the C400 uses a light-emitting diode (LED) status indicator that changes color and blinks to show the input and settings. Owners and reviewers say that system takes some getting used to, and you’ll probably keep the manual handy for the first few weeks. If you place the bar on a stand, leave a few inches between the stand and the bottom of your screen so the bar doesn’t block the TV’s infrared sensor.
Connectivity and setup
The C400 keeps connections minimal. You get one optical input, Bluetooth, and a USB-A port that plays common music files from a flash drive. It has no HDMI ARC port, no Wi-Fi, no app support, and no 3.5-millimeter auxiliary input.
- Optical: The most reliable option. Run the included optical cable from your TV to the soundbar, then choose the soundbar or optical output in your TV’s sound settings.
- Bluetooth TV Connection: Recent Samsung TVs and some other Bluetooth TVs can send audio wirelessly, which removes the cable. Owners report occasional lip-sync delay over Bluetooth, so optical works better for movies.
- Phones and tablets: Tap an NFC-capable Android phone on the top panel to pair, or pair through your device’s Bluetooth menu. Samsung lists only the basic Subband Coding (SBC) Bluetooth codec.
Because the C400 lacks HDMI Consumer Electronics Control (CEC), your TV remote can’t always control it automatically. Samsung’s One Remote feature fixes most of that: you can teach the soundbar to respond to the volume buttons on remotes from Samsung, LG, Sony, Vizio, Hisense, Panasonic, Philips, and several other brands. Samsung’s Auto Power Link also turns the bar on with your TV over optical. If your TV lacks an optical output, an HDMI ARC to optical audio converter solves the problem for about $20.
Sound modes and features
Samsung gives the C400 four listening modes. Standard plays audio as recorded. Surround Sound Expansion widens the soundstage with processing, though it can’t create real surround or height channels from a two-channel bar. Voice Enhance lifts dialogue, and Night Mode reduces loud peaks so explosions don’t wake the house. The bar decodes Dolby Digital and DTS signals as two-channel audio. It doesn’t support Dolby Atmos, DTS:X, Samsung’s Q-Symphony, or SpaceFit room calibration.
Sound quality: what reviewers found
Reviewers agree that the C400 is a clear improvement over the thin speakers in most budget TVs, especially for speech. StereoIndex praised its clear, focused dialogue, decent stereo separation, solid midrange, and well-defined treble, and it noted that the bar doesn’t distort at maximum volume.
The same review also flagged the C400’s limits. It found the bass lacking for action movies and games, the soundstage fairly narrow, and Surround Sound Expansion only mildly effective. The reviewer also said the bar is “definitely not loud,” which makes it a poor fit for big, open living rooms. Owner feedback summarized by ShopSavvy lines up with that: buyers like the dialogue clarity, compact size, and easy setup, but some want deeper bass and more volume. Because the C400 can’t pair with a subwoofer, you can’t fix the bass later. If low end matters to you, step up to a 2.1-channel model with a subwoofer.

- Samsung HW-B400F: The newest version of this same idea, with Bluetooth TV Connection, Surround Sound Expansion, and One Remote support. Buy it if the C400 costs nearly as much. See the Samsung B400F on Amazon.
- Bose Solo Soundbar Series II: Bose’s small TV speaker focuses on speech clarity and costs a bit more. Read our Bose Solo Soundbar 2 review for the details. See the Bose Solo on Amazon.
- Roku Streambar SE: It adds a 4K high dynamic range (HDR) Roku streaming player to a compact bar and connects over HDMI ARC, so it suits older TVs with slow smart platforms, according to Roku’s spec page.
- Vizio V21-H8 and Samsung B550F: Both include a subwoofer, which fixes the C400’s biggest weakness. Tom’s Guide names the Vizio its best-value cheap soundbar for its deep bass.
Who should buy the Samsung C400?
The C400 makes sense for a secondary TV in a bedroom, kitchen, dorm, or home office, where clear voices matter more than room-shaking bass. It pairs well with budget sets such as the Samsung CU7000 and the picks in our best 55-inch TVs under $500 guide, especially in smaller rooms. Check our bedroom TV size guide if you’re setting up a compact space. Skip the C400 if you watch a lot of action movies, want HDMI ARC control, or plan to fill a large living room. A 2.1-channel bar with a subwoofer will serve you better there.
Frequently asked questions
Does the Samsung C400 have HDMI?
No, the Samsung C400 doesn’t have HDMI. It connects to your TV only through its optical input or Bluetooth. It has a USB-A port, but only for playing music files.
Can you add a subwoofer to the Samsung C400?
No, you can’t add a subwoofer to the Samsung C400. It has a built-in woofer but no subwoofer output or wireless subwoofer pairing. Choose a 2.1-channel model like the Samsung HW-B550F or Vizio V21-H8 if you want more bass.
Does the Samsung C400 work with non-Samsung TVs?
Yes, the Samsung C400 works with non-Samsung TVs. It works with any TV that has an optical output or Bluetooth audio, and its One Remote feature lets you control volume with remotes from many major TV brands.
What replaced the Samsung C400?
Samsung’s 2025 HW-B400F replaced the Samsung C400. The B400F keeps the 2.0-channel, built-in-woofer design and lists for $139.99 at Samsung.
Final verdict
The Samsung C400 does the basics well: it makes dialogue easier to hear, sets up in minutes, and takes up little space. Its modest bass, limited volume, lack of HDMI ARC, and discontinued status keep it from being an easy recommendation at full price. Grab one at a clearance or refurbished price for a small room, or step up to the HW-B400F or a 2.1-channel bar if you can spend a little more. Check the current Samsung C400 price on Amazon.
