Introduction
The EarFun OpenJump are a set of earbuds that offer open-ear sound for the person who doesn’t want their ears blocked up on commutes or when working out.
On top of keeping you more aware of your surroundings, it also offers features support for streaming high resolution audio, wireless charging and a companion app for greater control over the audio.
It’s achieving that for less than the Bose Ultra Open Earbuds and Sony LinkBuds Open while offering a look adopted by other buds that might make them ones you want over any other.
Price
The EarFun OpenJump launched in January 2025 and are available to buy through EarFun’s website and retailers like Amazon. It’s already dropped from its £99 launch price and can be picked up for £69.99 or as low as £52 from Amazon.
That puts the OpenJump firmly in the same pricing territory as open-ear earbuds like the Shokz OpenFit Air (£94), the Huawei FreeArc (£79), which are both two very good, similar-looking options at this price. You’ve also got the Soundcore AeroFit (£99), which does sit at the same price as the OpenJump.
That does make them considerably more affordable than more high profile earbuds like the Bose Ultra Open Earbuds (£299) and Sony LinkBuds Open (£179).
Design
- Familiar earhook design
- Uses touch controls
- IPX7 water resistance rating
The OpenJump offers a design that’s become a settled look for open-ear earbuds that includes the likes of the Shokz OpenFit Air and Huawei FreeArc.
It’s an ear hook design that uses titanium alloy and silicone to make sure they sit comfortably on and around your ears. The IPX7 water resistance and what EarFun calls ‘Sweatshield’ technology are there to protect against rain and sweat.
Each earbud weighs 7.8g, lighter than the Shokz OpenFit Air (8.7g). The weight is nicely balanced to ensure they stay put and don’t move even during more rigorous exercise.
There are four built-in microphones to handle calls and on the outside lie a set of touch-enabled controls. These can be customised from the EarFun phone app to assign those controls differently across the two earbuds.
Those controls let you tap to adjust volume, skip back or forward a track, summon your smartphone assistant, turn on the game mode and redial a missed call. The controls however aren’t great, even when stationary. It generally took an extra tap to get them to work and a challenge to do that with controls assigned to multiple taps.
The charging case is compact enough to slip into a pocket, with a single LED light up front to let you know when they’re charging, syncing or setting up with a single physical button to initiate that pairing process. Unlike the buds, the case doesn’t have the same protection against water.
Features
- App support
- LDAC Bluetooth
In the EarFun companion app (iOS and Android) there are a host of audio modes to dabble with. There’s a dedicated game mode designed to reduce audio latency. A theater mode for watching films and TV and that offers a wider, more immersive sound.
You also have a set of EQ presets for hip-hop, metal, electronic and classical music. If those don’t work, there’s a custom equalizer option available. If you’re picky about the quality of audio streaming over the Bluetooth 5.3 connectivity, the LDAC mode enables higher quality audio though you’ll need to sacrifice the dual device connection mode to use it.
Battery Life
- Up to 42 hours battery in total
- Wireless charging
The battery life is good overall as well. It can deliver up to 11 hours when not in its LDAC mode and that drops to 8 hours when enabled. You’ll get anywhere from 30-42 hours in total depending on use of that mode with a fully charged case.
I found that an hour’s use at the most comfortable listening volume and with the LDAC mode disabled saw battery drop by 10%. With it enabled, an hour’s listening did see a more severe drop.
Compared to earbuds like the Bose Ultra Earbuds Open, Shokz OpenFit Air and Huawei FreeArc that’s more battery life you get to play with. Plus, the earbuds charge fully in an hour with support for wireless charging.
Sound Quality
- Bright, open-ear sound
- EQ presets and custom EQ mode available
- Up to 11 hours battery life
The OpenJump uses air conduction as opposed to bone conduction. This typically means you can have more control over the sound profile compared to bone conduction headphones and don’t have to worry about that vibration tickle at louder volumes.
There’s a 14.2mm wool composite driver in each bud to deliver sound along with technology geared to providing deep and powerful bass. The OpenJump has also been designed to reduce sound leakage experienced on many open-ear earbuds.
The best way to describe how the OpenJump’s sound is that they are pretty punchy open-earbuds. EarFun promises plenty in the bass department and they deliver on that front. It does however come at the expense of enjoying a balanced sound, but they offer a very enjoyable experience, whether you’re using them while wandering around, sitting at your desk or for workouts.
The true test for open-ear earbuds is how they handle outside sounds and while I found that windier, blustery conditions posed problems for the OpenJump, they offer enough volume and power to ensure they didn’t get drowned out by traffic or other noises in more crowded environments.
In terms of that sound quality, on Moderat’s Bad Kingdom, it manages to keep its composure while delivering a pleasing thump of bass that sees the mids and trebles relegated ahead of prioritising power and some unexpected open-ear roar.
Morcheeba’s The Sea showcases a more grainy than sparkly treble performance, where mids threaten to be a little too boxy. Fleetwood Mac’s Rhiannon once again shows off some grainy trebles and mids that are pretty smooth and enjoyable.
When you factor in the control with the EQ options and Bluetooth streaming quality, the OpenJump handled most of what I threw at it without major issues. What it lacks in balance and clarity both for audio and calls it makes up for with an energetic sound that gives it good versatility across a range of genres.
Should you buy it?
You want powerful, open-ear earbuds at a good price
The EarFun OpenJump delivers powerful, enjoyable sound and offers better value than similarly priced earbuds.
You want the most elegant-looking open-ear earbuds
While they do sit snug and securely on your ears, there are definitely more discreet open-ear earbud options you can grab instead.
Final Thoughts
The EarFun OpenJump perhaps have one of the worst names attached to a set of wireless earbuds, but it makes up for it with its satisfying open-ear sound, a comfortable and pretty reliable fit and scope to tinker with the sound that’s pretty good out of the box.
If you can pick it up at its reduced price, it’ll make a great alternative to the excellent Shokz OpenFit Air and give you a more secure fit in more scenarios than considerably more expensive options like the Bose Ultra Open Earbuds.
