EarFun OpenJump Review: Why I Couldn’t Wait to Take Them Off

I love listening to music, so I never thought I’d find earbuds that made me want to stop — but that’s what happened with EarFun OpenJump.

These open-ear earbuds are made for fitness, sitting outside your ears so you can still hear what’s happening around you. This design is great for running or working out safely.

But sadly, the OpenJump earbuds didn’t impress me. The sound quality was poor — the mids sounded thin and bad on almost every song, no matter which of the 30 EQ presets I tried. The touch controls were hard to use, and the call quality was really bad too.

EarFun OpenJump Price & availability Review

EarFun OpenJump earbuds are priced at $79 on Amazon U.S. and £99 on Amazon U.K., making them one of the more affordable options in the open-ear earbuds market.

They’re cheaper than rivals like the Soundcore AeroClip ($129) and Shokz OpenFit 2 ($179), both of which performed well in tests.

However, the OpenJump earbuds come only in black. While black is neutral and safe, it’s a bit disappointing since many other brands offer more color choices.

EarFun OpenJump Design & controls Review

EarFun OpenJump earbuds have a black, rubbery finish that looks cheap. While the earbuds feel sturdy, the ear hooks seem low quality — the plastic feels flimsy, and the rubber discolors quickly.

EarFun says the adjustable hooks can handle 7,000 bends, but since I had to readjust them often to fit properly, I’m not sure they’ll last that long.

Honestly, they’re not the best-looking earbuds. If you want something that stays in place and looks better during workouts, the JLab JBuds Sport ANC 4 ($69) offers a sleeker design with more color options.

Even the JLab Go Air Sport earbuds, priced at just $30, might be a better pick. Though they’re not open-ear, they feel better and look nicer — and at that price, it’s easier to accept the average sound quality.

On the bright side, the EarFun OpenJump earbuds are lightweight, and only the ear hook reminds you they’re there. They also come with an IPX7 rating, meaning they’re protected against sweat and rain — making them suitable for outdoor workouts.

Controls: EarFun OpenJump earbuds have touch controls on the silver logo, but they don’t work well. Most of the time, my taps didn’t work, so I just used my phone to change songs or pause the music.

Even small things, like moving my hair, would accidentally pause the music or turn on Siri.

You can change the controls in the EarFun app. I turned off most of the controls and only kept ‘skip track’ on the right earbud and ‘previous track’ on the left. This made it easier to use.

The charging case is small and fits easily in a pocket or bag. It feels a bit cheap, but that’s okay for the price. Some cheaper earbuds still have better cases, though.

EarFun OpenJump Comfort Review

EarFun OpenJump earbuds have a rubbery finish to help them stay in place, but even light movement made them feel loose. I tried adjusting the ear hooks, but after just five minutes of walking, they started slipping.

If you wear glasses, ear hooks are uncomfortable. I had to switch to contact lenses while testing because wearing both felt annoying. If you wear glasses often, open earbuds without hooks—like Soundcore AeroClip—are better option.

One good thing is the open-ear design. It helped me stay aware of my surroundings, especially near traffic. I could hear cars while waiting to cross the road and didn’t need to take the earbuds off.

Still, there are better options out there with the same open-ear design but better sound and a more secure fit—like the Soundcore AeroClip or Shokz OpenFit 2.

EarFun OpenJump Connectivity & mic performance Review

LDAC Support but Poor Call Quality

The EarFun OpenJump earbuds come with Bluetooth 5.3 and support SBC and LDAC codecs. SBC is standard, but LDAC is nice because it allows high-resolution audio over Bluetooth.

The Bluetooth range is about 15 meters, but when I left my phone upstairs and went to the kitchen, the sound cut out. None of my other earbuds have this issue, so it was annoying.

You can also connect two devices at once, like your phone and computer, which worked well for me.

The earbuds have 4 mics for reducing background noise during calls. I tested this while walking near a busy road. My mom said she could hear me clearly, and the traffic noise was faint.

But on my end, the call quality was bad. My mom’s voice sounded robotic with static, like a voice changer was on. When I called back using my phone’s speaker, everything sounded normal. Unfortunately, the earbuds’ call quality was disappointing.

EarFun OpenJump Sound Quality and EQ Performance Review

Sound quality is not good. The default sound is bad, so you must adjust the EQ in the app. After setting my custom sound profile, the music sounded a little better and clearer. This feature helps if you have hearing problems or want safe listening.

Still, the sound has issues. The mids sound weak and tinny on almost every preset. Only the custom profile was okay.

EarFun says the BassSurge feature improves bass, but it didn’t work. Even after boosting the bass, songs sounded muddy, and the mids became robotic.

Songs with drums sounded bad and had crackling noises. Only soft songs like Call Your Mom by Noah Kahan sounded fine because they were simple.

Another problem is sound leakage — people sitting far away could hear my music.

EarFun OpenJump App Review

The EarFun app works with the OpenJump earbuds and helps improve their performance a bit, but the app is clunky and not easy to use.

The main menu looks like iPhone settings, but it’s not user-friendly. Only the EQ section looks good and is easy to navigate. The app has 30 EQ presets and a My Sound Profile test, which helps adjust the sound to your hearing.

There are also Game Mode and Theatre Mode, but they don’t do much. Game Mode is supposed to lower sound delay for gaming, but I didn’t notice a big difference. Theatre Mode just made the sound louder but still tinny.

EarFun OpenJump Battery Life Review

Battery life is one of the good things about the EarFun OpenJump earbuds. They last up to 11 hours on a single charge. I listened for 4 hours and still had 70% battery left.

With the charging case, you get a total of 42 hours of playtime. The case supports wireless charging or you can use a USB-C cable to charge it.

Conclusion

EarFun OpenJump earbuds left me disappointed. Yes, they’re affordable, but the sound—especially the midtones—is really bad.

The open-ear design is good for staying aware of your surroundings, and the custom sound profile in the app helps make the music sound a bit better. But honestly, that’s the only good thing.

The touch controls don’t work well, calls sound robotic, and no matter which EQ setting I tried, the music—especially rock songs—sounded terrible.

It’s better to spend $30–$40 more on better earbuds that you’ll actually enjoy using.
