Why OpenEar ?
IP68 waterproof
8GB onboard
6Hr+ Battery LifeMost “waterproof” earbuds mean “survives a sweaty run.” Tempo is sealed to IP68 and rated for submersion to two metres of fresh water — pool lengths, open water, rain, the shower afterwards. Sweat isn’t a threat here. It’s the baseline.
After open-water or salt-water use, rinse in fresh water and dry before charging.

Here’s what nobody tells you about waterproof earbuds: Bluetooth doesn’t travel through water. Your phone can be sitting a foot away at the end of the lane and the signal still dies.
That’s why Tempo carries its own music. Load your playlist onto 8GB of onboard storage,³ leave your phone in the locker, and swim your set with a soundtrack.
Underwater playback uses onboard MP3 mode.² Bluetooth 5.3 handles everything above the surface.


Two transducers rest on your cheekbones and send sound through the bone. Your ear canals stay completely open — so you hear the scooter behind you, the coach across the pool, the cyclist calling your left.
Music on. Guard up. No trade.
Keep the volume at a level where you can still hear traffic around you.⁴

Bone conduction gives you clear, energetic sound with real detail while you’re working. We’ll be straight with you, because you’d find out anyway: if what you want is chest-thumping bass in a silent room, sealed over-ears win that contest.
Tempo wins every contest that happens outside.

No two loose buds waiting to divorce mid-workout. Tempo is a single flexible band that wraps behind your head and locks over your ears — 34 grams, so you stop noticing it by the second lap.
It fits under a swim cap. It survives burpees. It shares space with glasses and helmet straps.

“Once I were through how to add music to my headphones MP3 files using these has been a great addition to my swimming. The sound is clear and they are super comfortable to wear.”
“What a great discovery. The sound is amazing, and the fit very comfortable.”
“I have a smaller head the the headphones Re stiff on the band so If I dont sit them right they jut put just wnough tahg it feels weird. I tuck the band up under my hat lr sit it above me pony tail to keep them from putting too much pressure on my temples from them trying to hang on. Otherwise I love them. They sound great. When I have them sitting right I forget they are there. If I have them turned all the way up it drowns everything else without them blaring and no one can really hear them if I have them up all the way.”
Train in them. Swim in them. Sweat in them. If Tempo isn’t the best training partner you’ve owned, send it back within 30 days for a full refund — no forms, no argument. A real person answers, and we make it right.
Yes — that’s what they’re built for. Tempo is IP68 rated for submersion to 2 metres of fresh water. Use the onboard MP3 mode in the water, since Bluetooth doesn’t transmit through water. Rinse in fresh water after the sea or a chlorinated pool.
Tempo has 8GB of storage built in. You load your playlist onto the headphones over the charging cable, switch to MP3 mode, and leave your phone in the locker. Above water, Bluetooth 5.3 connects to your phone as normal.
Bone conduction sends sound through your cheekbones rather than into your ear canal, so you get clear, punchy audio and still hear the world. Honestly: it trades some deep bass for total awareness. That’s the whole point of the product.
It’s one flexible band that wraps behind your head, not two loose buds. It holds through laps, sprints, and burpees, and it fits under a swim cap. If it doesn’t stay put on your head, the 30-day guarantee covers you.
Yes. The band sits light against your head, so most glasses and sunglasses share the space fine, and cycling or climbing helmet straps don’t fight it.
[X] hours of playtime on a full charge, and a magnetic cable takes it back to full in about [X] hours. [CONFIRM these numbers with your supplier before launch.]
Delivery is free and included in the price, arriving in [X–X] days with tracking. If they’re not for you, send them back within 30 days for a full refund, plus a 12-month warranty against defects.
Your music and your world, together — in the pool, on the road, everywhere. Try Tempo risk-free for 30 days.
