If you are weighing your next purchase, this breakdown of the seven best earbuds under 100 cuts through the noise to find your perfect match based on real-world performance.
Our Picks at a Glance
How To Choose The Best Earbuds Under 100
The best pick for you hinges on one question: where will you wear them the most? A pair great for a quiet office might be useless on a noisy subway, and a pair that lasts all day might not have the secure fit you need for the gym. Identify your primary use case first, then match the specs to that need.
Battery Life: Buds vs. Case
Manufacturers love to quote the big combined number (buds plus case recharges), but the single-charge figure matters more for daily use. A pair offering 7 hours in the buds is very different from one offering 11 hours, even if both claim “30 hours total” with the case. Check both numbers so you know if you’ll be charging at your desk or surviving an entire workday untethered.
Fit and Ear Hooks
A secure fit is essential for both comfort and sound quality, as a loose earbud leaks bass and falls out during movement. Standard in-ear designs work for most people, but if you run or hit the gym, a pair with over-ear hooks provides extra stability that standard buds simply can’t match. The fit is as important as the audio quality.
Noise Cancelling vs. Noise Isolation
Active Noise Cancelling (ANC) uses microphones to electronically cancel out ambient hum, while passive isolation is just a good seal from the ear tip. True ANC is a premium feature that helps on planes and trains, but a tight-fitting passive seal can already cut a surprising amount of noise. Skip ANC if you listen mostly in quiet rooms to save money.

In‑Depth Reviews
1. EarFun Free 2S Wireless Earbuds
The budget champ that shrugs off rain and sweat better than anything else here.
The EarFun Free 2S makes its case with a single spec: IPX7 waterproofing. That rating means they can handle being submerged in water, a step up from the splash-resistant IPX4 found on the Sony WF-C510 and the JBL Tune Flex. For runners who get caught in downpours or gym-goers who drench their gear, this is the pair that keeps playing without worry.
Inside those tough shells are 7mm dynamic drivers that nearly everyone agrees punch above their weight class. The sound is bass-forward and detailed, and the companion EarFun App lets you dial in a multi-band EQ to your taste, customize touch controls, and even switch on a Game Mode for lower latency. Buyers consistently rank this among the best budget wireless earbuds, and the 30-hour total playtime (7 hours from the buds, the rest from the case) means you are rarely hunting for a charger.
The flip side is reliability over the long haul. While the sound and comfort earn near-universal praise, a smaller group reports charging contact issues that emerge after several months of use. Buyers report “Second pair; first had charging contact issues after 4-5 months,” which is worth knowing if you plan to keep them for years.
Why People Love Them
- Class-leading IPX7 waterproofing shrugs off rain and heavy sweat
- Wireless charging case is a rare convenience at this price
- Customizable EQ and controls via the EarFun app
Consider This
- Long-term charging contact issues reported by some owners
- No active noise cancelling, just a passive seal
- Connectivity and reliability get mixed feedback over time
Reach for these if: you want maximum weather protection for workouts and a customizable sound profile for a very budget-friendly price.
Look elsewhere if: you need active noise cancelling or are worried about occasional long-term charging quirks.
2. Sony WF-C510 Truly Wireless Earbuds
The marathoner of the list, with a battery that outlasts a full workday and then some.
The Sony WF-C510 leads with battery stamina. While the EarFun Free 2S gives you a single-charge run of 7 hours, the Sony buds stretch that to 11 hours—a 57% longer gap that means a full day of calls, podcasts, and music without ever putting them back in the case. A quick 5-minute charge adds up to 1 hour of playback when you are truly in a rush.
Comfort is the second pillar. Sony’s compact, light design with hybrid silicone tips earns near-universal praise for staying put without hurting the ears, even after hours of wear. The multipoint connection lets you pair with two devices at once and switch between, say, your laptop and phone without re-pairing. And DSEE boosts the quality of compressed music, giving streaming tracks a bit more life.
There is no ANC here—just an Ambient Sound Mode that pipes the outside world in when you need it. The water resistance is IPX4, which means splashes and sweat are fine, though it falls short of the EarFun’s submersible IPX7 rating. Owners mention one impressive durability anecdote: a pair that “survived a 15-min washing machine cycle, works perfectly after drying.”
All-day comfort king: 11-hour single-charge battery life is the headline, and the secure, pain-free fit makes it easy to wear them for all of it.
The honest caveat: no ANC and a splash-only IPX4 rating mean this is a quiet-space companion, not a gym or noisy-commute powerhouse.
3. Soundcore by Anker Space A40
A 50-hour total battery that turns the charging case into a weekly habit.
The Soundcore Space A40’s defining number is 50 hours—that’s the combined playtime with the charging case, and it dwarfs the Sony WF-C510’s 22-hour total by a massive margin. The buds themselves deliver 10 hours on a single charge, and a fast 10-minute charge gives you 4 more hours of listening. This is the pair you grab for a week-long trip without packing a charger.
Sound quality is where it surprises. The double-layer diaphragm drivers produce strong bass, clear mids, and bright treble, with LDAC mode for Hi-Res Audio Wireless streaming if your phone supports it. The adaptive ANC system automatically adjusts noise cancelling levels to your surroundings, and owners consistently report it rivals far more expensive flagship buds at blocking out the world.
The trade-off is the fit. While many find them comfortable enough for all-day wear, a significant number report the buds can be prone to falling out of their ears—it’s the most common complaint. The mic quality also gets mixed marks, with some noting it sounds “speakerphone-like” on calls.
The Headline Numbers
- Industry-leading 50-hour total battery life with the case
- Adaptive ANC that owners say rivals premium flagships
- Hi-Res Audio support via LDAC for better streaming quality
Watch Out For
- Fit is a roll of the dice—many find them loose and prone to falling out
- Call quality is a weak point compared to the music experience
Perfect for: frequent travelers and marathon listeners who want maximum battery and effective noise cancelling.
Not ideal for: anyone with tricky ears who needs a guaranteed rock-solid fit, or heavy phone talkers.
4. Nothing Ear (a) Wireless Earbuds
The style statement with 11mm drivers that deliver a genuinely hefty bass punch.
Nothing Ear (a) turns heads with its transparent design, but the 11mm dynamic driver is what keeps them in your ears. That larger driver, compared to the 7mm in the EarFun and 6mm in the Sony, moves more air and produces deeper, more effective bass. Owners describe the sound as crisp with impressive instrument separation, often comparing it favorably to far pricier flagships.
The 45dB Hybrid ANC is adaptive, constantly monitoring the seal in your ear canal and adjusting cancellation intensity to compensate for any leakage. It works well, though customers note it is good, not class-leading. The 6 mics, including a dedicated talk microphone, keep your voice clear on calls even in wind.
Battery life is the weak link here. While the total is a respectable 42.5 hours with the case (ANC off), the buds themselves only manage a few hours with ANC engaged—a 3-4 hour run is the common complaint. That is shorter than the Sony’s 11-hour single charge and a real consideration if you rarely take them out. The pinch controls on the stem also take some getting used to.
Sound and style: Big, punchy 11mm drivers and a unique look make these the most distinctive-feeling earbuds on the list.
Reality check: ANC eats the battery fast—expect 3-4 hours per charge with it on, which is the shortest single-charge life here.
5. JBL Tune Flex True Wireless Earbuds
The 12mm driver delivers the signature JBL Pure Bass thump in a stick design.
The JBL Tune Flex’s 12mm drivers are the largest in this lineup along with the GOLREX, and they deliver the signature JBL Pure Bass sound—a warm, punchy low-end that owners consistently praise. The stick form factor keeps them comfortable and secure for most ears, and the open design means you can hear your surroundings even without engaging the Ambient Aware mode.
Active Noise Cancelling here uses 2 microphones and, with Smart Ambient, lets you choose between tuning out the world or letting it in. TalkThru mode lets you pause music and have a quick conversation without removing the buds. Four mics handle calls, and VoiceAware lets you control how much of your own voice you hear during calls.
The pattern across owner experiences is a familiar one: great sound, but reliability is the recurring question mark. While some owners have bought multiple pairs and been thrilled, a notable group reports charging case failures and bud battery drain emerging after months of use. Battery life is also mixed—some report closer to 6 hours than the advertised 8 hours on a single charge.
What Shines
- Large 12mm drivers deliver a warm, bass-heavy JBL signature sound
- Flexible fit—works with or without ear tips
- Smart Ambient and TalkThru make it easy to stay aware
What Gives Pause
- Reliability is a real concern—several reviewers point out charging issues over time
- Reported battery life often falls short of the 8-hour claim
Grab these for: the warmest, most bass-forward sound in this price range and a secure open-ear feel.
Skip them if: long-term durability and consistent battery life are your top priorities.
6. JBL Tune Buds
A 48-hour total battery and Bluetooth 5.3 make these a long-haul companion.
If the Tune Flex is about the bass, the JBL Tune Buds are about stamina and connectivity. The Tune Buds pack a 48-hour total battery life (12 hours in the buds, 36 more in the case), which is the second-highest total on this list behind the GOLREX. That is more than double the 22-hour total of the Sony WF-C510, making this the pick for people who hate carrying chargers.
The 10mm drivers still deliver the JBL Pure Bass sound, though they are slightly smaller than the Tune Flex’s 12mm units. The real upgrade is Bluetooth 5.3 with LE audio support, which streams to each earbud independently so you can use either bud solo, and offers lower power consumption. Owners describe the sound as punchy and lively, with clear vocals.
The most common complaint is the fit. While many find them comfortable, the Tune Buds get the most negative fit feedback of any product here, with a high number of owners finding the stock tips don’t stay put. Several reviewers solved this by swapping in third-party foam tips. This is a case where you may need to experiment with tips to find your perfect seal.
Raw stamina: 48-hour total battery life plus Bluetooth 5.3’s efficient, independent-bud streaming make this a low-maintenance daily driver.
The catch: the fit is the weak point—budget for third-party foam tips if the stock ones won’t stay in your ears.
7. GOLREX Active Noise Cancelling Earbuds
The over-ear hooks and 80-hour battery make it the undisputed workout workhorse.
The GOLREX earbuds are built for one thing above all: staying in your ears during intense movement. The flexible over-ear hooks wrap around your ear for a security that standard in-ear buds, like the Sony WF-C510, simply cannot provide. Owners praise the secure fit during workouts, runs, and cycling, with no pain even after hours of wear.
At 80 hours, the total battery life is the highest on this list by a landslide. The charging case has a 600mAh capacity and a dual LED display that shows the battery status of both the case and the buds, so there’s no guesswork before you head out. A quick 10-minute charge gives you 2 hours of listening when you are in a rush.
The 13mm dynamic drivers, the largest here, deliver deeper bass and clearer vocals, and the adaptive hybrid ANC reduces ambient sound by up to 50dB. The case supports both wireless charging and Type-C, and physical buttons prevent accidental touches during workouts—a smart choice for active use.
Built for Action
- Over-ear hooks guarantee a secure fit for running and gym sessions
- Massive 80-hour total battery life with the case and LED display
- Large 13mm drivers deliver rich bass and clear highs
Keep in Mind
- Over-ear hooks are bulkier than standard buds for casual use
- Only a small review base so far, so long-term durability is unproven
Choose this if: you need earbuds that physically cannot fall out during a workout and want to charge them less than once a week.
Think twice if: you prefer a minimalist, low-profile look for office or casual wear.
Understanding the Specs
IP Water Resistance
The IP rating tells you exactly how much water and dust your earbuds can handle. An IPX7 rating, like the EarFun Free 2S, means the buds can be submerged in up to 1 meter of water for 30 minutes—fine for a full-on downpour. An IPX4 rating, like the Sony WF-C510, means protection from splashes and sweat only. If you’re a heavy sweater or run outdoors, the higher rating is a real safety net.
Bluetooth Version & Codecs
Bluetooth 5.3, found in the Sony, Nothing, and JBL Tune Buds, is the latest standard and offers more stable connections and lower power consumption than the older 5.2 in the EarFun and Soundcore. Codecs like LDAC (on the Soundcore Space A40) allow for higher-quality audio streaming, but only if your phone also supports it. For most users, a stable connection matters more than the Bluetooth version number.
