1More Fit Open SE Review: Are the S30 Open Ear Earbuds Worth It?

Do you want earbuds that let you hear the world around you? Maybe you run at dawn, ride your bike in traffic, or just hate the plugged feeling of regular earbuds. The 1More Fit Open SE (sold as the 1MORE Fit SE Open Earbuds S30) promises comfort, clear calls, and long battery life for a small price.

I dug through specs, lab tests, and hands-on reviews to see if it delivers. This review covers sound, comfort, battery, calls, and more. By the end, you will know if this pair suits you or if an alternative fits better.

In a Nutshell

Short on time? Here is the quick summary of the 1More Fit Open SE.

• Open ear design for safety: The earbuds rest outside your ear canal. You still hear cars, people, and bikes around you. This makes them a smart pick for outdoor runners and cyclists.
• Big 14.2mm DLC driver: 1MORE uses a large dynamic driver with a diamond like carbon diaphragm. A bass boost feature called DBB adds some punch. Bass is still lighter than regular earbuds, which is normal for open ear models.
• Excellent battery life: You get 10 hours per charge and 30 hours total with the case. One tester got 13 hours at 50% volume, which beats the official claim.
• Clear calls with 4 ENC mics: Four microphones and an AI algorithm cut background noise. Your voice sounds natural on calls, even outdoors.
• IPX5 and a secure fit: The ear hooks hold each 10 gram earbud in place during workouts. IPX5 handles sweat and rain, but not swimming.
• Great value: The list price is $69.99, and it often sells for around $50 to $55. Check the current price, since deals change often.

1MORE Fit SE Open Earbuds S30 Overview

Last update on 2026-10-16 / Affiliate links / Images from Amazon Product Advertising API

The 1MORE Fit SE Open Earbuds S30 is the budget model in 1MORE’s Fit series. Many people search for it as the “1More Fit Open SE.” The model number is EF606.

1MORE is a headphone brand started by former Xiaomi and Foxconn executives. The company builds budget headphones, and it now runs an R&D center in San Diego, California. Its Fit series targets active people who want open ear sound.

The S30 sits below the pricier 1MORE Fit S50. Both use a bar shape with an ear hook. The S30 drops the small ear tip found on the S50. Instead, a flat metal grille covers the driver and aims sound into your ear.

Here are the key specs in plain terms. Each earbud weighs 10 grams. The case weighs 59.7 grams. Each earbud has an 85mAh battery, and the case holds 600mAh.

The driver is a 14.2mm dynamic driver with a DLC diaphragm. Bluetooth 5.3 supports the SBC and AAC codecs. The wireless range is about 10 meters.

You also get four ENC microphones, touch controls, and an IPX5 rating. In the box, you find the earbuds, the case, a short USB Type C to Type A cable, and paperwork. 1MORE backs the product with a one year limited warranty.

So who is this for? It fits people who want awareness and comfort more than deep bass. If you want earbuds that block the world, look at sealed models instead. If you want to stay alert on the road, keep reading.

Design and Build Quality

The first thing you notice is the matte plastic finish. It feels smooth and does not pick up fingerprints easily. Reviewers at APH Networks called the build very sturdy and expected it to last.

Each earbud has a bar shaped body. A flexible ear hook wraps over the top of your ear. The outer face of the bar works as a touch panel. The inner face holds the speaker grille and two metal charging pins.

The look is simple and clean. It looks a lot like open ear designs from Bose and Cleer. You can find it in colors like black and white, so you can pick a style you like.

The charging case is solid too. The lid closes firmly and the earbuds snap into place with magnets. However, the case is on the large side. It is longer and narrower than the S50 case, so it slides into a pocket a bit more easily. Still, it is much bigger than an AirPods case.

The earbuds feel well made for the price. There are no creaky seams or loose parts. The touch surface is large, so you will not miss your taps.

The ear hooks are the one design point that splits opinion. Some reviewers found them flexible and gentle. Others found them a bit stiff, especially for glasses wearers. We will cover this more in the comfort section.

Overall, the design is practical and tidy. It does not try to be flashy. It just aims to stay on your ears and survive daily use, and it does that job well.

Comfort and Fit

Comfort is the main reason people buy open ear earbuds. Nothing goes inside your ear canal, so there is no pressure and no plugged feeling. Many people find this much nicer for long sessions.

At just 10 grams per earbud, the S30 is light. The weight spreads across the hook and the bar, so it does not pull on your ear. The rounded edges also help it rest softly against your skin.

The Phonograph gave the S30 a comfort score of 9 out of 10. Its reviewer praised the gentle but secure fit and the fatigue free feel. That is a strong result for a budget product.

Not every tester agrees, though. APH Networks found that the hooks became uncomfortable after a long time. eCoustics noted the hooks felt stiff for someone who wears glasses. In that test, the S50 felt more comfortable than the S30.

So what does this mean for you? Fit depends a lot on your ear shape. If you have medium or large ears, the hook will likely feel fine. If you wear thick glasses frames, the hook and the frame arm may compete for space.

Here is a simple tip. Put on your glasses first, then slide the hook in front of or behind the frame arm. Test both spots and see which feels better.

For workouts, the fit is very secure. Reviewers ran, jumped, and moved their heads without the earbuds falling. One YouTube reviewer even titled his video “These Won’t Fall Out!” That says a lot about stability.

Top 3 Alternative for 1MORE Fit SE Open Earbuds S30

The S30 is a great value, but it is not your only choice. Here are three strong alternatives that solve some of its weak spots.

1. 1MORE Fit Open Earbuds S50

The S50 is the big brother of the S30. It uses a PurePower dual magnet driver for stronger bass and higher volume. It also has a small tip that sits near your ear opening and guides the sound.

The S50 is rated IPX7, so it handles heavy rain and water much better. It also offers wireless charging, fast charging, and up to 38 hours of total playtime. The trade off is a higher price and no custom EQ in the app.

2. Soundcore V20i by Anker

The V20i is a top budget pick. It has adjustable ear hooks, so it fits more ear shapes. It also supports Bluetooth 5.4 and multipoint, so you can pair two devices at once.

You get up to 36 hours of total playtime and an IP55 rating. It usually costs less than the S30. Sound leakage is also fairly low for the price.

3. Soundcore AeroFit 2 by Anker

Last update on 2026-10-16 / Affiliate links / Images from Amazon Product Advertising API

The AeroFit 2 is the premium pick here. Its ear hooks have four adjustable positions for a custom fit. It offers rich bass, Hi Res audio support, and wireless charging.

Battery life reaches up to 42 hours with the case. It costs more, but it is a big step up in features and sound. Choose it if you want the best open ear experience without going to Bose prices.

Sound Quality

Let us talk about sound. Open ear earbuds have a natural limit. Without a seal, bass escapes into the air. So you should expect lighter bass than regular earbuds.

1MORE fights this with a large 14.2mm driver and DBB bass boost. The result is solid mid bass punch. Drums and beats still feel lively. However, deep sub bass is weak. APH Networks found kick drums and bass guitars a bit light and hollow.

The midrange gets mixed reviews. eCoustics found vocals pushed forward and very intimate. The singer sounds close and centered. The Phonograph also praised the full and clear vocals for both male and female singers.

APH Networks heard it differently. Its tester noticed a small dip in the vocal range and called the overall tuning an inverted W shape. This shows how much fit and ear shape change open ear sound.

The treble is clean and fairly bright. Cymbals and strings have good air. The tuning also controls harsh peaks and sibilance well. That means long sessions do not tire your ears.

At max volume, bass can start to sound boomy. Still, APH Networks noticed no electronic distortion at full volume, which is a good sign.

Here is the key tip. Placement matters a lot. Move the earbud slightly until the grille points straight at your ear opening. You will hear a clear jump in bass and detail when it sits right.

Overall, the S30 sounds better than most budget open ear earbuds. It suits podcasts, pop, and workout playlists very well. Bass lovers may want the S50 or AeroFit 2 instead.

Soundstage and Sound Leakage

The soundstage is one of the S30’s biggest strengths. Open designs create space that sealed earbuds cannot match. Music feels like it comes from around you, not from inside your head.

APH Networks said live recordings felt as if you were actually there. eCoustics noted the S30 had a wider and deeper stage than the S50. The reason is simple. The S30 has no tip near the ear, so sound spreads out more freely.

Instrument separation is good too. Vocals, guitars, and electronic sounds stay distinct even in busy tracks. Layering is clean and easy to follow. For a budget pair, that is impressive.

Now for the downside. Open designs leak sound. The S30 leaks more than the S50, again because it lacks the tip. If you play music loudly, people near you will hear it.

This matters in quiet places. Think libraries, open offices, or a quiet train. In those spots, keep the volume at around 50% or lower. People nearby will then hear very little.

Outdoors, leakage is a smaller issue. Wind and traffic cover most of the sound. At the gym, the music around you also masks it.

Here is another point. Open ear earbuds do not block noise. On a loud bus, you may need to raise the volume. This is the trade off for staying aware of your surroundings. For runners and cyclists, that awareness is a safety feature, not a flaw.

Call Quality and Microphones

The S30 packs four ENC microphones, two in each earbud. ENC stands for environmental noise cancellation. It works with an AI algorithm to cut background noise on calls.

Here is an important point. This noise cancelling only helps the person you talk to. It does not block noise for you. You will still hear the world around you, as an open ear design should.

In testing, call quality was very good. APH Networks recorded samples indoors and outdoors. The voice sounded natural and clear in both places. A fan in the background got picked up a bit, but it did not distract from the voice.

This makes the S30 handy for daily calls. You can take a work call while walking the dog. You can call a friend on a quick run. Your voice will come through clearly.

The open design also helps you on calls. You hear your own voice naturally, so you do not shout. Sealed earbuds often make people talk too loudly because their own voice sounds muffled.

Wind can still be a challenge, as with most earbuds. In strong wind, callers may hear some noise. Turning your back to the wind helps a lot.

For the price, the S30’s mics beat many rivals. If you take lots of calls on the move, this is a solid reason to pick it. It works well for quick calls and casual voice memos.

Battery Life and Charging

Battery life is a standout feature of the S30. 1MORE claims 10 hours per charge. The case adds two more full charges, for 30 hours in total.

Real tests beat those numbers. APH Networks got about 13 hours at 50% volume on one charge. That is three hours more than promised. Very few earbuds in this price range last that long.

What does 10 to 13 hours mean in real life? You can run every day for a week and only charge once or twice. You can wear them on a long flight without worry. You can use them through a full workday too.

Charging takes some patience, though. The earbuds need about 90 minutes to charge fully. The case needs about 120 minutes. Both charge through a USB Type C port.

There are two missing features here. First, the S30 has no fast charging. A quick 10 minute top up will not give you hours of music. Second, the case does not support wireless charging. You need a cable every time.

The included cable is short at 27cm. It also uses a USB Type A plug on the other end. Many people now use Type C chargers, so you may want a Type C to Type C cable.

If you need fast or wireless charging, the S50 or AeroFit 2 is a better fit. For most users, though, the long battery life makes up for it. You simply will not charge it very often.

Connectivity, Touch Controls and the 1MORE Music App

The S30 uses Bluetooth 5.3. Pairing is quick on both iPhone and Android. It supports the SBC and AAC codecs. There is no aptX or LDAC, so high resolution streaming is not an option.

The connection is strong. APH Networks kept a clean signal beyond 10 meters without drops. That is better than the official range. In a pocket or armband, you should have no trouble at all.

Latency is low enough for videos. Some testers noticed a slight delay in games, but most people will not notice it. YouTube and Netflix look fine.

The touch controls sit on the large outer panel of each earbud. You can tap to play, pause, skip tracks, and answer calls. You can also call up your voice assistant. The big surface makes taps easy, even while running.

The free 1MORE Music app adds more control. You can change what each tap does. You can update the firmware. Most importantly, you get a custom 10 band EQ.

The EQ is a big plus. You can raise the low bands to add more bass. You can also lower the treble if the sound feels too bright. eCoustics praised this feature and noted that even the pricier S50 lacked a custom EQ at launch.

One thing is missing. The S30 does not list multipoint support, so you cannot easily switch between a phone and laptop. If you need that, the Soundcore V20i is a better choice. Still, for most people, the app and controls work well.

Water Resistance and Workout Performance

The S30 carries an IPX5 rating. This means it can handle sweat, splashes, and rain. Water jets from any angle should not damage it.

So what can you do? You can run in light rain. You can sweat through a hard HIIT class. You can rinse off the earbuds gently after a workout.

What should you avoid? Do not swim with them. Do not dunk them in water or shower with them. IPX5 is splash proof, not waterproof. If you need full waterproofing, the S50 has an IPX7 rating.

For workouts, the S30 shines. The ear hooks keep the earbuds in place during running, jumping, and lifting. The 10 gram weight means you barely feel them. Reviewers called the fit secure and stable during exercise.

The open design is also great for the gym. You can hear a trainer’s instructions. You can talk to a workout buddy without removing an earbud. You can hear your own breathing, which helps with pacing.

Outdoor use is where the S30 really matters. Runners can hear cars and horns. Cyclists can hear other riders coming up behind them. This situational awareness can prevent accidents.

One small tip helps here. Wipe the charging pins dry before you put the earbuds back in the case. Sweat on the pins can cause charging issues over time. A quick wipe with a soft cloth keeps them working well.

Pros and Cons

Every product has strong points and weak points. Here is a clear look at both sides of the 1More Fit Open SE.

Pros

• Long battery life: It lasts 10 hours per charge, and tests show up to 13 hours. The case brings the total to 30 hours.
• Comfortable open ear fit: Nothing enters your ear canal. Many users can wear it for hours without pressure.
• Secure for workouts: The ear hooks keep the earbuds steady during runs and gym sessions.
• Clear call quality: Four ENC mics deliver natural voice quality indoors and outdoors.
• Wide soundstage: Music sounds open and spacious, much like small speakers near your ears.
• Custom 10 band EQ: The app lets you shape the sound to your taste.
• Solid build: The matte finish resists fingerprints and feels durable.
• Great value: It often sells for around $50, which is low for this feature set.

Cons

• Light bass: Deep bass is weak, which is common for open ear designs.
• Sound leakage: It leaks more than the S50, so watch the volume in quiet places.
• No fast or wireless charging: You need a cable and some patience to recharge.
• Bulky case: The case is large and can feel bulky in a pants pocket.
• Stiff hooks for some users: Glasses wearers may find the hooks less comfortable over long sessions.
• Only IPX5: It is not safe for swimming or full water exposure.
• No aptX or LDAC: It only supports SBC and AAC codecs.

Overall, the pros outweigh the cons for most buyers. The weak points mostly come from the budget price and the open design. For around $50, these are fair trade offs.

Who Should Buy the 1More Fit Open SE?

This earbud is not for everyone. Here is a simple guide to help you decide.

Outdoor runners and cyclists are the best match. You stay aware of traffic while you enjoy music. The secure hooks and IPX5 rating handle sweat and rain. The long battery covers many sessions.

Gym goers will also like it. You can hear trainers and friends without pulling out an earbud. The light weight keeps you comfortable through long workouts.

Office workers and remote workers can benefit too. The open fit is great for long calls. You can hear a coworker or a doorbell while you listen. Just keep the volume low in quiet offices.

People who dislike in ear buds should consider it. If regular earbuds hurt or feel itchy, the open design is a relief. Nothing sits in your ear canal.

Now, who should skip it? Bass lovers will feel let down. If you want heavy, deep bass, choose sealed earbuds or the S50.

Commuters on loud trains may also struggle. Open earbuds do not block noise. You will need to crank the volume, which causes leakage.

Swimmers need a different product. The S30 cannot go underwater. Look for an IPX8 or bone conduction swim model instead.

Finally, audiophiles may want more detail and codec support. The lack of LDAC limits sound quality. For them, the AeroFit 2 is a better step up.

Final Verdict

So, is the 1More Fit Open SE worth buying? For most active people, the answer is yes.

It gets the basics right. The fit is secure. The battery life is excellent. Calls sound clear. The open design keeps you safe outdoors. And the price stays friendly to your wallet.

Reviewers mostly agree. eCoustics called it a real bargain and said you would be hard pressed to find better at its sale price. APH Networks rated it 6.8 out of 10 and called it a solid open ear option for the price. The Phonograph scored its comfort at 9 out of 10.

The weak spots are clear too. Bass is light. Leakage is noticeable at high volume. The case is bulky and lacks fast or wireless charging. Some users may find the hooks stiff over time.

Here is my simple advice. If you want an affordable, comfortable open ear pair for running, the gym, or calls, buy the S30. If you want stronger bass and full waterproofing, spend more on the 1MORE Fit S50. If you want adjustable hooks and multipoint on a tight budget, try the Soundcore V20i.

In short, the 1More Fit Open SE delivers more than its price suggests. It is one of the easiest open ear picks to recommend for everyday active use.
