Product overview
Open-ear sport earbuds
Open-ear running earbuds leave the ear free: the speaker sits in front of the ear canal, not in it. So you hear your music and, at the same time, the cars, the cyclists and your coach. Every model here is a sweat-resistant Bluetooth sport earbud (IPX4 or IPX5) weighing under 10 grams a bud.
Choose by how you want them to sit on the ear:
– With a hook, for sprints and the gym: the TESNA GOG100 (9.4 g, IPX5, 42 hours with the case) and the TESNA GOJ05, the lightest hook pair at 8.1 g.
– With a clip, for glasses wearers and cycling: the TESNA Ola 1 (6.8 g, IPX5, 36 hours with the case) clips onto the rim of the ear and does not clash with glasses arms or a bike helmet strap.
All of them connect to iPhone and Android. Prices from 59 lei, with delivery in 1–3 days and 14-day returns.
Not sure which to pick? Read Open-ear or in-ear earbuds for running and GOG100 vs GOJ05.
Earbuds for a marathon and long runs need to be light and to last: the GOJ05 weigh 8.1 g a bud, and the GOG100 last 42 hours with the case.
WHAT TO CHECK
The IP code: IPX4 handles sweat and splashes, IPX5 water jets, IP55 and IP56 add dust protection. None is made for swimming.
Battery: look at the hours per charge and what the case adds.
All connect over Bluetooth to iPhone and Android.
WHY OPEN-EAR FOR RUNNING
On the road or the track it is safer to hear what is around you. Open-ear earbuds do not close the ear, so there is no pressure after an hour and you do not hear your own footsteps through the bud. The sound has less bass than in-ear earbuds, especially in loud traffic. Our guide on open-ear or in-ear for running explains the differences in full.
WHAT SPORTS THEY SUIT
They are light wireless sport earbuds with no cable between the buds, for running and trail running, cycling, hiking and walking, tennis, CrossFit and the gym. Because they stay out of the ear and send sound through the air (air conduction), they do not press or heat the ear during a workout, and the big battery lasts a week of training.

QUESTIONS
What people ask us before they buy
Do they fall out when running?
The hook models (GOG100, GOJ05) have a titanium core that holds the bud in place through sprints and burpees. The Ola 1 clips onto the rim of the ear.
Can I run in the rain with them?
Yes. IPX4 handles splashes and sweat, and IPX5 water jets too. They are not made for swimming.
Can people around me hear my music?
At moderate volume, very little. The speaker points into the ear canal.
GOG100 or GOJ05?
The GOG100 has a bigger driver (16.2 mm) and 42 hours with the case. The GOJ05 is lighter (8.1 g) and cheaper. The full comparison is in GOG100 vs GOJ05.
