EARFUN OPENJUMP · NEW
Hook into your playlist.
Stay open to your day.
Bring music along without sealing your ear canals. OpenJump uses a curved earhook fit and a speaker positioned beside the ear opening, with app sound settings and a matching case for your daily routine.
Open-ear fit with flexible ear hooks
14.2mm wool-composite drivers
BassSurge sound processing
Bluetooth 5.3 multipoint and LDAC
Four-microphone call processing
Up to 11 hours; 42 with the case
OPEN-EAR LISTENING
A different fit.
A little more openness.
The curved hooks support the earbuds around your ears while speakers direct sound toward the openings. Adjust the position for comfort and consistent sound, especially if you also wear glasses.
A SOUNDTRACK FOR THE DAY
Give your playlist
room to move.
14.2mm wool-composite drivers work with BassSurge sound processing. LDAC is available with compatible sources. Open-ear bass and loudness depend on speaker placement and surrounding noise.
FIND YOUR POSITION
Built around
your everyday movement.
The three-point earhook design supports each earbud. Check the fit before activity and choose a moderate volume. Outside sound can remain audible, but this does not guarantee awareness of hazards.
CALLS ALONG THE WAY
Your voice.
Your next conversation.
Four microphones and AI call-noise processing help manage the outgoing voice signal. This is microphone processing, not listening ANC; OpenJump remains an open-ear listening design.
KEEP A TOP-UP CLOSE
More of the playlist.
Less time looking for a cable.
With LDAC off, rated playback is up to 11 hours per charge and 42 including the case. LDAC on is rated up to 8 and 30.5 hours. Both USB-C and compatible wireless charging are supported.
ADJUST IT TO YOUR DAY
Find your sound.
Connect your devices.
Use Bluetooth 5.3 multipoint with two compatible devices, and explore EQ, controls and supported sound modes in the EarFun Audio app. The earbuds carry an IPX7 rating; the charging case must stay dry.
The details,
all in one place.

Battery ratings, compatibility and care
Battery figures are manufacturer-rated maximums, not guaranteed runtime. Volume, calls, codec, noise-control settings and use affect results. Advanced codecs and app features require compatible devices and current supported software. Noise-reduction illustrations show manufacturer features; real-world performance varies.
Water-resistance ratings apply to the earbuds, not the case. Do not swim or shower with them. Wipe away sweat and let the charging contacts dry before charging.
A few things
worth knowing.
Is OpenJump bone conduction?
No. It is an open-ear air-conduction design: speakers send sound through the air toward the ear openings.
Does it block outside noise?
No listening ANC is specified. Its open fit leaves surrounding sound audible; microphone noise processing is intended for calls.
Can I use it with glasses?
The hooks share space behind the ears with glasses arms. Check the fit and comfort with your own frames before exercise.
Which color will I receive?
Choose your color in the option selector before adding to cart. Your selected option determines the supplied finish. Screen settings and lighting can affect its appearance.
