Run with the street in earshot and the music still on. The T35 hooks over the ear, rotates to fit, and keeps the ear canal open to traffic. A claimed 60+ hours of total endurance means the case gets charged far less often.
Open-ear sport earphones with over 60 hours of total battery endurance
- earbuds falling out during exercise
- need to hear surroundings while running
- frequent charging
Hear the street, keep the music, skip the charger
Earbuds that pop out and ears that go deaf to traffic are the usual trade-off. The T35 hooks over the ear, stays put on the move, and runs over 60 hours of total endurance between charges.
The hook that stays put on every stride

A hook that holds on the move
The 90 degree rotatable hook seats over the ear and holds through stride and sweat. Turn it until it sits snug, then start moving. A loose hook lets the bud shift, so set it before the warm-up. Pair it with wireless earbuds you already trust for indoor sessions.

Hear the street and the playlist
The open design leaves the ear canal uncovered. The 25 degree directional sound transmission aims audio toward the ear, so the music stays with you while the street stays audible. Keep volume moderate in quiet places, since open designs carry sound outward.

Know your charge before you leave
The case shows battery level on a digital LED, reading 100 at full charge. L and R indicators on the case tell you which bud goes on which side. Glance at it before you leave the house.

Seat it once, then forget it
- 1Rotate the hook
Turn the 90 degree hook until it lines up with the curve of your ear.
- 2Seat the bud
Hang the hook over the top edge of your ear so the bud rests just outside the ear canal.
- 3Check the hold
Take a few strides and turn your head. If it shifts, rotate the hook once more and recheck.
- 4Read the case
Look at the LED on the case before you leave. A reading of 100 means the charge is full.

From the bud on the hill to a week of training
The bud that dropped on the hill
A sealed bud shifts on the third hill and you spend the rest of the run pressing it back in. The other ear goes quiet, so the cyclist behind you becomes a guess until the horn is already close.
Open ears, secure fit
The T35 hooks over the ear, and the 90 degree rotating hook grips so the earphone stays seated through stride and sweat. The ear canal stays open, so traffic, footsteps and your pace come in alongside the music.
A week of training, one charge
Charging stops being a daily chore. The case and earbuds together carry a claimed 60+ hours of total endurance, and the LED on the case shows the charge before you head out the door.
What a training block looks like
- First useFit check before your first run
Rotate the hook until it sits snug over the ear, then run a short loop to confirm it holds. Adjust once if it feels loose.
- 3 usesSettling into open-ear listening
Most people stop noticing the open design after a few sessions. Traffic and footsteps start to sit alongside the music without reaching for volume.
- 30 daysCharging becomes occasional
With regular training, the case LED becomes a quick glance rather than a daily worry. Battery use depends on volume and listening habits.

Questions and answers
Yes, when it is seated properly. Rotate the 90 degree hook until it grips snugly over the ear before you start moving. A hook that is left loose will let the bud shift on each stride, so take ten seconds to set it before the warm-up.
Open-ear designs leak some sound outward, so keep volume moderate in quiet rooms and on trains. Bass sounds lighter than a sealed earbud, which is the trade for hearing traffic. If you want sealed sound for a desk or studio, check over ear headsets instead.
Yes. The packaging claims more than 60 hours of total endurance across the case and earbuds together. Daily use depends on volume and listening habits, so a training block of several weeks is realistic before you need to think about charging.
Yes. The ear canal is left uncovered, and the 25 degree directional sound keeps the music aimed at your ear. Cyclists, footsteps and conversations stay audible while you listen, which is the point of the design.
The LED shows the battery level of the case, and it reads 100 when the charge is full. L and R indicators on the case show which bud belongs on which side, so you can check both the charge and the pairing before a run.
You get two earbuds and a charging case in one set, built from glossy plastic with a silver ring accent and an orange-lined case. The return on the purchase is practical: a bud that stays put on hills and a case that shows its charge, so you stop paying in lost focus and mid-run stops.
