QUESTIONS

What people ask us before they buy

Are the earbuds I buy genuine?

Every product carries a serial with a check digit, on the box and under the lid. You check it above in thirty seconds. If the serial does not pass, do not buy.

What warranty do I get and where do I repair them?

Two years, through the dealer you bought from. Keep the receipt and the box. If you cannot find the dealer, message us with the serial and we tell you where to go.

Do they fall out when I run?

The open-ear models sit on a hook, not in the ear, and the hook has a titanium core. They do not come off at a sprint.

Do calls sound good?

The microphones filter noise. In a busy city the person hears you, but strong wind still comes through. We say that plainly.

How long does the battery last after a year?

Around 85 percent of the original life, at one charge a day. Lithium-ion batteries decline, and ours do too.

Can I try them somewhere?

Yes. We have dealers and partner stores. Message us on WhatsApp with your city and we send you the nearest one.

Earbuds for teenagers: what matters when you choose

How teenagers use earbuds

Teenagers use earbuds almost all day: on the way to school, at break, during homework, at sport and in the evening for games or series. Their buds go through school bags, pockets and changing rooms, so they need to be tough and simple to use.

The most important thing, though, is not the earbuds but the volume. Young people's hearing is sensitive, and the habit of listening loud for hours can leave lasting marks. A volume limit set on the phone helps more than any model.

Set a volume limit

On iPhone: Settings, Sounds and Haptics, Headphone Safety, then turn on "Reduce Loud Audio" and choose a limit. So it cannot be changed, under Screen Time, Content and Privacy Restrictions, you can lock this setting. On Android, many phones have a media volume limiter in the sound settings; where it is differs by brand.

On iPhone, the Health app also shows how loud headphone audio has been, by day and week.

Toughness for the school bag

True wireless buds live in their case, which protects them in the school bag. Choose a case that closes well and buds with sweat resistance, IPX4 or more, for PE lessons. The Buds4 are IPX4 and connect by themselves when you open the case, with no settings each time.

The case is the part most often lost or dropped. A separate pocket in the bag helps a lot.

Battery for a school day

A school day, with the journey both ways and the breaks, means a few hours of listening. Buds with 7–9 hours on a charge and a case that recharges them last a full day. The Buds4 last 7 hours on a charge and 28 hours with the case; the GTA02 9 hours and 36 with the case.

The habit of charging the case in the evening, along with the phone, saves mornings with flat buds.

For games

Many teenagers play on their phones, and in games sound delay matters. The GTA02 have a gaming mode with a latency of about 60 ms, so the sound arrives with the picture. Our guide to earbuds for phone games explains it in full.

In games too, moderate volume matters: long sessions at high volume tire the hearing.

For sport and on the street

For running, cycling or walking to school, open-ear buds are the safest: the ear stays free, so the teenager hears cars and bikes. The GOG100, with a hook and IPX5, stay put at sport and handle sweat.

On a bike or scooter, the simple rule is that ears stay free; isolating in-ear buds are not suitable there.

A conversation, not just a setting

A volume limit helps, but habits matter more. An easy rule to remember: if someone next to you can hear your music from the buds, it is too loud. Breaks now and then rest the ears, and noise cancelling buds in noisy places allow a lower volume.

Ringing in the ears after loud listening is a sign of hearing fatigue; if it happens often or does not go away, see an ENT doctor. Our guide to safe volume gives more detail.

How to talk about volume

Many teenagers listen loud because they want to drown out the noise of the bus, the playground or home. An argument that works better than a ban: buds that seal well or have noise cancelling let them hear music just as well at a lower volume. The simple explanation that tired hearing does not repair itself helps too.

Set the volume limit together, not in secret, and leave it at a level where music sounds good in their usual places. A limit that is too low is soon got round, while one agreed together is kept more easily. For games and series in the evening, over-ear headphones, which do not go into the ear, are a comfortable alternative too.

Every model is in the shop, under true wireless earbuds.
