Name: NL25
Brand: Valco

Question 1

Active noise cancellation doesn't seem to stop wind or outside noise as well as it should. Wind blows straight into the microphones and it sounds like you're sitting in the eye of a storm.

Accepted Answer

Update your headphone firmware via the Valco app and make sure the headphones fit snugly on your ears.

Question 2

Customer is looking for the best noise-cancelling headphones under a €200 budget and wants an honest comparison.

Accepted Answer

Spoiler: a Finnish company does surprisingly well.

Question 3

Customer is looking for earbuds for running and exercise and doesn't know what to pick.

Accepted Answer

NL25 stays in your ear and handles sweat. Don't run with over-ear headphones.

Question 4

Customer commutes on public transport and wants headphones that preserve their sanity.

Accepted Answer

ANC is the best thing to happen to public transport since the bus pass.

Question 5

Customer is looking for the best true wireless earbuds and doesn't know what to pick.

Accepted Answer

NL25 if you want ANC and wireless charging, NL21 if you want long battery life and a fair price.

Question 6

Customer is wondering if noise-cancelling headphones are suitable for air travel

Accepted Answer

Yes you can, and ANC is honestly the best thing that can happen to your ears on a plane.

Question 7

Valco headphones, earbuds, or speaker won't charge at all, or charging seems to start but the battery doesn't actually fill up. The charging light might blink weirdly or the device doesn't react to the charger at all.

Accepted Answer

Try a different USB cable and a different charger – surprisingly often the cable is the culprit, not the device.

Question 8

The lights on the charging case keep blinking for a long time even after unplugging the charging cable. The blinking eventually stops on its own, but it's a bit worrying.

Accepted Answer

Stop charging and restart the headphones – if the issue persists, check the charging port and cable condition.

Question 9

Headphones start independently switching between ANC and transparency mode in an endless loop. Even shutting them down doesn't work normally.

Accepted Answer

Reset the headphones and check the user manual for the correct button presses.

Question 10

The open-plan office drives you crazy; colleagues’ chatter and keyboard clatter never stop

Accepted Answer

ANC is an open-office worker’s best friend. Colleagues won’t be offended.
