Where TESNA has got to

These are the figures TESNA publishes globally. Market availability, series and specifications can change without notice. A serial check confirms the unit left a TESNA line; it does not replace the commercial warranty your seller gives you.

AUTHENTICITY

Check that they are real. In thirty seconds.

Every TESNA product carries a unique serial with a check digit. It cannot be guessed and it is not easy to copy.

This confirms the serial's format, not the product's history. For full confirmation, send us the serial on WhatsApp.

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.

CONTACT

Tell us what you are looking for. We answer with a price.

One message, not a long form. Tell us what you do with earbuds and we tell you which model fits and what it costs.
