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.

Good buy
I decided to give these a try as I'm unable to wear inear headphones and find them really comfortable. The sound quality is good and I like the fact that I can hear what is going on around me when I'm out walking. I do put my glasses on after I've fit the headphones to help them stay in place

Good headphones for their purpose
I got these because I like to cycle and find that in ear buds don't always stay secure. These aren't designed to go in the ear but to sit over them. They are headphones not earbuds. They can take a little adjustment so they sit 'right' This can be achieved by bending the tube material and holding it for 12 seconds so that it retains its place. This made a huge difference to the volume and tone of these and is well worth doing. I set them up in the brilliant Earfun app and configured the EQ to my tastes (You also get tons of presets). They have a nice tone and stayed secured to my ears for the 8 mile bike ride. These don't have noise cancelling so I felt safe wearing them whilst riding as I could hear the traffic around me. Sound quality was pretty good and I could hear the finer details in songs. Bass was good and I could really push the deepness if I wanted. Higher frequencies were very clear. The app allows you to do things like customise controls, turn on theatre mode or game mode, switch on Dual device connection, set the time before they shutdown and send a tone to them to find them if you've mislaid them. You will also get firmware updates through the app which are always worth installing as Earfun are very pro-active at updating things. They charge quickly and in the time I was wearing them I'd hardly made a dent in the battery usage. You can get 2 hours use with only 10 minutes of charging. Overall, once I'd adjusted them correctly, (It's worth watching Earfun's videos on how to do this) I found that I enjoyed wearing them and forgot about them whilst out and about doing more sporty activities which is what they are designed for.

Great sound and comfort - awful controls.
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.

So near yet so far
The first annoying problem is getting the box open I am surprised at how good they and are very acceptable .... BUT .... If they fitted over the ear canal , which they dont, they would be brilliant. The only way to make them sound as they should is to adjust the frequency range (equaliser) If the arms had a wire in them you could adjust so the little speaker sat central i would be very satisfied. Ought to send them back really but will attempt to adjust them. Would appreciate help from earfun.

Very good quality
Great - love these, fantastic sound quality and good battery life. Decent app and like the "find me" option as they do drop out when taking t shirts off....

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 .

Would definitely recommend
These are excellent value, keep their charge well and are comfortable to wear

Bin ziemlich begeistert. ๐ซถ๐ป๐ค
Nutze die Ohrhรถrer hauptsรคchlich beim Sport (Laufen/Trailrunning und Indoor-Radtraining - โnackigโ, also ohne Mรผtze oder Bandana, wรผrde ich sie beim Outdoor-Radtraining wohl eher nicht verwenden (Windgerรคusche!)). Der Halt ist dabei sehr gut und die Ohrhรถrer sitzen, ohne zu wackeln. Sie sind sehr leicht und bequem (bei pausierter Musik wรคhrend des Laufens dachte ich manchmal, ich hรคtte einen Ohrhรถrer verloren, weil ich ihn nicht spรผrte, aber das war nicht der Fall ๐ ). Auch bei viel Schweiร (Rad Indoor) nerven sie nicht รผbermรครig - sammelt sich hierbei jedoch etwas zu viel Schweiร in den Ohrmuscheln, kann es vorkommen, dass die Touch-Bedienung vorรผbergehend nicht/nicht richtig funktioniert (beim Laufen ist mir das noch nicht passiert). Die Akkulaufzeit ist sehr gut. Der Funktionsumfang mit der App ist absolut top - es lassen sich mehrere EQ-Profile anlegen, die direkt auf den Ohrhรถrern gespeichert werden. Auch die Steuerung (Touch-Inputs) lรคsst sich individuell konfigurieren oder deaktivieren. Nun aber zum Klang (for what it's worth: beruflich bin ich im Audio-Bereich unterwegs und mut neutral abgestimmten Lautsprechern und Kopfhรถrern vertraut und auch im Umfeld der Musikproduktion alles andere als unwissend, Letzteres aber nur als Hobby/Leidenschaft/Spezialinteresse): fรผr Ohrhรถrer dieser Art ist er wirklich sehr gut. Was die Abstimmung betrifft: bereits die Grundeinstellung ist รผberraschend ausgewogen โerwachsenโ und nicht รผbertrieben bassig oder hell, sondern der etwas wรคrmeren, bassigeren Spielweise zuzuordnen, mit angedickten, aber nicht dumpf klingenden unteren Mitten und einem ganz sanft in den Hintergrund tretenden Hochton. As it is kรถnnte ich bereits absolut zufrieden mit dieser Grundabstimmung leben, habe in der App per EQ jedoch den zu warmen Grundton/unteren Mittelton abgesenkt, den Bass etwas reduziert und die oberen Mitten und den mittleren Hochton etwas angehoben. Somit klingen die Ohrhรถrer nun zwar immer noch โpunchyโ genug im Oberbass (der Tiefgang ist allgemein fรผr die Bauweise normal/okay, aber man sollte sich bewusst sein, dass unterhalb von 85 Hz der Pegel abrollt - meine anker AeroFit 2 bieten etwas mehr Tiefgang, jedoch auf Kosten einer im Vergleich zu den EarFun schlechteren Detailwiedergabe, Prรคzision und Gleichmรครigkeit im Hochton (dass die Anker in ihrer Grundabstimmung vรถllig daneben und รผbertrieben basslastig abgestimmt sind, sei mal dahingestellt, denn auch sie bieten eine App mit EQ-)), jedoch ohne unnรถtige Wรคrme. In meiner Abstimmung ist der Hochton/obere Mittelton nun etwas neutraler/prรคsenter, aber ich habe dennoch eine ganz milde Absenkung im Prรคsenzbereich gelassen, da ich beim Training hier keinen stets perfekt neutral analytischen Klang mรถchte (daher auch der trotz Absenkung im Tiefton von mir noch immer leicht betont gelassene Kickbass). Anyway, die generelle Detailwiedergabe, Instrumententrennung, Bassprรคzision und blah haben mich fรผr diese Bauweise und den Preisbereich doch ziemlich positiv รผberrascht: so kommen beispielsweise Bรคsse ziemlich prรคzise rรผber und selbst schnelle Doppelbass-Punches sind noch als solche erkennbar. Insgesamt muss man aber realistisch bleiben, denn die EarFun lรถsen letztlich nicht ganz so gut auf wie gute kabelgebundene In-Ears mit dynamischem oder Balanced Armature Treiber. Aber ganz ehrlich, besonders wรคhrend des Trainings vermisse ich hier absolut nichts, ganz im Gegenteil, sondern bin noch immer ein wenig begeistert davon, wie verhรคltnismรครig sauber und prรคzise die Ohrhรถrer sind (meine prinzipiell vergleichbaren Anker sind, obwohl ich sie per EQ einigermaรen รคhnlich wie die OpenJump abgestimmt habe (die OpenJump bieten definitiv die deutlich bessere EQ-Basis als die AeroFit 2), hรถrbar weniger prรคzise/gut auflรถsend und im Bass schwammiger (Doppelbรคsse verschwimmen, bei den OpenJump hingegen nicht)). Das (fรผr mich) absolute Highlight der Ohrhรถrer, neben ihrer hohen Convenience (was war noch gleich das deutsche Wort dafรผr? ๐ ), ist aber ihr Hochton: dieser ist so linear, homogen und frei von schmalbandigen Peaks oder Senken, sodass er sehr natรผrlich und realistisch klingt (bestรคtigt mit Sinus-Sweeps und rosa Rauschen โ ein Traum). Ganz ehrlich, besser geht's kaum, und sehr viele wesentlich teurere In-Ears, Ohrhรถrer und Kopfhรถrer sind den gรผnstigen OpenJump teils deutlich unterlegen, was die Gleichmรครigkeit und Natรผrlichkeit im Hochton betrifft (looking at you, Sennheiser HD 800 ๐ โ waren definitiv ein Fehlkauf, wenn ich bedenke, dass meine HD 600, die zwar schlechter auflรถsen und im Bass weniger prรคzise sind, die deutlich gleichmรคsigere und realistischere/natรผrliche Abstimmung besitzen โ aber das hat jetzt mit den EarFun eigentlich wenig zu tun ๐ซฃ). Ach ja, und Rauschen gibt's รผbrigens auch nicht und die Verbindung รผber Bluetooth ist einwandfrei stabil und ohne Aussetzer. Bin ich klanglich und auch generell zufrieden? Absolut, ja.

Good choice if you're not aiming at the stars
Good design and finish. Good packaging. Works as advertised (it's not the best in its class, but delivers a lot price wise). Haven't tested the battery time up to its limits.

Unbelievable Value and Quality - These are it!
I bought these after days and days of wireless headphone reviews on Youtube and Tik Tok. I will say these have blown me away. Now as a disclaimer - I wasn't looking for the best quality headphone to begin with. I was looking for an affordable headphone specifically for running and some in gym workouts and I didn't see a reason to buy an over the top headphone to get sweaty in. I wasn't shopping for sound quality either as I have a pair of Apple Airpod Max's which I am content with in every other scenario. But when I tell you that these headphones exceeded my expectations from every aspect I truly am impressed. I knew I didn't want true in ear headphones (especially for running) and these I found to be a very comfortable and fine blend of right on the ear comfortably. I've had soundshocks (bone conduction) and Air conduction headphones - these ones are air conduction which I actually prefer - especially with higher volume or more vibrational/bass pumping songs or audio (podcasts on loud are not ideal feeling on bone conduction - too much vibration). They feel and fit comfortably in my ear, they come with instructions on how to properly wear them for best sound and comfort. I can still run and hear most things around me (mainly car traffic - gets harder to hear people talking or low noise pollution). I haven't needed to turn the volume up past 45-55% the sound is plenty loud with good quality sound all around and plenty loud - I haven't even needed to try max volume in any instance and I do waterside (windy) and street (traffic noise) and have found that mid range level to be more than loud enough with the way the sound funnels into your ear. There is some bass (definitely audible) however it's not going to give you the same bass as in ear or more powerful over the ear headphones (but again i didn't get them for that), surprisingly stacks up great though and I feel/hear good enough bass for the purpose of these. It has clear quality sound even while listening to podcasts on a walk - crisp and clear voices. The battery life is supposedly ridiculously long (11+ hours) which is amazing and i'm sure with more time with them that will be put to the test but I have had them 2 weeks now and haven't needed to charge them at all. They still have 30% battery straight out of the box (I also don't run for hours lol - I'll wear them maybe 1 hour a day or less). The case conveniently charges wirelessly or plug in and is light to carry even though it's a bit bigger than an airpods case. The functionality was decent, I am still getting used to the touch controls but they are pretty responsive even with sweaty ears/fingers. They are 2 taps for play/pause (good feature so they don't accidentally activate from sweat drops or hair which would happen more if it was a one touch). 3 taps to skip and you hold it down to activate siri. So far works well for me while running and walking but devices with physical buttons will obviously be easier to use with greater feedback. Volume control is a tap swipe which was cool! Love them so far and I'd say for under $50 (amazon prime day) they outcompete the cost and almost value of more expensive $100+ headphones that people traditionally buy for their sporty/running headphones (Shokz, Beats, Bose).
