Your TV’s built-in speakers are fighting a losing battle. As screens have gotten slimmer, speaker space has shrunk — and many modern TVs push audio out from the bottom or rear of the panel, which is about as useful as it sounds. A soundbar fixes this without rewiring anything or spending serious money. Under $100, you won’t get a cinematic surround setup, but you will hear dialogue more clearly, get noticeably more volume, and have Bluetooth for music — and that’s what most people actually need.
Our top choice at this price is the Roku Streambar SE (~$99, often on sale for less), which bundles a clear-sounding bar with a full 4K HDR Roku streaming device — one cable replaces both your streaming stick and your TV’s tinny audio. If you just want the best straight TV audio upgrade without the streaming bonus, the TCL S45H (~$79–$99) offers Dolby Atmos processing and HDMI eARC at a price that’s hard to argue with. For desk use or small bedroom setups, the Creative Stage Air V2 (~$49–$55) is portable, battery-powered, and punches well above its size. Prices verified as of March 2026 — check current listings, since these models go on sale regularly.
Is a Sub-$100 Soundbar Worth It for You?
✅ Buy One If:
- You want clearer TV dialogue without spending $200+
- Your TV is in a bedroom, apartment, or secondary room
- You mainly watch shows, sports, or streamed movies
- You want Bluetooth music playback from your phone
- This is your first soundbar and you want to test the category
❌ Skip and Spend More If:
- You’re setting up a large living room home theater
- You want actual Dolby Atmos height effects (those need up-firing speakers, found at $200+)
- You have multiple HDMI sources to connect directly to the bar
- Music accuracy matters — these bars are built for TV, not critical listening
Our Top Picks: Best Soundbars Under $100
Best Overall — Roku Streambar SE (~$99)
The Roku Streambar SE earns its spot at the top because it does something none of the other bars here can: it replaces two devices with one. You get a genuinely decent-sounding 2.0-channel bar and a full Roku 4K HDR streaming platform in a 9.6-inch unit that connects with a single HDMI cable. According to Wirecutter’s January 2026 review, it “offers a clear upgrade from the sound of most TV speakers” with “excellent dialogue clarity.” For anyone who still uses their TV’s built-in smart platform or a separate streaming stick, this is an easy swap that pays off on two fronts.
The MSRP is $99.99, but it frequently drops to $70–$80 on Amazon — check current pricing before buying. It connects via HDMI ARC or optical, and the Roku remote handles volume control so you don’t need to juggle multiple controllers. The Enhanced Speech Clarity mode is a real feature, not just a marketing label — it does meaningfully sharpen dialogue on talk-heavy programming.
Best for: Cord-cutters upgrading a bedroom or secondary TV
Watch out for: No separate subwoofer, so bass is light on action-heavy content

Best Pure TV Upgrade — TCL S45H (~$79–$99)
If you don’t need a streaming device bundled in, the TCL S45H is the most capable 2.0-channel speaker bar you can pick up for the money. It ships with Dolby Atmos and DTS Virtual:X processing, HDMI eARC (so your TV remote controls the volume via CEC), Bluetooth 5.2, and an AI Sonic Auto Room Calibration feature that tunes the output to your space. Best Buy lists it at $99.99 (down from $129.99), while TCL’s official store sells it for $79.99 as of March 2026. Either way, it’s a lot of soundbar for the price.
One realistic note: the Dolby Atmos here is virtual processing, not true overhead audio. You won’t get height effects from up-firing speakers at this price — what you get is a wider, more spacious stereo image, which is still a genuine improvement over flat TV audio. The six EQ modes (Movie, Music, Voice, Game, Sports, Standard) let you fine-tune to the content you’re watching.
Best for: First-time soundbar buyers wanting a clean HDMI eARC connection
Watch out for: No Wi-Fi streaming (Bluetooth only for music); no subwoofer
Best for Desks and Small Rooms — Creative Stage Air V2 (~$49–$55)
The Creative Stage Air V2 occupies a different niche than the other bars here. At 16.1 inches wide, it’s designed to sit under a monitor rather than a TV — though it works just as well beneath a 32″–40″ screen. Creative’s official specs show two 5W RMS full-range drivers (10W total), Bluetooth 5.3, USB-C audio input, a 3.5mm aux jack, and a 2,200mAh battery that delivers up to 6 hours of wireless playback. At $54.99 direct (often ~$49 on Amazon), it’s one of the few portable soundbars worth taking seriously.
The battery is what makes it genuinely useful. You can move it from desk to bedroom to kitchen without hunting for power outlets. It won’t shake the walls, but for a small space — dorm room, home office, bedroom with a smaller TV — the clarity and volume are a meaningful step up from what’s built into a laptop or monitor. Multiple independent reviewers noted it “blows your default speakers out of the water” for the price.

Best for: PC gaming audio, desk setups, dorm rooms, portable use
Watch out for: No HDMI ARC; not ideal for living room TVs larger than 40″
Best Under $40 — Insignia 2.0 Mini Soundbar 20″
The Insignia 20″ mini bar (NS-SB20S) is Best Buy’s house-brand entry-level pick, and for around $40 — sometimes as low as $25 during sales — it’s a reasonable first step for anyone with a smaller TV. It measures 20 inches wide, includes a remote, Bluetooth, USB input, and optical connectivity. With over 337 five-star ratings at Best Buy as of March 2026, the real-world feedback is consistently positive for its price tier.
Don’t expect Dolby processing or advanced connectivity. This is a “louder and clearer than nothing” buy — which is often exactly what a 32″ bedroom TV needs. Use it for a TV that sees mostly news, talk shows, and casual streaming.
Best for: 32″–40″ TVs in smaller rooms; budget buyers trying soundbars for the first time
Watch out for: No HDMI ARC; basic 2.0 sound only
Best for Bass — Insignia 2.1 with Wireless Subwoofer (~$99)
If you want some actual low-end weight from a sub-$100 purchase, the Insignia 2.1 bundle is the one to look at. It pairs a Bluetooth soundbar with a separate wireless subwoofer, adds DTS Virtual:X surround processing, and includes a dialogue enhancement mode — all for $99.99 at Best Buy. With 180 reviews averaging 4 stars, the consensus is that the subwoofer makes a real difference for movie nights, even if the overall setup is basic compared to mid-range bars.
The trade-off is that DTS Virtual:X is simulated surround, not true multichannel audio, and the wireless sub connection can introduce occasional latency on some setups. For most uses, though, it works well out of the box.
Best for: Movie watchers who want bass without spending $150+
Watch out for: Wireless subwoofer can occasionally drop sync; DTS Virtual:X is not true surround

What to Expect (and Not Expect) Under $100
The Honest Audio Reality Check
Every bar on this list will improve your TV’s sound. That’s not marketing copy — as What Hi-Fi noted in their 2026 budget roundup, even a basic audio bar “will absolutely smash most TVs for audio quality” by delivering more detail, punch, and volume. The gap between TV speakers and any external speaker bar is significant, particularly for dialogue clarity.
What you won’t get: true Dolby Atmos with height effects. Any bar listing “Dolby Atmos” under $100 is using virtual processing — it creates a wider soundstage but no actual overhead audio. That requires dedicated up-firing drivers, which start appearing around $150–$200. For movies and shows, the virtual processing is still a meaningful upgrade; just don’t expect theater-style immersion.
If you’re ready to step up to a full home theater setup, our soundbar buying guide covers every budget tier.
Connecting Your Soundbar: HDMI ARC vs. Optical
Most people connect a soundbar once and never think about it again — but the connection type affects what audio formats you can receive. HDMI ARC is the better choice when available. It lets your TV remote control the soundbar’s volume via HDMI CEC, and it supports higher-quality audio formats. HDMI eARC (found on the TCL S45H) is an upgrade from basic ARC that can pass lossless Dolby Atmos.
Optical works on almost every TV made in the last 15 years, making it a reliable fallback. The limitation: optical is capped at compressed Dolby Digital 5.1 and cannot pass Dolby Atmos or DTS:X. For a sub-$100 bar, this rarely matters — but if your TCL S45H supports eARC and your TV does too, use HDMI.
What Size Soundbar Fits Your TV?
A rough guide based on TV screen size:
- 32″ TV: A 20″–24″ bar fits neatly — try the Insignia Mini or Creative Stage Air V2
- 40″–50″ TV: A 28″–36″ bar works well — Roku Streambar SE (9.6″) is compact but fine; TCL S45H at 31.9″ is a natural fit
- 55″–65″ TV: You’ll want 36″–45″ of bar length for visual and sonic balance — consider stepping up above $100 at this size
A bar noticeably narrower than your TV’s base can look a bit odd, but sound-wise it still works. A bar wider than the TV’s base can look cluttered. Aim for visual parity when possible.
Who Gets the Most Out of a Sub-$100 Soundbar
✅ Strong Use Cases:
- Bedroom TV upgrade: No need for big sound — a compact bar provides enough volume and clarity for one or two people
- Apartment living: You probably don’t need room-shaking bass; a clean 2.0 bar is plenty
- Parents’ TV: Dialogue clarity is often the #1 complaint; even a $40 bar addresses this
- PC and desk setup: The Creative Stage Air V2 makes monitor speakers obsolete for the price
- First upgrade: Try a sub-$100 bar before committing to a $200+ system
❌ You’ll Likely Feel Limited:
- Large open living rooms: 10W–100W bars struggle to fill large spaces; you’ll want 200W+ for rooms over 400 sq ft
- Action movie enthusiasts: The bass on 2.0 bars at this price is workable but won’t physically impact you the way a dedicated sub does
- Multi-source setups: One HDMI ARC port is the standard here; if you have a Blu-ray player, gaming console, and streaming stick, things get messy
Frequently Asked Questions
What is the best soundbar under $100?
The Roku Streambar SE (~$99) is the top pick for most people — it improves TV audio and adds 4K streaming in one device. For pure sound quality at this price, the TCL S45H ($79.99–$99.99) is the strongest 2.0-channel option, with Dolby Atmos processing and HDMI eARC connectivity. For a full breakdown of what to look for when buying any soundbar, see our buying guide section.
Are cheap soundbars actually worth it?
Yes, for most situations. Even a $40 soundbar beats built-in TV speakers for dialogue clarity and volume — the gap is significant because modern slim TVs have very little physical room for decent speakers. You won’t replicate a home theater, but you’ll immediately notice the improvement.
Do soundbars under $100 support Dolby Atmos?
Some do, technically. The TCL S45H lists Dolby Atmos support, but at this price range it’s virtual processing — the soundbar creates a wider stereo image, not true overhead audio. Genuine Dolby Atmos with height effects requires up-firing drivers, which appear in bars priced $150 and above.
Is HDMI ARC better than optical for a soundbar?
Yes. HDMI ARC lets your TV remote control the soundbar’s volume automatically, and it supports a wider range of audio formats than optical. HDMI eARC (an enhanced version, on the TCL S45H) can handle lossless Dolby Atmos. Optical is fine as a backup and works on older TVs, but use HDMI when you can.
Can I use a soundbar under $100 to play music from my phone?
Every bar on this list supports Bluetooth — pair your phone in under a minute and stream whatever you want. The Creative Stage Air V2 goes a step further with a 6-hour battery, so you can use it as a portable Bluetooth speaker around the house.
What size soundbar should I get for my TV?
Match bar length roughly to your TV’s width. For 32″–40″ TVs, a 20″–32″ bar is appropriate. For 40″–55″ TVs, aim for 30″–40″. Going noticeably narrower looks off visually, though sonically it still works. The TCL S45H at 31.9″ pairs well with 43″–55″ screens.
Do sub-$100 soundbars have a subwoofer?
Most are 2.0-channel single-piece audio bars without a separate sub. The exception here is the Insignia 2.1 with wireless subwoofer at $99.99, which adds real bass extension. The Hisense HS2100 (2.1ch, 240W) is also worth watching — it typically lists at $119.99 but frequently drops into the sub-$100 range on sale.
How hard is it to set up a budget soundbar?
Very straightforward. Most setups take under five minutes: plug in the HDMI cable (or optical), power on the bar, and your TV should detect it automatically. No apps, no accounts, no configuration required for basic use. The TCL S45H includes the HDMI cable in the box, which saves you the trouble.
Where to Buy
Prices on these bars move regularly — deals are common, especially on the Roku Streambar SE and TCL S45H. Check current pricing on Amazon and Best Buy before you buy. Both retailers offer free returns, so you can test without risk.
