Powerful bass and 30-hour case

ViewSonic P20i true wireless earbuds use 10 mm dynamic drivers to deliver boosted low-end response for music lovers who want impactful bass in a compact in-ear form. Bluetooth 5.3 provides stable connectivity up to 10 metres while the charging case extends total playtime to 30 hours. A 10-minute quick charge adds two hours of listening when the buds are low. The IPX5 water-resistant rating and included lanyard make them suited for active daily use.

Upgrade from basic buds lacking app EQ

These replace entry-level true wireless models that offer no sound customisation or multipoint convenience. The ViewSonic app unlocks 22 preset EQ profiles and a "Find My Earbuds" feature that emits a locating tone. Instant pairing connects automatically to the last paired device after the initial setup. Passive noise isolation and dual microphones with an AI algorithm improve call clarity without requiring active noise cancellation hardware.

Suits commuters and gym-goers wanting bass and app

Buyers who prioritise strong low frequencies, long case battery life and EQ personalisation will appreciate the feature set. The lightweight ABS and polycarbonate shell with a pocket-friendly case suits on-the-go listening. Shoppers who need active noise cancellation, wireless charging or high-resolution codec support should look at alternative models that include those technologies.

Questions about this item

What size are the drivers inside the ViewSonic P20i earbuds?

The earbuds use 10 mm dynamic drivers to produce the boosted bass response.

How do I pair the earbuds for the first time and what step do people often miss?

Open the charging case, remove both earbuds and they enter pairing mode automatically; the step users miss is taking both buds out together so the handshake completes.

How long does the charging case last before it needs to be recharged itself?

The case holds enough power for 30 hours of total playtime before you must plug it in again.
