## Description

Product Description EarFun OpenJump Open Ear Headphones

Review: Exceptional sounding open ear headphones - Having used the Open Jump for a few days now I am very impressed, especially for the price so I thought I would share my experience so far. For those you have never used this type of "open ear" headphone - it actually sits outside your ear and has effectively a 'little speaker' which does not touch your ear at all but directs the sound into your eardrum. I have attached a picture of it and you will see it is very different than a normal TWS or IEM. This makes it incredible comfortable for those you don't like anything in their ears. I left it in my ear during a full working day and I completely forgot I was wearing it. But because everyones ears shape is different and therefore it will sit either nearer or further away from your eardrum depending on the size of your ears, it is vital for good sound to use the "My Sound Profile" feature within the EarFun App. This process takes you through a sort of "listening" tests but once you do this you get an excellent sounding TWS. The nice thing is once I created this custom profile, I can hear my music very clearly (I will get into my sound impressions in a second) but nobody around me can hear anything yet I can hear conversations going on around me clearly ( which is important in my day job when in a shared office ). Obviously this type of earphone is designed for runners / bicyclists who need to hear everything around them clearly but it will work well if you have to stay connected to those around you but still want to enjoy listening to music (or listening to podcasts). Audio wise, they have some excellent midrange and pretty decent treble and while the bass does roll off (which is to be expected with such a open design) but you do get reasonably nice mid-bass, so most bass heavy tracks will still sound reasonable. Overall I found the sound profile to be more than acceptable, though obviously since it is designed to allow you to hear everything around you, you won't get any sound "isolation" so if you are in a noisy environment this is probably not the audio device to be using. I also measured the Open Jump and I have shared a measurement of how it looks compared to "Harman" using "my custom profile" and this graph shows that excellent midrange and treble but does also shows that bass roll-off. I did try some extra EQ to boost the bass but I felt that was causing some "distortion" as the little "speaker" was struggling but depending on your ear shape that might work well. The battery life has also been outstanding as I mentioned I left it on all day in work and switched between music and going on some work calls and it lasted a full 8 hours. The microphone quality also was pretty impressive especially indoors (though I did go for a walk and it worked fine until it got a bit windy). So, overall I think it is a fantastic device and one which I will be using most days when I am in a shared space and need to continuously talk too and listen to my colleagues.
Review: Excellent - I have other Open Ear wireless earbuds to compare ( OneOdio the oldest and the very first Shokz produced , Huawei FreeArc ). The Earful Open Jump is by far the best fitting for my ear because the loudspeaker is nearest to my ear canal ( lower position compared to others) . It is as comfortable as Shokz . Sound is very good , nearly as good as the Shokz . Bluetooth range is also the same as the others except Huawei FreeArc ( Huawei better range ). I bought it during the sale and for the price I paid this is the best value for money out of all of them. Recommended .

### ⭐⭐⭐⭐ Great sound and comfort - awful controls.
*by T***O on 5 February 2026*

My second Earfun product, previously had their earbuds for several years which always surprised me with their clarity. These are even better, with better presence and low end response. Now, they are NOT comparable to over-ear headphones but you won't miss them entirely. Bluetooth connectivity is better, and more stable and the option for LDAC is a nice option. They are comfortable and fit well for long periods. The silicone has some flexibility which makes it simple to get a good fit. I forget in wearing them. Although, the controls are just garbage. The touchpad is angled backwards which makes muscle memory hard for me. And they are a bit too sensitive, getting commands wrong is easy, there's just no consistency in how they respond. I'm keeping them anyway as the sound quality is great, but the tap controls on my previous Earfun earbuds were just superior.
