Wireless Earbuds

Buying wireless earbuds is all about three things: sound, silence, and convenience. Strex earbuds combine all three — active noise cancelling (ANC) filters out ambient noise, Bluetooth 5.3 ensures a stable, glitch-free connection, and the LED display on the charging case shows exactly how much battery life remains. Available in white and black.

What does active noise cancelling actually do?

ANC is not just a thicker earbud that blocks sound — it is technology that actively produces anti-noise. Tiny microphones measure ambient noise, and the earbuds send back an exactly inverted sound wave, causing constant droning to vanish: train engines, the hum of an airplane, the buzz of an open-plan office. Voices and sudden sounds remain audibly muffled — that is normal and even safe in traffic. Anyone seeking peace while commuting, studying, or flying will notice the difference within a single train journey.

What should you look for when choosing?

• ✔ Noise cancelling — active (ANC) dampens constant noise; passive isolation alone is noticeably less effective
• ✔ Bluetooth version — 5.3 means a more stable signal, lower power consumption, and less lag during videos
• ✔ Battery indicator — an LED display on the case prevents the classic surprise of a dead case on the go
• ✔ Fit — multiple sizes of silicone tips determine both comfort and how well ANC works: a leaky seal lets noise in
• ✔ Warranty — 2 years standard with Strex

The fit determines half your sound

The most underestimated detail of in-ear earbuds: the silicone tip. If the tip is too loose, bass leaks out and ANC has to work harder against incoming noise — it then sounds thin and the silence is disappointing. After purchase, test every size of tip included: the right size seals softly without pressure, and you will hear the difference immediately in the low tones. This takes two minutes and is the difference between "fine earbuds" and "why does this sound so good".

Frequently asked questions

How long does the battery of wireless earbuds last?

The earbuds themselves play for several hours on a single charge; the charging case recharges them multiple times on the go. The LED display on the case shows the remaining percentage, so you never head out with an empty case — you can see before you leave if recharging is necessary.

Can I still hear traffic with ANC on?

Yes. ANC primarily dampens constant, low-frequency sound such as engine noise and humming. Car horns, voices, and sudden sounds remain audibly muffled. For cycling in heavy traffic, the following still applies: use one earbud or turn off ANC — remaining aware of your surroundings remains your responsibility.

Do wireless earbuds work with iPhone and Android?

Yes, with both. Bluetooth is a universal standard: pairing works identically on iPhone and Android via the Bluetooth menu. After the first pairing, the earbuds connect automatically as soon as you open the case — regardless of your phone brand.

What is the difference between ANC and passive noise isolation?

Passive isolation is simply the seal created by the silicone tip in your ear. ANC adds active technology to that: microphones measure ambient noise and the earbuds produce anti-noise that filters it out. The combination of a good fit and ANC provides the most silence.
