How to Choose Wireless Earbuds: ANC, ENC and Battery Life
د White Apple Communications لخوا
Choose wireless earbuds around your main use: listening to music, taking calls or gaming on your phone. Noise-control labels, microphone information and playback figures can help you narrow the choice, but they do not replace a sound-quality or comfort assessment.
ANC and ENC describe different priorities
Active noise cancellation, or ANC, is a listening feature intended to reduce outside noise you hear. ENC is used in these Voco listings for environmental noise control during calls. A model that lists ENC without ANC should not be assumed to provide active noise cancellation for music.
Microphone count alone does not prove how well earbuds handle wind or a busy street. Call quality depends on the product’s processing, fit, surrounding noise and connected device. This guide compares listed features and does not claim hands-on audio testing.
Compare the Voco earbuds in the catalog
| Model | Noise control | Microphones | Playback time | Low-latency feature |
|---|---|---|---|---|
| Voco S-01 | ENC | Not listed | Up to 7 hours | Not listed |
| Voco S-02 | ANC + ENC | Quad microphone system | Up to 8 hours | 66ms |
| Voco S-03 | ANC + ENC | Quad microphone system | Not listed | 45ms game mode |
Voco S-01 lists ENC, a 13mm dynamic driver and touch controls. Voco S-02 lists ANC and ENC, quad microphones, up to 8 hours of playback and 66ms latency. Voco S-03 lists ANC and ENC, quad microphones, a 45ms game mode and an LED battery display on the case. A playback-time figure is not supplied for S-03.
Compare battery figures on the same basis
S-01 lists up to 7 hours of playback and S-02 up to 8 hours. These maximum figures are not guarantees under every listening condition. Both list a 400mAh case, but a separate total runtime including case recharges is not provided. Case capacity alone cannot establish how many hours of listening you will get.
Think about calls, games and fit
If calls matter most, compare the microphone and call-noise-control information. If you want ANC for listening, compare the models that actually list it. For gaming, check whether the latency figure applies to a particular mode; the 45ms S-03 figure is explicitly a game-mode specification. A lower listed figure does not guarantee identical results in every game or app.
Check comfort, charging connection, available colour and device compatibility before ordering. A Bluetooth version number does not, by itself, verify support for every feature on every phone.
Does water resistance mean earbuds are suitable for swimming?
No swimming suitability is established by these listings. S-02 lists IPX4 water resistance; check the manufacturer’s use and care instructions instead of treating water resistance as a general waterproof claim.
